White Perfection Darley Dale heath problems — and how to fix them
White Perfection Darley Dale heath (Erica x darleyensis 'White Perfection') 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.
Phytophthora root rot
Caused by waterlogged conditions; plants collapse with yellowing foliage and black, rotted roots. Improve soil drainage before planting and avoid overhead watering. No chemical cure — remove infected plants and improve drainage before replanting.
Leggy habit without pruning
Failing to trim annually after flowering results in bare woody stems and loss of the compact mounding form. Clip over with garden shears immediately after the last flowers fade (typically May), removing spent flower stems but avoiding old wood.
Honey fungus (Armillaria)
Occasional susceptibility; indicated by rapid plant death and white mycelial fans under the bark at soil level. No treatment — remove stump and as many roots as possible. Avoid planting heathers near other susceptible woody plants.
