I have MS. Can still do most things, but generally only in short stretches. Fatigue comes on fast, along with weakness and numbness on the left side, especially in Summer. So the deep digging and moving bags of soil, mulch, and such I usually leave to whomever I can persuade to come help.
Most of the planting I do myself because that is the most fun for me. I'd be looking for ideas and tools to reduce energy expediture in order to maximize what I can get done.
