Palm and tree questions
When should palm trees be trimmed in Florida?
Most palms need pruning once a year, and coconut palms every 6 months. Timing depends on the species: cabbage palms August to October or December to May, thorny date palms April to May once pods form, and queen palms twice a year.

Timing by species
Cabbage (sabal) palms: August to October, or December to May to fit the budget year.
Thorny date palms (Sylvester, Canary Island, Medjool): April to May, once the seed pods form.
Coconut palms: every 6 months. Queen palms: twice a year recommended.
Dead fronds come off before June 1. That cuts storm debris going into hurricane season.
What to cut and what to leave
Dead fronds, spent flower stalks, seed pods and every frond below the 9-and-3 line come off. Nothing above the line is cut. A frond above the line is a store of potassium and magnesium; cut it, and the palm pulls those nutrients from the fronds that are left.
Every cut on a palm is permanent. A palm cannot seal off a wound the way a tree does, so each one stays an open door for trunk rot and palmetto weevil.
No hurricane cuts
A "hurricane cut" strips the palm to a narrow tuft. It looks tidy for a month and weakens the palm going into storm season. Living fronds are the palm’s reserve. Taking off dead fronds before June 1 cuts storm debris; cutting above the 9-and-3 line does not.
Clean tools on date palms
Fusarium wilt moves from palm to palm on pruning tools. On Canary Island date, Medjool and Sylvester palms, we recommend sterilized handsaws, cleaned between every palm.
