Nymphaea 'Albert Greenberg' problems — and how to fix them
Nymphaea 'Albert Greenberg' (Nymphaea 'Albert Greenberg') 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.
Sluggish start in cool water
Even this tolerant tropical needs warmth to get going. Plant out once the pond warms in early summer rather than in cold spring water.
Frost-tender crown
It will not survive a freezing winter outdoors. Lift the tuber before frost and store it warm and barely moist, or overwinter the plant under glass in heated water.
Aphids and leaf pests
Lush mottled foliage attracts waterlily aphids and china-mark moth larvae. Hose aphids into the water for fish and pick off rolled or mined leaves promptly.
Fewer flowers than expected
Normally very free-flowering, so a poor show points to shade, cool water or under-feeding. Provide full sun and warmth and feed every few weeks through summer.
