Avoid over pruning If necessary, boxwood and yews can be lightly pruned to maintain geometric form. Avoid over pruning, especially in very sunny, hot weather.
Deadhead Continue to deadhead roses by cutting flowers back to the first set of five leaflets.
Monitor rose bushes for fungus Monitor roses closely for blackspot. Remove any leaves that show darkened circles with fuzzy margins on either the topside or underside of leaves; yellow foliage with dark spots; and any leaves that have already dropped from the plant. Begin a spray program with approved fungicides immediately. Always choose disease-resistant roses in the future.
