Troubleshooting
Nymphoides indica problems — and how to fix them
Nymphoides indica (Nymphoides indica) 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.
Cold damage
Collapses below about 10°C and is killed by frost. Lift the basket into a frost-free aquarium or tub over winter in temperate gardens.
Poor flowering in shade
It is a sun-lover; shaded plants make leaves but few snowflake blooms. Reposition into full sun.
Algae on leaves
Warm, nutrient-rich water encourages algal film. Avoid broadcasting fertiliser into the pond and add submerged oxygenators to compete with algae.
Plantlet overcrowding
Daughter plantlets form rapidly and can crowd the surface. Detach and thin them through summer to keep the clump open.
