invasive tree roots
In my backyard I have tried to get many things to grow but nothing takes due to 2 silver maples. Last year, I put in a raised bed laying down two layers of landscape fabric, concrete blocks and sand as another barrier, then 12" of compost and soil. by the end of summer the roots had grown all the way through and choked the vegetables I tried to grow there.
Will anything grow there? The maples are about 12 feet away, the area gets 1/2 day of sun.
