Experts recommend that you wait until spring to prune your palm tree. Those dead fronds may be somewhat unattractive, but they will help protect the palm from summer’s heat and winter’s cold. Sterilize and sharpen your pruning tools before you begin. Generally, you’ll need pruners, garden knives and pruning saws when you are trimming a palm tree. Wear safety glasses and protective gloves, as well as heavy pants and a shirt with long sleeves. Remove any hanging, dead or unhealthy fronds. All dry, wilted or diseased fronds should be removed. On the other hand, when you are pruning palm plants, don’t think you need to prune green, healthy fronds. There is no biological reason to do so and it can stress the tree. Be sure not to remove green fronds growing horizontally or pointing up.
