Troubleshooting
Silver Mediterranean Fan Palm problems — and how to fix them
Silver Mediterranean Fan Palm (Chamaerops humilis var. argentea) 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.
Frost damage to fronds
Although the rhizome survives to -10°C, the fronds can be damaged by prolonged hard frosts or icy winds. Wrap the crown with horticultural fleece in very severe winters; damaged fronds can be cut back in spring as new growth emerges.
Root rot from waterlogging
Despite toughness, this palm cannot tolerate wet feet. Plant on a slight mound or in raised beds in heavy soils, and ensure container drainage is excellent. Yellowing and collapse of the centre indicate root rot.
Scale insects
Brown or white scale can colonise leaf bases and stems, especially on pot-grown specimens indoors. Treat with systemic insecticide or scrub off manually with soapy water and a soft brush.
