What do you put around the bottom of a tree?
The best ground cover is a thick layer of mulch around the base of the trees, which provides nutrients back into the soil, retains moisture, and helps moderate temperature. Spread a 2-4″ layer from the tree’s base out to the drip line, the point to which the branches extend. Choosing the Right Groundcovers for Landscaping Under Trees If you want to add greenery beneath your tree, go for shade-tolerant groundcovers with shallow roots that won’t compete heavily with the tree for water and nutrients. Some great options include Hosta, Ajuga, Pachysandra, and Ferns.
