FORCING 



to destroy these 

 pests before the 

 corn is planted. 



Another method 

 of forcing is that of 

 growing the sweet 

 corn in hotbeds or 

 cold frames. Here, 

 towards the end of 

 the hotbed season, 

 corn maybe plant- 

 ed in the hotbed. 

 Somegrowersprac- 

 tice the method of 

 growing a crop of lettuce in the hotbed, 

 following this by planting seeds of corn 

 and radishes at the same time. The rad- 

 ishes are matured and the corn is allowed 

 to develop. Generally speaking, the corn is 

 not planted so far in advance that, when it 

 is pushing the glass for room and the sash 

 must be removed, it may be injured by 

 frosts. In the cold frames it is often 

 possible to start the seeds quite early, 

 sometimes very nearly as early as started
