Recommended Spacing and Arrangement 
The recommended spacing is to plant 2 rows of Chinese 
Elm, Laurel Leaf Willow or Golden Willow on the out- 
side to form a snowbreak. Plant 4 feet apart in the row 
and 8 feet between rows. 
Leave 60 feet for a snow trap, then plant 4 rows of 
Green Ash, Chinese Elm, American Elm, Norway Poplar, 
or Soft Maple spaced 6 feet apart in the row and 8 feet 
between rows. 
Inside, plant 4 rows of evergreens 8 to 10 feet apart in 


NORWAY POPLAR THREE YEARS AFTER PLANTING 
Norway Poplar is one of our most rapid and hardiest windbreak trees. It will 
grow on any soil, and begins giving windbreak protection the second year after 
planting. For quick effect, include in your windbreak planting this spring, two or 
three rows of Norway Poplar. Planted in a shelterbelt or windbreak it is one of the 
quickest sources of fence posts and soft-wood lumber. To get quick results and 
to keep the snow away from the buildings include some Norway Poplar in your 
planting this spring. 
Instructions for Planting 
The soil in the space to be planted should be well prepared, as you would for any 
farm crop. Plant trees as early in spring as possible. Potatoes or vegetables may be 
planted between the tree rows for two or three years. Cultivate trees as often as 
possible in the spring and summer but not after the first of August. The snow trap 
may be planted to corn, potatoes, or any farm crop. 
Evergreens in sizes marked TR (transplanted) may be set out directly into the 
windbreak row and cultivated as you would rows of corn. 

the row and 16 feet between rows. The inside row of evergreens should be 100 feet 
from the farm buildings. This space and the snow trap give ample space to drop the 
snow and leave the buildings and yards free from drifts. 
For solid woodlot planting, set trees 8 to 9 feet apart each way. Ash, Elm, Nor- 
way Poplar, and Black Walnut are especially recommended for woodlot planting.
