If you see roots circling around the bottom of your Plumeria’s pot, it may be root-bound, which can harm the plant’s health. You can prevent this by repotting it into a larger pot with fresh, well-draining soil. While repotting, gently loosen the root ball to encourage new root growth. Make sure the pot has drainage holes and avoid over-potting. Regularly check and repot your Plumeria as needed to maintain healthy root development and prevent the negative effects of root-bound conditions.
