Troubleshooting
Silver European Fan Palm problems — and how to fix them
Silver European 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.
Root rot
The primary killer, almost always caused by waterlogged soil or standing water; excellent drainage is non-negotiable.
Scale insects
Commonly found at the base of petioles and on frond undersides; treat with horticultural oil and remove affected material.
Frond die-back in wet winters
Cold combined with waterlogging is lethal; plant in a sheltered, well-drained position and protect container plants from winter rain.
Red palm weevil
An increasing threat in warm regions of the UK and Mediterranean Europe; monitor the crown for wilting and treat preventatively in affected areas.
Loss of silver colouring
Occurs in shade; maximum sun exposure is required to maintain the distinctive silver-blue frond colour.
