Good planting technique and quality after care are two factors necessary for success with Dogwood trees. In addition, you'll also need to keep these points in mind. Soils Dogwoods are adapted to a wide range of soils. However, they grow best in a well drained, fertile, loamy soil that is high in organic matter or humus. The desired soil is usually a long way from the typical heavy clay that is poorly drained, poorly aerated and almost completely lacking in humus or organic matter.
Dogwoods are native as understory trees in our pine and hardwood forests.
There they find plenty of humus and mulch. The most spectacular trees are usually found growing among tall, sparsely branched pines. Trees will also grow in hardwood shade of maples, oaks, hickories, but the amount of flowering is greatly reduced. If possible, select a location that gets some protection from the broiling sun of summer. Specifics about planting Even for the smallest tree, a good job of preparation starts with digging a hole 18 inches deep and 3 feet wide.
