Silver Date Palm problems — and how to fix them
Silver Date Palm (Phoenix sylvestris) 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 palm weevil (Rhynchophorus ferrugineus)
Larvae bore into the crown and trunk, causing fronds to collapse inward; early signs are a fermented smell from the trunk and oozing sap — contact local plant health authorities as this is a notifiable pest in many regions.
Fusarium wilt
The fungal pathogen Fusarium oxysporum f. sp. canariensis causes one-sided frond die-back starting with older leaves; there is no cure — infected trees should be removed and destroyed to prevent spread.
Magnesium deficiency
Older fronds develop a broad yellow band along their margins while the mid-rib stays green; correct by applying magnesium sulphate (Epsom salt) as a soil drench in spring and summer.
