Sea Purslane Sun Rose problems — and how to fix them
Sea Purslane Sun Rose (Halimium halimifolium) 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.
Waterlogging and winter wet
Even brief periods of waterlogging in winter can trigger fatal root rot. In heavier soils or high-rainfall areas, plant into raised beds or mix in up to 50% grit and plant on a slight slope so water cannot pool around the crown.
Vine weevil larvae damage
Vine weevil (Otiorhynchus sulcatus) larvae can attack the roots of container-grown plants, causing sudden wilting and collapse. Use nematode biological controls (Steinernema kraussei, applied late summer to early autumn when soil is above 5 °C / 41 °F) as a preventive measure.
