Red Indian Water Lily problems — and how to fix them
Red Indian Water Lily (Nymphaea rubra) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bud and pad damage from cold water
Cold water causes buds to abort and pads to develop poorly; dark-lined pots and pond positioning in full sun help raise water temperature. In UK climates, reliable blooming requires a heated pond or heated glasshouse.
Water lily leaf spot (Ramularia nymphaearum)
Brown or black spots with yellow halos appear on the upper surface of pads, leading to decay. Remove and dispose of affected pads promptly; improve water circulation and avoid overcrowding.
