Troubleshooting
Nymphaea 'James Brydon' problems — and how to fix them
Nymphaea 'James Brydon' (Nymphaea 'James Brydon') 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.
Pale flower colour
Crimson tones fade in heavy shade or cool seasons. Site for more direct sun to intensify the rosy-red and lift bloom numbers.
Waterlily aphids
Aphids colonise buds and young pads in warm spells. Knock them into the water with a hose jet for fish, and avoid oil sprays that coat the leaf and impede gas exchange.
China-mark moth damage
Larvae chew arcs from the pad margins and hide in folded leaf fragments. Remove damaged leaves by hand; worst in still, warm late-summer water.
Sparse, small pads
A congested rhizome or tired compost yields fewer, smaller leaves. Lift and divide every 3-4 years in spring, replanting a healthy growing tip in fresh aquatic loam.
