I know how you feel! The hot humid weather takes it out of me really quickly. I have spent the last two weekends pulling weeds. Today, dodging raindrops, I got three bags of mulch spread over the bare spots. Got about four big trashcans full that will be picked up by city recycling. At first I was overwhelmed too, but just went out early and little by little I felt like I was making progress. Tonight looking out the window it makes me feel encouraged, the tide is turning. But my yard and beds are small so I can see progress quickly. Just pick one area and tackle that. Cooler weather will be coming soon which will make it easier for us all!
