‘SHROOMS
Home-Grown Oysters
Move over shiitakes, you fancy, reputedly healthful mushrooms offered on supermarket shelves and at farmers’ markets at high prices. Make way for oyster mushrooms.
Many of us have chosen to grow shiitakes rather than pay the high prices for them. This means laying in a stock of freshly cut hardwood logs and riddling them with holes that are plugged with inoculated dowels pieces, then sealed with wax. A dose of patience is also needed for home-grown shiitakes, even after going through all that trouble, because a year is needed until first harvest.
My logs, from two and three years ago, yielded mushrooms last spring and autumn. But those logs are sleeping now; what about mushrooms now?
Enter oyster mushrooms. Oyster mushrooms are much more cosmopolitan about their nourishment. And planted now, harvest could begin within a few weeks.
The basics of growing any mushroom are the same. You inoculate a substrate (some material high in cellulose) with purchased or home-grown mushroom spawn. Fungal threads colonize the substrate and then, after a certain amount of time or in response to some stimulation, such as being dunked in water, mushrooms pop out of the surface of the substrate. In between short rests, they’ll pop out repeatedly until the substrate is exhausted. Then you start again with a new inoculation.
Toilet Paper Mushrooms!?
A few years ago, I grew oyster mushrooms on nothing more than a fresh roll of toilet paper, which provided a conveniently configured source of cellulose. I got the spawn for inoculation from Field & Forest Products (their TeePee™ kit). All that’s needed is to pour boiling water over a roll of fresh toilet paper, let excess water drain off, then put the roll into the plastic bag that is provided.
I inoculated, as directed by filling the center tube with the mushroom spawn and sealed the bag closed. Every once in a while I opened the bag to mist the inside with water, and watch the fungus grow its way out into the paper. After colonization is complete, mushrooms started popping up from the top of the roll.
Okay, my wife did express some aversion to eating food growing out of toilet paper. And the whole setup, admittedly, is not really all that attractive.
Coffee Grounds, Another Substrate
Not to give up on winter mushrooms, I could try growing oyster mushrooms on another readily available substrate: coffee grounds, a waste product from coffee shops, bakeries, and fast food joints. I also remember a previous foray into “espresso mushrooms” a few years ago. The Pohu strain of oyster mushrooms are among the best for coffee grounds.
To inoculate, you just break up and mix the spawn, a compressed mass mixed with sawdust, with (clean) hands and/or a knife in with the coffee grounds. The mixture then goes into a (clean) bucket having drainage holes, which, after a thorough watering, is covered with the plastic bag
After sitting in a bright location and misted daily, the coffee grounds becomes covered with fuzzy, white fungal threads. Within a few weeks, fat mushrooms swell up from the substrate, ready for harvest when their caps become just concave.
In my previous experience with espresso mushrooms, I remember an invasion of fruit flies having a field day on and in the coffee grounds. Or were they fungus gnats? Avoiding overwatering should keep fungus gnats in check, and fruit fly season is past, so espresso mushrooms are worth another try.
The nice thing about growing oyster mushrooms on coffee grounds is that there’s no need to purchase new spawn when production slows. A nice chunk of the exhausted coffee grounds can be used to inoculate some fresh grounds.
The cleaner everything that comes into contact with the spawn and the substrate right from the start, the less chance for contamination and the longer the process can be kept going. It can become an indoor game, to see how many oyster mushroom cycles can be grown before new spawn is needed again. In addition, of course, there’ll be some tasty harvests.
An Early Spring, For Shiitakes
Now that I think of it, I could be sitting down to a meal with fresh shiitakes — just fool some logs into thinking it’s spring. Which it is, in my greenhouse. I’ll move a couple of logs in there, where I’ll bet the warmth and high humidity will soon pop out some mushrooms.
A WINTER DAY WITH SPRING IN THE AIR
Spring Dreams
Looking out a window today, all I see is white, a thick blanket of snow covering the ground and howling winds periodically puff clouds of it swirling into the air. Still, I can feel the pull of spring. Perhaps it’s the bright sunlight. Couple that with the colorful gardening magazines and catalog strewn on the kitchen table, and how can I resist vicarious planting — by ordering plants instead.
David Austin roses, whose blooms have the look and fragrances of yesteryear (pastel colors and blowsy form), and the repeat blooming of pest-resistance of presentyear roses, are always a draw. Every year, new varieties are offered, some, I’m gad to see, that are cold-hardy to zone 4.

And m–m-m-m, the thought of picking fresh, ripe sweet cherries is also enticing. No, no! I ordered and planted what was allegedly a self-fertile Compact Stella cherry tree seven years ago. It wasn’t compact and it has yet to bear a cherry. I tell others that sweet cherries are a poor bet around here because of winter cold, spring frosts, and various inset and disease pests. And, after that, even if fruits do develop, birds will likely eat them. I should have been listening when I dispensed that advice.
The cherry tree has one more season to prove it’s worth. If it doesn’t, I have a replacement plant (hardy orange, Citrus trifoliata) anxiously waiting in the wings.
I’ve always wanted to plant a magnolia, of which there are many newer and older varieties, but where could I plant it? Now that I think of it, I did plant a magnolia last spring. It died. And a few years back, I planted a sweetbay magnolia (Magnolia virginiana) purchased on an impulse at a nursery a few years ago. I remember planting it, but not what happened to it, except that it’s no longer around.
The magnolia that I really want to plant is southern magnolia, Magnolia grandiflora. This large evergreen gracing many homes from Virginia southward with its large, glossy, dark green leaves and it’s large, lily-white, fragrant blossoms seems to politely call for a chair in its shade, a frosty mint julep on the armrest.
Problem is that southern magnolias are not hardy here — yet. I know of a gorgeous tree about an hour south of here and two varieties — Edith Pogue and Bracken’s Brown Beauty — are hardy below zero degrees F. It hardly gets below zero here these past few winters and, with global warming . . . ?
Yes, it is hard to keep my wits about me as spring approaches, and will be increasingly so as spring edges in. “I will not buy another sweet cherry tree, I will not buy another apricot tree (even more problematic), I will not buy another magnolia (yet), . . .”
Dorris, I’d Like To Meet You
Uh oh, another new variety of filbert from the breeding program at Oregon State University. This variety, Dorris, is, like some of its recent predecessors, immune to the eastern filbert blight that has for so long made filbert growing east of the Rockies unfeasible. They’re breeding blight-resistant filbert in Oregon because the blight fungus has made its way west.
Filbert nut harvest last fall
But eastern filbert blight is a capricious fungus, sometimes changing in a way that let’s it attack even “resistant” filberts. So I’m constantly cutting down diseased filberts and replanting “resistant” ones. One of the newest varieties, which will get a spot in the line of filberts that draws my eyes and footsteps along the edge of meadow, is Dorris.
Good luck Dorris.
Making Trees
Some trees and shrubs coming to my garden this year are going to be home-made, that is, created by me from seeds, cuttings, or grafts. To that end, I recently collected hackberry seeds as well as scions (for grafting) of persimmon, pear, and cornelian cherry, and packed them all away in an insulated box in my garage. I will deal with them in a few weeks.
Gathering scionwood
Collecting scionwood for grafting segue nicely with pruning. From the prunings strews about on the ground, I cut and save one-year-old stems into foot-long sections.
NO SIGN OF SPRING HERE YET, BUT . . .
The Onion Cycle Begins Again
Early February, February 6th to be exact, was the official opening of my 2017 gardening season. No fireworks, waving flags, or other fanfare marked this opening. Just the whoosh of my trowel scooping potting soil into a seed flat, and then the hushed rattle of seeds in their paper packets. And the grand opening was not for a flamboyant, who-can-reap-the-earliest-meal of a vegetable like peas or tomatoes.
No, the grand opening for the season is rather sedate: I sowed onion seeds in mini-furrows in a seed flat. Why onions? In addition to the fact that I love the flavor of onions raw and cooked, onions need a long growing season. The summer growing season is cut short because the plants stop growing new leaves to put their energy into swelling up their bulbs when daylengths grow sufficiently long, 14 hours long, to be exact. Around here, that happens sometime in May. The more leaves the plants make before then, the bigger the bulbs. Hence my early planting.
So I poured about a 3-inch depth of potting soil into an 18 by 24 inch plastic tub in which I had drilled drainage holes, and then made seven parallel furrows in the soil into which I dropped onion seeds. This year I’m growing New York Early, Patterson, and Ailsa Craig. (I also sowed leeks in one of the furrows.) After closing up the furrows, I watered, covered the tub with a pane of glass, and put the tub on a heating mat set at 75 to 80° F.
Done. The season has begun.
Other Beginnings
There are so many ways to grow onions. Let me count the ways, some other ways.
1, and easiest, is to just plant onion sets, those mini-onions you can buy to plant as soon as the ground outside warms and dries up a bit. One downside to sets is that the variety selection is very limited. Not only limited, but also restricted to so-called “American-type” varieties, which keep very well but are very pungent and not very sweet. Onion sets that are too large — larger than a dime — tend to go to seed. Plants going to seed look very pretty but don’t make bulbs for eating.
Number 2 method overcomes one of the limitations of method number 1: Purchase onion plants, which are growing plants, with leaves. The sweet “European-types” — Ailsa Craig, Sweet Spanish, and Granex, for example — are available in this form. The plants are grown in fields in the South, and there’s the potential to bring a disease into the garden on these plants. Also, “organic” onion plants might be hard to find.
Setting out onion transplants
Method number 3 is the most involved. (I’ve never tried it.) Grow your own onion sets. The trick is to sow the seeds outdoors densely enough so that they bulb up while still small — dime size. Once bulbs mature, their harvested to store for winter, and then planted in spring just like the sets in Method 1.
Method number 4 is fairly easy, and that is to sow seeds of the Evergreen variety onions right in the ground in spring. This variety never forms bulbs but makes tasty green onions, or scallions. It’s also perennial, so any scallions left in the ground will multiply year after year. The downside here is that you don’t get onions for winter. I grow these every year and do get them for winter use also, in my greenhouse.
Method number 5 is easiest of all. Grow Egyptian, or Walking, onions. This is another perennial onion. It “walks” by forming bulblets on top of some stalks. The weight of the bulblets pulls down the stalk, and when the bulblets touch ground, they root to make new plants. The new plants eventually send up bulblet-topped stalks which likewise bend to the ground, etc., etc., walking the plants around. To me, Egyptian onions are all hotness with little other flavor. I no longer grow them.
Walking onions
I learned of method number 5 from Jay at Four Winds Farm. Simple enough. Just sow the seeds outdoors as soon as the ground is warm enough and dry enough for a nice seedbed. A nice seedbed is key here, because onions compete very poorly with weeds and the goal is to get the seeds to germinate as fast as possible. I tried this last year and the bulbs ended up pretty much the same size as those from the plants I sowed last February and then transplanted into the garden in April. So I get a wide choice of varieties without having to start the seeds in February. Thanks Jay. (I’m growing transplants and direct seeding this year, just to make sure.)
My Pea Planting Will Not Be On St. Pat’s Day!
My early February onion-sowing date isn’t some magical date. My greenhouse is only minimally heated, making for very slow growth early in the season. Growth picks up as sunlight grows more intense and further warms the greenhouse. A week or more difference in sowing date early in the season doesn’t translate into that much difference in growth near harvest time.
The same goes for pea-planting, which is attended by more fanfare than onion planting. Many gardeners rush to get their pea seeds planted by St. Patrick’s day, but planting a week later doesn’t delay that harvest by a week. Perhaps by a couple of days or by a few hours, depending on the season. And anyway, St. Patrick’s day might be the traditional date for planting peas in Ireland, but it would be way too early in Maine and way too late in Georgia. I plant peas here in Zone 5 on April 1st, give or take a few days.
In my book Weedless Gardening, I have a chart that shows what and when to plant, whether as seeds, indoors or out, or as transplants, for all regions. All you have to do is plug in your average date for the last killing frost of spring and the first killing frost of autumn. This date is available from your local Cooperative Extension Office.
