Troubleshooting
Cliff Date Palm problems — and how to fix them
Cliff Date Palm (Phoenix rupicola) 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.
Leaf tip browning
The most common cosmetic complaint; usually caused by low humidity, fluoride in tap water, or under-watering.
Magnesium deficiency
Yellow bands on older fronds are the classic symptom; apply magnesium sulphate at label rates.
Root rot
Caused by poorly drained soil or overwatering; plant in well-draining substrate and avoid irrigation excess.
Scale insects
Inspect the base of fronds regularly; treat with horticultural oil spray.
Slow growth in low light
Noticeably slower indoors; supplement with a grow light if natural light is limited.
