Sea Heath problems — and how to fix them
Sea Heath (Frankenia laevis) 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.
Winter wet rot
The most common cause of death in cultivation is root and crown rot during wet winters; plant on a slight slope or in a raised bed with grit mulch around the crown to keep moisture away from the woody base.
Botrytis (grey mould)
Dense mats in still or humid conditions develop grey mould on dead leaf material; improve air circulation, remove dead growth promptly, and avoid overhead watering.
