TREES FOR WINDBREAKS AND HEDGES 
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 develop a good root system so they can be successfully trans- 
planted bare rooted if handled with reasonable care to prevent drying 
which would be fatal to them. The supply of windbreak trees is very 
limited and the larger trees will not be plentiful for a number of years. 
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 prepared to load the trees directly into his truck from the field. 
SPACING. For single row windbreaks plant Pines and Spruces 7 
to 8 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 
particular 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 
frequent 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 ef- 
fective, 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. 
PINE—Ponderosa. Bull Pine. 50-60 ft. Very long coarse leaves and 
stiff rugged branches not easily broken. Endures extreme drought. 
Requires full sun and tolerates no shade.

White Pine. 70-80 ft. In spite of some breakage at times from heavy 
loads of ice, and that an occasional spraying may be needed to protect 
it from insect pests, we still think White Pine is one of the best of all 
windbreak trees. On a suitable soil and location it makes a very long 
lived beautiful tree retaining its branches to the ground. Do not 
plant it where drainage is poor nor on soil too rich from sometime 
having been a feed lot or having the drainage from one across it,
