How tall can an avocado tree grow?

An avocado tree can grow to about 20 meters tall. That is a maximum or potential height for a mature, naturally growing tree; cultivated orchard trees are often kept much shorter to make pruning, spraying, and harvesting easier.

The avocado, Persea americana, is an evergreen tree in the laurel family, which also includes plants such as cinnamon and bay laurel. It has a spreading form, greyish bark, and dense foliage. Its small flowers are produced in large clusters, and the tree’s height can vary with cultivar, climate, soil, rootstock, and pruning.

Commercial growers commonly use grafted trees and manage them at roughly 8–10 meters or less, even though an unmanaged tree may approach 20 meters. This is why photographs of compact avocado orchards can give the misleading impression that the species is naturally a small shrub. The familiar Hass avocado is a cultivar, not a separate species.
