Little Heath pieris problems — and how to fix them
Little Heath pieris (Pieris japonica 'Little Heath') 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.
Tip browning from wind or drought
The narrow white-edged leaves are especially prone to tip scorch in dry or exposed conditions. Shelter from prevailing winds and keep the root zone consistently moist, particularly for container specimens.
Reversion shoots
Occasionally produces plain green shoots without the white variegation. These should be cut out at the base immediately to prevent them from outcompeting the variegated growth.
Vine weevil in containers
Container-grown specimens are vulnerable to vine weevil grubs, which sever roots and cause sudden wilting. Apply nematode-based biological control (Steinernema kraussei) to moist compost in late summer.
