I have about 10 acres of nearly solid RCG. It's a wet spot so it thrives. No haying equipment so it's already 6'+. You plow it over and it comes right back- it is incredibly deep and resiliant. I'm getting certified organic so don't want to use chemicals, plus all the neighbors have it so it would come right back. It's more of learning to live with it. Anyone dealing with this sort of thing? I'd like to hear about successes or failures. Thanks. I'm also curious- I plan to get someone in to hay it, but if I let it get really big will it kill buttercup and other weeds by choking? Will people want to hay a field that's 8' tall??
