Along with a lack of water and sunlight, top-trimming is a common cause of palm tree deaths. Palm trees bloom from a central tip, and removing the growth causes the plant to die.
For a palm tree to grow properly, the plant must get enough sunshine and water throughout the day. Palm trees are hearty plants, but breaking limbs can cause significant damage to the way that they grow, so palm trees must be protected from limb damage caused by children or animals. Palms do not need constant direct sunlight, but they need it for a few hours a day.
