Troubleshooting
Nelumbo lutea problems — and how to fix them
Nelumbo lutea (Nelumbo lutea) 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.
No flowers
Almost always too little sun or water too cold or too deep; give full sun and warm, shallow water and limit fertiliser to encourage blooms.
Invasive spread
Tubers run aggressively and can dominate a natural pond; grow in a submerged container or contained tub to keep it in bounds.
Aphids on flower stalks
Water-lily aphids cluster on buds and stems; dislodge with a hose or submerge affected stalks briefly rather than spraying near fish.
Tuber rot from cold
If the rhizome freezes it turns mushy and dies; in cold zones sink the container below the ice line or overwinter the tuber in damp, cool storage.
