Deep shade, and maple roots: Help!
I have a crimson king maple in my front yard. Large heavy leaves, and the east is shaded by the house, and the west is shaded by oaks. I have a 18' circle bed under the maple with hostas, and "soon to be dead" other plants. I have killed alchemilla vulgaris "ladies mantle", pulmonaria "lungwort", and have Japanese painted ferns that are on year 3, but getting smaller each year. The bed is filled with excellent soil, and I water there more than anywhere else. but the solid mass of maple roots seem to be very daunting. Any ideas?
