Considering the Soil

About soil condition, the cornus florida (flowering dogwood) does best in acidic, humus-rich, well-drained soils. It does not do well in overly wet or dry soils. If you have clay soil, mix in some sand and organic matter to improve drainage. Flowering dogwoods grow best in partial shade, but can tolerate full sun if given enough moisture.

About light

So, like the other plants, the cornus florida needs sunlight to grow. This means that it should be placed in an area that receives at least six hours of sunlight each day. If the plant does not get enough sunlight, it will not be able to produce the food it needs to survive.

Good Temperature

The temperature condition that is most favorable for the growth of Cornus florida is a temperature range of 65 to 75 degrees Fahrenheit. This plant does not tolerate temperatures below 60 degrees Fahrenheit well. In fact, if the temperature falls below 60 degrees Fahrenheit for an extended period of time, the plant will start to die.

Ideal Humidity

Ideal humidity condition for this plant is 50% to 60%. If the air is too dry, the leaves will turn brown and the flowers will drop prematurely. If the air is too moist, the leaves will develop powdery mildew.

The Fertilizer

For the fertilizer, this plant does best with a low nitrogen fertilizer. You can use a general purpose fertilizer or a slow release fertilizer. If you are using a liquid fertilizer, you only need to fertilize once a month. For the root, this plant prefers a well-draining soil. If you have a heavy clay soil, you can mix in some sand to help with drainage.

Light requirement

Pruning is important for keeping your cornus florida healthy and looking its best. Pruning can be done in late winter or early spring, before new growth begins. Cut back any dead or damaged branches, and remove any suckers that are growing from the base of the plant. You can also thin out the plant to allow more light and air to reach the center of the plant.

Plant Propagation

Propagation for the cornus florida, or flowering dogwood, is best done by softwood cuttings taken from young growth in late spring or early summer. The cuttings should be about 6 inches long and taken from healthy, disease-free plants. They should be cut just below a node, or leaf joint, and the bottom leaves should be removed. The cuttings can be planted in a propagating medium such as perlite, sand, or vermiculite, and kept moist until roots have formed. Once the roots are established, the cornus florida can be transplanted to its permanent location.

Growth Speed

Usually, the plant growth rate during the spring and early summer months. However, during the fall and winter, the growth rate begins to significantly slow down. The length of time that the cornus florida takes to fully mature can vary depending on the region in which it is growing, but it typically takes between 4 and 5 years.

The Problems
