Pruning

Master Gardeners teach pruning classes each spring. Learn how to prune apple trees and help maintain the orchard. Trained volunteers are also available to assist people at the pruning parties which will be held at 10 a.m. to 1 p.m. on the following Saturdays in 2022:

 

 

  • January 29  

  • February 12 & 26

  • March 5 & 19

People are welcome to prune at their convenience AFTER receiving appropriate instructions. Recommended pruning tools include work gloves, hand pruners, loppers and hand saws. Some tools available on site. Please carry all trimmings to the dumpsters.

 

Thinning – Saturday, June 4th, 10am – noon

Apple trees should be thinned when the fruit is approximately the size of a nickel. The fruit should NOT touch each other… remove all but one fruit per cluster. Gently twist off the excess fruit and dispose of in the dumpsters to avoid future insect problems. Join us on Saturday, June 4th, from 10 am – noon to thin or do at your own convenience.

Thinning is extremely important because it:

* Encourages larger, higher quality apples
* Prevents branches from snapping or breaking due to heavy fruit load
* Exposes developing fruit to sun so they can ripen fully and obtain good color
* Helps offset tendency for trees to “take a year off” after producing heavy fruit load

Pick Windfalls – Mid July – September

Pruning Adopters must pick up all windfalls and place the apples in the dumpster to prevent apple maggot larva from surviving in the soil and infecting future apple crops.
