Mushrooms: how to grow them.

PREFACE

Mushrooms and their extensive and profitable culture should concern every one. For home consumption they are a healthful and grateful food, and for market, when successfully grown, they become a most profitable crop. We can have in America the best market in the world for fresh mushrooms; the demand for them is increasing, and the supply has always been inadequate. The price for them here is more than double that paid in any other country, and we have no fear of foreign compet.i.tion, for all attempts, so far, to import fresh mushrooms from Europe have been unsuccessful.

In the most prosperous and progressive of all countries, with a population of nearly seventy millions of people alert to every profitable, legitimate business, mushroom-growing, one of the simplest and most remunerative of industries, is almost unknown. The market grower already engaged in growing mushrooms appreciates his situation and zealously guards his methods of cultivation from the public. This only incites interest and inquisitiveness, and the people are becoming alive to the fact that there is money in mushrooms and an earnest demand has been created for information about growing them.

The raising of mushrooms is within the reach of nearly every one. Good materials to work with and careful attention to all practical details should give good returns. The industry is one in which women and children can take part as well as men. It furnishes indoor employment in winter, and there is very little hard labor attached to it, while it can be made subsidiary to almost any other business, and even a recreation as well as a source of profit.

In this book the endeavor has been, even at the risk of repet.i.tion, to make the best methods as plain as possible. The facts herein presented are the results of my own practical experience and observation, together with those obtained by extensive reading, travel and correspondence.

To Mr. Charles A. Dana, the proprietor of the Dosoris mushroom cellars and estate, I am greatly indebted for opportunities to prepare this book. For the past eight years everything has been unstintedly placed at my disposal by him to grow mushrooms in every way I wished, and to experiment to my heart's content.

To Mr. William Robinson, editor of _The Garden_, London, I am especially indebted for many courtesies--permission to quote from _The Garden_, "Parks and Gardens of Paris," and his other works, and to ill.u.s.trate the chapters in this book on Mushroom-growing in the London market gardens and the Paris caves, with the original beautiful plates from his own books.

The recipes given in the chapter on Cooking Mushrooms, except those prepared for this work by Mrs. Ammersley, although based on the ones given by Mr. Robinson, have been considerably modified by me and repeatedly used in my own family.

My thanks are also due to Mr. John F. Barter, of London, the largest grower of mushrooms in England, for information given me regarding his system of cultivation; to Mr. John G. Gardner, of Jobstown, N. J., one of the most noted growers for market in this country, for facilities allowed me to examine his method of raising mushrooms; and to Messrs. A.

H. Withington, Samuel Henshaw, George Grant, John Cullen, and other successful growers for a.s.sistance kindly rendered.

MUSHROOMS, HOW TO GROW THEM.

CHAPTER I.

THOSE WHO SHOULD GROW MUSHROOMS.

=Market Gardeners.=--The mushroom is a highly prized article of food which can be as easily grown as many other vegetable products of the soil--and with as much pleasure and profit. Below it is shown, in particular, that this peculiar plant is singularly well adapted to the conditions that surround many cla.s.ses of persons, and by whom the mushroom might become a standard crop for home use, the city market, or both. It is directly in their line of business; is a winter crop, requiring their care when outdoor operations are at a standstill, and they can most conveniently attend to growing mushrooms. They have the manure needed for their other crops, and they may well use it first for a mushroom crop. After having borne a crop of mushrooms it is thoroughly rotted and in good condition for early spring crops; and for seed beds of tomatoes, lettuces, cabbages, cauliflowers, and other vegetables, it is the best kind of manure.

Years ago market gardening near New York in winter was carried on in rather a desultory way, and the supply of salads and other forced vegetables was limited and mostly raised in hotbeds and other frames, and prices ran high. But of recent years our markets in winter have been so liberally supplied from the Southern States, that, in order to save themselves, our market gardeners have been compelled to take up a fresh line in their business, and renounce the winter frames in favor of greenhouses, and grow crops which many of them did not handle before.

These greenhouses are mostly long, wide (eighteen to twenty feet), low, hip-roofed (30) structures. In most of them the salad beds are made upon the floor, and the pathways are sunken a little so as to give headroom in walking and working. Others of these greenhouses are built a little higher, and middle and side benches are erected within them, as in the case of florists' greenhouses, and with the view of growing salad plants on these benches as florists do carnations, and mushrooms under the benches. The mushrooms are protected from sunlight by a covering of light boards, or hay, or the s.p.a.ce under the benches is entirely shut in, cupboard fashion, with wooden shutters. The temperature is very favorable for mushrooms,--steady and moderately cool, and easily corrected by the covering-in of the beds; and the moisture of the atmosphere of a lettuce house is about right for mushrooms. In such a house the day temperature may run up, with sunshine, to 65 or 70 in winter, but an artificial night temperature of only 45 to 50 is maintained. Under these conditions, with the beds about fifteen inches thick, they should continue to yield a good crop of short-stemmed, stout mushrooms for two or three months, possibly longer.

Besides growing the mushrooms in greenhouses our market gardeners are very much in earnest in cultivating them in cellars. Some of these cellars are ordinary barn cellars, others--large and commodious--have been built under barns and greenhouses, purposely for the cultivation of mushrooms. Several of these mushroom cellars may be found on Long Island between Jamaica and Woodhaven.

=Florists.=--In midwinter the cut flower season is at its height and the florist endeavors to make all the money out of his greenhouses that he possibly can; every available inch of s.p.a.ce exposed to the light is occupied by growing plants, and under the benches alongside of the pathways dahlias, cannas, caladiums, and other tubers and bulbs are stored, also ivies, palms, succulents and the like. In order that the plants may be more fully exposed to the sunlight, they are grown on benches raised above the ground so as to bring them near to the gla.s.s; and the greenhouse seems to be full to overflowing. But right here we have the best kind of a mushroom house. The s.p.a.ce under the benches, which is nearly useless for other purposes, is admirably adapted for mushroom beds, and the warmth and moisture of the greenhouse are exceptionally congenial conditions for the cultivation of mushrooms.

Florists need the loam and manure anyway, and these are just as good for potting purposes--better for young stock--after having been used in the mushroom beds than they were before, so that the additional expense in connection with the crop is the labor in making the beds and the price of the sp.a.w.n. Mushrooms are not a bulky crop; they require no s.p.a.ce or care in summer, are easily grown, handled, and marketed, and there is always a demand for them at a good price. If the crop turns out well it is nearly all profit; if it is a complete failure very little is lost, and it must be a bad failure that will not yield enough to pay for its cost. Why should the florist confine himself to one crop at a time in the greenhouse when he may equally well have two crops in it at the same time, and both of them profitable? He can have his roses on the benches and mushrooms under the benches, and neither interferes with the other.

Let us take a very low estimate: In a greenhouse a hundred feet long make a five foot wide mushroom bed under the main bench; this will give 500 square feet of bed, and half a pound to the foot will give 250 pounds of mushrooms, which, sold at fifty cents a pound net, brings $125. This amount the florist would not have realized without growing the mushrooms.

=Private Gardeners.=--It is a part of their routine duty, and success in mushroom growing is as satisfactory to themselves as it is gratifying to their employers. Fresh mushrooms, like good fruit and handsome flowers, are a product of the garden that is always acceptable. One of the princ.i.p.al pleasures in having a large garden and keeping a gardener consists in being able to give to others a part of the choicest garden products.

In most pretentious gardens there is a regular mushroom house, and the growing of mushrooms is an easy matter; in others there is no such convenience, and the gardener has to trust to his own ingenuity where and how he is to grow the mushrooms. But so long as he has an abundance of fresh manure he can usually find a place in which to make the beds.

In the tool-shed, the potting-shed, the wood-shed, the stoke-hole, the fruit-room, the vegetable-cellar, or in some other out-building he can surely find a corner; or, handier still, convenient room under the greenhouse benches, where he can make some beds. Failing all of these he can start in August or September and make beds outside, as the London market gardeners do.

In fruit-forcing houses, especially early graperies, gardeners have a prejudice against growing any other plants than the grapevines lest red spiders, thrips, or mealy bugs are introduced with the plants, but in the case of mushrooms no such grounds are tenable. As the vines have yielded their fruit by midsummer and ripened their wood early so as to be ready for starting into growth again in December or January, the grapery is kept cool and ventilated in the fall and early winter, but this need not interfere with the mushroom crop. Box up the beds or make them in frames inside the grapery; the warm manure will afford the mushrooms heat enough until it is time to start the vines, when the increased temperature and moisture of the house will be in favor of the mushrooms because of the declining heat in the manure beds. The mushrooms have no deleterious effect whatever upon the vines, nor have the vines upon the mushrooms.

=Village People and Suburban Residents.=--Those who keep horses should, at least, grow mushrooms for their own family use and, if need be, for market as well. They are so easily raised, and they take up so little s.p.a.ce that they commend themselves particularly to those who have only a village or suburban lot, and, in fact, only a barn. And they are not a crop for which we have to make a great preparation and need a large quant.i.ty of manure. No matter how small the bed may be, it will bear mushrooms; and if we desire we can add to the bed week after week, as our store of manure increases, and in this way keep up a continuous succession of mushrooms. A bed may be made in the cow-house or horse-stable, the carriage-house, barn-cellar, woodshed, or house-cellar; or if we can not spare much room anywhere, make a bed in a big box and move it to where it will be least in the way. But the best place is, perhaps, the cellar. An empty stall in a horse-stable is a capital place, and not only affords room for a full bed on the floor, but for rack-beds as well.

=Farmers.=--No one can grow mushrooms better or more economically than the farmer. He has already the cellar-room, the fresh manure and the loam at home, and all he needs is some sp.a.w.n with which to plant the beds. Nothing is lost. The manure, after having been used in mushroom beds, is not exhausted of its fertility, but, instead, is well rotted and in a better condition to apply to the land than it was before being prepared for the mushroom crop. The farmer will not feel the little labor that it takes. There is no secret whatever connected with it, and skilled labor is unnecessary to make it successful. The commonest farm hand can do the work, which consists of turning the manure once every day or two for about three weeks, then building it into a bed and sp.a.w.ning and molding it. Nearly all the labor for the next ten or twelve weeks consists in maintaining an even temperature and gathering and marketing the crop.

Many women are searching for remunerative and pleasant employment upon the farm, and what can be more interesting, pleasant and profitable work for them than mushroom-growing? After the farmer makes up the mushroom bed his wife or daughter can attend to its management, with scarcely any tax upon her time, and without interfering with her other domestic duties. And it is clean work; there is nothing menial about it. No lady in the land would hesitate to pick the mushrooms in the open fields, how much less, then, should she hesitate to gather the fresh mushrooms from the clean beds in her own clean cellar? Mushrooms are a winter crop; they come when we need them most. The supply of eggs in the winter season is limited enough, and pin-money often proportionately short; but with an insatiable market demand for mushrooms all winter long, at good prices, no farmer's wife need care whether the hens lay eggs at Christmas or not. When mushroom-growing is intelligently conducted there is more money in it than in hens, and with less trouble.

CHAPTER II.

GROWING MUSHROOMS IN CELLARS.

=Underground Cellars.=--Mushrooms require a uniform moderately low temperature and moist atmosphere, and will not thrive where draughts, or sudden fluctuations of temperature or moisture prevail. Therefore an underground cellar is the best of all structures in which to grow mushrooms. The cellar is everybody's mushroom house.

Cellars are under dwellings, barns, and often under other out-buildings.

These cellars are imperative for domestic purposes, for storing apples, potatoes and other root crops and perishable produce; and for these uses we need to make them frost proof and dry. These cellars are ideal mushroom houses, and any one who has a good cellar can grow mushrooms in it. In fact, our market gardeners who are making money out of mushrooms find it pays them to excavate and build cellars expressly for growing mushrooms. Indeed, some of our market gardeners who have never grown a mushroom or seen one grown, but who know well that some of their neighbors are making money out of this business, instinctively feel that the first step in mushroom-growing is a cellar. It is almost incredible how secretly the market growers guard everything in connection with mushroom-growing from the outside world, and even from one another; in fact, in some cases their next-door neighbors and life-long intimate friends have never been inside their mushroom cellars.

If a cellar is to be wholly devoted to mushroom-growing it should be made as warm as possible with double windows, and double doors, where the entrance is from the outside, but if from another building single doors will suffice. A chimney-like shaft or shafts rising from the ceiling should be used as ventilators in winter, when we can not ventilate from doors or windows; indeed, side ventilation at anytime when the beds are in bearing condition is rather precarious. There should be some indoor way of getting into the cellar, as by a stairway from the building above it. Also an easy way of getting in fresh materials for the beds, and removing the exhausted material. This is, perhaps, best obtained by having a door that opens to the outside, or a moderately large one from the building above.

[Ill.u.s.tration: FIG. 1. MUSHROOM CELLAR UNDER A BARN.]

The interior arrangement of the cellar is a matter of choice with the grower, but the simplest way is to have beds three or four feet wide around the inside of the walls, and beds six feet wide, with pathways two, or two and one-half feet wide between them running parallel along the middle of the cellar. Above these floor-beds, shelf-beds in tiers of one, two, or three, according to the height of the cellar, may be formed, always leaving a s.p.a.ce of two and one-half or three feet between the bottom of one bed and the bottom of the next. This is very necessary, in order to admit of making and tending the beds and gathering the crop, and emptying the beds when they are exhausted.

Provision should also be made for the artificial heating of these cellars, and room given for the heating pipes wherever they are to run.

But wherever fire heat is used in heating these cellars, if practicable, the furnace itself should be boxed off, by a thin brick wall, from the main cellar, and the pipes only introduced. This does away with the dust and noxious gas, and modifies the parching heat.

But in a snug, warm cellar, artificial heat is not absolutely necessary.

We can grow capital crops of mushrooms in such a cellar without any furnace heat, simply by using a larger body of material in making the beds,--enough to maintain a steady warmth for a long time. But this, observe, is a waste of material, for no more mushrooms can be grown in a bed two feet thick than in one a foot thick. In an unheated cellar the mushrooms grow large and solid, but they do not come so quickly nor in such large numbers as in a heated one. And a little artificial warmth has the effect of dispelling that cold, raw, damp air peculiar to a pent-up cellar in winter, and purifies the atmosphere by a.s.sisting ventilation.

Instead of using box beds, some growers spread the bed all over the floor of the cellar, and leave no pathway whatever, stepping-boards or raised pathways being used instead. Of course, in these instances, no shelf beds are used. Others make ridge beds all over the cellar floor, as the Parisians do in the caves. The ridges are two feet wide at bottom, two feet high, and six or eight inches wide at top, and there is a foot alley between them. Here, again, no shelf beds are used.

One of the chief troubles with flat-roofed mushroom cellars is the drip from the condensed moisture rising from the beds, and this is more apparent in unheated than in heated cellars,--the wet gathers upon the ceiling and, having no slope to run off, drips down again. Oiled paper or calico strung along [Symbol: Inverted V] wise above the upper beds protects them perfectly; whatever falls upon the pa.s.sage-ways upon the floor does no harm.

In any other outhouse cellar, as well as in one completely given over to this use, we can make up beds and grow good mushrooms. Mr. James Vick told me that at his seed farm near Rochester he raises many mushrooms in winter in his potato cellars; and so can any one in similar places. Mr.

John Cullen, of South Bethlehem, Pa., a very successful cultivator, tells me that his present mushroom cellar used to be a large underground cistern, but with a little fixing, and opening a pa.s.sage-way to it from a neighboring cellar, he has converted it into an excellent cellar for mushrooms, and surely the immense crops that I have seen in that cave of total darkness justify his good opinion of it.

=In Dwelling House.=--The cellar of a dwelling house is a capital place for mushroom beds, and can be used in whole or part for this purpose. In the case of private families who wish to grow a few mushrooms only for their own use it is not necessary to devote a whole cellar to it; but part.i.tion off a part of it with boards and make the beds in this. Or make a bed alongside of the wall anywhere and box it in to protect it from cold and draughts, and mice and rats. You can have shelves above it for domestic purposes, just as you would in any other part of the cellar. Bear in mind that mushrooms thrive best in an atmospheric temperature of from 50 to 60, and if you can give them this in your house-cellar you ought to get plenty of good mushrooms. But if such a high temperature can not be maintained without impairing the usefulness of the cellar for other purposes, box up the beds tightly, and from the heat of the bed itself, when thus confined, there usually will be warmth enough for the mushrooms, but if not spread a piece of old carpet or matting over the boxing.

The beds may be made upon the floor, and flat, or ridged, or banked against the wall, ten or twelve inches deep in a warm cellar, and fifteen to twenty inches or more deep in a cool cellar, and about three feet wide and any length to suit.
