SANITATION. 



Neatness, cleanliness, and order in the garden help in the fight 

 against insects and diseases. As a general rule, the residue of the 

 garden, such as cornstalks, potato tops, etc., are to be turned under 

 to improve the soil. Do this promptly, so that insects and disease 

 spores may not be harbored by the rubbish. In some cases, which 

 will be pointed out later, diseased vegetable remains should be taken 

 out of the garden and burned. Weeds in the garden and around 

 it harbor both insects and diseases, particularly if the weeds are 

 related to the cultivated plants. Plant-lice, red spiders, and other in- 

 sects invade the garden from 

 neighboring weed borders. 

 Cabbage pests live on wild 

 mustard, shepherd's-purse, 

 and related weeds. Just as 

 soon as any crop is gathered, 

 spade up the ground, bury the 

 old remains deeply, and plant 

 something else. Except in 

 the extreme North, rye or oats 

 can be sown to give winter 

 cover. 



CROP ROTATION. 



Farmers have found that by 

 rotating their crops they re- 

 duce the injury from plant 

 diseases and insects and also 

 increase the fertility of the 

 soil. This principle applies 

 to the home garden, where, if 

 possible, it will be better to 

 make a new plan each year, 

 placing each vegetable where 

 some other grew the year be- 

 fore — peas on the old tomato ground, beets and carrots after the 

 corn, etc. The details of this rotation must vary in each case accord- 

 ing to the climate, soil, and vegetables grown and the diseases and 

 insects to be guarded against.
