Identifying and Overwintering Mandevilla in Rhode Island

The plant is Mandevilla, a tropical vine blooming spring to fall. In Rhode Island (Zone 6), it must come indoors for winter.

Care: Full sun, well-drained soil, let top 2 inches dry between waterings. Fertilize mildly every 2 weeks for best bloom. Pinch to shape; cut back for bushiness.

Overwintering: Bring inside before frost. Place in a south-facing window. Water sparingly, no fertilizer. It will survive and can return outdoors in spring. The expert has overwintered hibiscus, banana, and flowering maple this way.
