A study of mushrooms and mushroom spawn

by Edward Henry Jacob

SPAWNING

The bricks of spawn should be broken into ten or twelve pieces and placed on the surface of the beds 8 to 10 inches apart each way. Then go over the bed again, raising the manure and burying the spawn about half-inch below the surface and tamping (pressing) firmly over each piece, leaving the bed level on top.

In about two weeks dig up a piece or two of spawn carefully, and if the mycelium is noticed running out like a mould from the brick into the manure it is time to case.

This is done by putting one inch of sifted soil evenly over the top of the manure.
