Cretan Date Palm problems — and how to fix them
Cretan Date Palm (Phoenix theophrasti) 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.
Fusarium wilt (Fusarium oxysporum f. sp. canariensis)
A lethal vascular disease spread via contaminated pruning tools. Fronds yellow and collapse from one side downward. No cure once systemic; sterilise cutting tools with bleach between palms and remove infected material promptly.
Red palm weevil (Rhynchophorus ferrugineus)
A devastating invasive pest in Mediterranean regions. Larvae bore into the crown, causing fronds to collapse inward. Early symptoms include fermented odour and soft crown tissue. Preventive systemic insecticide drenches are the primary control.
Magnesium deficiency
Shows as yellow banding along older frond leaflets while tips stay green. Apply magnesium sulphate (Epsom salt) drench at 30 g per litre, or use a palm fertiliser with chelated magnesium. Common in leached sandy soils.
