Troubleshooting
Red morning glory problems — and how to fix them
Red morning glory (Ipomoea coccinea) 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.
Invasive reseeding
In warm climates (zones 9+) plants self-sow prolifically and can spread beyond the intended area. Deadhead spent flowers before seeds ripen, or pull seedlings early in spring.
Sparse flowering in rich soil
Excess fertility pushes leaf growth at the expense of blooms. This species actually performs better in lean, average soil with minimal fertilising.
Fungal leaf spots
Cercospora and other fungal leaf spots can appear in humid, wet seasons. Improve air circulation, water at soil level rather than overhead, and remove infected foliage promptly.
Prevent red morning glory problems before they start
Most red morning glory issues are care-mismatch, not bad luck. Dial in the basics:
