Troubleshooting
Japanese Pieris Flamingo problems — and how to fix them
Japanese Pieris Flamingo (Pieris japonica 'Flamingo') 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.
Late frost damage to new growth
The vivid red emerging leaves are highly frost-sensitive; protect with horticultural fleece when sharp frosts are forecast in spring, or site against a sheltered wall.
Pieris lace bug (Stephanitis takeyai)
Causes mottled, silvery-white upper leaf surfaces; inspect the undersides for the dark excrement spots and tiny insects — treat with systemic insecticide or insecticidal soap in late spring.
Lime chlorosis
Yellow leaves with green veins indicate the soil pH is too high; apply sequestered iron as a foliar spray and acidify the root zone with sulphur chips or pine bark mulch.
