00:00Here is a crop you can grow with no garden, no ground, no sunshine, and no fine weather.
00:07You can grow it in a dark corner of a cellar, in a shed, in a cubby under the stairs,
00:12in
00:13the coldest and gloomiest part of your house where not one green thing would ever survive.
00:19You can grow it in the dead of winter, when the ground outside is frozen hard as iron,
00:24and in six to eight weeks it will feed you and keep feeding you in flush after flush.
00:31I am talking about mushrooms.
00:34And I will tell you plainly, most folks think growing mushrooms is some difficult, fussy
00:40business needing special equipment and a scientist's care.
00:44It is not.
00:45The old people grew mushrooms in cellars and barn corners for generations with nothing but
00:52a box, some well-rotted manure, and patience.
00:56My grandfather kept a mushroom bed in the far corner of the root cellar, past the potato
01:01bins where it was darkest and coolest, and as a boy I thought it was the strangest thing
01:07on the whole farm.
01:09A wooden crate of old manure sitting in the dark, and out of it, every so often, my grandmother
01:15would come up the cellar steps with an apron full of mushrooms in the middle of February,
01:21when there was not a green thing growing for fifty miles in any direction.
01:27That struck me as very near magic, and in a way it is.
01:31Everything else on the place slept through the winter.
01:34That box did not.
01:37He used to say a cellar corner that grows nothing is a corner going to waste, and he was right,
01:43and I have kept a box going ever since.
01:46I am going to show you the whole of it today, start to finish, and you will need almost nothing
01:52you do not already have.
01:54My name is Elias Yoder, and I farm here in Lancaster County in Pennsylvania.
02:00And a mushroom is a curious and wonderful thing, unlike anything else you grow.
02:06It is not a plant at all.
02:08It has no leaves and no roots as a plant has them, and it needs no sunlight, for it does
02:14not eat the light the way a green plant does.
02:18It is its own kind of living thing altogether, neither plant nor animal, and what it does
02:24for its living is eat what is dead and rotting and turn it back into good, rich earth.
02:31Fungi are nature's great recyclers.
02:34That is their whole office in creation, to take what is died and break it down so it can
02:41feed what lives.
02:42And when you grow mushrooms, you are simply putting that ancient work to your own use,
02:48and taking a supper out of it besides.
02:51Before I go on, I will say this once and then leave it be.
02:54I gathered the whole of it, all these old ways of growing your own food, into a book.
03:01You can find it at EliasYoder.com.
03:05The book is the long version.
03:07If you want it, it is there.
03:09I will not mention it again.
03:11Let me tell you what you need, and it is a short list.
03:15First, a box.
03:17A stout cardboard box will do, though I would use two, one inside the other, for a single
03:24one goes soft as it takes up the damp.
03:26Better still is a wooden crate, or a shallow wooden box, which is what I use, lined with
03:33cardboard to keep the mix from falling out the cracks.
03:37Whatever you use, you want it a good six inches deep at the least, and deeper is fine.
03:43If you are using an old crate that has held something before, wash it well with hot, soapy
03:49water, and rinse it and let it dry before you start, so that no stray spore of some wild
03:56fungus is lurking in it to compete with your crop.
04:00Start clean.
04:02Second, and this is the heart of it, you need something rich and rotted for the mushrooms
04:07to feed on.
04:08The very best thing is well-rotted manure, good old cow manure that has aged and composted
04:15down until it is dark and crumbly and sweet-smelling.
04:19And I want to be plain about this, for it matters.
04:23It must be well-rotted.
04:25Do not use fresh manure.
04:28Fresh manure is far too strong and hot and full of things that will burn your mushrooms
04:34and ruin the whole business.
04:36Aged, rotted, mellow manure is what you want, the kind that has sat a good long while.
04:43If you cannot lay hands on good rotted manure, a quality all-purpose potting soil will serve,
04:50or a half-and-half mix of the two, and both do well.
04:55Third, you need mushroom spawn, and this is the one thing you will have to send away for.
05:02Spawn is the seed of the mushroom, if you like.
05:06What it actually is, when you look close at it, is grain, ordinary cereal grain, that
05:12has been run all through with the fine white threads of the mushroom, what folks call the
05:18mycelium, which is the root work of the fungus.
05:23That grain is just a carrier, a way to hand the living threads over to you so you can set
05:29them in your rich manure and let them go to work.
05:33You buy that spawn from a supplier, and it is the one purchase in this whole business.
05:39And last, a bit of newspaper to lay over the top, and something to mist water with.
05:46That is the whole of your outfit.
05:48Now, which mushrooms?
05:50Today, we are growing the common button mushroom, the very same one you buy at the store.
05:57And here is a thing worth knowing that surprised me.
06:01The little white button, the larger white mushroom, and the great flat portobello are all the very
06:08same mushroom.
06:10They are not different kinds at all.
06:12They are just the same mushroom picked at different ages, young, middling, and full grown.
06:20So when you grow buttons and let a few go on growing, you have portobello's.
06:25And the brown chestnut mushroom is a very near cousin of the same family, grown just the
06:32same way.
06:33All of them love good rotted manure.
06:37So let us begin.
06:38Take your rotted manure and get it to the right dampness.
06:43For this matters as much as anything.
06:46You want it damp all through, but not sodden.
06:50And here is the old test for it.
06:52The same squeeze test I have given you for soil before.
06:57Take up a good handful and squeeze it hard in your fist.
07:01You should see just a few drops of water come out between your fingers, a drip or two,
07:07no more.
07:08If water runs out in a stream, it is too wet and you must add dry material.
07:15If nothing at all comes out, it is too dry and wants more water.
07:20A few drops.
07:22That is your mark.
07:23Get your hands right in there and mix it up well, and do not fuss about the manure, for
07:29it is all good, clean, rotted stuff by now and your mushrooms will love it.
07:36Fill your lined box with that damp manure to about two-thirds of its depth and level it
07:42off nice and even.
07:44Now for the spawn.
07:46Take your grain spawn and break it up well with your hands, rolling it between your palms
07:52so the grains come apart from one another rather than staying in clumps.
07:57That way it spreads through the manure evenly and gets going faster all over.
08:04As to how much, more is better here.
08:07The more spawn you put in for the amount of manure, the quicker those white threads run
08:13all through it and the better your chance of success.
08:17For a fast-spreading crop leaves no room for any other stray mold to take hold.
08:24So be generous with it.
08:27Scatter your broken-up spawn over the surface and then mix it into the top few inches of
08:33the manure, working it through so it is well distributed.
08:37Then level it off again.
08:39And then you tuck it in.
08:41Take some newspaper, wet it thoroughly so it is sodden, and lay it right over the top
08:47of the whole box, tucking it down at the sides.
08:51That damp paper does one job and does it well.
08:55It slows the water from drying away and keeps everything underneath snug and evenly moist,
09:03which is what those threads want above all.
09:06Then mark your box with the date and the kind of mushroom, so you know what you have and
09:13when you started.
09:14Now the box goes somewhere dark and airy.
09:18Remember, this crop wants no light at all, which is why a cellar or a shed or a dark cupboard
09:25suits it perfectly.
09:26But it does want air moving, so do not shut it up air tight.
09:32And it wants a mild warmth, a comfortable indoor sort of warmth.
09:37Too hot and you will harm the threads.
09:41Too cold and they will simply stall and sit there doing nothing.
09:45A cool room in the house, a cellar that stays mild, that is the place.
09:51Somewhere between a chilly room and a comfortable one, and out of the light.
09:56Then you wait, and you check it every couple of days.
10:00If the surface looks at all dry, give it a light misting.
10:04Just a spray, no more.
10:06And I want to stress that, nicely moist, never sopping.
10:11Overwatering is the commonest way folks ruin this.
10:14A light misting every couple of days is plenty.
10:18In about ten days to a fortnight, you will see the first fine white threads spreading
10:24through the mix, like the finest cobweb running through the dark manure.
10:29That is the sign that it is taken and all is well, and it is a fine thing to see.
10:34Then, over another week or so, those threads spread and thicken until the whole surface
10:41of your manure has gone near white with them, run through and through.
10:46When you see that, the first stage is done, and you are ready for the last step.
10:51And that last step is the trick that makes the whole thing work, so pay attention here.
10:57Those white threads, left alone in the dark forever, would just go on spreading and never
11:03give you a single mushroom.
11:05They have to be told it is time to fruit, and the way you tell them is by laying on
11:11what
11:11growers call a casing layer, a covering of a different material over the top.
11:17When those threads come up into that new covering and find it, something in them changes, and
11:23instead of just spreading, they begin to make mushrooms.
11:26That covering is the signal.
11:29Without it, you will get white threads and no supper.
11:33Now what to use for the casing?
11:36What you need is something that holds moisture well, but stays light and open so the air can
11:42move through it.
11:43The old growers used a light soil for this.
11:46What I use is a mix of good, sifted leaf mold, which is just fallen leaves rotted down soft,
11:54together with a bit of sifted light loam and some coarse sand to keep it open.
12:00Sifted, spent compost, if it is fine and light, does well too.
12:05What you are after is a covering that stays damp and does not pack down hard.
12:11Mix your casing material and dampen it to that same moisture, damp but not dripping.
12:17Then lay that casing right over the whole white surface, about an inch deep, spread even.
12:23And back it goes to a dark, airy place, only now you want it a touch cooler than before,
12:29the cool end of a comfortable room.
12:32And now you watch close.
12:34From this point on, look at it every day and mist it as needed, for now you want
12:40it damp and the air around it humid.
12:43This is the stretch where care pays.
12:46Keep that casing layer moist and never let it dry out.
12:50Let me tell you the few troubles that come up and what they mean so you are not left guessing.
12:56If after two or three weeks you see no white threads at all, the commonest causes are that
13:02the place is too cold and everything has stalled, or that the mix was too wet and sour and the
13:08spawn drowned in it, or that the manure was not well enough rotted and was still too strong.
13:14Move it somewhere milder and check your dampness.
13:18If you see a green or a black or a slimy growth appearing rather than clean white threads, that
13:25is a stray mold that got in and beat your mushrooms to the food, and the usual cause is a
13:31dirty box
13:32or a mix kept far too wet.
13:35Scrape out a small patch if you catch it early, but if it is spread, best to empty it out
13:40and
13:40start clean, washing everything well.
13:44And if the white threads run beautifully but no mushrooms ever come, then either you have
13:49not put on the casing layer, or the casing has been allowed to dry out, or the place is
13:55too warm for fruiting.
13:56It is nearly always one of those three, and every one of them is easily set right.
14:03And then one day you will see them, little pale buttons pushing up through the casing,
14:08and they grow astonishingly fast once they start.
14:12It is one of the great pleasures of growing your own food, and I do not think it ever gets
14:17old.
14:18Now the harvest, and there is a right way.
14:21I like to take them when they are fully formed, but still closed underneath, before the cap opens
14:27out and the gills show.
14:29That is a mushroom at its best.
14:32And here is the important part, do not cut them off.
14:36If you cut a mushroom, you leave a stump behind in the bed, and that stump sits there and rots,
14:42and the rot can spread into the crop still coming.
14:46So you take hold of the mushroom down at its base, and you gently twist and pull it up whole,
14:52root and all.
14:54Twist and pull, never cut.
14:57Then take a little of the surrounding casing material, and cover over the small hole it
15:02left so that spot stays moist and does not dry out.
15:06And here is the good news that most folks do not expect.
15:11That box is not finished after one picking, not by a long way.
15:16Mushrooms come in what growers call flushes, waves of them, and after one wave finishes,
15:23another will come on.
15:25They do not all come at once, and they will not carpet the whole box in one go.
15:30They come up here and there, so keep going over the box, taking each one as it reaches its size,
15:37and keep misting faithfully, and that box will keep giving you flush after flush for weeks.
15:44Just keep picking and keep it damp. And when at last it runs out of steam and gives no more,
15:51do not throw that spent manure away, for it is now some of the finest stuff you will ever put
15:57on a garden.
15:58All that rotted manure, worked all through by those threads,
16:03has been broken down into a rich and beautiful material, and you empty it out onto your compost heap,
16:10or straight onto your garden beds, where it will feed your vegetables.
16:14And there is the whole circle of it, closed up neat. The manure from the animal fed the mushroom.
16:21The mushroom fed you, and what is left over goes back to feed the garden that feeds you again.
16:28Nothing is wasted anywhere along the line. That is how the old farms worked, every single thing
16:37feeding into the next, and it is a way of living I wish more folks understood.
16:42Let me say a plain word about who profits from you not knowing this, and it is no dark scheme.
16:50Mushrooms are dear at the store, some of the dearest food by weight in the whole market,
16:56and the growing of them has been made to seem a mysterious and technical business
17:01best left to specialists. There is money in that mystery. There is no money at all in a man learning
17:08that a wooden box, a barrow of old rotted manure, a dark cellar corner, and one purchase of spawn,
17:16will give him mushrooms for weeks. Nobody earns a wage teaching you that.
17:23So the knowing of it slipped away into the specialist trade, and the ordinary body came
17:28to believe it was beyond him, when his own great-grandmother very likely grew them in the cellar.
17:35It is not hidden. It is only not taught, because the teaching profits no one but you.
17:42The money runs toward the store and away from the cellar, and it always has.
17:48So there is the whole of it. Line a stout box. Fill it with well-rotted manure,
17:55damped to where a squeeze gives you a few drops. Break up your spawn, and mix it through the top
18:01few
18:02inches. Cover it with wet newspaper, and set it somewhere dark, airy, and mildly warm. Mist it lightly
18:11every couple of days. When the white threads have run all through and gone near white on top,
18:17lay on an inch of damp casing to tell it to fruit, and move it somewhere a touch cooler.
18:24Then mist daily, and watch. Twist and pull your mushrooms at their best. Cover the holes,
18:31and keep going for flush after flush. And when it is spent, give it to your garden.
18:38Tell me down in the comments what county you garden in, and whether you have ever grown mushrooms
18:44before, or whether this is your first. And if there is a mushroom you have always wanted to grow,
18:50or if your own family grew them in a cellar the old way, put that down there,
18:55for I would dearly like to hear it. Next time out here, I want to show you how to build
19:00a proper
19:01compost pile the old way, layer upon layer, for that spent mushroom manure I just spoke of
19:08is bound straight for the pile, and the pile is the beating heart of every single thing I grow.
19:15It is past time I showed you how to build one right. But for now, remember this. There is food
19:21to be had
19:22in the dark corners of your house, in the dead of winter, out of what another creature left behind.
19:28Nothing on a well-run place is ever truly waste. It is only food that has not yet found its
19:35next mouth.
19:36The people who built this country with their hands knew that, and we are only just starting to remember.
