Troubleshooting
Mediterranean Fan Palm problems — and how to fix them
Mediterranean Fan Palm (Chamaerops humilis var. cerifera) 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.
Red spider mite
More prevalent in hot, dry summers; monitor undersides of fronds and treat with an appropriate miticide or neem oil.
Root rot from waterlogging
Even this tough species succumbs if the roots sit in standing water; always plant or pot with perfect drainage.
Frost damage to new fronds
Despite hardiness, emerging fronds in late spring are vulnerable to late frosts; protect with fleece if a frost is forecast.
Scale insects
Inspect the base of frond stalks; treat light infestations with cotton wool dipped in methylated spirit.
Yellowing older fronds
Normal ageing at the base of the canopy; remove only fully brown fronds to avoid fungal entry points.
