Dogwood
Dogwood is a genus of plants that consists of about 30–60 deciduous woody species native to the temperate Northern Hemisphere. There are several species of dogwoods commonly used as ornamental outdoor plants, including flowering dogwood, Cornus florida; pagoda dogwood, Cornus alternifolia; and kousa dogwood, Cornus kousa. Dogwoods are hardy in U.S. Department of Agriculture plant hardiness zones 5 through 9 and range in size from small trees to large shrubs, depending on species. Known for their spring blooms and attractive autumn fruit, dogwoods are easy-care plants once established in their desired location.
During the growing season, these plants need to be watered regularly, especially until established. Generally speaking, dogwoods need 1-2 inches of water per week. During hot, dry weather, more frequent watering may be necessary.
Dogwoods prefer part to full sun for most of the day, but will tolerate full shade. They do best in areas sheltered from strong winds and in slightly acidic soil.
Dogwoods prefer mild, temperate climates. In the United States, flower buds will be damaged by temperatures below -23°C (-10°F). They can tolerate temperatures as high as 38°C (100°F).
Dogwoods prefer moderately humid climates but can tolerate a certain amount of dryness. If grown in a low-humidity environment, extra attention must be paid to ensure the soil stays moist, as dogwoods can easily become drought-stressed.
Dogwoods prefer a soil that is light, well-draining, and slightly acidic. A combination of compost and soil works best. Additionally, if the soil is too alkaline the leaves may turn yellow.
Dogwoods should be fertilized in the spring and again in late summer. A liquid balanced fertilizer should be used in moderation, according to the manufacturer’s instructions. In addition to fertilizer, a layer of compost can also help provide nutrients to the soil.
Dogwoods are fairly resistant to most common pests, but can be prone to infestations of aphids, leaf miners, scales, and various caterpillars. The most common diseases affecting dogwoods are spot anthracnose and powdery mildew. If spotted early, these can usually be treated with fungicidal sprays. In cases of severe infestations, the affected parts of the plant may need to be removed.
Dogwoods should generally be repotted every two or three years. A good time to repot a dogwood is in early spring, before the buds start to appear. When repotting, make sure the root system fits snugly in the pot, and that the soil is enriched with compost or humus-rich fertilizer.
Dogwoods may occasionally need to be pruned to keep them in an attractive form. The best time for pruning is in the winter or early spring. Light pruning should be done throughout the year. Avoid pruning in the summer, as this can cause too much shock and stress to the plant.
Dogwoods should be mulched to conserve soil moisture and to provide nutrition. Organic compost, shredded bark, or grass clippings can be used. Make sure the mulch is spread evenly around the base of the plant, and keep it away from the trunk or stems.
Dogwoods can be propagated from either seed or cuttings. When propagating from seed, plant the seeds in a shallow tray and cover lightly with soil or compost. When propagating from cuttings, take a cutting from a healthy stem and place in a pot filled with potting mix. Keep the pot moist until the cutting has rooted.
In windy areas, dogwoods may need some support so that the branches aren’t damaged by the wind. Stakes or poles should be firmly anchored in the ground, and the dogwood should be tied to them securely.
Dogwoods do not require a dormant period, and may not respond to dormancy treatments. However, because these plants prefer moderate temperatures, they may benefit from a rest period during the hottest days of the summer.
Dogwoods are not toxic to pets.
