Troubleshooting
Pieris japonica Cavatine problems — and how to fix them
Pieris japonica Cavatine (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.
Lime-induced chlorosis
Yellow leaves with green veins mean the soil pH is too high. Switch to rainwater, feed with ericaceous fertiliser and apply sequestered iron.
Andromeda lacebug
Stippled, bleached upper leaves with rusty frass underneath signal lacebug, most severe on sun-stressed plants. Provide cooler dappled shade and treat infestations promptly.
Leaf scorch
Crispy brown margins result from drought, hot sun or wind exposure. Maintain consistent soil moisture, mulch well and site in shelter.
Root rot in pots
Waterlogged ericaceous compost suffocates roots, causing wilting and blackening. Use a free-draining mix and ensure containers drain freely.
