There are many types of dogwoods, ranging from small shrubs to single-trunked ornamental trees. Following is a list of some common types, some of which are American natives and others that come from Asia and Europe. Shrubs 3 to 5 feet tall and wide; trees from 10 to 25 feet tall with a trunk diameter of 6 to 12 inches.
Most dogwood shrubs and trees grow quickly, with a fast rate of over a foot a year. Trees will reach full size in about a decade. Like other deciduous trees and shrubs, the leaves of a dogwood are green during summer and change to an attractive reddish-purple during the fall, before dropping to the ground.
Deer resistance varies slightly between types, but for most, Rutgers rates them as seldom to occasionally damaged by deer. Plant with witch hazel , redbud and oakleaf hydrangea. Dogwood trees and shrubs have a naturally attractive shape, so they require little pruning unless needed for aesthetic reasons or to improve their vigor. The best time to prune is in the late winter when the tree is dormant to early spring, before new folige emerges.
Water your dogwood on a regular basis until it is established. Then, provide additional water during hot dry spells and mulch to help retain moisture.
Keep the mulch pulled back a few inches from the tree trunk. Dogwood trees prefer moist soils, with many tolerating boggy conditions, so they aren't necessarily drought tolerant. Be careful when fertilizing a young dogwood shrub or tree—many newly planted trees are killed by applying too much fertilizer.
For this reason it is often safest to hold off on fertilizing until your tree is in its second season. If you have an established dogwood that you feel would benefit from fertilization, have your soil tested to determine the best course of action. Additionally, fertilizer applied too late in the season can stimulate new growth that is vulnerable to winter damage.
Dogwoods are subject to anthracnose, a fungal disease that causes leaf spotting and twig dieback. Preventive measures include providing good air circulation to keep foliage dry, and watering in the summer during periods of drought. Any diseased twigs and branches should be pruned off. The ideal soil for growing a dogwood is a moist, loamy soil with a mildly acidic pH that does not have a high concentration of sand or clay.
Areas where there is standing water after a rain storm or where the soil remains saturated with water for days at a time usually cannot support a dogwood tree. The intensity of the sunlight where you plant your dogwood tree affects its growth and quality. Dogwoods that are grown on open ground under direct sunlight usually do not reach full size.
The best spot for a full-sized dogwood tree receives shade from a larger tree or a building for part of the day. Although dogwood trees can grow in areas that are deeply shaded throughout the entire day, too much shade discourages the tree from producing flowers. You can improve the growth of young dogwood using a fertilizer that provides nitrogen, phosphorous and potassium in a ratio of or Newly planted dogwoods, less than 2 feet tall, benefit from 1 tablespoon of fertilizer dissolved in water and spread around the base of the plant once early in the spring and again at the beginning of summer.
These trees are highly adaptable to a wide range of soils conditions, able to grow in clay and sandy soils. But they flourish in moist, loamy, slightly acidic soil. While they need to remain moist due to their shallow roots, they do not like having wet feet. During dry spells, you should water your tree at least twice a week—or more, if you live in an arid climate. Young white dogwoods do not require fertilization and can even die if too much is applied.
Wait until the second season of your tree to feed, using a small amount of slow-release, nitrogen-rich fertilizer with an NPK value of White dogwoods grow in a round shape, and do not need to be pruned to maintain it. If you decide to prune for aesthetic purposes, clip your tree in late fall or winter, when it is dormant.
If you see any dead, damaged, or diseased branches, you should prune them immediately. White dogwoods thrive when planted in well-drained soil in an area that receives partial shade.

Mulch should not cover the union as it will kill the tree. Make sure the hole is big enough to allow the roots to be spread out, at least 1 foot wider than the root spread.
Fill with same soil that came from hole-mix topsoil and subsoil together. Watch Arbor Day Foundation's video on how to plant bare root saplings. We recommend that you mark your planted tree with a flag or a protective tree sleeve examples here and here to protect your new tree until it becomes established.
Place a layer of inches of mulch around your newly planted trees, taking care to not pile the mulch too high on the trunk of the tree. You may fertilize your dogwoods at the time of planting and first watering, but do not fertilize again until the second year. Watering during winter is rarely necessary. In summer and fall, water once or twice a week. When watering, thoroughly soak root-zone area and beyond. After the first growing season, rainfall should be adequate except in times of drought.
Fertilize trees in the second year twice a year, in February and mid-June. Fertilize with 3 oz of nitrogen per sq feet of ground area surrounding tree, and water after fertilizing. Do not prune your dogwood until the second year. Plants should be pruned every years to maintain good shape. Avoid fall pruning because it will destroy the buds for the next year. Avoid pruning old, dried-up flowers.
Appalachian Spring is the only flowering dogwood resistant to dogwood anthracnose disease. Occasionally Appalachian Spring may be affected by powdery mildew, scale, borers, mites, or the Asian ambrosia beetle.
