Troubleshooting
Trailing Iceplant problems — and how to fix them
Trailing Iceplant (Lampranthus spectabilis) 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.
Root rot
The primary threat, caused by waterlogged or poorly draining soil. Leaves become soft and mushy, and stems blacken at the base. Ensure sharply drained growing media and avoid overhead irrigation that pools around the crown.
Frost damage
Plants are damaged below about -2°C and killed by sustained frost. In frost-prone UK areas, lift plants before first frost and overwinter in a cool but frost-free greenhouse or conservatory.
Leggy growth and poor flowering
Caused by insufficient light or excessive nitrogen. Prune back hard after flowering to maintain compact shape and encourage bushy regrowth. Move container plants to the brightest available position.
