Dogwoods bear delicate pink or white flowers made out of four petals each. The branches curve and twist, creating an interesting silhouette, and the tree itself does not grow tall. You can buy hardy, healthy varieties of these trees at nurseries in the eastern United States. One interesting way to plant these trees is to put one pink and one white dogwood together that will grow into one.
Find a spot for the trees that is partially, if not fully in the shade. Dogwoods do better in shady areas and are typically found under taller trees in nature. The best soil is a rich, well-drained one.
Dig a hole for the trees' roots. Make sure that the hole is big enough for the root systems of both trees to fit completely. The depth should put the tree base at the same level to the surface that is was in the pot.
Mix mulch in with the soil to add nutrients. Dogwoods love slightly acidic earth. The mulch will add this as it breaks down.
Sit the dogwoods in the hole and turn them so that the trunks are as close as possible. As the trees grow, the trunks will get larger, and possibly grow together, making the two trees look like one.
Pack the soil back around the trees and in between the roots so there aren't any air pockets. Cover the top of the soil with mulch to retain water and add more nutrients over time.
Water thoroughly after planting and then keep the soil around the two dogwoods moist to establish the roots. Check that the soil is getting damp down to about 6 inches.
