Can I safely spray cayenne soap deterrent on leaves?
Although I have only just started planting my orchard of peach, pear, plum, apricot, lemon, avocado, and nectarine trees, I know that I will be having a problem with 4-legged pests. With that in mind, we have fenced the whole area off with three-wire barbed wire, which really only deters cattle. There is deer-proof fencing around each tree. There are solid gopher cages at the base of each tree. I suspect the biggest threat now will be the robust community of California ground squirrels that live in the exact area where my orchard is.
Although I don't have high hopes for those homemade pepper spray concoctions (some of which recommend putting a bit of Murphy's oil soap in the mix) , I think we'll give that a try. My question is, can I spray that on the leaves, or does it hurt the foliage (partic young, sensitive foliage)? Can I spray it on the fruit (assuming, of course, that I will be washing the fruit before eating)? Any particularly effective recipes that someone would like to recommend wold also be much appreciated.
