Growing Walnut Trees In The Landscape
Walnut trees are treasures that add grace and beauty to the landscape. Walnut trees produce not only a delicious, nutritious nut but are used for their wood for fine furniture. Most growing walnut trees attain heights of 50 feet with an equivalent width and can be found throughout the United States. The English or Persian and black walnuts are the most common, used for nut production as well as shade trees. A mature tree will produce 50 to 80 pounds of nuts yearly. Growing walnut trees require 140 to 150 days with temperatures over 27 to 29 F. (-2 to -6 C.) for the earliest ripening varieties. Once you have made your selection, it’s now time for planting the walnut tree. Till a 12 square foot area down to the depth of at least 10 inches to remove any grass, weeds or other plants that compete for the new trees water and nutrients.
Then, dig a hole 1 to 2 inches larger than the walnut seedling’s root ball. Put the seedling in the hole to the same depth as the pot or bury the roots 1 to 2 inches below the soil. Fill in the hole and tamp down to eliminate any air pocket around the roots. Water the trees in until moist, not soaked. Mulch the surrounding area with organic mulch, like wood chips, bark or sawdust, to retard weeds and maintain moisture. Keep the mulch 2 inches away from your new trees.
