SPRAYING DON'TS 



Don't wait for rose pests — spray first. 



Don't destroy toads or birds; they save you lots of trouble with insects. 



Don't mix spray materials unless you are a chemist. 



Don't use liquid sprays without keeping a uniform solution by means of 



agitating the liquid. 

 Don't whitewash your tree trunks; bugs are not afraid of whitewash. 

 Don't band tree trunks with anything but a preparation and at a time 



approved by an entomologist. 

 Don't spray exhibition plants or flowers with a discolouring spray. 

 Don't neglect to watch the wind when spraying; it may blow poison 



into someone's face and eyes or over a painted or varnished surface 



or scatter poison over food crops, like lettuce. 

 Don't dust your evergreens, coniferous or broad-leaved, with lime; 



the result will be more serious than any disease. 

 Don't be bashful about asking your State Experiment Station for help. 



Shrubs — Cultivation. The cultivation of shrubs is rather over- 

 done than underdone. The natural habitat of most woody plants 

 includes a ground covering of leaves, forest mold, or herbaceous plants 

 and grass; thus they are protected summer and winter against drought 

 and cold. It is not often possible to reproduce such conditions in a 

 made border; but the tendency should be in that direction. While a 

 certain amount of cultivation at first in a shrub border is desirable, 

 especially in new ground, most shrub borders would benefit by being 

 permanently mulched, or at least by not being dug over too deeply 

 after the roots of the shrubs have become established. The use of
