To keep Coconut palms in our region, they need to be moved into a greenhouse when the temperature falls below 50°F. So to keep them portable, they need to be kept in pots, which limits their growth too. This means that they wont grow large enough to produce coconuts. They can only be used for decoration here in southeast North Carolina.
Palms need sandy, well-draining soil to survive. If your planting spot has hard, clay-heavy soil, a larger hole needs to be dug and filled in with a layer of sand before planting the palm.
