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.

Pests Pesky and Not So

Memories

The tumbled over Red Russian kale seedling brought back old memories. It was like seeing the work of an old friend — or, rather, an old enemy. It’s been so long since I’ve seen a cutworm at work in my garden that I couldn’t even get angry at it.

Cutworm and friend's broccoli

Cutworm and friend’s broccoli

I scratched around at the base of the plant to try and find the bugger. Too late, fortunately for him or her because its fate would then have been a two-finger crush. The cutworm in a friend’s garden I visited last spring was not so lucky.

The bad thing about cutworms are that they chop down young, tender seedlings. At that age, seedlings’ roots lack the energy to grow new leaves; the plants die. (I wonder how the cutworm benefits from lopping back the seedling; the felled plant usually doesn’t get eaten.)

Cutworm damage

My kale plant

The good thing about cutworms is that, in my experience, they are few and far between — just one or two every few years.

Also, on a garden scale, they’re easy to control, if needed. They prepare for their meal by wrapping their bodies around the plant stems. When I feared them more, I would cut cardboard rolls at the center of paper towels or toilet tissue into lengths of about 1-1/2 inches long, slit one site, fit it around the seedling, press it into the ground, and tape it back closed. A bit tedious, I must admit.

Then I read that cutworms can be fooled. They only attack soft, young seedlings. A thin stick or toothpick slid partway into the ground next to a seedling makes a cutworm think the plant is a woody plant and, hence, out of its league. Since I didn’t find the culprit in my garden, I slid thin sticks next to nearby seedlings. For my friend’s garden, I returned from her kitchen with a handful of toothpicks and instructed her teenage son what to do with them.
Cutworm protection with stick
Except for today, I haven’t taken precautionary measures against cutworms for many years. Especially every morning, robins, catbirds, and mourning doves are pecking around the ground in my garden; I suspect that’s one explanation for the lack of cutworms.

A Good Parasite

A week or so ago, I saw another old “friend” in the vegetable garden. I noticed that leaflets had been thoroughly stripped from one region of one tomato plant. Obviously, a tomato hornworm, a voracious and rapid diner, was lurking somewhere amongst the existing foliage. A cause for panic? No!

The culprit, a green, velvety caterpillar with widely spaced, thin white stripes and some rows of black dots, is undoubtedly intimidating.
Tomato hornworm
Besides its voracious appetite — you can hear it chomping away — it is the size of an adult pinky.

Still, not to worry. Like cutworms, tomato hornworms turn up in my garden only every few years. And again, like hornworms, they seem to arrive, or show evidence, solo.

I did not reach out to crush the hornworm when I saw her because her back was riddled with what looked like grains of white rice standing on end. Those “rice kernels” are actually the eggs of a parasite that in short order turns that beautiful body to an ugly mush. It’s a dog eat dog world out there.

A Call for Action with This One

I can’t be so complacent about all pests that can turn up in my vegetable garden. Probably the worst one that causes problems every year is one or more of the caterpillars now, as I write, chewing away on the leaves of cabbage and its kin. The symptoms are quite evident: holy . . .  whoops, holey . . . leaves upon which is deposited dark green caterpillar poop.
Cabbageworm damageA close eye is needed on cabbage and its kin because one day there’ll be no damage and next time you look, leaves are riddled with holes and poop.

And then, action is necessary. Hand-picking is one option. I choose to use the biological insecticide B.t., short for Bacillus thurengiensis and commonly sold under such names a Dipel or Thuricide. It should be used with restraint because the insects can — and, in some cases, have — developed resistance to this useful pesticide which is very specific in what it harms and what it leaves alone.

Now that I mention it, excuse me for 10 minutes while I mix up a batch of spray for my cabbages, Brussels sprouts, and kale plants . . .

I’m back. The caterpillars seem to prefer cabbage, Brussels sprouts, and cauliflower over kale, which is fine with me because kale is my favorite of the lot.

Many predators, including certain wasps and beetles, diseases, birds, and bats, keep these caterpillar pests under control. Evidently not enough, though, in my garden.

Waste Not, Want Not

Two Reasons to Compost

With weeding, harvesting, watering, swimming, kayaking, golf, and biking to do this time of year (not that I do all these), why would anyone spend time making compost? For one or both of two reasons, that’s why.

First, as an environmentally sound way to get rid of so-called “garbage.” Landfilled, the valuable nutrients and organic matter locked up within old broccoli stalks, rotten tomatoes, even old cotton clothes are taken out of our planet’s nutrient cycle almost forever. Landfilling, to me, also disrespects the soil, that thin skin over the Earth that supports much of life here.

Once Levi's, now almost compost

Once Levi’s, now almost compost

This leads to the second reason to make compost now. I require plenty of compost for my gardens so need to scrounge every bit of waste organic material as it becomes available. Even go out of my way to haul it in. Or create it.

Sustainabilityness

Having oodles of compost goes a long way to make a garden or farm truly sustainable. Even though relatively low in nitrogen, as far as plant needs, compost can do away with the need for any other fertilizer.
Compost bins
For years, just to make sure that my compost-fed plants were not going hungry — for nitrogen — I spread soybean meal on the ground just before laying down the compost. 

Soybean meal provides an organic form of nitrogen but is hardly a sustainable way to nourish the soil. That meal comes from soybeans grown on fields who-knows-where, fed with fertilizers needing fossil fuels for their production, tilled by fossil-fueled tractors, processed in fossil-fueled factories, and transported by fossil-fueled trucks. The same could more or less be said for any fertilizer, organic or otherwise, except compost.

Years ago I made a computation, based on an estimate of how fast nitrogen is released from compost and average nitrogen needs of vegetable plants, of the amount of compost needed to provide all the nourishment a garden would need for one growing season. The amount is about one cubic yard per 300 square feet or, (if you’re a farmer, you should be sitting down), about 70 tons per acre. But these figures are for planted areas, so compost need be applied to only the planting beds.

Also, compost has a residual effect, with only a portion of nutrients being released each year. Yearly additions build soil fertility and nourish a healthy soil life.
Spreading compost
On my farmden, a one inch depth of compost provides all the nourishment needed for intensively grown, healthy and healthful crops for an entire season. I just lay the stuff on top of the ground to get the most out of it nutritionally and biologically, and provide a weed-quelling mulch and seedbed.

Self-Analysis

Is making compost truly a way to sustainably nourish the ground? As with so much of agriculture, a balance is sought. Let’s check what goes into my compost piles.

The usual, of course: carrot peelings watermelon rinds, egg shells, old bread, and other fungal and bacterial treats from the kitchen compost bucket; cabbage stalks, old lettuce, and weeds (all even if pest-ridden, diseased, or otherwise) from the garden. I also throw in old cotton or wool clothing, even leather shoes and gloves. Because of noncompostable components such as elastic bands and synthetic cloth parts, they all yield very interesting products staring out in the finished compost.Composted shoeOccasional, light sprinklings of soil add bulk to the finished mix. Occasional, sprinklings of ground limestone keep planted ground, final stop for the compost, in the right pH range.

Two feedstuffs make up the bulk of the compost. One is horse manure, the most questionably sustainable part of the whole mix. The horse manure is an abundant waste product of a nearby horse farm.

Adding hay to compost

Fashionable

The other feedstuff is hay that I scythe from a one acre field here on the farmden. In mowing hay and composting it, then using the compost to feed my gardens, I am, it seems, “robbing Peter to pay Paul.” But given time, soils regenerate nutrients on their own so I try to rotate which portions of the field I scythe.

Not for You? Then . . .

Making compost isn’t, for reasons of time, space, and inclination, for everyone. In some regions, you can deposit your compostables at a recycling center for composting. And an increasing number of companies are popping up that, for a fee, will pick up your organic waste for recycling. Check web listings for town and county offerings.

I like to make compost, finding it interesting, useful, even enjoyable. And my plants love it.

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.

Uh Oh, Watch Out for This One!

Past pests

Spotted lanternfly

Watch out for this one!

Over many years of gardening at the same location, I’ve seen pests come and go. And if they didn’t actually leave, they at least didn’t live up to the most feared expectations.A few years ago, for instance, late blight disease ravaged tomato plants up and down the east coast. The disease overwinters in the South and normally hitchhikes up north if temperatures are cool, humidity is high, and winds blow in just the right direction. That year it got a free ride here on plants sold in “big box” stores. I no longer consider late blight any more of a problem than it was before that high alert summer.

A few years ago, I was ready to say goodbye to my lily plants when I first heard of and then saw red lily beetles crawling and eating their way across my lilies’ leaves. Red lily beetleThey’ve been making headway across the Northeast since arriving in Cambridge, Massachusetts in 1992. But my lilies still look fine and, yes, I do still see some of those beetles. Perhaps one of the natural predators released in Rhode Island years ago has joined the crowd here, minimizing damage.

Japanese beetles were never a problem here until around 2006. I tried handpicking and trapping but their numbers — and damage — continued on the upswing. Japanese beetlesThen, about 10 years later, and since then, they’ve showed up on schedule, which is now, but then disappeared for the rest of the season. Did they go off to greener pastures? Did they succumb to soil nematodes or fungi?

And the spotted swing drosophila, which really went over the line by attacking my favorite fruit, blueberries. Spotted-wing_DrosophilaAlthough chemical, mechanical, and biological controls are still under development, this pest has not put an end to my blueberry-eating days. Thanks to some bait and kill traps developed by Cornell’s Peter Jentsch, damage has been kept to a minimum.

The list goes on: marmorated stinkbug, leek moth, emerald ash borer, hemlock woolly adelgid . . . 

Most Frightening of All!?

A new, most frightening pest is now lurking offstage. The spotted lanterfly (Lycorma deliculata, and heretofore to be abbreviated SLF) is an invasive leafhopper native to China, India, and Vietnam. It feeds on just about everything, including various hardwoods as well as grapes and fruit trees.Spotted Lanternfly adult lateral view To make matters worse, it also exudes a sticky honeydew which falls on any nearby surface (other leaves, lawn furniture, etc.) and, worse yet, becomes food for a fungus than turns that stickiness dark.

This voracious pest can spread quickly; within 3 years of finding its a way into South Korea, it had spread throughout the country, about the size of Pennsylvania. And now SLF has arrived in Pennsylvania (well, actually, a few yers ago)!

In autumn, the lanternfly lays its eggs, which get a mud-like covering, on any hard surface, be it the bark of a tree, a rock, even a car bumper. SLF egg massIn spring, nymphs hatch and climb trees in search of soft, new growth. The one-inch long adults emerge around now; they’re very mobile, usually jumping but also capable of flying, which is when their spread wings display their bright red color. With wings folded, the insects are mostly gray wings with dark spots.SLF life cycleA few natural predators, such as spiders and praying mantises, feast on SLF, but not enough. What to do? There are a few approaches.

A favorite host is tree-of-heaven, a weed tree that is not a favorite of most humans. Getting rid of these trees, then, is one way to limit spread of SLF. Problem is that a single female tree might produce 300,000 seeds per year; and the trees are hard to kill, resprouting and growing quickly from root sprouts.

Systemic pesticides injected into the trees would kill any insects feeding on them. Someone recounted to me of seeing a six-inch depth of dead SLF beneath infested, pesticide treated trees!

One thing you and I can do when leaving any area known to harbor SLF is to check what we’re taking with us, on the car bumper, for instance. Currently, certain southeastern counties of Pennsylvania are under quarantine, which means that movement of certain articles (such as brush, debris, or yard waste, landscaping or construction waste, logs, stumps, firewood, nursery stock, outdoor recreational vehicles, tractors, tile, and stone) is restricted out of these areas. Although established populations have not been reported elsewhere, individual insects have also been sited in nearby states.

Keep an eye out for eggs or adults on your property. If egg masses are found, scrape them off wherever they’re attached. Because authorities are trying to monitor spread of SLF, report any siting of eggs or adults, along with photographs and location (888-4BADFLY or spottedlanternfly@dec.ny.gov, for instance).

Insecticidal soap and Neem are two organic insecticides that are effective against SLF. Both are contact insecticides so will not kill insects that arrive after spraying. 

By keeping an eye out for SLF and helping to limit its spread, we can keep this pest in check at least until some natural control can step in for the job.Spotted lanternfly

Somethings Old, Somethings New, Nothing Blue

Rare and/or Perennial

I usually draw a blank when someone asks me “So what’s new in your garden for this year?” Now, with the pressure off and nobody asking, I’m able to tell.

Of course, I often try new varieties of run of the mill vegetables and fruits. More interesting perhaps, would be something like the Noir de Pardailhan turnip. Turnip Noir de PardailhanThis ancient variety, elongated and with a black skin, has been grown almost exclusively near the Pardailhan region of France. Why am I growing it? The flavor is allegedly sweeter than most turnips, reminiscent of hazelnut or chestnut.

I planted Noir de Pardailhan this spring but was unimpressed with the flavor. Those mountains near Pardailhan are said to provide the terroir needed to bring out the best in this variety. (Eye roll by me. Why? See last chapter in my book The Ever Curious Gardener for the skinny on terroir.) I’ll give Noir de Pardailhan another chance with a late summer planting.

Also interesting is Nebur Der sorghum. This seeds of this variety, from South Sudan, are for popping, for boiling, and for roasting. What sorghum has going for it is that it’s a tough plant, very drought resistant and cosmopolitan about its soil. With my previous attempt with sorghum, with a different variety, the seed didn’t have time to ripen. Nate Kleinman, of the Experimental Farm Network, where I got Nebur Der seed, believes this variety may ripen this far north.

Nate also suggested some perennial vegetables to try — that’s right, vegetables you plant just once and then harvest year after year. I planted Caucasian mountain spinach (Hablitzia tamnoides), a relative of true spinach, and, as predicted, growth is slow this, its first, year. Hablitzia, Caucasian mountain spinachNext year I can expect a vine growing 6 to 9 feet high and which is both decorative and tolerates some shade. What’s not to like? (I’ll report back with the flavor.)

Andy’s Green Multiplier Onion (Allium cepa var. aggregatum), also from the Experimental Farm Network, will, I hope, fill that early spring gap here when some onion flavor can liven salads. Multiplier onionLater in the season, cluster of bulbs form, similar to shallots, although forming larger bulbs. They can overwinter and make new onion greens and bulbs the following years.

And finally, again from Nate, the New Zealand strain of perennial multiplying leek (Allium ampeloprasum). This seems to be a variable species, with some members yielding large bulbs know as elephant garlic. The flavor might vary from that of leek to that of garlic.

One more perennial plant (this one for the greenhouse so not really perennial here), is jicama (Pachyrhizus erosus), a climbing vine in the pea family. The flavor and texture of the large, turnip-shaped root is something like water chestnut. The flavor of the other parts of the plant are . . .  not to be tried. All other parts are poisonous! The greenhouse is so hot in summer that I figured this is one of the few plants, besides figs and ginger, that would thrive there.

Probably not. I should have researched before planting: Jicama roots are poor quality unless the plant experiences a long period of warmth with short days. But when short days come around, my greenhouse is starting to fill with lettuce, mâche, spinach, and other fresh greenery for winter salads.

Could Be Frightening, But Not

At least one more newish crop made it into my garden this year, one that I hope is not perennial. The plant is sometimes called yellow nutsedge, sometimes chufa, and sometimes tiger nut or earth almond. When I lived in southern Delaware, “yellow nutsedge “would strike terror in the hearts of local farmers; it’s been billed as “one of the world’s worst weeds.”

But there are two botanical varieties of yellow nutsedge. That weedy one is Cyperus esculentus var. esculentus. The one that I am growing is C. esculentus var. sativus. The latter is not weedy; it rarely flowers or sets seed, and doesn’t live through the winter. Both varieties, being sedges, enjoy soils that are wet but also enjoy those that are well-drained.Chufa plants growing

The edible part of chufa are the dime-sized tubers, which are sweet and have flavor likened to almonds. I did grow the plant once and thought the tubers tasted more like coconut. Chufa tubersThe problem was separating the small tubers from soil and small stones. I have a plan this time around — more about this at harvest time.

I’ll be in good company growing chufa. We humans munched on them in the Paleolithic period and they were good food to the ancient Egyptians. Hieroglyphic instructions detail the preparation of chufa for eating, as a sweet, for instance, ground and mixed with honey.

Even today, chufa is enjoyed in various parts of the world. The chufa harvest is anxiously awaited each year in Spain, when the dried tubers are washed and pulverized, then made into a sugar-sweetened “milk” know as “Horchata De Chufas.”

My Compost for a Bin

Compost, All Good, In Time

One problem with gardening, as I see it, is that much of it is about delayed gratification. Even a radish makes you wait 3 weeks after sowing the seed before you get to chomp on it. With a pear tree, that wait is a few years.

Which brings me to compost. Now that the flurry of spring pruning and planting have subsided, I’m starting this year’s compost cycle again — that’s compost for use next year. Delayed gratification again.
Food waste, yard waste, and compostable paper make up 31% of an average household’s waste which, if landfilled, ties up land and contributes to global warming. Composted, it feeds the soil life and, in turn, plants, and maintains soil tilth, that crumbly feel of a soil that holds on to moisture yet has plenty of space for air. You don’t get all this from a bag of 10-10-10 fertilizer or even a bag of any concentrated organic fertilizer.

The key to good composting is to have a good bin. Any pile of old vegetables, leaves, grass clippings, old cotton clothes, straw, or wood chips will turn to compost eventually. A bin keeps everything neat, fends off scavengers, and maintains heat and moisture within.

Buying a compost bin is one option. Consider whether you’re making compost for your garden or just as an environmentally sound way to recycle what used to be called “trash.” You need a larger bin for the former use because you’ll be importing materials, such as leaves, wood chips, and manure, to bulk up the compost.

The Perfect Compost Bin?

Over the years, my home made compost bins have gone through several incarnations. Four wooden panels filled in with chickenwire made my first bin. Once a pile was made and settled a little, I removed the panels, pinned black plastic onto the compost cubes to keep in moisture, and set up the panel in the next location for a new “compost cube.”The next bins weren’t bins but just carefully stacked layers of ingredients, mostly horse manure, hay, and garden and kitchen gleanings. And then there was my three-sided bin made of slabwood.

A dramatic jump in functionality came with my bin made from 1 x 12 hemlock boards from a sawmill, notched to stack together on edge like Lincoln logs. The only problem with this system was that I had to periodically purchase and notch new boards as older ones rotted away.Which brings me to my current bin which, now, after many years of use, I consider nearly perfect. Instead of hemlock boards, these bins are made from “composite lumber.” Manufactured mostly from recycled materials, such as scrap wood, sawdust, and old plastic bags, composite lumber is used for decking so should last a long, long time.

The boards I used were 5-1/2 inches wide and 1 inch thick. A couple of inches from either end of each 5-foot-long board, I cut a notch on each side to a depth one-quarter the width of the board and about 1/8” wider than the their thickness.When finished, I ripped one board of the bin full length down its center to provide two bottom boards so that the bottom edges of all 4 sides of the bin would sit right against on the ground.Before setting up a bin, I lay 1/2” hardware cloth on the ground to help keep at bay rodents that might try to crawl in from below.Compost bin, hardware clothWith the Lincoln-log style design, the bin need be only as high as the material within while the pile is being built, and then “unbuilt” gradually as I removed the finished compost.

June 2024 update: As you might note from the photos in this post, I made lots of compost bins, actually too many. What was I thinking? I’ve now decided to sell off some of these bins. About 28 boards, each 4′ long, are needed for a completed bin. I’m selling each board for $5, so a complete bin of 28 boards would cost you $140, more or less, depending on the bin height you want. I do make lots of compost so only have a few bins to sell. Contact me if you’re interested (845-616-0710 or through my website, but not Messenger).

Feed the Beast(s)

Okay, time to feed my compost “pets.” Nothing fancy, just any spent plant from the garden, kitchen trimmings, old clothes made from natural materials, hay scythed from my meadow, horse manure from a local stable, and occasional sprinklings of soil and powdered limestone.

For interest, I’ll sometimes throw old shoes or gloves into a pile to see what’s left once the organic portion of the shoe or glove has been stripped off.By paying attention to the textures of the materials as I add them to the pile, it generally stays well aerated. If I have a load of manure and will be building up many layers of the pile at once, I water the layers as I go; it takes too long to get sufficient water down into the pile after it has been built. Once a pile is completed, I cover it with a layer of EPDM rubber roofing material, cut to fit, to seal in moisture and keep out rain.

Piles built this summer get turned once next spring so I can monitor progress and make sure they’re moist — but not too wet — throughout. The compost is used throughout next year’s growing season.

So yes, there is delayed gratification before I get to use the “black gold.” Then again, making compost is enjoyable; I get some exercise and enjoy feeding the various fungi, bacteria, and other microorganisms at work in the compost pile.

The End of Chestnuts? No!

Blight Strikes

I looked up into the tree that I had planted 20 years ago and saw what I had long feared: two major limbs with sparse, undersized leaves. Blight had finally got a toehold on the Colossal chestnut tree, which, for the past 15 years, has supplied us with all the chestnuts we could eat. (“Colossal” is the variety name, apt for the size of the chestnuts it produces.)Chestnuts falling free from burrMy first inclination, before even identifying chestnut blight as the culprit, was to lop off the two limbs. Once I got up close and personal with the tree, the tell-tale orange areas within cracks in the bark stared me in the face.Blight on chestnut barkThere is no cure for chestnut blight. Removing infected wood does remove a source of inoculum to limit its spread. In Europe, the disease has been limited by hypovirulence, a virus (CHV1) that attacks the blight fungus. Some success has been achieved using a naturally occurring virus found on blighted trees in Michigan.

There is some evidence, although not confirmed with rigorous scientific testing, that mud packs made from soil taken from the base of a tree, can slow or halt spread of the disease. The mud packs need to be applied to each disease canker and then held in place with shrink wrap, or painted or sprayed on, followed by a layer of latex paint. Not an easy job as you move higher and higher up into the tree.

Resistance

Chestnut species vary in their response to the blight fungus. American chestnut (Castanea dentata) is very susceptible; the fungus arrived here from Asia in the early 1900s, and within a half a century had killed billions of trees. European chestnut (C. sativa) was also susceptible, but was protected by the naturally spreading fungal virus.

Chinese chestnut (C.mollisima) and Japanese chestnut (C. crenata) both have some resistance — but not immunity — to the disease, and have contributed their genes to resistant varieties. Collosal, in fact, is a hybrid of European and Japanese chestnuts, and it has some resistance to blight. But, evidently, not enough. I am hoping that the previously extremely wet season contributed to the evidence of symptoms, and that some drier seasons will keep the tree alive longer.

I’m not planning to sit back and let my chestnut-eating days shrink away to nothing. For starters, keeping my tree vigorous with pruning and good fertility might keep small cracks, into which new infections could enter, from developing. Also, chestnut trees need cross-pollination, so I do have other varieties planted. Also planted 20 years ago was Marigoule, also yielding fairly large nuts. Some sources say “blight susceptible,” others saw “blight resistant;” my large tree shows no signs or symptoms of blight. Yet.

This spring I planted two more European x Japanese chestnut hybrids. I shouldn’t have felt so confident that MY trees wouldn’t get blighted. Precoce Migoule and Marsol, the two varieties I planted, are, like Marigoule, allegedly “blight resistant,” or not.

Generally, the Chinese varieties and their hybrids are the most blight resistance. And I have two of those, actually one tree on which I grafted two different varieties. Qing is pure Chinese with easy-to-peel nuts having excellent flavor. Peach, the other variety, is also pure Chinese, though the nuts are ho-hum in flavor. Both varieties have borne for me for a number of years, yet the nuts never seem ripe once they drop.

One More Thing . . .

Is your head spinning yet? One more wrinkle in this chestnut saga. It turns out that if a pure or hybrid Chinese variety pollinates a pure or hybrid Japanese variety, the latter gets dark staining of the nuts, with a loss in quality. So I was phasing out (with a chainsaw) some other Chinese varieties I had planted. Now, with blight lurking in the wings, I’m having second thoughts.

Enough negativity about chestnuts. On the positive side, Chestnut trees’ shiny, green leaves are attractive and turn a rich golden yellow color in fall. The nuts are tasty and nutritious. With their high starch and low fat content, they’ve been called “the bread tree.” Gluten-free bread tree, for those who care about gluten. 

So, do plant chestnuts. Two different varieties for cross-pollination. If I was planting again — and I might — I’d seek out trees from among Qing, Benton Harbor, Everfresh, Gideon, and Mossberger. Or, for Japanese varieties and their hybrids: Maraval, Marigoule, Labor Day, Precoce Migoule, and Marsol.

AH-CHOO!

A Dark Cloud Hovers

The end of May and early June is such a glorious time of year in the garden, with plants thoroughly leafed out yet still showing the exuberance of spring growth. (Those of you to the north of me, Zone 5 in New York’s Hudson Valley: your time will come. Y’all to the south: enjoy your camellias, southern magnolias, muscadine grapes, figs, and . . . all the plants I wish I could grow this far north.)Meadow with grassesYet even on the clearest, sunny day — and especially on that kind of day — a dark cloud hangs overhead. Hay fever, literally from hay that is, grasses; and nonliterally, from tree pollen.

Every year the small white blossoms opening on multiflora roses signal that a sneeze season is on. That’s why this late spring allergy season is sometimes called “rose fever.” Rose is not the culprit; is just an easy to note phenological indicator of the progress of the season. Each plant awakens and starts its growth cycle in spring in response to a set accumulation of warm weather. Multiflora rose sends out a signal that the culprits are at work.Multiflora roseMultiflora rose puts on its show to attract pollinators, such as bees, which transfer pollen from one plant to the next. Hay fever is from airborne pollen blown about by wind, so the flowers of these allergen plants have no need to attract insect pollinators. The non-showy culprits this time of year are grasses and oaks.

As with many other plant-related events, climate change is also leaving its mark on allergy seasons. Here in the northeast, the effect has been for the season to start earlier with a more intense peak. You would think that my multiflora rose indicator plants would keep apace with climate changes but my records, dating back for decades, indicates otherwise. (Daylength, which doesn’t change from year to year, is also sometimes a driver of plant or animal development through the season, and it can interact with temperature.)

No matter: I didn’t have to see a blooming multiflora rose the other day to know that my hay fever season was in full swing.

And the Culprits Are . . .

To at least make this allergy season more interesting, I thought I would look more closely at nearby flora and try to identify the specific culprit or culprits.

I can start by looking no further than the grassy meadow which comes to an abrupt stop at the close shorn lawn only about fifty feet to the south of my home.

With their small, nonshowy flowers, grass species are generally not easily identified. But I can narrow the field, figuratively, by species that are common in the Northeast and that I see now blooming in the meadow. The lineup, then, includes Kentucky bluegrass (Poa pratensis), sweet vernal grass (Anthoxanthum odoratum), and orchard grass (Dactylis glomerata).

According to the 1937 USDA Yearbook of Agriculture, most grasses bloom “most abundantly in early morning,” with a secondary flowering period for many of them in the afternoon. The bloom period might be delayed and prolonged in cloudy weather.

Although rain washes pollen out of the air, thunderstorms are another story. Thunderstorms are usually accompanied by winds, which lifts and blows pollen about, and the electrical charges induced by lightning throw add yet another layer of discomfort to the mix.

I just went out to the meadow to jiggle some seedheads of the culpable grasses. The pollen is heavy enough to travel only a few feet, even in a breeze.

Tree pollen is lighter  than grass pollen and launches from greater heights. So I’m adding oak to the lineup. The two oaks most common around here are red oak (Quercus rubra) and pin oak (Q. palustris), with red oak, because of its bloom time being most culpable.

So there you have it: 3 grasses and an oak. They’re all nice plants, attractive and decorative. And, in the case of sweet vernal grass, also fragrant. If only they . . .  or if only I . . . 

I have my eye out for the flowering of catalpa trees and mountain laurel shrubs this time of year. Flowering of either of these plants are a signal that that relief is in sight that my hay fever season is over for the year. Again, these plants aren’t spilling any magical anti-hay fever concoctions into the air; they are merely phenological indicators of what’s happening with other, less conspicuous, flora and fauna.
