HOW TO GROW MUSHROOMS
Anyone who has a good cellar where an even temperature can be maintained can grow mushrooms for home use, but if they are to be raised in large quantities for market, an appropriate building must be given over to their exclusive use. We have been successful for several seasons in growing mushrooms in an amateurish way, but it was not until a large root-cellar was left vacant that we thought of the feasibility of adding them to our market products.
The farm we were lucky enough to acquire was one of the old-fashioned, practical places, with a full equipment of buildings. Under the cow-barn there was a stone basement, used for the winter storing of root crops. After our dairy herd developed, it seemed wise to use ensilage instead of roots during the winter. So we built a silo, and this left the store-house vacant. It was eighty feet long and fifteen feet wide, so, after we conceived the mushroom idea, we partitioned off thirty feet to retain as a storing-place for household vegetables and fitted up the other fifty feet with mushroom-beds.
We put in a brooder-house stove and pipe system, which cost one hundred and twenty dollars. The lumber for the beds cost an additional thirty dollars, extra manure twenty-two dollars and spawn fifty dollars—two hundred and twenty-two dollars in all. Four months later we had received four hundred and forty-five dollars. Since then the returns have fluctuated between four and five hundred dollars, and we estimate that it costs one hundred and twenty-five dollars per season to produce the crop. So I think that mushrooms can be considered profitable when run in connection with poultry or general farming, especially as they come in at a season of the year when there is very little else to be attended to, and, what is more, the only heavy work is preparing manure and compost for the beds, and that any ordinary farm man can accomplish. The rest is all so light and easy that a young girl or a delicate woman can attend to it without fatigue.
It is not necessary to have an expensive stone or brick building. We have a neighbour who uses part of an old cow-stable, and a man in the suburbs of New York, who grows a quantity each season, has simply a dugout with rough board walls, two feet above the ground, and an A-shaped roof—all covered with tar-paper, a place that could not have cost more than seventy-five dollars at the very most. A shed or outbuilding of any kind will answer if it is weather-proof and can be kept at a temperature of fifty-five or sixty in zero weather without much expense.
MUSHROOMS
Don’t be tempted to start on any elaborate scale in the house-cellar, for the odour from the beds whilst the manure is heating prior to planting-time will permeate the entire house and cling to carpets and draperies in a most horrible way. Of course, this does not obtain when only a few are to be raised for the home table, because shallow boxes can be used and need not be carried into the cellar until the objectionable period is past.
When a special house is used, the beds may be made on the floor, a great depth of manure used and artificial heat dispensed with. But it is not a good or economical plan, for the necessary amount of stable manure would cost as much as fuel, necessitate close watching and the result would not be as satisfactory, so we will only consider the approved method of benches and artificial heat, which is generally adopted by the modern market grower.
The benches in our house run on each side, leaving walks three feet wide through the centre of the house, two feet along the side walls. Having the three walks enables us to gather from each side of the beds, which is almost a necessity when the beds are four feet wide. With a narrower house and beds, a centre path would be sufficient, but it should not be less than three feet wide for convenience when filling and emptying beds.
