Pot Marigold 'Pacific Beauty' problems — and how to fix them
Pot Marigold 'Pacific Beauty' (Calendula officinalis 'Pacific Beauty') 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.
Powdery mildew
White coating in humid, crowded conditions; space plants, improve airflow and water at the base rather than overhead.
Aphids
Calendula is a classic aphid magnet; blast with water, encourage ladybirds, or use insecticidal soap before colonies explode.
Heat-induced decline
Flowering stalls and plants look ragged in summer heat; cut back hard for a fresh autumn flush, or resow for cool seasons.
Self-seeding spread
Readily self-sows; deadhead or remove spent heads if you want to control where it returns next season.
