Troubleshooting
Pink Ice Plant problems — and how to fix them
Pink Ice Plant (Oscularia deltoides) 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.
Failure to flower
Usually caused by insufficient direct sunlight or over-fertilising with nitrogen. Move to the sunniest available position and switch to a high-potassium feed. Flowers open only in sunlight and close at night, so shaded plants appear not to bloom.
Stem rot at the base
Overwatering in winter or cool, damp conditions causes the woody stems to blacken and rot at the base. Cut back to healthy tissue, allow to dry, and treat with a fungicide. Improve drainage and reduce watering frequency.
Aphids on flower buds
Aphids cluster on new growth and flower stems in spring. Blast off with a strong jet of water or treat with insecticidal soap spray. Natural predators (ladybirds/ladybugs) help control populations outdoors.
Prevent pink ice plant problems before they start
Most pink ice plant issues are care-mismatch, not bad luck. Dial in the basics:
