The directions for taking care of a ponytail palm aren't very long. Because dry soil is best for ponytail palms, it is best to let them get too big for their pots before repotting. When you do report them, use a pot that is only an inch or two (2.5 to 5 cm) wider than the last one. If you move them to a bigger pot, they might get too much water at once, which could hurt their growth and health. https://www.thejunglecollective.com.au/ponytail-palm-beaucarnea-recurvata-plant-care-tips/
