Topic: Compost and Mulch, Trees
Title: Ground cover under trees from Austin
Answered by: Barbara Medford

QUESTION:

I need ground cover plants that can tolerate leaf litter and grow under oak tree shade.

ANSWER:

Not a whole lot of those around. Please read this previous Mr. Smarty question on allelopathy in oaks. Even those oak leaves on the ground have bad effects on other plants trying to grow there. Instead, we are fond of recommending a good quality compost or shredded bark mulch under that tree. It will combine with the oak leaves and gradually decompose to help amend the soil beneath in terms of drainage and access to the nutrients in the soil. It will have to be replaced from time to time, but that is still less expensive and work intensive than constantly replacing plants that will not survive. Also, the mulch, up to 4 inches thick, will provide a non-muddy path and protect the tree roots from heat and cold as well as retain our all-too-scarce moisture in the soil.
