With oak trees and more than a half-dozen fruit trees in our yard, we battle hungry squirrels for fruit every year. Nature won while we slowly developed a design to protect our fruit trees from the ravages of squirrels. This year we were finally successful.
We like eating fruits and vegetables, but oak trees simply have squirrels. Our Santa Clara Valley has an amazing climate for growing fruits and vegetables. “Until the 1960s it was the largest fruit production and packing region in the world with 39 canneries.”
Over the years we tried several designs, improving them by trial and error. This year’s design uses a PVC frame to suspend a plastic net around the fruit tree, where the net is tied several feet off the ground. In earlier designs the net went to the ground, but squirrels always found a way in.
Here’s our fuyu persimmon tree surrounded by the frame and net.
To build the frame and net,
- Construct a PVC frame around the tree. We use pipe and elbows.
- Drape a plastic net over the frame. The net needs to be long enough to drape to the ground on all sides. We use a 25′ x 25′ net.
- Gather the bottom of the net and tie it around the tree trunk, several feet off the ground.
- Roll the net between the tree trunk and a vertical leg of the frame, and bundle the rolled net. Repeat for all four corners.
This view of the net shows the four rolls radiating from the tree trunk, with the net hung off the ground so that squirrels can’t chew through the plastic net.
The design is flexible where the frame can be tailored to the size of the tree by using different lengths of pipe. During the winter, we disassemble the frame and roll up the net.
