Question
Is there anything that even resembles grass that will grow with black walnut trees in the vicinity?  I reseeded our lawn 4 times before I stumbled upon black walnut toxicity information.  Help!!  I'm tired of looking at dirt.

The answer depends on where you live.  I can answer for zone 6 and further north.  Kentucky bluegrass grows underneath my black walnut just fine.  however, if you live in lower zone 6 or higher, you may have trouble with that grass.

In more southerly climes, I have no idea.  I have seen mixtures of grasses and "weeds" under these trees in the south, mostly in pasture settings.  You might try a pasture blend for your area to see what survives.  I would check with your local ag agent to see what is recommended for that use.

Best wishes.
