No, it is best to avoid fertilizing Plumeria during the dormant season. The plant is not actively growing during this time, and fertilizing can stimulate new growth, which may be susceptible to frost damage in colder climates. Resume fertilization in spring when the plant begins to actively grow again.

Rooted Plumeria cuttings can be fertilized with a balanced, diluted liquid fertilizer every 2-4 weeks during the growing season. Reduce or stop fertilization during the dormant season to avoid promoting excessive growth.
