We have a grapevine growing on the neighbors fence (they don't take care of it) and it has tons of tiny grape bunches but they have started to turn fluffy and smell like somebody is spraying bug killer or something on them. It is very strong and I can even smell it in our house. Nobody ever eats the grapes, it always does really well since i take care of it the best I can but I have my own to baby and afraid it will affect mine. Does anybody know what is going on and what we should do? It's a very mature vine.
Thanks,
Holly
