Cavatine pieris problems — and how to fix them
Cavatine pieris (Pieris japonica 'Cavatine') 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 flower buds
Flower buds form in autumn and open in early spring, making them susceptible to late frosts. Site in a frost-sheltered position or protect with fleece during late cold snaps. The compact shape makes covering easy.
Lace bug
Stephanitis takeyai causes pale, stippled upper leaf surfaces and is more common in warm, dry, sunny conditions. Spray with insecticidal soap on the undersides of leaves in early summer, or apply a systemic insecticide.
Slow growth after planting
Cavatine is a naturally slow cultivar. Ensure optimal ericaceous soil conditions, consistent moisture, and shelter. Avoid disturbing the roots once planted. Growth rate improves significantly once the plant is established after 2–3 years.
