384 VEGETABLE FORCING 



small tomato plants might be greatly injured by setting 

 in beds of large lettuce, while large ones would be 

 damaged only slightly. 



Ideas and planting distances for greenhouse companion 

 cropping are so variable that it is impossible to present 

 definite plans which are standard in the culture of crops 

 under glass. It is hoped, however, that the following 

 will be suggestive to those who are interested in this 

 subject: 



1. Cauliflower (C), Lettuce (L).

Large, vigorous plants of cauliflower and lettuce set 

 at the same time. The lettuce should be harvested in 

 about five weeks. 



2. Same as No. 1, except rows of radishes are planted 

 between the solid rows of lettuce and the rows of lettuce 

 and cauliflower. Eleven or 12-inch spaces instead of 10 

 inches are desirable. 



3, Cauliflower (C), Radish (R).

Cauliflower plants 20 by 24 inches apart. Radish rows 

 4 inches apart. Less space may be allowed for cauli- 

 flower if desired. Radish seed sown in drills at the time 

 the cauliflower is planted. The radish seed is sometimes 

 sown broadcast instead of in drills.
