I gave up on my garden by 1 August. Despite a fence, deep off, deer spray, and deer repellent canisters, the deer destroyed everything. Most of it in one afternoon while I was at work. I live in a forested area, and my garden was a semi cleared area. Only an 8’ fence would do it, and I am not going that far.
We have a frame of 2 inch pvc pipe around our raised beds plus bird netting. This is all it takes to keep critters out. This has worked for the three years we’ve assembled it.
