Part 6

After the soil is placed in the benches the bed may be immediately spawned; no waiting for temperature to go up or down. This work is done just as in spawning an old-fashioned bed, except that the spawn should be buried somewhat deeper, to guard against the surface drying of the soil during a hard day's sun on the glass.

Since the operation of a hothouse is a hard business proposition to the general grower, involving the question of the greatest production on the space at hand, it is advisable to get a crop growing on the benches as quickly as possible after the bed is spawned.

If some crop that will rapidly cover the surface of the bed is not planted immediately after spawning it is advisable to furnish some sort of a mulch to protect the soil from the direct rays of the sun. It is all the better to provide such a mulch even with the planted crop, filling in the unprotected spaces. Partially decayed leaves, fine salt hay, or any light, fluffy material will serve the purpose. Providing this mulch does not become soggy or heavy there is no necessity for removing it during the bearing season of the mushroom.

Should the regular bench crop, lettuce, for instance, be depended upon to furnish shade, some more or less accurate calculation should be made on having such crop on the beds so that it will protect the mushrooms when they first make their appearance.

There is one other condition upon which success is contingent, and that is in the proper watering of the soil or secondary crops. Water should be applied lightly and frequently with a spray nozzle, the object being to maintain sufficient moisture in the soil to supply the needs of the surface crop without soaking or flooding the soil to such a degree that it becomes unduly heavy or soggy.

In cultivating the surface crop the operator should not stir the soil to a greater depth than two inches, that the spawn may not be disturbed.

When the crops are cleared from the benches in the spring it is well to allow a dense mat of weeds to grow up to protect the mushrooms from the sun, which, otherwise, would "burn" or brown them.--_American Gardening._
