I know they give my garden fits[well the tomatoes anyway]. You can't have tomatos near walnut trees. Just wont work. Now , I have a question. Can the roots of the walnuts kill off my golden seal too? I had an area just the other side of the walnut trees and it was going good for years. The last few it started to go down hill along about the same time the tomatoes would no longer tolerate the intrusion of the walnuts. Does anybody Know if thats why my patch that looked like a lawn now is about 20%.....

Most likely that is why your plants are dying. Walnuts are allelopathic, which means their roots produce chemicals that inhibit the growth of any other plant. It is a really cool competition method, but is horrible for plant you want to grow.

Cheers,

anybody have any experence or tips for planting seal? Got some time to fall plantings and want to get soil as ready as I can for a good crop. What about mixing in sand to the soil ? Roto till or just sort of for lack of better terms, insert into my plots?
