Question: I have a large black walnut tree in my front yard. I was wondering if you could tell me what grasses would be able to tolerate the affects of juglone. I live on the south end of Blaine and have the typical sandy soil of the sand plain. The yard has both sun and shade.
Answer: As far as I know and have experienced, all the grasses are ok with juglone, the chemical from black walnut trees. Many monocots and the whole grass family seem to be immune to juglone, so I think you can try most any grass. A black walnut tree does not have much shade, that is a plus as well. Now you just have to deal with the tree root competition and dry site!! So I would try the drought tolerant grasses, such as blue grama, sideoats grama, little bluestem or prairie dropseed.
