Troubleshooting
Glaucous Lampranthus problems — and how to fix them
Glaucous Lampranthus (Lampranthus glaucus) 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.
Waterlogging and root rot
Clay or compacted soil causes root rot rapidly. Ensure planting in sharply drained, sandy substrate. Raised rockery positions or sloped banks are ideal. Avoid planting in low spots where water collects after rain.
Frost damage
Frost-tender; damaged by temperatures below about -2°C. In frost-prone areas, protect with horticultural fleece or grow in containers that can be moved to a frost-free greenhouse overwinter.
Non-flowering
If the plant does not bloom, the most likely cause is insufficient direct sunlight. Flowers are triggered by warmth and bright light; even partial shade significantly reduces flower production. Also check that plants are not being over-fed with nitrogen.
