Calendula 'Indian Prince' (Calendula officinalis 'Indian Prince') 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.
Aphids
Gather on buds and shoot tips. Rinse off with water or treat with insecticidal soap; the plant also lures beneficial predators.
Powdery mildew
Less prone than some strains, but still possible late season or when crowded. Space plants and water at the base.
Flowering decline
Stops blooming once seed sets or in summer heat. Deadhead consistently to extend the long cool-season display.
Floppy stems
