Size of a White Sapote Tree

Appearance

• White sapotes grown in ideal cultural conditions are more likely to reach heights closer to 60 feet. Canopy shape may be upright or spreading. The tree produces long branches from a thick, warty trunk. Branches are lined with palmate evergreen or semi-evergreen leaves and panicles of greenish-yellow flowers. Thin-skinned fruits contain creamy white or yellow fresh that is sweet and sometimes a little bitter near the seeds, which are bitter and toxic if ingested.

Location

• White sapote trees must be given ample space. Despite the trees' slow growth, their canopy and root system will eventually become extensive. The University of Florida Extension recommends planting the tree at least 25 feet away from nearby trees or structures, noting that crowded trees may grow abnormally or produce fewer fruits. The tree is hardy in U.S. Department of Agriculture plant hardiness zones 9b to 10, where it prefers full sunlight. Foliage damage will generally occur around 28 degrees Fahrenheit.

Culture

• White sapote prefers a well-draining soil with a pH between 5.5 and 7.5, but it is tolerant of a range of soils. To increase growth, apply 1/4 pound of a 6-6-6-2 fertilizer per 100 square feet after planting, once new growth appears. Apply every six to eight weeks for the tree's first year, then increase the amount of fertilizer to half a pound and then eventually one pound as the tree grows. Watch for snails, which can defoliate young trees and reduce vigor. Keep the area around the tree weed-free to lessen snail hiding places.

Pruning

• Pruning is helpful for a variety of reasons. Pruning the tree during its first two years will encourage lateral branching, while pruning older trees to a size of 10 to 15 feet will make them more manageable. Removing upper branches will allow more sunlight to penetrate lower branches, leading to increased fruit production. You may also need to prune branches that are located at crotches that are very horizontal or narrow, as these are prone to breaking. Pruning is best done in late fall, after fruits have been harvested. Enlist the help of a professional for trees over 30 feet tall.
