Draining solution to prevent washing away of mulch?
One corner of our backyard has a downward pitch, probably 5% or so. The grass ends about halfway into the backyard, and is then all triple-shredded mulch. When it rains, lots and lots of runoff heads down to that corner, and is washing away not only the mulch, but the phlox and other things we've planted there. Not to mention that weeds have done pretty well, given the constant moisture. I haven't ever installed a French drain or similar, but am really in need of some help and would like to avoid calling a drainage specialist. Has anyone here had a similar issue that they were able to solve. Any and all guidance and suggestions are gratefully welcomed!!
