Plant Care

Propagate from the seed in spring at 64-73°F (18-23°C). Root softwood cuttings in late spring using bottom heat. Softwood cuttings are cuttings taken from young, non-woody growth. Root semi-ripe cuttings in summer. Semi-ripe cuttings are cuttings taken from semi-mature wood.

Plant Growth:

Grows best in full sun with some midday shade. Train Mandevilla over a pergola, trellis, or arch. Mandevilla is also useful as a screen. Where not growing hardy, raise plants in a warm or temperate greenhouse. A warm greenhouse has a minimum temperature of 55°F (13°C). During the day, temperatures should be set to 55-64°F (13-18°C) or above, and at night, the temperature should be at 55°F (13°C). Temperate greenhouses have daytime temperatures set between 50-55°F (10-13°C), and a nighttime temperature of 45°F (7°C).


Blooms flowers with 5 broad petal lobes.

Soil and Irrigation:

Does best in medium fertile soil that is moist, yet well-drained. Soil-based potting mixes work fine for indoor plants. Water moderately during the growing season, less in winter.


Needs moderately fertile soil to grow well. Apply a balanced liquid fertilizer on a monthly basis during the growing season.


Conduct pruning in late winter or early spring. Spur prune, by cutting back side shoots to 3-4 buds from the permanent framework. Thin out overcrowding shoots.


Vulnerable to spider mites, mealybugs, root rot, whiteflies, gray mold, and leaf spots.
