Black WAlnut/juglone

Asked May 7, 2018, 6:45 PM EDT

I have bought a home in Trinidad with a huge black walnut tree. I’ve discovered that it puts out juglone, which is toxic to many plants. W hat can safely plant beneath it? The planting area is probably only 15’ x 30’, and I understand the roots extend 50’ to 80’.
