Well,that's a good idea, and if it were my own
flower beds, that's what I'd try. However, I'm landscaping and gardening for a client and these beds are pretty huge, and have to be weeded, mulched, fertilized, etc. regularly.
What I'm looking for are
plants that are sturdy enough to withstand 15 or 16 cats running over them and using them as litter boxes and maybe bushes (dwarf) that
flower in these shaded areas. I'm just about to give up. Thanks for your idea though. I might do that in the smaller areas.
