Lasia spinosa problems — and how to fix them
Lasia spinosa (Lasia spinosa) 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.
Leaf browning from dryness
Letting the soil dry scorches and crisps the foliage; keep the roots permanently wet or standing in water.
Spines on stalks and rhizome
The petioles and rhizome bear sharp prickles; wear gloves when handling, dividing or harvesting the plant.
Cold damage
Frost and cold water kill or knock it back hard; overwinter in a frost-free, humid spot or treat as a tender summer plant.
Spreading habit
The creeping rhizome can colonise wet ground; contain it in a basket or defined bog area to limit its spread.
