Plant Profile: Mandevilla sanderi

A tropical vine often cultivated as a houseplant in temperate climates, this plant is sensitive to cold. When grown outdoors, it’s best to keep it in a container and bring it inside during frost, allowing the soil to dry out in winter. Before returning it outdoors in the spring, prune the plant. It thrives in moist, well-drained soil and benefits from afternoon shade in hot, humid environments. This vine is also tolerant of coastal conditions, requiring ample water during the summer months.

When kept indoors, it prefers bright, indirect light, a typical room temperature, and high humidity levels. The soil should be kept moist but not overly wet. To encourage a fuller growth habit, pinch back any leggy stems, and consider using a trellis or stake for support.

In terms of pests and diseases, this plant generally faces few issues, though it can attract mealybugs, aphids, and scale insects.
