Troubleshooting
Cinco de Mayo Rose problems — and how to fix them
Cinco de Mayo Rose (Rosa 'Cinco de Mayo') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Spider mites
Fine stippling and webbing on hot, dry, dusty plants; hose down foliage undersides and keep plants well watered to discourage them.
Aphids
Colonies on new buds and shoots in spring; wash off with water or use insecticidal soap before they cause distortion.
Spent-bloom clutter
Cluster flowers fade to a muddy look if left on; deadhead spent trusses to keep the plant tidy and encourage rapid rebloom.
Powdery mildew
Although resistant, it can show white mildew if roots dry out in humid air; water consistently and keep the centre open.
