Keeping this in view, will a palm tree grow back if you cut it in half?
If you’re planning to cut your Palm tree at the trunk level, it will NOT grow back. The only way that Palm tree growth can occur is at this base level called the growing tip, or sometimes even called the crownshaft, which is sitting at the base of the trunk and severing this part of the trunk entirely kills the plant.
Fill a bowl halfway with lukewarm or cool tap water, then submerge the exposed roots. Let the plant soak for around an hour so the roots are ready to be replanted.
