Palm Tree Fruit Removal
In addition to periodic pruning, you may want to remove the fruit stalks from certain palm trees to keep them safe and prevent future problems.
Queen palms fruit abundantly and can create a mess when the fruits fall on sidewalks or driveways. If left alone, the seeds may germinate and create a weed problem. Coconut palms produce heavy fruits that can pose a hazard to people or vehicles below.
In these situations, you can remove the fruits or even the flowering stalks on an as-needed basis.
It won't harm the tree and will prevent future issues. Never remove any green leaves, since doing so can damage the tree. If you're not able to do the job yourself, remember that you can always hire a certified arborist.
