Ponytail palms require consistently warm temperatures and low moisture. In the US, they can survive outdoors in Zones 9 and warmer, but only where it’s also quite dry, such as in the Southwest. We imagine it would get too humid and wet in Mississippi for a ponytail palm to thrive, so it would probably be best to keep yours potted. Consult a nearby Cooperative Extension service for local advice.
