Here is what you can do with a mostly shady backyard. Get rid of the grass and make it a place to enjoy.
We removed all the grass, and after adding several tons of different rocks, the homeowner has a new yard. The overall desire was to keep it looking very natural. The 400 groundcovers, 86 perennials, 48 shrubs, and 1 tree will now need to grow and fill in the areas. In just a couple years, I will have to return to take photos of the area as it matures.
