Troubleshooting
True Date Palm problems — and how to fix them
True Date Palm (Phoenix dactylifera) 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.
Sharp basal leaflet spines
The lowest leaflets are modified into rigid needle-like spines that can puncture skin and eyes; prune the spined section off accessible fronds and handle with care.
Poor fruiting in humid or cool climates
Dates need long, hot, dry summers to ripen; in mild-maritime or humid regions the palm grows but the fruit fails to mature or rots.
Potassium / magnesium deficiency
Older fronds show marginal yellowing and necrosis on sandy soils; correct with a palm-specific feed and avoid over-trimming.
Bayoud disease / Fusarium
A serious soil-borne wilt in some growing regions; plant resistant cultivars and avoid moving infected offshoots or soil between sites.
