Choosing a Location to Grow Avocados

Avocados will grow in shady areas, but are productive only in full sun. The roots are highly agressive and competitive and they will choke out nearby plants. The shade under the trees is too dense to garden under, and the constant litter can be annoying. In cooler areas plant the tree where it will receive sun during the winter. Give the tree plenty of room–up to 20 feet. The avocado is not suitable for hedgerow, but two or three trees can be planted in a single large hole to save garden space and enhance pollination. At the beach or in windy inland canyons, provide a windbreak of some sort. Once established the avocado is a fairly tough tree. Indoor trees need low night temperatures to induce bloom. Container plants should be moved outdoors with care. Whitewashing the trunk or branches will prevent sunburn.

Soil

What type of soil is required to grow avocados? Avocado trees like loose, decomposed granite or sandy loam best. The trees will not survive in locations with very poor drainage. Pooled water near the roots will cause rotting and destroy the plants. The avocado trees grow exceptionallywell on hillsides. You should never plant them in stream beds. They are tolerant of acid or alkaline soil. In containers use a planting mix combined with topsoil. Plastic containers should be avoided, but will work if necessary. It is also useful to plant the tub with annual flowers to reduce excess soil moisture and temperature. Remember, the plants must have proper drainage in order to survive. Container plants will need to be leached often to reduce salts.

Irrigation

Will your Avocado Tree need irrigation? Avocado trees may not need irrigation during the winter rainy season, but watch for prolonged mid-winter dry spells. Over irrigation can induce root which is the most common cause of the plant to be unsuccessful. To test to see if irrigation is necessary, dig a hole 9 inches deep and test the soil by squeezing. If it is moist and the soil holds together, do not irrigate; if it crumbles in the hand, then we recommend that you water. Watch soil moisture carefully at the end of the irrigating season. Never enter winter with wet soil. Avocados tolerate some salts, though they will show leaf tip burn and stunting of leaves. Deep irrigation will leach salt accumulation.

Frost Protection

How to protect avocados from frost? It is important to choose a cultivar that is hardy in your area. Cold temperaures can damange and kill avocado trees. See the picture below to recognize avocado frost damage. Mexican types are the best choice for colder regions. Plant above a slope for air drainage, or near the house for added protection. In youth, protect with rugs, towels and such spread overhead on a frame. For further protection heat with light bulbs and wrap the trunk with sponge foam. These measures also permit tender cultivars to become established in borderline locations; established trees are much hardier than young ones. The upper branches can also be top worked with hardy Mexican types, which will protect a more tender cultivar on lower branches, as well as serving as a pollinator. Harvest fruit before the frost season begins. Cold-damaged fruit turns black. Avocados are often in bloom at the time of frost and the flowers are killed, but the tree tends to rebloom. This is especially tru of Mexican types.
