THE ALL-IMPORTANT factor in growing avocados is good drainage. Build a wide basin for watering. Let fallen leaves build up to provide mulch. Most roots are in the top 2 ft. of soil, so water lightly and frequently enough to keep that layer moist but not wet. Fast drainage is important. Give heavy irrigation every third or fourth time to wash out any excess accumulated salts. This will minimize salt burn. Following is a list of some of the most popular avocados grown in Southern California:
ALTHOUGH avocados are hardy to 20-24 degrees, flowers form in winter and temperatures much below freezing destroy the crop.
AVOCADOS tend to bear crops in cycles producing a heavy crop one year and a light crop the next.
WHEN using in landscape, remember that most varieties will grow 30 ft. and spread wider (tree size can be controlled by pruning.) Tree should have protection from winds. It drops leaves quite heavily all year. Wide-spreading branches with heavy foliage make dense shade beneath -- good garden area for potted plants that need shade. St. Augustine grass will grow beneath avocado trees.
IMPORTANT: When young (first 2-3 yrs) the bark and leaves are very sensitive to sun. It’s necessary to protect them. Use three 1’ x 6’ stakes with shade cloth between them.
