Troubleshooting
H.E. Beale heather problems — and how to fix them
H.E. Beale heather (Calluna vulgaris 'H.E. Beale') 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.
Flopping or sprawling stems
'H.E. Beale' is taller than most heathers and can flop without support or adequate sun. Ensure full sun exposure. Trim lightly after flowering — but never into old bare wood — to maintain a more compact habit.
Chlorosis (iron deficiency)
Yellow foliage with green veins indicates alkaline soil or hard-water irrigation raising pH. Apply sequestered iron and switch to rainwater; test soil pH and acidify with sulphur if above 6.0.
Botrytis (grey mould) on spent flowers
In wet autumns, spent flower heads may develop grey mould. Trim off dead flowers promptly after the display ends and ensure good air circulation by not overcrowding plants.
