Plumeria Leaf Loss in Winter: Can You Prevent It?

Why Plumerias Drop Leaves Indoors

A plumeria grown outdoors in summer and brought inside for winter drops all its leaves annually. This is normal—the plant goes dormant in response to lower light and cooler indoor temperatures.

How to Keep Leaves (If You Dare)

To prevent leaf drop, you'd need to maintain indoor temperatures of 75–85°F with bright sun—a sauna-like environment most gardeners won't tolerate. Instead, accept the dormancy: prune in spring to keep the plant compact, and consider decorating the bare branches with Christmas lights for a festive touch.
