Roses that have flowered should be pruned to promote reblooming and general health. Use hand pruners to remove flower clusters back to just above a lower leaf, and take out suckers and wayward stems. Any leaves showing signs of blackspot also should be removed. Wear thorn-proof gloves and a long-sleeved shirt.
