Overwintering Tropical Hibiscus Indoors in New York

Keeping Hibiscus rosa-sinensis Alive Through a Northern Winter

Tropical hibiscus can survive indoors with minimal care.

Indoor Care (October–April)

• Place in a south- or west-facing window.
• Expect leaf drop and reduced blooming (semi-dormancy).
• Water sparingly—just enough to prevent desiccation.
• Do not fertilize.

Spring Transition

• After last frost, when nights are consistently >50°F (10°C), move outdoors.
• Harden off 10 days in shade before full sun.
• Resume watering and fertilizing.

The plant will rebloom vigorously in summer.
