We’ve been guilty in the past of claiming that growing fruit is labor-free. That’s a lazy blogger’s lie. The truth is that you have to stay on top of pruning, irrigation, fruit thinning, fertilizing and pest prevention if you want to harvest any fruit. After not getting a single peach off our small tree last year due to squirrels, I vowed to do things differently this year.
I considered a number of squirrel prevention techniques:
- Metal collars on trunks. This doesn’t work, especially in urban areas. Squirrels are superb acrobats and can simply jump from a roof, fence or adjacent tree on to your fruit tree.
- Trapping, killing, hunting. I don’t have the heart to do this and it’s illegal in urban areas but it is what professional orchardists do.
- Electronic or visual frightening devices. According to UC Davis, these don’t work. Squirrels aren’t dumb.
- Dogs. Maybe, but it depends on the dog. Our late doberman was more interested in alerting us to the mail carrier’s rounds. He was more interested but, ultimately, unsuccessful in his 13 year battle against skunks.
Exclusion with plastic bird netting is the most promising technique for urban areas. In order to do this you need to keep the tree pruned to a manageable size. I purchased a 14-foot by 14-foot piece of bird netting and Kelly and I put it on the tree (it’s a two-person job as bird netting is a pain to work with). We secured it with clothes pins. You must be absolutely certain to leave no gaps in the net. If you leave a gap you could trap birds and the squirrels will also work their way in. The next step is to keep a close eye on the fruit and harvest it as soon as you can, perhaps a little sooner than is ideal.
Unfortunately, squirrels can easily chew through bird netting so this method is far from foolproof. According to UC Davis, exclusionary methods will only work if the squirrels have other things to eat. Another argument for biodiversity in our landscapes, I suppose.
