Troubleshooting
Gold Haze heather problems — and how to fix them
Gold Haze heather (Calluna vulgaris 'Gold Haze') 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.
Foliage greening (colour loss)
Golden foliage reverts to green in shade, with high-nitrogen feeds, or when soil pH drifts above 6.0. Ensure full sun positioning, test and correct soil pH, and switch to a low-nitrogen ericaceous fertiliser. The golden colour is most vivid in full sun with cool temperatures.
Chlorosis from alkaline soil or water
Yellow foliage with green veins (iron deficiency chlorosis) occurs when pH rises above 6.0, locking out iron. Apply sequestered iron chelate as a drench, switch to rainwater irrigation, and lower pH with sulphur dust applied in autumn.
Woody, open centre after years of growth
Without annual trimming, the centre becomes woody and bare. Trim lightly with garden shears immediately after flowering each year, removing spent flower spikes and a small amount of the prior season's stems. Never cut back into old wood without live foliage — it will not regenerate.
