Troubleshooting
Wickwar Flame heather problems — and how to fix them
Wickwar Flame heather (Calluna vulgaris 'Wickwar Flame') 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.
Root rot / waterlogging
The most common killer of heathers. Ensure the planting site drains freely; raised beds or gritty soil amendments are essential in heavy clay gardens.
Straggly, open growth
Caused by insufficient light or failure to trim. Clip over lightly with shears immediately after flowering each year to maintain a compact, bushy habit. Do not cut back into old woody stems.
Yellowing foliage
Often indicates alkaline soil or iron chlorosis. Test soil pH and treat with sequestered iron if pH is above 6.0. Switch to ericaceous compost and avoid tap water in hard-water areas.
