Avocado trees are vegetatively prolific.
The majority of the fruit then grows on the upper portion of the tree, making maintenance and harvesting more difficult and expensive. For several decades, the practice of pruning avocado trees was considered unacceptable in commercial orchards. In recent years, however, it has become apparent that opening up the tree canopy to light penetration is one of the ac-tivities most influential in increasing the fruitfulness of the tree. In addition, keeping the tree s height lower has been shown to facilitate ease of work and control harvesting costs. Opening the tree up to light penetration can be accomplished through pruning.
