I planted a long line of White Dogwoods and Robinson Crabapples only a
foot and one-half away from a ditch. The ditch has a plastic pipe
covered by trap rock. The pipe carries runoff ground water to a catch
basin. WILL THE TREE ROOTS COMPROMISE THE DRAINAGE SYSTEM? The pipe is
no less than 20" deep. Our condo board needs assurance that all is
well, or I'll have to move all of the trees.
Thanks
