Roses suffer in the heat of August. Water deeply, mulch around the root zone to keep moisture in. With consistent care, roses should bloom again in the fall.
Cut back all hydrangea stalks that bloomed this year to 12 inches from soil level.
Clean up around fruit trees and pick any old fruit that could harbor soft rot fungus.
Plant a container of kitchen herbs on the patio next to the barbecue. Rosemary is great on beef or lamb and dill goes well with fish.
