MY SAVINGS ACCOUNTS

Reasons to Save

I’m saving seeds of some of this year’s juiciest tomatoes and most colorful flowers to plant in next year’s garden. Why? Saving my own seed from year to year gives me a bit of independence from seed companies, which, for one reason or another, may stop offering certain varieties.

It’s also a way way to maintain an annual supply of seeds that seed companies never offer, so-called heirloom varieties that have been handed down for generations from parents to children and from neighbor to neighbor. Read more

SOW A (FIGURATIVE) SEED

An Oasis

It’s not the time of year to inspire most of us gardeners to sow a seed, but sow I will, a figurative seed in your imagination. Who knows what reality it may grow into?

As the weather turns increasingly cool, then cold, and the landscape becomes washed over in gray and brown, imagine a retreat, an oasis of lush greenery and bright colored flowers suffused in warm, moist air. A greenhouse.

EASIER MEADOW PREP

Genesis

In my previous blog post, I described various ways to prepare the ground for a meadow. With that said, I admit to not following any of what I wrote about ground preparation for the meadow here on the farmden. Not that my instructions were wrong. As the old Chinese proverb goes, “There are many paths to the top of the mountain, but the view is always the same.” Meadows also.Goldenrod in meadow

Last week’s meadow prep is geared to the meadow steward who wants to be presented with a riot of color for as long as possible. That view necessitates the killing of existing vegetation and sowing seeds or setting out small plants of desired species.

HOT OFF THE PRESS

A New Map

The coldest nights of the year are due to arrive in about a month. These frigid nights might test the hardiness of trees, vines, and shrubs, perhaps nipping back a few branches here or there on some plants, perhaps killing others outright. Though bitter cold is a few weeks away, I have done what I could to prepare plants for the onslaught.

The first step in preparing any plant for the winter is knowing how cold it’s going to get. There’s no crystal ball offering this information, but decades of weather data have been compiled by the U. S. Department of Agriculture to prepare the USDA Hardiness Zone Map, which is helpful in predicting the probable minimum temperature for an area. The map has gone through numerous incarnations of increasing accuracy and . . . drum roll . . . recently this year the latest incarnation was revealed.USDA Plant Hardiness Map 2023

So, what’s new? The increasing accuracy reflects minimum temperatures measured at 13,625 weather stations averaged over 30 years. As before the country is divided into zones denoted by color and number, 13 of them, the lower numbers reflecting colder regions. Each zone denotes the average coldest temperature in that time period, not the minimum temperature ever experienced.

You often see this map, the country covered over my squiggly lines filled in with a color. Big change this year: The USDA offers this map only online Read more

NOT YET OUT OF THE PUMPKIN PATCH

Today’s plans for Tomorrow’s Pumpkins

My friend Jack is already planning for next Halloween, not getting together next year’s costume, but squirreling away seeds for growing next year’s pumpkins. Jack wants good yields and he wants large pumpkins. Seeds that he bought this past spring for giant pumpkins didn’t produce any fruits. But a plant growing out of his compost pile — a “volunteer” plant — did produce a few good-sized fruits.

Jack’s question to me was whether the seeds he has saved from this productive volunteer will produce good pumpkins. My answer was, “It depends.”Field of pumpkins

First of all, it depends on what seed gave rise to that volunteer plant. Of course it was from a pumpkin. But did that pumpkin grow from a hybrid seed?

Hybrid seed is produced by deliberately crossing one plant having certain desirable traits with another plant having another set of desirable traits. Seeds from that deliberate cross grow into plants that combine the qualities of both parents.

But these qualities are not perpetuated in the seeds from the fruit of a plant grown from hybrid seed. (Yes, I wrote that correctly.) Read more

Uncovering frosted tomatoes

EXIT: TOMATOES AND PEPPERS

Listen to Lee, Lee

You’d think I would have known better or, at least, listened to my own preaching. An increasing warming spell a week ago induced many fellow gardeners around here to set tomato and pepper transplants out in their gardens. The average date of the last killing freeze around here is May 21 — but temperatures were getting warmer and warmer, and what with global warming . . . I have preached not going with your gut when it comes to times for spring planting, but was swayed with the crowd and the warming weather, and planted out over 50 tomato plants and a dozen pepper plants a couple of weeks ago.

Then the weather turned cooler, with night-time lows predicted to sink into the low 30s. Here in the Wallkill River Valley, cold air, which is denser than warm air, flows downhill like water to collect in low spots. My farmden always experiences temperatures a few degrees colder than locally predicted.

No problem. I made some wire supports over which I draped a row cover which is said to retain heat, offering about six degrees more of frost protection. I went to bed that night at peace with our planet. Read more

TOMATOES & CORN, TWO ALL-AMERICANS

Ode to Sungold

As the curtain closes on the summer garden and the autumn garden edges towards its glory, I’d like to offer thanks. No, not a religious thanks for a summer of tomatoes, peppers, cucumbers, okra, and other warm weather vegetables. But thanks to a person, the person who bred Sungold cherry tomato.Sungold near season's end

Anyone not familiar with Sungold tomato should be. It’s sweet and tangy, not at all cloying, enveloped in persimmon-orange skin. I once grew over 20 varieties of cherry tomatoes (Solanum lycopersicum var. cerasiforme), including Sungold, for a magazine article. As a friend walked down the row, sampling fruit from each plant, she proclaimed, “That’s one row of lousy tomatoes.”

Agreed, excepting a few varieties, one of which was, of course, Sungold. The other exceptions were Gardener’s Delight, Sweet Million, and Suncherry, all three of which are rarely seen these days, probably because Sungold eclipsed the others with its distinctive appearance and, I think, even better flavor.

(My cherry tomato row didn’t include marble-size, so-called currant tomatoes, botanically, S. pimpinellifolium. They are very sweet, very small, and very tasty. I don’t grow them anymore because, for me, they’re too messy, dropping fruits all over the place. The following year, seedlings can grow to become a tomato jungle.)

THE WISDOM OF SEEDS

Tweaking the View

Finally, today, I’m planting seeds. “Too late to plant seeds,” you say? Or, perhaps you’re thinking that it’s way too early, with the coldest days of the year still about a month away. Well, the seeds I’m talking about aren’t vegetable or flower seeds; they’re tree and shrub seeds.

Planting seeds is a way to get lots of new plants at little or no cost. The seeds I’m going to be planting are ones that I collected this past summer, fall, and yesterday.

I already grow way too many plants but I need these plants for a barrier. The rear of my property backs up to a rail trail which, from spring through fall, is a wall of greenery in a swath about twenty feet wide. Nothing special, just whatever popped up there naturally, mostly bush honeysuckles and some viburnums nearby with black cherries and ashes further in. Grape or bittersweet vines clamber up whatever they can latch onto. Leafless, now, these plants don’t present a particularly pretty sight.

What’s needed is some winter color and greenery. Closer in, I’m planning a screen with winterberry (Ilex verticillata), Meserve holly (Ilex x meserveae), and arborvitae (Thuja occidentalis, this one purchased as plants).

A couple of larger trees — black tupelo (Nyssa sylvatica) and red maple (Acer rubrum) — will beef up the naturally rag tag mix of trees further in.

Nanking cherry spring and summer

I’m also sowing seeds of Nanking cherry (Prunus tomentosa). It’s one of my favorite large bushes for its spectacular show of pinkish white blossoms in early spring and its equally spectacular show and abundance of delicious, juicy, small cherries in summer. All on a carefree, very tough and very cold-hardy plant.

Seed: Awaken

Seeds of woody plants that ripen in early summer will sprout almost as soon as they touch down to soil. Red maple (Acer rubrum) is a good example of an early-ripening seed.

A friend collected some from his trees. I sowed them, they sprouted quickly, and I now have some healthy seedlings a foot or so tall.

Many woody plants bear seeds that don’t ripen until late summer or early fall. If these seeds sprouted as soon as they touched soil, the resulting tender, young sprouts would succumb to winter cold. To avoid this, they sit and wait until they feel that winter has passed. They gauge this, via their hormones, by the amount of cold they’ve experienced. Levels of the hormone abscisic acid, which keeps seeds dormant, decrease as cold wears on.

Seeds typically need exposure of one to two months, or about 1,000 hours, in a moist, cold environment before they can be convinced that it’s safe to sprout. Cold temperatures, between about 30 and 45 degrees Fahrenheit, not frigid temperatures, are what flick this switch. Depending on location, such temperatures might be experienced partly in fall and partly in spring, or mostly in fall.

Other types of dormancy might also need to be overcome before a seed will sprout. Some seeds have a separate dormancy for root growth, overcome with warm, moist conditions. Root growth must precede shoot growth.

Warm, moist conditions also may be initially needed for seeds with especially tough coats, to soften them or give microbes the opportunity to erode the surface.

Practical Matters

To start, I’m soaking the winterberry, holly, black tupelo, and Nanking cherry seeds in water for a couple of days, changing the water daily. Soaking does three things: First, it makes sure the seeds are well hydrated; second, it makes fruits fall apart to release their seeds; and third, it leaches out potential sprouting inhibitors. Sprouting inhibitors prevent seeds within moist, fleshy fruits from sprouting within.

Winterberry, Nanking cherry, black tupelo, and holly seeds

In a couple of days, I’ll plant my soaked seeds in flats of potting soil, water them, cover them, and set them in my garage. (The holly and winterberry fruits still are more or less intact so I’ll just plant the whole fruits in the potting soil.) In the garage, temperatures are somewhat moderated as compared with outdoor temperatures.

As soon as the seeds sprout — still, after many years of doing this, an exciting moment for me — I’ll move them to a bright window, the greenhouse, or, depending on outdoor temperatures, outdoors.

After a few inches of growth, individual plants get more space in their own pots or a nursery bed. And, after a year or two, they move to their permanent homes.

I took seeds for the hollies and winterberries from clonal plants, that is, plants of named varieties. Clonal plants are exact replicas of the mother plants from which they were propagated. The holly varieties were all female, the variety Blue Princess, except for one male, Blue Boy, there to provide pollen so the Princesses would bear their flashy red berries. I can’t remember the variety name of my female winterberry.

Each of the seedlings I’ll be growing will be a genetic mix, each different from each other and their mothers, although not necessarily obviously so. In the case of holly and winterberry, half of the seedlings will, theoretically, be the more desirable females. (One male can sire as many as about eight females.)

All this may seem like a lot of trouble when I could just purchase plants from a nursery. But I find looking at a mature plant that I planted very rewarding. The amount of satisfaction I get is indirectly proportional to the size of plant I started with. Hence, growing trees and shrubs from seeds is especially satisfying.

FILBERT NUTS OR HAZELNUTS?

Species Matter; Varieties Matter

You say “tomayto,” I say “tomahto.” You say “filbert,” I say “hazelnut.” (“Filbert” is from St. Philibert, to whom August 22nd, is dedicated and which is the day of first ripening of hazelnuts in England.) Although hazelnuts originally referred to native American filberts, hazelnut and filbert are now equivalent.

It’s been over twenty years since I planted my first hazelnuts. Fortunately, hazels bear quickly, often within 3 or 4 years. Unfortunately, a disease called eastern filbert blight can decimate the trees, and not begin to do so for about a decade. Our native hazels (Corylus americana), having evolved with the blight, are resistant. Not so for European hazels, which are the hazelnuts of commerce.Native hazel

My first planting was of our native hazel, which I planted for beauty and for nuts. It did turn out to be an attractive, suckering shrub that lit up fall with its boldly colored leaves. The nuts themselves were less notable: small and not very good tasting.

Next I planted a few old varieties of hybrid hazels, Graham, Gellatly, and Halls Giant, followed, a few years later by Tonda di Giffoni, Lewis, and Clark. All were billed as blight resistant and did quite well. In the 1960s eastern filbert blight made its way to the Pacific Northwest, the hotbed of commercial hazelnut production in the U.S. (providing 99 percent of domestic hazelnuts), which prompted breeding of resistant varieties. Lewis and Clark are two such varieties. Two more such varieties, Santiam and Yamhill, were added to my collection 11 years ago.MY hazel plantings

Right on schedule after about ten years, black pustules of blight began to show up on branches, which start to die, then finish. But the varieties I planted were blight resistant, you say. Resistance is a matter of degree (“immune” means no disease), and the varieties I planted evidently were not sufficiently resistant. 

Blight pustules on stems

This doesn’t at all reflect poorly on breeders of these not-quite-resistant-enough hybrids. The blight fungus is capricious, changing with location and, perhaps, over time. I dug up and out all the nonproductive, diseased plants.

But I like filberts. Enter a few breeders breeding filberts right here in the northeast. One is Dr. Tom Molnar of Rutgers University, from whom I got a few selections (with nonluscious, early selection names like CR X R03P26 and CR X R11P07), which I planted back in 2014. And Jeff Zarnowski, of Z’s Nutty Ridge Nursery. And others. So now I grow Geneva (aka Gene, from Grimo Nut Nursery), Truxton, Dorris (another selection from Oregon), Raritan (a more advanced selection from Rutgers), as well as my original Rutgers plants.

I’m ready to cull again any varieties that catch blight or whose nuts are too small. For wherever plants are culled, I have potted plants of Monmouth, Hunterdon, and Somerset — all advanced Rutgers selections — waiting in the wings. 

Streamlining Processing (On a Very Small Scale)

As with fruits in general, this year was also the best ever for nuts that I grow. Even the English walnuts (Juglans regia) bore a crop this year, their first substantial crop, all from 6 walnuts I planted back in 2006. I didn’t have high hopes for walnuts because they are susceptible to anthracnose disease, late frosts, and squirrels, which could conveniently harvest the nuts from the overhead squirrel highway along the road.

And the filberts — oodles of them. Mostly, we just shell and eat them. That’s fine. But for cooking with them or concocting a delicacy such as, say, fig-hazelnut jam, shelling nuts one at a time is too slow.Basket of filberts

A quick web search turned up a couple of very elegant, home made shellers that work reasonably well. Luckily, before I delved too deeply in how I was going to fabricate one of these out of metal, I did a web search and found one available for about $30.

(These kitchen counter hazelnut sheller are manufactured in Turkey, which grows 70 percent of the world’s hazelnuts. Want another fun fact? Twenty-five percent of the world’s production goes into making Nutella and Ferrero Rocher, both hazelnut and chocolate confections made by the Luxemburger company Ferraro.)Turkish nut sheller

One problem with the sheller is that it needs adjustment for nut size, so it is recommended to do some sorting into size ranges before running nuts through the sheller. This I could make myself, easily. Basically, it is an open wooden box whose bottom has 3/8 inch square, wooden dowels spaced 5/8 inch apart, which is pretty much the size of my largest hazelnuts in the shell. The corners of the box are joined by hinges so that the sides can be moved to deform the shape. As the box deforms increasingly to a parallelogram, the distance between the dowels decreases. A pegged slat from one side of the box to n adjacent side holds the box to the desired shape and dowel spacing.

So I just adjust the box to the smallest dowel spacing needed, about 3/8 inch apart, dump on a bunch of nuts, and shake. Then I move the spacing up to about 1/2 inch, then shake again. And finally, move spacing to 5/8 inch, and . . .  well, you know.

Hazelnut size selector

I could be on my way to hazelnut butter, chopped hazelnuts sprinkled on everything, that fig-hazelnut jam, perhaps even home made Nutella. No rush. Once sufficiently dried (to 6 percent moisture, which takes a couple of weeks), hazelnuts store well in their shells for over year. Shelled and refrigerated, they keep for for about six months
