Christmas Palm problems — and how to fix them
Christmas Palm (Veitchia merrillii) 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.
Lethal Yellowing disease
The most serious threat to this species; caused by a phytoplasma transmitted by planthopper insects. Symptoms progress from premature fruit drop to yellowing and browning of fronds from the bottom up, leading to rapid palm death. No cure exists; preventative trunk injections of oxytetracycline are used in high-risk areas.
Cold damage
Extremely frost-tender; sustained temperatures below 5°C cause irreversible frond damage, and any frost is typically fatal. In the UK, must be grown in a heated greenhouse or conservatory maintaining a minimum of 13–15°C through winter.
Magnesium deficiency
Common in sandy or leached soils; causes yellowing bands along the margins of older fronds (distinct from the full-leaf yellowing of Lethal Yellowing). Apply magnesium sulphate (Epsom salts) drenches or a palm fertiliser containing magnesium.
