Summer Pruning of Fruit Trees

Summer pruning of Stone Fruit Trees (apples, peaches, nectarines, plums, etc) is a proven technique for the home gardener. No longer do we have to let fruit trees reach 20 feet. Commercial orchards want big trees that they have a large crop for harvest. Smaller yards and a desire to have more fruit tree varieties lead us to use this method. You can maintain any tree at 7 to 10 feet with summer pruning.

SELECTION OF TREE:

We recommend you choose a Semi-Dwarf tree whenever possible. However, we have seen success with full-sized trees as well. Pick varieties with require only low chill hours. Most areas in the San Fernando Valley receive about 250-400 hours of chill below 45 degrees Fahrenheit. Since chilling is necessary for the production of fruit trees this is very important. There are LUCKY gardeners whose property contains a “micro climate” where the cold lasts longer and they may be successful with some of the older, longer chilling varieties, but if you are unsure, it is best to stick with low chill varieties.

LOCATION:

Full sun is best, however, you can expect some fruit even in partial shade areas. A minimum of six (6) hours is needed for fruiting.

WHEN TO PRUNE:

• First year trees should be cut back to 4 or 5 feet and a scaffolding made to support the fruit, preferably 3 or 4 branches. This may be done at planting.

• First pruning is done around April or May when the fruit is marble sized. At this time the fruit should be thinned. Cut off obvious dead branches, and branches that rub or criss-cross one another. Remove limbs with no fruit and space branches to allow the remaining fruit to grow. Thin fruit by spacing 3”-4” apart.

• Second Pruning is done during late summer, around September. Head the tops to the desired height, 7 ft, 8 ft, 9 ft … whatever you prefer. Cut off any dead branches.

• Repeat process the following April or May and each year thereafter.
