I live in an older established residential neighborhood. I have 6 neighbors that share my fenceline because of the size of my lot. My neighbor behind me put poison on my grape vine several years ago ( on my side of the fence) because she did not like it. The grapevine has probably been there for 40 years. I didn't say much then because I had just moved in. Today i go out to feed/water the chickens and turn the sprinkler on my garden. The grapevine is turning brown and it looks like it also got my squash and tomatoes on the first row next to the fence. I am soooooo angry. It is quite obvious the vine is mine and the garden is there. Not to mention my little girl, dogs and chickens play out there, too. I am so mad, I did not go over there yet because I am so mad. She is an older lady and I want to respect that, but this poisoning my garden. Any suggestions on how to handle this? My husband will be home soon and I am sure he is going to be even madder. He was so excited with our tomatoes and I think we could loose them all.
