I don't have a garden, but large pots on a sizeable terrace in the middle of the city. One of the largest contains a gorgeous mature bay tree - and this year beautiful white clover started growing madly around it, in the pot! I love it, it looks fabulous , full of flowers and lush leaves, but the roots are getting quite thick and tangled, and I wonder if it might affect the tree?.... The pot is large, about 2 feet deep and equal width, so I am hoping that the clover can do its thing on the surface without hurting the tree roots below.
Any thoughts?
