My Grass Has Flatlined

Well the easiest and one of the least expensive parts of my front yard (can you call it a yard with no grass?) redo is done. Now comes lots of digging, packing and placing 180 garden blocks, backfilling with dirt, planting plants, running a drip system and spreading 10 yards of bark/mulch. I actually already dug back the wall and dug holes for plants on the small 20 foot side on sunday. I can feel it in my back.
