How to Care For California Grown Walnut Trees Not only do walnut trees give us a nutritious and delicious nut, but they are also known for producing high quality wood. They are beautiful trees that provide a lot of shade thanks to their large, arching branches. How Walnut Trees Are Grown Many walnut trees that can be found growing in the United States attain a height of over 50 feet, with similarity in width. Most commonly, the varieties to be found in the United States are the Persian and English black, which provide nuts and shade. 50 to 80 pounds of nuts is the average annual production capacity of a mature tree. Prized for producing large nuts, the Persian walnut is the most common California grown walnut tree. Several cultivars exist, including Chandler, Ashley, Pedro, Howard, Hartley, Serr Vina, Tehama and Sunland. To avoid the walnut blight, all these cultivars leaf out late in spring. Persian walnuts have evolved to survive in Mediterranean climates that have mild winters, which means they may not be suitable in some regions. Between 140 and 150 days annually are required where the temperature ranges from -2 to -6 C (27 and 29 F) to successfully grow walnuts.

Planting Walnut Trees
Study: My Understanding of Resources
After choosing the type of walnut, it is time to plant the tree. To avoid competition for water and nutrients with weeds, grass and other plants, till approximately 12 square feet up to a depth of about 10 inches. Dig a hole roughly 1 or 2 inches wider than your seedling’s root ball. Plant the walnut seedling up to the same depth as its pot or bury its roots 1 to 2 inches underneath the soil. After you fill in the hole, you should tamp down to ensure that there are no air pockets left around the seedling’s roots. Next, water the walnut plant, moistening the soil without soaking it. Care for Walnut Trees Because of their extensive root system, walnut trees do not need constant watering unless the soil’s top 2 inches are dried out. A maturing walnut tree does not require any pruning unless its branches are damaged or dead. Every spring, remember to mulch the walnut tree. Harvesting Your Walnuts It is essential to be patient. This is because the walnut trees will not produce any nuts until they are roughly 10 years and production peaks at about 30 years of age. What are the signs that the walnuts are ready for harvest? A light tan color tells you that Persian walnuts are ready to be harvested. Commercial walnut producers shake the tree with a limb shaker which has a window to collect the nuts depending on how large a walnut tree is. However, a home grower can simply shake the tree branches and collect fallen nuts.
