How and When to Thin Fruit

Timing around the June drop

Fruit trees naturally shed excess young fruit in early summer, often called the June drop. Do your planned hand-thinning straight after this drop, once you can see which fruits are sizing up.

How much to remove

• Leave about 4 to 6 inches between apples on a branch
• Keep one or two fruits per cluster
• Thin cooking apples harder than dessert apples for larger fruit
• Remove undersized, damaged, or crowded fruit first

Why thin

Hand-thinning promotes larger, better fruit and minimizes biennial bearing. Very heavy crops of small fruit one year can suppress flowering the following year.

✔ Thin within a few weeks of bloom for the most benefit; thinning much later mainly improves size rather than next year's crop.
