Chamaerops Humilis 'Vulcano' problems — and how to fix them
Chamaerops Humilis 'Vulcano' (Chamaerops humilis 'Vulcano') 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 from wet feet
Heavy, waterlogged soil or constant winter wet rots the roots. Plant in gritty, fast-draining mix and water sparingly in cold weather.
Magnesium deficiency yellowing
Older fronds yellowing from the margins inward usually signals magnesium shortage. Apply a palm feed with added Mg, or Epsom salts, in the growing season.
Scale and spider mites
Indoors or under glass it can pick up scale insects and red spider mite in dry air. Inspect frond undersides and treat early with horticultural oil.
Loose, leggy growth in shade
Too little light makes the clump open and floppy, losing the prized dense silvery form. Move it into full sun to restore compactness.
