I Think My Vegetables are Nutritious

Nutrient Declines in Fruits and Vegetables

Growing vegetables is really quite simple. You put the seeds or transplants into sunny ground, you water and weed, and then you harvest your bounty. For that small effort, you can put on your plate food that is organically, sustainably, and (very) locally grown. Perhaps even richer in nutrients than food you can buy.
Healthy, healthful, vegetables
Studies over the past 15 or so years have documented a general decline in nutrients in our fruits and vegetables. Some people contend that our soils have been mined for their nutrients, worn out from poor farming, and therefore no longer able to provide us with nutritious food. The cure, according to these “experts,” is to sprinkle mineral-rich rock powders on the soil to replenish and rebalance that which has been lost. It all sounds very logical.

You might have sensed a big “but” looming. Here it is: But . . . further studies have pinned that nutrient decline on a dilution effect from increased yields. Pump up production with nitrogen fertilizer and water, or by breeding for increased yields, and nutrient concentrations decline; it’s as simple as that.

The final nail in the “worn out soil” coffin comes from side-by-side plantings of low- and high-yielding varieties of specific vegetables. The higher yielding varieties end up with lower concentrations of minerals and protein. The problem, then, if there is one, can be blamed on breeding and farming practices aimed at producing more bulk.

But . . . 

I’m not concerned with nutrient decline in my own garden. First of all, I’ve chosen the varieties I grow — Blue Lake beans, Cherokee Purple tomatoes, Lincoln peas, Early Jersey Wakefield cabbage, Ashmead’s Kernel apple, and Fallgold raspberry, as examples — with

one thing in mind: flavor! Peas in podIt just so happens that the most flavorful fruit and vegetable varieties are ones that have been around a long time. Yields may not be heavy, but these varieties are rich in flavor. (And perhaps nutrients. Anyway,

Ashmead's Kernel apple

Ashmead’s Kernel apple

if something doesn’t taste that good, I’m not going to eat much of it, so it’s irrelevant how high it is in nutrients.)

I’m also not concerned with nutrient decline because I don’t push yields to the max with repeated applications of soluble, nitrogen-rich fertilizers. My soil management is simple: One inch of compost per year spread on top of the ground of permanent vegetable beds; compost, wood chips, hay, and/or leaves around my fruit plants. As these organic materials decompose, nitrogen and other essential nutrients are bled slowly into the soil only in response to warm temperatures and moisture, the same environment that spurs plant growth.
Spreading compost
That compost is not serving up only nitrogen to my plants, or even just the big three nutrients, nitrogen, phosphorus, and potassium. Into my compost goes orange peels from Florida, avocado skins from California, and other kitchen waste, garden trimmings, some weedy hay, and, occasionally, horse manure. So the ground gets a wide variety of organic materials that, in turn, feed the compost and, in turn, feed the soil and the plants a wide spectrum of nutrients. And just to make sure that my soil lacks nothing, I occasionally sprinkle some powdered kelp around.

Herbs for Flavor, in Winter, Not Nutrition

Even if herbs were rich in nutrients, their nutritional contribution to our diets would be minimal because of the relatively small amounts actually eaten. But the small amounts needed to pizazz up a tomato sauce or frittata in winter also make herbs ideal for growing indoors in winter. A little goes a long way. 

The basic problem is that many cooking herbs are Mediterranean plants that, of course, thrive best in Mediterranean conditions, with bright hot sun beating down on them. So the expectations and the reality of a windowsill herb garden often diverge. Forget about growing basil or oregano in January.

With that said, I nominate two herbs perfect for indoor growing in winter. The first is bay laurel. This plant, a small tree trained as a “standard,” has spent the last 29(!) winters near a sunny window. A freshly plucked leaf brings to soups and stews a flavor only hinted at by the dried leaf; to me, in addition to its distinctive flavor I sense an oleaginous quality hinting of olive oil.

The second herb, rosemary, is my favorite for indoor growing. Rosemary tolerates being trained as a standard or fanciful topiary; it looks equally good left to its own devices to grow as a relaxed, small shrub.  (Mine are trained as standards.) Pinching off a few stem tips

with leaves not only puts some warm, Mediterranean sunshine into tomato sauce but also encourages growth of side shoots to keep the plant dense with shoots and leaves.

 

Once spring warmth has settled in around here, the bay laurel and rosemary will move outside to bask in the full force of Hudson Valley sunshine. 

FOR THE GARDENER WHO HAS EVERYTHING

How Cold? How Humid?

Do you want to send a really good gift to a really good gardener? (Perhaps that gardener is you.) Problem is that most really good gardeners have pretty much everything they need except for expendables like string, seeds, or potting soil (unless they make their own. Don’t despair; I’ve come up with a few items many really good gardeners with (just about) everything they need might find useful.

At the top of my list is a nifty, little device with the odd name of Sensorpush. It’s not much bigger than an inch square pillbox, less than 3/4 inch thick, that you place wherever you want to monitor temperature and humidity — from your smartphone, via bluetooth.

Couple it with the WiFi Gateway and temperature and humidity can be monitored from anywhere on your smartphones. I periodically checked on my greenhouse and the outdoor temperatures here in New York when I was recently thousands of miles away in Israel.

My original use for the Sensorpush was for the greenhouse, to alert me, which it can do, if  temperatures drop to a minimum that I set at 37°F. I now have another, outdoors, which alerted me to the one late frost (28°F) last spring which wiped out the crop on my peach tree. I may also put ones in my freezer and walk-in cooler. 

All past information is available graphically and can be downloaded to a computer.

Water is Important

Much, much more low-tech is my new favorite watering can. It’s not any old blue watering can, it’s the French Blue Watering Can. It has everything I would look for in a watering can: hold lots of water, in this case 3 gallons; good balance when being carried and in use; and water exiting in a stream that’s gentle but not too slow. For optimum balance, get two, one for each arm.

Although the French Blue Watering Can now beats out my previously favorite Haw’s 2 gallon, zinc plated cans, which are, admittedly, more visually elegant, Haw’s is still in the running with their beautiful, copper-enameled, 2 quart watering can that I use mostly indoors. For indoors, it’s a good volume, and the long spout can reach in among plants for more pinpoint watering once its rose is removed.

Books, of Course

I can’t help but mention books. Those that I mentioned last week were general categories; the really good gardener has, of course, some very specific interests and expertises. And there are books for these (I’ll stay away from my special interests to avoid having to mention, once again, any of the books that I have authored). 

So, for instance, if you’re interest is in unusual vegetables, you could start with A. C. Herklots’ 1972 publication Vegetables of Southeast Asia. The book is especially rich in “greens,” including shepherd’s purse (Capsella bursa-pastoris), garland chrysanthemum (now Glebionis coronaria), and honewort (Cryptotaenia japonica). Also a slew of “Asiatic cabbages.” For something even less contemporary, there have been various printings of The Vegetable Garden by Vilmorin-Andrieux,scion of the famous French seed company. In addition to many common vegetables, of which many interesting varieties are mentioned, ferret around in the book and you’ll also find some unusuals: olluco (Ullucus tuberosus), rampion (Campanula Rapunculus), and seakale (Crambe mariitima).
Books, unusual vegetables
Eric Toensmeier’s Perennial Vegetables offers a much more contemporary take on unusual vegetables. Most of the vegetables mentioned are not really perennial in cold climates but they surely are unusual. The last I heard, very few people were growing nashua (Tropaeolum tuberosum), Chinese artichoke (Stachys offinis), chufa (Cyperus esculentus var. sativa), or winged bean (Psophocarpus tetragonobolus).

Tools and Plants

Finally, I’d like to give a shout out to the five advertisers on my blog posts (to your right). These are not just any old companies that choose to advertise. They represent businesses whose products and, in some cases, owners I know and trust (by experience) to offer the highest quality products.

Let’s start with the two nurseries. Looking for a place to buy high quality plants of pawpaw, persimmon, quince, medlar, or even more common fruits. Raintree Nursery is the one. I’ve even sent them stems from some of my more unique plants to propagate. Cummins Nursery is the go to nursery for a very wide selection of varieties of apple, pear, peach, and other familiar tree fruits on a variety of rootstocks. The rootstock helps determine such tree characters as size, adaptability to various environments as well as how soon and how much fruit you’ll pick.

(Incidentally, a nursery tree grown hundreds of miles away can be just as adapted to your site as one grown around the corner. Genetics is important, so an Ashmead’s Kernel apple grown in Washington is genetically identical to one grown in New York, or anywhere else.)

With all those new plants, some tools will be needed to help care for them. For everything from high quality soil sampling tubes to grafting supplies to hoes to tripod ladders (very stable, I own two different sizes), look to Orchard Equipment Supply Company (OESCO).

If you’re looking very specifically for cutting tools — pruning shears, pruning saws, loppers, pole saws, and the like — look no further than ARS. You can’t go wrong purchasing an ARS tool. After writing a book about pruning, I was sent many samples of pruning equipment; among the shears, ARS — specifically the VSX Series Signature Heavy Duty Pruner — is my favorite, with good weight, good steel, replaceable parts, and easy opening with just a firm squeeze of the handles. They slightly edged out my Felco and Pica shears.

Scythe Supply sells just one thing: scythes. But they offer the best of the best, as well as sharpening services and instruction. Don’t expect one of those picturesque, old scythes often turning up at garage sales, more useful for decorating a barn wall than cutting tall grass. Scythe Supply scythes are super light and well balanced with blades hammered razor sharp like those of Samurai swords. One-time Congressional candidate, homesteader, and swinger of a scythe into his nineties, Scott Nearing had this to say about scything: “It is a first-class, fresh-air exercise, that stirs the blood and flexes the muscles, while it clears the meadows.” So true. I use my mowings for compost and mulch.

FRUITS OF ISRAEL

Olives Galore

Now I feel foolish buying olives. I recently returned from visiting Israel where there were olive trees everywhere. Irrigated plots of greenery thrived in the broad expanses of the otherwise grays and browns of the desert. Trees popped up here and there in backyards and front yards of homes in streets lined with apartment buildings as well as along cobblestone streets in rural areas. Trees were even prominent in city parks, either as self-sown wildings in less tended areas or as formal plantings.
Woman harvesting olives in Jerusalem park
And oodles of ripe or ripening olives were clinging to branches or littering the ground. Need some hand lotion? Just pluck a ripe olive, squeeze it gently, and spread out the fresh oil that drips onto your hand. 

Want some olives for eating? Not so fast. Fresh-picked ripe or green olives are extremely bitter (due to oleuropein). That bitterness is removed with brine, multiple changes of water or lye solution followed by fermentation. My favorite olives are “naturally, sun-cured,” which, I imagine, means left hanging on the tree a long, long time. The dried, ripe olives I found still-clinging to branches tasted awful!
Green olive fruits
I was tempted to harvest some olives to bring home. A few other people had similar ideas, as evidenced by one woman on a ladder in a park in Jerusalem. Of course, these people were only miles or less from home; I was 5,000 plus miles from home. I let the olives be.

I actually grow olives here in the Hudson Valley, in a large container that spends summers outdoors basking in sunlight and winters in my cold basement near a large window. I should say that I grow an olive tree, rather than olives. My maximum harvest has been a half-dozen olives — which I did let hang for a long, long time, at which point they tasted delicious.
My potted olive treeMy olive harest-3 fruits
Olive fruits are borne on one-year-old shoots. This year, before moving my tree to the basement, I pruned more severely than usual. That should stimulate more one-year-old shoots this spring, to, I hope, yield more fruit.

——————————————

Another of my favorite Mediterranean fruits also growing in abundance in as many guises as olive in Israel was pomegranate. Unfortunately, I just missed the harvest of this fruit. All that remained on wild plants were a few red arils still clinging to darkened portions of skins.  Fruits must have been ripe somewhere because ripe fruits and fresh squeezed juice were available in markets and and street carts everywhere. 
Pomegranate espalier, IsraelPomegranate display, Israel
I, of course, also grow pomegranate, similarly to olive except that, being deciduous, this plant does not need light in winter. It spends those months in a dark, walk-in cooler. 

Sad to admit, my yields of pomegranate fruits have been even less than my yields of olive. As in zip, zilch, zero. The plants flower every spring and with a small brush I’ve transferred pollen from the anthers of male blossoms to the stigmas of female blossoms. (Plants each have separate male and female blossoms.) Bases of female blossoms begin to swell hopefully. Then they drop.

Every year I threaten my plant with a walk to the compost pile — to no avail.

——————————————

The third plant of the triumvirate of my favorite Mediterranean fruits is, of course, figs, which I saw in abundance in Israel mostly in wild settings. The plants lacked fruit, except for a few with small, green figlets that will either drop or ripen next spring. Fig is rather unique in its fruiting habit, able to bear fruit on one-year-old wood as well as on new, growing shoots, and the latter crop just keeps forming and ripening as long as growing conditions are to its liking.
Wild olive tree in Israel
One old tree growing in a courtyard in charming town of Sfad was hosting an old friend  — or, rather, enemy — of mine, fig scale insects. I’ve battled it one my greenhouse figs.

Figs were available in the markets but I was reluctant to even try them knowing that figs must be dead ripe to taste good. At that, stage they can hardly be transported more than arm’s length from hand to mouth.
Figs for sale, Israel
Figs are one Mediterranean fruit that I grow with great success, both in my greenhouse (minimum winter temperature 37°F) and, wintering in my walk-in cooler and summering outdoors, in pots like my pomegranate. Figs are generally easy to grow because of their unique bearing habit, their lack of need for pollination, and their general tolerance for abuse.

My last day I broke down and, against my better judgement, bought some figs. Mine are better.

YOGI WAS RIGHT

To Do List

“It ain’t over ’til it’s over” said Yogi Berra, and so says I. Yes, the outdoor gardening season is drawing to a close around here, but I have a checklist (in my head) of things to do before finally closing the figurative and literal garden gate.

Trees, shrubs, and woody vines can be planted as long as the ground remains unfrozen. To whit, I lifted a few Belaruskaja black currant bushes from my nursery row and replanted them in the partial shade between pawpaw trees. A Wapanauka grape vine, also in the nursery row, is now where the Dutchess grape — berries too small and with ho-hum flavor — grew a couple of months ago. And today a couple of black tupelos are moving out from the nursery row to the edge of the woods, where their crimson leaves, the first to turn color, can welcome in autumn each year.

Kale, lettuce, endive, turnips, radishes, leeks, and celery still grow in the vegetable garden, but many beds are vacated for the season. Any remaining old plants will become food for the compost pile and the cleared off beds will then get a one-inch dressing of crumbly, brown compost from a pile put together last year.
Clearing bed of all weeds and plants in preparation for its layer of compost.
Freezing weather would burst the filter, pressure regulator, and timer for the drip irrigation system, so these components have been brought indoors. The rest of the system stays in place.

The drip system may now be out of commission but some watering may be needed. Occasional days with bright sunlight and warm mean hand watering. How primitive!

Planning Ahead, Soil-wise

Making compost for use next year, same time, same place, is also on my checklist. Especially today, so the compost creatures within the pile can take advantage of lingering warmth in the air to work overtime. A pile that gets hot cooks to death most weed seeds and pests that hitchhike into the pile on what I throw in. And I throw in everything, in spite of admonitions from “experts” to keep diseased or insect-ridden leaves, stems, or fruits out of compost piles.

So today, after loading horse manure, with wood shavings bedding, into my truck pitchforkful by pitchforkful, I drove home and unloaded everything pitchforkful by pitchforkful into my compost bins. Each bin got a lot more than a restricted diet of just the horse manure mix, though. I alternated layers of manure with mowings scythed from my small hayfield, wetting down each layer well and sprinkling occasional layers with soil, for bulk, and ground limestone, to counteract soil acidity.
Compost bins
Manure is not a necessity for good compost. The manure mostly is for nitrogen, one of the two main foods of compost microorganisms. Some of my piles get that nitrogen from soybean meal, an animal feed usually meant for creatures that you don’t need a microscope to see. Early in the season, young grasses and weeds, which are high in nitrogen, do the same. And truth be told, any pile of plant material, if left long enough, will turn to compost. The nitrogen helps the material chug along faster on its way to compost, and the faster the microbes work, the hotter it gets.

Winter Work for Microbes

I’ll be feeding my last compost pile of the season all winter long. Just a little at a time, mostly scraps and vegetable trimmings from the kitchen with occasional toppings of leftover hay. Adding stuff slowly to a compost pile doesn’t let enough critical mass build up for heat, and especially not in winter’s cold.
Dog and chickens on compost pile
No matter. I just let piles that don’t heat up sit longer before I use them. It’s the combination of time and temperature that does in all the bad guys that hitchhike into my compost piles. So 1 hour at 140° F. might have the same deadly effect as a week at 115° F. My hot piles sit for a year before I use them; the cold piles cook longer. It ain’t over ‘til it’s over.

TASTING AND TIDYING, OR NOT

Fruit Heaven

Hudson's Golden Gem apple

Hudson’s Golden Gem apple

I remember a few years ago of having a most fruitful — and I mean this very literally — experience visiting one of the USDA’s germplasm repositories. “Germplasm repository” doesn’t sound like the kind of place anyone would want to be, but these USDA repositories are, in fact, sunny, colorful places, often redolent with enticing aromas. In the case of the one I visited, the aroma was of ripening apples.

Germplasm is the stuff that gives rise to an organism, and the USDA has set up repositories around the country to house various kinds of plants. Each repository is situated where a particular group of plants grows well. So Davis, California is home to the repository for figs, pomegranates, and Asian persimmons; Corvallis, Oregon is the repository for pears, gooseberries, and mint; and Geneva, New York, where I visited, houses the collections of apples and American-type grapes. (My own gooseberry collection helped build the gooseberry collection at Corvallis about 30 years ago.)

Taking into account seed collections and other, related work, these repositories maintain over 20,000 accessions of plants representing over 300 species. Germplasm from these collections is available to scientist and other interested citizens, which is how I obtained grafting wood to make most of the rare varieties of apples and pears that I grow.

So there I was — a fruitophile — standing with clipboard in hand and camera in pocket in in a field of apple trees, each one a different variety. My mission: Photograph and collect 3 to 4 samples of a couple of dozen varieties. What sweet labor! (I had previously contacted the repository staff and received permission).

Up and down the rows I went, photographing, collecting, and, of course, tasting. Apples have been cultivated for so long and are so popular a fruit that it’s no wonder that such great variation exists in the fruits’ appearances and flavors. Flavors include anise-flavored Ellison’s Orange, sweet Mollie’s Delicious, spicy-tart Cox’s Orange Pippin, and everything in between and beyond. The range in color goes from gray-brown Pomme Grise to cheery red-splashed yellow King of the Pippin. And then there are variations in fruit size and shape and, less obvious, characteristics such as pest resistance, productivity, and cold tolerance.

Ashmead's Kernel apple

Most important, to me, is flavor. I should have brought a palate cleanser because after a while all the varieties were beginning to taste like . . . well . . . apples. Nonetheless, two varieties that I did not grow did stand out for flavor; I ordered grafting wood of Hudson’s Golden Gem and Pitmaston Pineapple to graft onto trunks of my Ingrid Marie trees once I lop their tops off.

After the apples, there were grapes to photograph and sample.

Tidy Not

Boy, would I love to tidy things up with some pruning now. The Golden Celebration rose bush would look nicer in coming months with those couple of tall, gawky stems cut off or back.
Golden Celebration rose
Grape and hardy kiwi stems are reaching out all over the place, grabbing onto each other and anything else they can wrap around.
Kiwi vines
The pear trees have a nice spreading form — except for watersprouts shooting vigorously skyward from the uppersides of some of the spreading branches. How nice it would be to cut these plants back now rather than in spring.

But I’m going to restrain myself from doing any pruning. As stated in The Pruning Book (by me!), “Although immediate regrowth rarely occurs after late summer or autumn pruning, cells right at the cut are stirred into activity to close off the wound. Active cells are liable to be injured by cold weather, which is a reason to avoid pruning in late summer or autumn except in climates with mild winters or with plants that are very hardy to cold.”

Gooseberries and currants are super cold hardy plants and begin growth relatively early in spring. All of which makes a good case for pruning those plants now.

And a Case for Not Tidying

Rather than prune, a good place to re-channel that “tidy everything up” urge is in the vegetable and flower garden.

Cleaning up is one way to lessen pest problems next year. As I pulled out spent bush bean plants, I gingerly placed them into the garden cart and, from there, onto the compost pile, trying not to disturb the resident bean beetles. Those bean beetles had hoped to spend the winter on site, to emerge next spring and lay eggs on next year’s bean plants. I’m hoping to “cook” as many of them as possible in the compost pile.

Tomato plants are looking a bit ragged even though they’re still bearing some tomatoes for fresh eating. Gathering up all stems, leaves, and old fruits and composting them reduces the inoculum load of diseases such as early blight and septoria leaf spot. Left in place, they would spend winter out in the garden ready to infect next year’s plants. It’s not a question of eradication, which isn’t possible, but of balance.
Tidy vegetable garden beds
Cutting down old peony stems and composting them takes inoculum for next years botrytis disease off-site. Left to infect plants next spring, botrytis could keep peony flower buds from unraveling.

As Charles Dudley Warner wrote over a hundred years ago (in My Summer in the Garden, which I highly recommend and is much more than a gardening book), “the closing scenes are not necessarily funereal . . . a garden . . . goes into winter-quarters . . . neat and trim . . . so that its last days shall not present a scene of melancholy ruin and decay.”

Battle for Figs: Victory

Some History

I don’t know the score over the years, but this year’s victory is mine. The battles have been with scale insects, both armored scales and their cousins, mealybugs (but rarely both in the same year), on my greenhouse fig plants.
Eating a fig
Those fig plants are planted in the ground in a minimally heated greenhouse, where winter temperatures can sink to about 35°F. The oldest of these plants have trunks 8 inches in diameter. They thrived for years without any pest problems, scale of otherwise. A few years ago, the insects made their appearance, sometimes ruining almost the whole crop.
Mealybug
Over the years I fought them in various ways. One year it was spraying the dormant plants with alcohol. Another year it was, more aggressively, scrubbing trunks and stems of dormant plants with a toothbrush dipped in alcohol. Ants herd and protect scale insects, so another year I fenced the ants off the plants with a band of masking tape coated with forever (almost) sticky Tangletrap around the trunk of each plant.

An expensive but short-lived success was the two releases of the predatory ladybird beetle Cryptolaemus montrouzieri and the parasitoid wasp Anagyrus pseudococci.

Mealybug destroyer

These biocontrol helpers ended up valuing each fig at about a dollar, still worth it. I screened all openings in the greenhouse, hoping to perennialize them inside. (It was not effective.)

Battle Plan, Done

So this year I tried a multipronged approach.

The biggest change was, rather than growing the figs as bushy trees, training them as espaliers. Espalier is the training of plants to an orderly, usually two-dimensional form both for beauty and, in the case of fruit plants, for good production of high quality fruit. For my figs, an additional benefit would be that each plant would only have one point of contact — its trunk — with the ground. IA band of masking tape coated with Tangletrap would be a roadblock on the ant highway. (Plus the look of the plants always elicits a “Wow” from visitors.)
Rabbi Samuel fig, espaliered in greenhouse
The fig plant growing near the greenhouse endwall has a short trunk that, after rising to about 18 inches from ground level, bifurcates into two, self-supporting horizontal arms extending parallel to the wall in opposite directions. At the head of each of the south beds, a fig tree is planted each of whose trunk is terminated by just a single, self-supporting, horizontal arm reaching down the bed to the sidewall. With just a trunk and one or two arms, thoroughly scrubbing down the dormant plant with alcohol is a relatively quick job. Quick enough to prevent 2 or 3 scrubbing before plants resume growth in early spring from becoming tedious.

Another nice feature of this training system is that pruning the plants at the end of the season is a no-brainer. Vertical shoots that rise up from the horizontal arms are thinned to keep neighboring shoots 8 inches apart and helped along in their vertical growth by being trained to pieces of bamboo attached to the greenhouse roof. (Yes, an ant could walk up the wall and across the roof of the greenhouse and then down the bamboo to get at the plants but they are either not that smart or energetic; it hasn’t happened.)
San Piero fig
A little later in the early part of the greenhouse growing season I gave the plants some dowsings with neem oil. I’m not sure how effective the neem component is but “horticultural oil” itself is effective in fighting off scale insects.

A ring of cinnamon around the base of each plant provided further disincentive to the ants, who will not cross a cinnamon line. The cinnamon and the Tangletrap did need renewal once per season.

As new fig shoots soared skyward near the greenhouse roof, I used a pole pruner to prune out the top of the growing shoot. Side branches, of course, then grew, and I periodically had to to hack them back also.

Uh Oh, But All Still Good

Everything was copacetic and we were harvesting figs, which formed along the vertical stems at the juncture of almost every leaf. Then, in late August I noticed some mealybugs on one plant. Time for Cryptolaemus montrouzieri again. I released them in early September and we were back in business, harvesting large handfuls of three different varieties of delciously sweet figs — San Piero, Brown Turkey, and Rabbi Samuel — daily.

And then, just today, I noticed armored scales on the plants, and a few ants! I’m not sure how the ants are getting onto the plants, but one possible “benefit” of the armored scales is hardly any mealybugs. Perhaps they can’t coexist.
Fig scale
All the measures I took against mealybugs should also be effective against the armored scales, except for the Cryptolaemus montrouzieri. Their predator Aphytis melinus, also known as the Golden Chalcid, has been effective against armored scales.

I’m not taking action. With less sunlight and cooler temperatures the figs trees have slowed down, running out of new stems on which to hang fruit. No matter; it’s been a good season of fresh figs.

TWENTY-TWENTY FORESIGHT

North Vegetable Garden

I’m stepping outside this sunny afternoon for a walk around the farmden, pad and pen in hand to evaluate some of this season’s goings on to make notes for next season. Not that the season is anywhere near over yet. I expect to be out and about with pitchfork, harvest basket, and garden cart at least into December. But no surprises are expected at this point.

Starting in the north vegetable garden: tomatoes. Over the years I’ve honed the number of varieties here from too many to our half-dozen or so favorites.

Valencia tomato

Valencia tomato

The goal is top-notch flavor and reasonable productivity. San Marzano, which is very productive, might taste like cotton fresh but it’s a must for the best-tasting cooked tomatoes. The San Marzanos get their dedicated canning jars, but also good canned is Blue Beech and, great for fresh eating also, are Amish Paste and Anna Russian.

Three more, mostly for fresh eating next year, are Paul Robeson, Belgian Giant, and Valencia. Valencia has year after year proven to be a very good, very beautiful, and productive tomato. Pretty also, round, smooth, and pale orange. Cherokee Purple hardly produced this year, and hasn’t in years past, so it’s scrapped from the list for next year.

I consider Sungold to be the best-tasting cherry tomato, and it’s still bearing a daily abundance of persimmon-orange fruits. I put in 8 plants; next year, I’ll plant a few more.

That makes a total of only seven tomato varieties — unless someone twists my arm into trying any other variety.

I’ll try for a repeat abundance of peppers next year by again growing Carmen and Sweet Italia.

Italian Sweet peppers

Sweet Italia peppers

Sweet Italia tastes better but Carmen bears a little better, especially now. The non-hot hot pepper Habenada, is billed as having hot pepper flavor minus the hotness. More like no hotness and no flavor, a no-go for next year.

South Vegetable Garden

Walking over to the “south garden,” the highlights this year were cauliflower, beans, and squash. Cauliflower is allegedly a challenge to grow. I don’t like it so grew it just for the challenge, and because Deb likes it. I was successful, and she can eat it all.

Blue Lake and Kentucky Wonder pole beans keep pumping tender new beans, as pole beans are wont to do. Or is it Blue Lake and Romano? Or Kentucky Wonder and Romano? The row label is buried deep in a wall of foliage so I won’t know until the end of the season. Pole beansI guess two plants per pole, with poles about a foot apart, is too crowded. Next year: one plant per pole.

Pole beans begin bearing late so I also grow bush beans (bush Blue Lake and bush Romano), which peter out after a couple of weeks but yield an early crop for the freezer. I usually put in a second planting also, which is — note for next year — not needed. We didn’t have to harvest any of them because the pole beans kicked in soon enough.

It’s been a banner year for winter squash. I usually plant squash out in the meadow in the cleared strip of land between the dwarf apple trees. And usually, deer or my poultry eat the vines or the fruit so the harvest is usually nil. This year I planted squash in the rich soil along and inside the back fence of the south garden, which backs up to the poultry run. The squash climbed up and over the fence and onto the fenced roof of the run; now there’s plenty to harvest, perhaps too many!Winter squash on poultry run

South Vegetable Garden

Two flowers were standouts this year: On a whim I purchased red buckwheat seed from Baker’s Creek (www.rareseeds.com). With no place special in mind about where to plant it, I ended up sprinkling the seed in a bed just outside the north vegetable garden.
Red buckwheat
For the past couple of months it’s been a 4-foot high cloud of pale red beauty, which, along with how easy it is to grow, earns it a place in next year’s garden. But where?

One other flower stood out also, delphinium. Not a five foot spire of pale blue — I also have them, the Pacific Giant hybrids — but a spire less than two feet tall with dark blue flowers.
Delphinium, Blue Mirror
It’s Blue Mirror Chinese delphinium (www.reneesgarden.com) and it surprised me by blooming its first year from seed. Let’s see how perennial this perennial turns out to be. Around here, its giant cousins typically die out after a  couple of years.

All in all, it’s been an excellent growing season. Spring frost hazard was minor for tree fruits. Rainfall and sunshine were balanced well. Pest problems were minor. Pears are still challenging to harvest at just the right moment so that they can ripen indoors to that delectable window between underripe grassy and overripe sleepy. I did get Concorde at the right moment this year. The ripe fruits are delectable, combining some of the smooth buttery sweetness of Magness pear along with a dash of vanilla.

SOME THINGS FOR SOME SENSES

Visual Delight, and some Aroma

I once grew a rose, Bibi Maizoon, that I considered to be as close to perfection as any rose could be. Its blooms, that is. They were cup-shaped and filled with loosely defined row upon row of pastel pink petals, nothing like the pointed, stiff blossoms of hybrid tea roses. Completing the old-fashioned feel of Bibi Maizoon blossoms is the flowers’ strong, fruity fragrance.
Bibi Maizoon rose
(In case you don’t know who Bibi Maizoon was, she was a member of the royal family of Oman. The Bibi Maizoon rose was bred by British rose breeder David Austin.)

The bush itself was as imperfect as the blossom were perfect. Where to begin? For starters, the thin stems could hardly support the corpulent blossoms. Couldn’t, in fact, so the blossoms usually dangle upside down. Upside down blossoms were not that bad because I considered Bibi best when cut for vases indoors to better appreciate her rare appearances and fragrance.

Top those deficiencies with the fact that Bibi Maizoon was also only borderline cold hardy in my garden and you would rightly guess that I no longer grow this rose.

I haven’t abandoned David Austin roses. I generally like them for their old-fashioned look: the bushes are, well, bushy and full; the blossoms have softer colors than those of traffic-stopping hybrid tea roses; and they are disease resistan and strong-growing.

I’ve previously praised the variety L. D. Braithwaite for its almost nonstop, dark red blossoms, red tinted leaves, and ability to laugh off any amount of cold. Three other varieties — Golden Celebration, Lady of Shallot, and Dame Judi Dench — came into my garden in the last year, their blossoms with varying degrees of yellow, the first a pure golden yellow, the second apricot-yellow, and the third apricot orange. Delicious. They all seem, so far, near-perfect.

Organoleptic Delight, and also Beautiful

Ellison’s Orange is as unknown to most people as is Bibi Maizoon. It’s an apple, an old and very delicious apple, and, oddly enough, ripening right now. Everywhere else I read that this apple is supposed to ripen later in September and on into October, yet every year my Ellison’s Orange fruits ripen about this time of year.

Like Bibi Maizoon, Ellison’s Orange has its good and bad sides. On the plus side, it bears very well and at a young age. It also seems to be somewhat resistant to scab and cedar apple rust diseases, contradicting other sources on this point also. And what a beauty the fruit is, with its orange blush over a yellow background.

For me, the downside of this variety is the absolute necessity to pick it at just the right moment. One day an apple seems puckery underripe; the next day it might be sleepy and soft. If I harvest very carefully, I catch an apple at its delectable best, which is sprightly with an intense flavor that hints of anise seed.
Ellison's Orange apple
I made my tree from a piece of stem whose cells trace back over a hundred years, to the garden of a Reverend Ellison in Lincolnshire in the east of England. The parents of the reverend’s new apple weren’t lightweights. One parent, Cox’s Orange Pippin, the king of British apples, has an intense flavor that sometimes hints of anise seed. The other parent, Calville Blanc, an old French apple popular in the court of King Louis XIII, has a spicy flavor with just a hint of banana. No wonder Ellison’s Orange tastes so good – as long as I catch it at the right moment.

Another Tasty Delight

If you buy corn at a farmstand or market these days, no need to have boiling water ready, as gardeners did in the past to stop enzymes from starting the conversion of kernels from sugary sweet to starchy bland. Two genes incorporated into modern corn varieties dramatically slow this flavor decline. They also ratchet up the sugars, making modern corns supersweet to begin with.

Call me old-fashioned, but my favorite variety of sweet corn, the only variety that I grow, is the old variety Golden Bantam, which lacks those modern corn genes. Although not nearly as sweet as modern hybrids, Golden Bantam has a very rich corny flavor with – to some tastes — just the right amount of sweetness.

 Golden Bantam, a hit since 1906

Golden Bantam, a hit since 1906

Golden Bantam was introduced into the seed trade in 1902 by W. Atlee Burpee Company, who got their original 2 quarts of seed from New York farmer William Coy, who had tasted and enjoyed eating some ears at his cousin’s house in Massachusetts. Long story short: Everyone fell in love with Golden Bantam and it became the most popular corn of its day. An article in The Boston Transcript of 1926 states that “In the twenty-four years since [1902] it has made more friends than anyone else could make outside the movies. Which proves that popularity does sometimes follow real merit.” It’s an odd way to compliment but you get the picture.

Golden Bantam pre-dates hybrid varieties, the latter of which, in addition to other characteristics, ripen very uniformly. In a backyard garden, a whole bed of corn ripening at once isn’t necessarily a plus. I want to eat some corn every day, with a little extra each day for freezing.
Corn hills
My four beds of corn, the first planted in mid-May (around the date of our last-killing frost of spring)  and the subsequent beds staggered every two weeks, provides just that. We’ve eaten corn almost every day since each mid-August and Golden Bantam shows no signs of slowing down or boring us.

Mmmmmmmm

Genetics, Timely Harvest, and ?

As I led my nephew Jeff, his wife, and their two kids around the garden a couple of days ago, I plucked fruits and vegetables here and there for them to sample. They could compare them with what New York City, where they live, has to offer. They were blown away by the flavors here.
Delectable fruits & vegetables
Okay, I cheated a little. They got to sample some of the best of the best: figs so soft they were drooping from their stems, white alpine strawberries, Sungold cherry tomatoes, Golden Bantam sweet corn, and Kentucky Wonder green beans, all picked on the spot and at their peak of perfection. The Golden Bantam corn, you won’t find that offered for sale pretty much anywhere these days although it was the standard of excellence in sweet corn 100 years ago. The white alpine strawberries (Pineapple Crush) are too small and too soft for anyone to market commercially.

But genetics isn’t the whole story. Timely harvest is as important. Commercial considerations aside, it takes a certain skill to know just the right moment to do the deed.

With some plants, especially vegetables, timely harvest is easy. You pick such vegetables as lettuce, beans, and okra as soon as they’re big enough to suit you. You pick tomatoes when they’re red, which is also when I pick sweet peppers; red peppers taste quite different and, to me, a lot better than green peppers.

I haven’t grown eggplants that much over the years. This year they are particularly abundant and I’m still learning how to pick them. Full size? Glossy?

Sweet corn can also be tricky. It took me a few years to get the knack of picking it at its best. I first look for dried up silks and then, taking a tip the vegetable extension specialist at the University of Wisconsin passed on to me many years ago, I wrap my fingers around the ear and feel for fullness. That’s when it’s time to snap the ear down and off the stalk. Gauging that fulness does take practice.

Test for Ripeness

Fruits are a little trickier than vegetables, especially some fruits. Easiest of all are raspberries and blackberries. Tickle the clusters and let the truly ripe ones drop off, as they are wont to do, into the palm of your hand. Too many people tug at blackberries to get them off the plants; flavor suffers. Blueberries are similar to blackberries in that color doesn’t tell of full ripeness; the tickling method does.
Black raspberry fruit
I grow a number of varieties of two vining fruits: grapes, of course, and hardy kiwifruits. The kiwifruits, which will begin ripening in a couple of weeks, retain their fresh, green color right through ripeness. What they do do when ripe is to soften. But not all together. Fortunately, when sufficiently mature on the plant, these fruits can finish ripening after harvest. As soon as the first kiwis ripen, I pick them all. They ripen to perfection in a few days at room temperature, longer under refrigeration.
Hardy kiwifruit
Blue or red grapes seem ripe when they turn their final color. Ripe for commercial purposes perhaps, but not perfectly so. When truly ripe the whole bunch will snap easily from the cane to which it is attached. I sometimes leave the bunches (the ones I enclosed in paper bags in early summer) even longer and, to a point, their flavor just gets better and better.
Edelweiss grape
Most fruits, in fact, taste best if harvested when ready to part with the plant. That’s why for fresh eating, not storage, I sometimes harvest my apples from the ground, daily, the morning they drop. This might not be the best method for all varieties but makes for the very best Macoun apples.
Hudson Golden Gem apple
Generally, with tree fruits, I look for a change in color, especially background color, before considering harvesting a fruit. If there’s any green, I let it be. If color tells me that a fruit is potentially ready to be picked, I cup the fruit in hand, then lift and twist. If ripe, the fruit stalk readily separates from the plant. If that doesn’t happen, the fruit needs more time on the plant.

Tricky, for Me at Least

Two fruits whose harvest moment I’m still honing are watermelon and European pears.

I’ve tried all the methods with watermelon: thumping for a sound not too hollow and not to dull (the sound of knocking your knuckles against your chest as opposed to your forehead or stomach); a dried tendril opposite the fruit; a yellow-bellied fruit. They’re all guides but none are the end-all to timely harvest. I never had that problem with my large watermelon crop from my garden in southern Delaware.

Magness pear

European pears ripen from the inside out so become mush if left on the plant to thoroughly ripen. They need to be harvested mature but not yet ripe as indicated by some fruits dropping, a slight change in skin color, and readiness of the fruit stem to part from the branch. Fruits brought indoors to finish ripening are ready to eat when the flesh at the stem end gives with slight finger pressure.

Still, it takes a certain je ne sais quoi. And again, I’m adept at timely harvest of those varieties I’ve grown the longest and of which I have the most.

Climacterics

One reason pears and kiwifruits can ripen to perfection after harvest is because they are climacteric fruits, which undergo a burst of respiration and ethylene (a plant hormone) production as ripening begins. Some of these fruits, which also which include banana, apple, tomato, and avocado can, if sufficiently mature, ripen following harvest. Soon after their climacteric peak, these fruits start their decline.

Citrus, fig, strawberry, plum, and raspberry are examples of non-climacteric fruits, whose ripening proceeds more calmly. Non-climacteric fruits will not ripen at all after they’ve been harvested. They might soften and sweeten as complex carbohydrates break down into simple sugars, but such changes are indicative of incipient rot rather than ripening or flavor enhancement.

For more about flavor, ripening, and climacteric, see my latest book The Ever Curious Gardener: Using a Little Natural Science for a Much Better Garden.

Midsummer “To Do” List

Maintenance, Pruning

For many gardeners, spring is the critical gardening season, what with preparing the soil, starting seedlings, setting out transplants, pruning, watching and staying prepared for late frosts and . . .  In my view, right now is just as crucial, and for an equal number of reasons.

True, a 90 degree day with high humidity doesn’t exactly pull you out to the garden to putter around in blazing sunlight. But early mornings around here are mostly cool, calm, and beautiful.

Much of what needs to be done is regular maintenance. Pruning tomatoes, for instance.Tomatoes, staked, July I train my tomato plants to stakes and single stems, which allows me to set plants only 18 inches apart and harvest lots of fruit by utilizing the third dimension: up. At least weekly, I snap (if early morning, when shoots are turgid) or prune (later in the day, when shoots are flaccid) off all suckers and tie the main stems to their metal conduit supports.

Espalier is the training of trees to two dimensions whereby the tracery of the stems is as decorative a plant feature as are the leaves, flowers, and/or fruits. To maintain that tracery of branches, my espaliered Asian pears need frequent pruning. Espalier Asian pearI lop wayward shoots either right back to their origin or, in hope of their forming “spurs” on which will hang future fruits, back to the whorl of leaves near the bases of the shoots.

The response of the pear trees depends on the weather, which is unpredictable. Dry sunny weather is conducive to spurs. Rainy weather coaxes, instead, new shoots pop out right where I cut back old shoots. I think.

Maintenance, Water

Whether or not the weather is dry, rampant growing plants quickly suck the soil dry. So I also keep attentive to watering this time of year. The vegetable garden and potted plants are the neediest in this respect; fortunately, they demand little from me to do because a timer turns its drip irrigation system on and off automatically. All I have to do is to periodically check to make sure drippers are all dripping. Drip tubes to potted plantsNewly planted trees and shrubs are another story. This first year, while their roots are spreading out in the ground, is critical for them. I make a list of these plants each spring and then water them weekly by hand all summer long unless the skies do the job for me (as measured in a rain gauge because what seems like a heavy rainfall often has dropped surprisingly little water).

A one-inch depth of water is needed to wet a soil about a half a foot deep. I provide this with 3/4 gallon of water per estimated square foot spread of the roots.

Fall preps

Sowing seeds and setting out transplants isn’t only a spring gardening activity. Tomatoes, peppers, eggplants, cucumbers, and other summer vegetables peter out during the shorter, cooler days of late summer and early fall. But there are plenty of vegetables that enjoy growing conditions that time of year.

Some of the fall vegetables need to be sown now to be large enough to mature in fall. No need to provide space for them by digging out tomatoes, peppers, or any other summer vegetables. I sow endive, kale, lettuce, Chinese cabbage, and, if I could stomach it, cauliflower seeds in midsummer in seed flats. Once they sprout I “prick them out” into individual cells of automatic watering GrowEase trays for later transplanting. Autumn seedlingsNot only vegetables get this treatment. Buy a packet of seeds of delphinium, pinks, or some other perennial, sow them now, overwinter them in a cool place with good light, or a cold (but not too cold) place with very little light, and the result is enough plants for a sweeping field of blue or pink next year. Sown in the spring, they won’t bloom until their second season even though they’ll need lots of space that whole first season.

Cuttings are another way to propagate plants this time of year. Early this morning, when cells were plump with water, I made cuttings of hardy kiwifruit and begonia.

And, Yes, Weeds

Weeds can make all this pruning, watering, and seeding for naught. Clear ground is needed in which to eventually set my cabbage and kale transplants. Weeds stealing water and nutrients, even sunlight, won’t let plants grow at their best. They’ll also promote disease by preventing free flow of air; fungi fester under damp conditions. Weedless corn & lettuce bedEvery time I look at a weed, I’m thinking how it’s either sending roots further afield underground or is flowering (or will flower) to scatter its seed. Much of gardening isn’t about the here and now, so I also weed now for less weeds next season. It’s worth it.
