Great Ornamental Trees
Dogwoods are considered a popular ornamental tree among homeowners. The primary reasons include their four season appeal and modest size. When you understand some facts related to dogwoods, nurturing and growing these beautiful trees becomes easier. Most trees in the dogwood family have deciduous foliage.
The leaves of these trees are untoothed and simple. In most cases, they have opposite arrangement on the twigs. Flowers on these trees bloom in the early spring season. Often, this happens before you can see the leaves. Flowers are greenish and small. They are arranged in clusters around the twigs.
Sometimes, the flowers on these trees are surrounded by whitish leaves. These are modified as showy, petal-like bracts. This gives the impression of a large, single flower. The fruit of the tree is a drupe, i.e, a hard structure surrounded by edible pulp. There are many North American species of dogwood trees that achieve small size. Most homeowners prefer these species.
Most people don’t use the tall 43 feet specie available in North America. When it comes to landscaping, homeowners prefer the flowering dogwood. This is a very attractive specie often cultivated for its showy and large, white bracted flowers. They grow purple during the autumn season in clusters.

On the other hand, the pagoda dogwood is also commonly found in eastern United States. However, it’s growth extends up to easter Canada.
Another popular specie of the tree is kousa dogwood. It’s native to Asia, especially Japan, China and Korea. Red twig dogwood is commonly found in Siberia, and red osier dogwood is found in parts of Canada and Pacific Northwest.
Sunlight & Soil
Like other flowering trees, dogwoods need ample sunlight to bloom. Though most species can bloom in shade, most grow well in sunlight. This is true of the red twig and flowering dogwood varieties. However, you should never compromise soil for sun.
Dogwood trees don’t grow in dry, hot ground. When you have to choose between sunlight and soil, you should choose moist, cool soil over sunlight. These trees can even grow well in partial sunlight. The soil should be acidic and slightly rich in organic matter.
Other Important Considerations
Most homeowners prefer dogwoods for their backyards. They are considered beneficial due to their ability to grow in a naturally pleasing shape. Moreover, these trees don’t require pruning. They can sometimes be bothered by anthracnose, which can cause various spots to appear on the tree’s leaves. It can also cause canker, powdery mildew and some other fungal and bacterial diseases. Insects pests can also infest these trees. Some of these include aphids, thrips and scale.
