%$#@!!! tell me about it. I had a 50’ x 100’ garden last year with green bean, yellow beans, heirloom beans, and soybeans (edamame) and the deer would just raze them down. Rats on hooves.
My brother is fighting that battle now and losing as you did. He is trying to feed them seed corn away from the garden. The only way it will stop is to fence it in.
Go easy on the edamame. I love them too but too much will make your wang shrink and give you man boobs.
There are some farmers where my GF lives that plant a few rows of soybeans around their corn to give the deer something else to eat besides the corn.
I know this sounds dumb but for protection of our beans it works.
Buy some of those small green fence posts and string some monofilament line between them about 3’ or so off the ground. You can space the posts at a fairly good distance. I use 50 # test fishing line but that is what I had.
When the deer approach, they feel the line but can’t see it and back off.
