Black Locust Roots

Is there a major problem with black locust roots compromising a leech bed? If so, how safely can you plant a grove of black locust trees without causing major problems with the leech bed?

Answer

Ken,

I am not an expert on septic tanks and leech fields, but I can tell you that I don't think planting trees in the leech field is a good idea. Anything with a large root system could potentially cause problems, depending on how your system is configured.

On another note, I don't recommend planting black locust in any setting. It is a highly invasive, aggresive species that will take over the landscape. I spent over 3 years trying to eradicate if from highway corridors in the State of Maine. I can tell you from experience, once you plant it, it will be very difficult to control.

I hope this helps!
