Troubleshooting
Nymphaea 'Gonnere' problems — and how to fix them
Nymphaea 'Gonnere' (Nymphaea 'Gonnere') 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.
Few or no flowers
Almost always too little direct sun or planting too deep. Move to full-sun open water and ensure the crown sits no more than about 75 cm below the surface.
Yellowing leaves
Old pads naturally yellow and should be pinched off at the base; widespread yellowing signals nutrient depletion, so insert fresh aquatic fertiliser tablets.
Aphid infestation
Waterlily aphids cluster on pads and buds. Hose them off into the water for fish to eat, or submerge affected leaves; avoid chemical sprays that harm pond life.
Overcrowding and weak bloom
After a few seasons the rhizome congests the basket and flowering declines. Lift and divide in spring, replanting a healthy growing tip in fresh soil.
