How to Grow and Care for Acacia

Acacias are graceful trees that grow in warm climates such as Hawaii, Mexico, and the southwestern United States. The foliage is typically bright green or bluish-green, and the small blooms may be creamy white, pale yellow, or bright yellow. Acacia may be evergreen or deciduous.

Most Аcacia tree types are fast growers, but they usually live only 20 to 30 years. Many varieties are valued for their long roots, which help stabilize the soil in areas threatened by erosion. The sturdy roots reach deep for underground water, which explains why the tree tolerates extreme drought conditions. Many types of Аcacia are protected by long, sharp thorns and an extremely unpleasant flavor that discourages animals from eating the leaves and bark.

Interestingly, stinging ants and Аcacia trees have a mutually beneficial relationship. Ants create cozy living quarters by hollowing out the thorns, then survive by eating the sweet nectar produced by the tree. In turn, the ants protect the tree by stinging any animals that attempt to munch on the leaves.

Growing Conditions and General Care

Acacia requires full sunlight and grows in nearly any type of soil, including sand, clay, or soil that is highly alkaline or acidic. Although Acacia prefers well-drained soil, it tolerates muddy soil for short periods.

Acacia is a plant-it-and-forget-it type of tree, although a young tree may need protection from wildlife while it develops its defense system.

During the first year, the tree benefits from an orchid fertilizer every three to four weeks. After that time, you can feed the tree a general-purpose fertilizer once every year, but it isn't an absolute requirement. Acacia requires little or no water.

Acacia may need occasional pruning during the dry months. Avoid pruning leafy, green areas, and trim only dead growth.

Although the tree is disease-resistant, it can sometimes be affected by a fungal disease known as anthracnose. Additionally, watch for pests such as aphids, thrips, mites, and scale.
