Nut trees can enhance the home landscape, produce delicious nuts and provide shade. When deciding what nut trees to grow in your yard, first determine if they are suitable for your hardiness zone or grow zone. Next, consider the tree's mature height and spread. Some nut trees, like the Hardy Almond, are easy to fit into a variety of landscape because they grow just 15-18 ft. tall. Other nut trees can grow 40 ft. or taller and need a larger yard to accommodate them. Other considerations when selecting nut trees for sale online are the trees' growth rate, habit or shape, sunlight requirements, pollination requirements and what types of nuts they produce.
