Allelopathy quiestion
I know walnut leaves are bad and can cause problems for a long time. I read somewhere coffee chaff is allelopathic but I can't find how long it might last. does anyone want to guess ? Or have a reference ?

I always compost coffee grounds, and add compost to my container mix and garden, and my plants do just fine. Here's an article from the Oregon State U. Extension Service: http://extension.oregonstate.edu/gardening/node/1009

I have never heard that but I add all of my coffee grounds to my compost pile as well as the occasional 5 lb. bag of grounds that I pick up at Starbucks.

I think black walnut is Allelopathic. But lots of plants and vegetable grow just under black walnut canopy with no problem. Only tomatoes died in my garden. We know that tomato plants are super sensitive to certain chemicals.

I am speaking about the light fluffy chaff that comes off the bean when it is roasted, not the grounds. The nutrient values are supposed to be about the same.

Well, Allelopathy normally refers to two different plants growing next to each other sharing some /same root zone. It is the chemical coming off of the roots that comes to play.
