Darley Dale Heath Furzey problems — and how to fix them
Darley Dale Heath Furzey (Erica x darleyensis 'Furzey') 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.
Dieback after hard winters without snow cover
Although hardy, prolonged frost combined with drying winds can desiccate shoots; fleece in the first winter after planting and site out of cold, drying east winds.
Lime chlorosis on very alkaline soils
Despite good lime tolerance, soils above pH 7.5 will cause yellowing; water with sequestered iron solution and mulch with composted pine bark to acidify gradually.
Aphid infestations on soft spring growth
The cream-flushed new growth in spring can attract aphid colonies; pinch out affected tips or treat with insecticidal soap — avoid systemic insecticides on flowering plants visited by pollinators.
