Container culture of Mandevilla sanderi

When grown in containers, the plant requires a substrate with high aeration and drainage due to the sensitivity of its root tubers to waterlogging. The choice of container size depends on the plant variety: 4–10 liters for compact forms and 8–25 liters for vigorous ones; dark-colored pots should be avoided to prevent root overheating.

Mandevilla sanderi is a vine and requires the installation of supports for vertical growth, and mandatory pruning in late winter or early spring is necessary to stimulate the formation of flower buds on the current year's shoots. The plant requires bright, indirect light and should be moved outdoors in summer; however, when nighttime temperatures drop below 10–12°C, it must be brought indoors for overwintering.

During the active growing season, fertilizing is carried out every two weeks, and it is important to limit nitrogen application to promote flowering rather than vegetative mass. A distinctive feature of this crop is the need for strict adherence to a regimen that combines outdoor summer maintenance with a period of winter dormancy.
