Mandevilla Plant Care

Mandevilla (Mandevilla sanderi) belongs to the Apocynaceae family within the Mandevilla genus. Mandevilla is native to the State of Rio de Janeiro in Brazil. Mandevilla is also known as Brazilian Jasmine.

Mandevilla displays a climbing vine growth habit, reaching up to 10 inches tall with a spread of approximately 3 inches. Mandevilla produces large, showy trumpet-shaped flowers in various colors.

Leaf size: approximately 6 inches.

Mandevilla sanderi requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Mandevilla thrives in full sun to partial shade light conditions. The optimal light range is 2000–4000 lux. Avoid placing Mandevilla in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Mandevilla sanderi grows best at temperatures between 60°F and 80°F. Mandevilla prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, fertile soil with added perlite for extra drainage. Good drainage is essential for Mandevilla to prevent waterlogging, which leads to root rot and fungal issues.

Repot annually in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Mandevilla can be propagated through stem cuttings, layering.

Mandevilla is susceptible to aphids, spider mites, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Mandevilla grows outdoors in USDA Zone 13a. Native to the State of Rio de Janeiro in Brazil, Mandevilla is adapted to warm climates. In cooler regions, grow Mandevilla as a houseplant or bring it indoors before the first frost.
