Mackay's Heath problems — and how to fix them
Mackay's Heath (Erica mackaiana) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Drought stress and root desiccation
Unlike most heaths, Mackay's heath has a low drought tolerance reflecting its bogland origin. Wilting, browning foliage, and plant death can result from dry soils, especially on sandy or free-draining sites. Mulch with composted bark and water regularly in dry periods.
Honey fungus (Armillaria)
Occasionally affects established plants, particularly those under stress; toadstools appear at the base in autumn and white mycelial sheets are visible under the bark at soil level. Remove and destroy affected plants and avoid replanting with susceptible species in the same spot.
