Q

There is a pecan tree where I work that is dropping leaves like crazy. Can I add the leaves to my vegetable garden and let it compost over the winter? Is there any toxicity in pecan leaves?

Answer(s)

A

“Although pecans are related to black walnut, which secretes a compound that is deadly to tomatoes and some other garden plants, no evidence supports a cause for concern about using composted pecan leaves in the garden. Any toxic substances in pecan leaves or any other kinds of leaves that could injure garden plants are thoroughly leached out or broken down during composting.”
