THE VEGETABLE GARDEN 273 



Diseases and pests. Spray early with Bordeaux arse- 

 nate-of-lead mixture. Melons are subject to the attacks 

 of the same destructive insects and fungous diseases 

 as cucumbers and squashes. 



MUSTARD 



Mustard for salad may be grown on any kind of gar- 

 den soil. Sow the seeds thickly in drills six inches apart. 

 For spring use sow as early as the ground can be worked ; 

 freezing does not injure the seeds. A succession may be 

 had by sowing every two weeks. Sow in September for 

 fall salad or greens. For winter use it may be grown in 

 frames or boxes, where the cold can be partially excluded. 



To produce seeds for flavoring pickles and sauces, sow 

 in April, in rows one foot apart, and thin out to three 

 inches apart in the row when two inches high. 



ONIONS 



Varieties. Onions may be propagated from seeds, from 

 bulbs (commonly known as sets), and from top sets 

 (small bulbs formed on top of the flower stalk). Potato 

 onions and multipliers are compound sets, some of whose 

 parts may be planted ; they are valuable for spring 

 bunching. Perennial onions are hardy onions that may 

 remain in the ground from year to year ; they never form 

 large bulbs. Their special value lies in their providing 

 green onions for spring and fall use.
