Avondale Redbud Tree Care

Overview

Redbud trees (Cercis chinensis) are desirable for their profusion of showy, bright-pink or deep purple spring blooms, as well as their compact size (around 10 to 20 feet tall, according to the University of Arizona) and attractive fall color. Avondale is a popular cultivar of this tree and one that is known for being an especially prolific bloomer, featuring purple flowers that coat the twigs and branches before any leaves uncurl. Care of the Avondale redbud tree is similar to that of other spring flowering trees, and as an added bonus, it is easy to transplant.

Climate

Avondale redbud trees are deciduous, temperate-region trees. They thrive in warm summers and mild winters. Avondale redbuds should be planted in United States Department of Agriculture (USDA) hardiness growing zones 6 through 9, according to information published by North Carolina State University.

Light

Cercis chinensis Avondale requires exposure to full sunlight in order to flower. Place it where it will receive at least six hours of sunlight. Eight to 12 hours of sunlight is even better, save for in the hottest regions of the recommended growing zone, where the tree can tolerate some dappled afternoon shade.

Soil and Water

Avondale can tolerate a wide range of soil conditions, according to North Carolina State University. It is tolerant of pollution and is often planted along city streets. The most important factor in the soil is that it should be well-drained, as young trees will tolerate even poor soil, but not very soggy soil, according to information published by Bartlett Tree Research Laboratories. Soil that is consistently wet will lead to root rot, a fungal disease of the roots. Water young redbud trees often enough to keep the soil moist, but not soggy, during the first year of growth. Established trees only need to be watered during periods of extended, hot drought, especially if planted where the tree receives full sunlight.

Pruning

These trees can be grown as either multi-stemmed shrubs or trained to grow on one trunk. Prune any branches that rub against each other, and thin out the canopy to prevent wind damage. Inspect the tree for broken or damaged branches early each spring, before buds appear, and remove those as well.

Problems

Redbud trees are susceptible to fungal diseases, according to Bartlett Tree Research Laboratories, and especially those that cause cankers, which are dead areas of wood. As the flow of nutrients is cut off to the branches, they begin to die from the tips inward, which is called "dieback." Prune off infected branches a few inches below the canker in order to prevent the spread of the disease. Watch also for boring and chewing insects, such as tent caterpillars, and treat the tree with an insecticide at the first sign of insect infestation.
