Palm trees are relatively low-maintenance when it comes to pruning, but it's still important to know when and how to trim a palm tree. Unlike many other plants, cutting back the green fronds won't help with growth. In fact, pruning healthy fronds will just minimize food production and ultimately weaken the tree.
However, occasionally you'll have to remove a healthy frond if it's too close to a structure or blocking a road or sidewalk. Otherwise, most of your pruning will be to remove brown fronds, as well as flowers and fruits. The best time to prune is in the spring, especially prior to hurricane and fire season.
To remove dead, dying, or damaged fronds
To eliminate flowers and fruits that can sap the tree's energy and be a hazard to those below if they drop
To improve visibility, such as near a roadway
To reduce fire hazards and other damage from fronds too close to structures
To get rid of unwanted seedlings
To shape for cosmetic purposes

Examine Your Palm Tree
Begin by taking a good look all around your tree. Note whether any fronds are completely brown. You can leave fronds that are turning from green to yellow, as they're still providing the tree with some nourishment.
Also, note whether any fronds have been broken and are at risk of falling. Likewise, look for fronds that are too close to structures. Finally, check for fruits and flowers, and put them on the to-prune list.
Plan the Prune
Determine the tools you'll need. In most cases for DIY palm tree pruning, this will include a pruning saw and hand pruners. Prior to making your cuts, sanitize your pruning tools by wiping down the blades with rubbing alcohol on a clean cloth or paper towel.
As the rubbing alcohol dries, determine the order in which you'll make your cuts, so nothing is ever at risk of falling on you. It's often best to work from the lower fronds upward, so you have a clearer path as you reach up for fronds. Bring out a step stool if necessary.
Make the Cuts
Cut fronds at least 2 inches from the trunk. This will prevent damage to the trunk that can introduce pests and diseases.
As you remove fronds, fruits and flowers will be easier to see. So be on the lookout for any that you hadn't previously noted in your tree inspection.
Responsibly dispose of your pruning waste. Fruits, flowers, and other debris left at the base of the tree might attract pests or even result in unwanted trees growing.
If you're unsure of how to dispose of your palm fronds—especially diseased fronds—call your local public works department for information. Many areas have special instructions regarding palm waste.
