Dogwood trees, and yellow flowered shrubs, among the most popular in the United States, provide an unrivaled display of beauty during all four seasons. The advent of the spectacular white or pink flowers, which are technically bracts and signal spring's arrival, is the primary draw for visitors. The dogwood's requirements for maintenance are simple, and it survives and expands rapidly in domestic landscapes despite its lack of attention.
There are many different kinds of dogwoods, ranging in size from low-growing shrubs to tall, attractive trees with a single trunk. The list that follows contains some of the most frequent varieties, some of which are indigenous to the United States, while others originate in Asia or Europe.
2-9, depending on the variety
Shrubs with a height of three to five feet and a width of one to two feet; trees with a height of ten to twenty-five feet and a trunk diameter of six to twelve inches.
Depending on the cultivar, the plant can tolerate either full sun or moderate or complete shade.
Bloom time is between the middle of March and the month of May, depending on the variety.
Most dogwood shrubs and trees develop rapidly, typically at a rate of more than one foot each year. Trees will reach their mature height and width in roughly a decade.
Bracts that resemble petals on dogwoods are typically white; however, some cultivars, such as C. Florida 'Rubra, have bracts that are pink or even a very light shade of red.
The leaves of dogwood, like those of other deciduous trees and shrubs, are green during the summer months but transform into an eye-catching shade of reddish-purple in the autumn before falling to the ground.
Trees have a circular shape and branch out in a horizontal pattern. Dogwood shrubs are known for their upright growth pattern.
Although the level of deer resistance varies slightly between varieties, Rutgers classifies most of them as rarely too infrequently harmed by deer.
Dogwoods should be planted in the spring while the earth is still moist and before the tree growing season begins.
Dogwoods can flourish in full sun or partial shade, making them an excellent choice for an understory tree or shrub.
Dogwoods are most successful when grown in soil that is mildly acidic, moderately acidic, well-drained, and contains organic matter.
Incorporate witch hazel, redbud, and oakleaf hydrangea into your planting.
Dogwood trees and shrubs already have a form pleasing to the eye, so they do not need much trimming unless it is necessary to enhance their appearance or increase their robustness. When the tree is passive in the late winter or early spring, which is before the new foliage grows, it is the ideal time to perform any necessary pruning.
Be sure to give your dogwood a consistent amount of water until it becomes established. Then, during very hot and dry spells, apply more water and mulch to assist in retaining moisture. Maintain a distance of several inches between the mulch and the tree's trunk. Dogwood trees aren't necessarily drought tolerant due to their preference for moist soils and their ability to tolerate marshy environments. Many dogwood trees can even thrive in these conditions.
Exercise caution when fertilizing a young dogwood shrub or tree because excessive fertilizer might kill the tree. This is the cause of death for many newly planted trees. Because of this, it is generally recommended to postpone fertilizing your tree until it has completed its second growing season. You should analyze your soil to discover the most effective method of fertilizing an established dogwood if you believe the tree might gain from adding nutrients. In addition, the fertilizer that is applied too late in the season might stimulate new growth that is more susceptible to damage during the winter months.
Dogwoods are susceptible to the fungal disease known as anthracnose, which spots the leaves and causes the twigs to die back. As a preventative precaution, you should ensure that the foliage has adequate air circulation so that it remains dry and water the plant during the summer months, even if there is a drought. It is essential to remove and cut away any infected twigs and branches.
The dogwood borer is the most frequent insect that causes damage to dogwood trees. Its larvae tunnel beneath the bark of the trunk and limbs. When performing lawn maintenance, take care not to cause any harm to the tree's bark; this is because freshly born larvae enter the tree through wounds or broken bark. Additionally, avoid pruning the tree from April to June, which is when borers are most active. Using a pesticide as a spray on infected trees is one treatment method.
You may buy various dogwood trees, bushes, and other dogwood-related products online. Depending on the size and type, you should anticipate paying anywhere from roughly $20 to $100 or perhaps more.
In spite of the fact that it is a relatively tiny tree, the dogwood's breathtaking beauty throughout the year has a significant impact on the appearance of residential gardens.
Blooms can be seen on trees and shrubs between the end of March and the middle of May, and they typically remain for three to four weeks at a time.
Flowers that grow on trees are more likely to be single and more prominent than other types of flowers.
Flowers on bushes are typically smaller and clustered together, as shown on the right.
After the blossoms fall off, the plant is covered in glossy green leaves, some of which have dramatic white or yellow variegation. Both trees and bushes have foliage that looks the same.
Berries come after the blossoms and serve as a food source for fall and winter by attracting birds. The hue of berries might differ from one type to the next.
Trees (left): Like the flowers, the berries that grow on trees are single and much more significant.
On shrubs (shown on the right): the flowers are followed by clusters of tiny berries.
Trees (left): After the leaves have fallen from the dogwood tree, the beautiful horizontal branches and scale-like bark become the focal point of attention. If you are fortunate, the crimson berries will remain on the tree throughout the winter, adding to the one-of-a-kind beauty of the textured bark.
Bushes (right): During the winter months, the stems of many dogwood shrubs take on an array of vibrant colors, including yellow, red, coral, and orange. (Depicted: dogwood from the Arctic Sun® brand)
Many states host festivals to celebrate the occurrence, some of which continue as long as a month, in anticipation of the dogwoods bursting into bloom each spring.
