ANDREWS Money Saving Shelter Belts 
Three-year-old windbreak at Madelia, Minn. Planted with Andrews’ fast-growing, hardy Ash 
Recommended Spacing and Arrangement 
The recommended spacing is to plant 2 rows of Chinese Elm or Golden Willow 
on the outside to form a snowbreak. Plant 4 feet apart in the row and 8 feet be- 
tween 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 the row and 16 feet be- 
tween rows. The inside row of evergreens should be 100 feet from the farm build- 
ings. 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, Norway 
Poplar, and Black Walnut are especially recommended for woodlot planting. 
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. Evergreens in sizes marked 
S (seedlings) should be set in the garden where you can give them special attention 
the first two years, then reset them into the permanent windbreak.

ASH. Most dependable of all trees for the wind- 
break or woodlot. Quick growing, long lived 
and excellent for lumber or fence posts. Will 
grow on almost any soil. Our strain of ash is a 
hardy Dakota strain that has proven to be 
drought resistant. 
AMERICAN ELM. Selected upland strain. Rec- 
ommended by the Conservation Department for 
shelter-belts and woodlots. Very hardy, long 
lived, beautiful. Wéill grow on almost any soil. 
Drought resistant. 
CHINESE ELM. Hardy Siberian strain. Grows 
rapidly even on poor soil. Low growing and 
dense branching habit makes our Siberian strain 
of Chinese Elm one of the very best windbreak 
trees to stop ground sweep of wind and drifting 
snow. 
SOFT MAPLE. Hardy, fast growing, especially 
on good soil. Gives almost immediate effect be- 
cause of its rapid growth and fine foliage. Some- 
times called Silver Maple. 
NORWAY POPLAR. Its hardiness together with 
its rapid growth make this variety outstanding 
for windbreak planting. Grows well on any soil. 
By including Norway Poplar in your windbreak 
or shelterbelt you will get windbreak protection 
several years ahead of plantings which do not 
include this variety. See photo, page 23. 
BLACK WALNUT. Grown from our native seed.. 
Good in the shelterbelt and the nuts are excellent 
for cooking. The lumber being of highest quality 
brings a good price on the market. 
RUSSIAN GOLDEN WILLOW. This fast grow- 
ing willow has attractive bright yellow bark. 
They are especially fine when planted in masses 
and are very colorful in winter. Hardy anywhere.
