Fossil records show that ginkgo trees, also known as maidenhair trees, have been on earth for over 150 million years. They grow slowly, reach heights of over 75 feet and have column-like trunks and fan-shaped leaves. Ginkgo trees are deciduous trees and grow in any soil type. Male specimens are recommended for the home grower due to the rancid odor of female specimens. The species is nearly impervious to disease and pests.
Choose a sunny location. Dig a hole that is twice as wide as the root ball. Set the soil next to the hole. The depth should be slightly shallower than the height of the root ball. Loosen the sides and bottom of the hole so that the roots can penetrate the ground.
Lay the tree and container on its side near the hole and tap the bucket to loosen the root ball. If the roots are wrapped in burlap, remove the wire or string and open the burlap. Line the hole with the burlap, which will decompose over time, adding nutrient value to the soil. Plastic wrapping must be removed completely.
Loosen the root ball gently. Remove extremely long roots to promote new growth. Spread the roots over the hole, guiding short roots down and out so that they make contact with the soil.
Fill the hole with the soil that was removed while digging. Leave an inch to an inch and a half of the crown (where the trunk and roots meet) exposed. Lightly tamp the soil down around the base of the tree.
Water the tree thoroughly. The soil around the tree should be soaked with water. Apply a 3-foot diameter of mulch around the base of the tree. Water it once a week during the growing season. Allow the soil to dry during the winter to prevent frost damage to the root tips.
Fertilize ginkgo trees twice a month from March until the end of July and again from September until the end of October. Use a standard tree fertilizer.
