The figure on the right shows the correct way to plant fruit trees. When planting a grafted tree, be sure that the graft union is 2 inches above the soil. If the graft union is below the soil surface, the top portion or scion will grow roots and negate the effect of the grafted root system. After the tree is in place, fill the hole with native soil, not potting soil. Adding organic matter or mulch to the soil can promote growth if these materials are mixed well with the soil.
Fertilizers are very caustic and can burn and kill the roots of young trees.
After you have filled the hole, be sure to water the area well. During shipping, handling, and planting, roots are damaged. After planting young trees, prune the top of each tree. Pruning the tree top balances the root system and promotes vigorous growth in the spring. When working with unbranched trees, cut the tree off approximately 32 inches above the ground.
