Mandevillas are tropical plants that can be grown as perennials in USDA zones 9-11. In colder climates, they can be overwintered indoors.
Plant mandevillas in a sunny spot with well-draining soil. Provide support for climbing varieties and regular watering to keep the soil moist.
Choosing the Right Location
Fertilizing and Pruning
Feed mandevillas with a balanced fertilizer every 2-4 weeks during the growing season. Prune them to control size and promote bushier growth.
