Containers overheat roots, inviting disease. Use potting mix (not garden soil), water well in heat, mulch tops. For mildew: spray 1 tbsp baking soda per 4 quarts water weekly. For black spot: remove heavily spotted leaves only; light spotting is tolerable. Hand-pick large insects; blast small ones with hose (shield canes).
