Hi Denise,
to NGA
I'm looking forward to hearing more from you. It sounds like, with your background, you have a lot to add to NGA.
Black walnuts: That's a good question. My only thought is that the walnut is not big enough yet to cause problems but its only a matter of time. Every one of those plants should be unhappy so close to the walnut tree. You are minimizing the damage by keeping the leaves and nuts cleaned up but the root system is still down there doing its black walnut thing. Will your neighbor consider taking the tree down? Too bad they let it grow there in the first place.
