MUSHROOM GROWING 



freezing on mushroom beds which were 

 "well run." I refer to beds which hap- 

 pened to be spawned in November. The 

 spawn developed well for a month, then 

 from that time until about March the tem- 

 perature was never above 52*^ F. On sev- 

 eral occasions it was 32*^, or below, and the 

 beds were frozen. Continuously higher 

 temperature in March caused the beds to 

 bear abundantly, and the mushrooms were 

 of unusual size. The temperature was soon 

 above normal and the "life," that is, the 

 period of production of the bed was rela- 

 tively brief. Nevertheless, these beds pro- 

 duced heavy mushrooms much later in 

 the warm weather than beds which were 

 spawned in January, then held at a growing 

 temperature until the mushrooms appeared, 

 and finally subjected to the warmer condi- 

 tions above noted. 



The grower who wishes to produce heavy 

 mushrooms will do well to remember that 

 for this type it is not well to "push" the 

 beds by regulating to the highest permis-
