WINDBREAK EVERGREENS 
The trees offered in this section have not been sheared and have been 
grown in a thick row. They have been transplanted and root pruned to de- 
velop a good root system so they can be successfully transplanted bare root 
if handled with reasonable care to prevent drying which would be fatal 
to them. The supply of windbreak trees is very limited this year. 
We expect to under-cut these as soon as the frost is out, so a gang of three 
can get them out quite efficiently. If possible the buyer should come prepar- 
ed to load the trees directly into his truck from the field. 
SPACING. For single row windbreaks plant 8 to 10 feet apart; for double 
rows plant 10 to 12 feet apart in the row and space the rows still farther. 
SOILS. Pines prefer light, well drained soils, and White Pine in par- 
ticular is likely to be short-lived if planted in very rich soil such as an old 
feed lot or where the drainage from a feed lot or manure pile runs near them. 
In places where it is quite wet, Spruce will do better than Pine. 
PESTS. Red Spider or Mite causes much damage if there are not fre- 
quent dashing showers in early summer to destroy the young, and a rusty 
appearance is likely to be due to them. Water applied under a high pressure 
to the top every few days is an effective remedy. Pine Needle Scale is found 
almost everywhere and under favorable conditions may become a serious 
pest. White spots on the leaves of pine or spruce are likely due to it. Both 
this and Red Spider can be controlled by a single thorough spraying with 
Lime Sulphur such as orchardists use, in the regular dormant strength (1 to 
8 of water) applied on warm days in spring before the new growth starts. 
Soluble oil sprays also are effective, but must be used with much caution. 
With frequent dashing showers through June, when the young are crawling, 
neither of these pests is likely to be serious.
