Tree root barrier
I have several 3'x8' raised beds that are raised 2' off the ground. The neighbor's large spruce tree and small apple tree roots have taken over the beds and I need to dig them out and get rid of the roots.
Is there a tree root barrier that I can lay down on the bottom of the beds after I've dug them out that will stop the roots and not cause moisture? Any other ideas?
If there is a better forum for this question, please let me know.
Thanks from Sheryl
