If you have an avocado tree that is so rife with fruit, the limbs are in danger of breaking. This may lead you to wonder, “Should I thin my avocado fruit?” Avocado fruit thinning is similar to thinning other fruiting trees, such as apples. Removing avocado fruit may or may not be a good idea, it all depends on how and when you go about thinning the avocado fruit. So how do you thin avocado fruit? Read on to learn more.

About Avocado Fruit Thinning

Columnar cultivars of avocado are pinched at an early age to attain a more rounded habit, but most other types of avocado require no training and little pruning. Any pruning of avocado that may be done is done so judiciously since avocado trees are susceptible to sunscald, which results in defoliation. Avocado fruit is also self-thinning, so thinning avocado fruit is generally not required.

Should I Thin My Avocadoes?

While thinning isn’t normally required, several cultivars of avocado are in the habit of bearing fruit in alternate years. That is, in a particular year, the tree produces a staggering amount of fruit, so much that the energy from the tree either cannot support the enormous quantity or the resulting yield is high but fruit is small. In the following year, the tree’s energy is so depleted that it barely fruits, if at all.

In this case, it may be advisable to lightly thin the fruit. Also, thinning is advisable when multiple trees begin to grow together such that their canopies begin to lose light.

How to Thin Avocado Fruit

When trees are bearing overly heavily, they often drop a lot of fruit before it reaches maturity and any fruit that is left behind is often of a small size. Removing some avocado fruit will allow the tree to expend energy on the remaining avocadoes, resulting in larger fruit.

Avocado fruit is borne in clusters, sometimes just a few and sometimes many fruit are growing together. Take a good look at the grouping of immature fruit and identify any that are misshapen, diseased or pest damaged, and the smallest fruit. These are the fruit you will remove, leaving just the largest, healthiest looking avocado in the cluster.

Using sharp bypass pruners, snip off the immature fruit at the stem. I know it’s hard, but continue in this way until you have evenly spaced fruit on the tree. Space fruit about 6 inches (15 cm.) apart on the tree. If you have a cluster of fruit very close to the one that has just been thinned, it is best to remove it rather than thinning to one fruit.
