Growing your own nut trees can be so rewarding. Not only do they produce edible nuts, but they add beauty to the landscape and provide shade. Some nut trees commonly grown in the landscape are Hardy Pecans , Colossal Chestnut, Heartnuts and Hardy Almonds. When selecting nut trees to buy, first make sure they will grow in your grow zone. Next, consider their mature height and spread. One of the most popular nut trees for smaller spaces is the Hardy Almond. It grows 15-18 ft. tall. Other considerations when selecting nut trees are their pollination requirements, growth rate, sun and soil requirements, water requirements and what types of nuts they produce.
