The red mandevilla plant is a flowering vine. It blooms large trumpet-shaped red flowers. Other varieties of mandevilla will blossom white or, more commonly, pink. The red mandevilla originates from the tropics of South America. Because of this, it is typically grown as a houseplant indoors.
Red Mandevilla's Preferred Climate
The red mandevilla plant cannot tolerate cold weather. Therefore, it can only be grown outdoors in climates that stay warm year-round, like the tropical portions of the southern U.S. If the temperatures in your area dip below 40 degrees Fahrenheit in the cooler season, then the red mandevilla is best kept as a houseplant. It should only be brought outdoors in the summer months.
Red Mandevilla Care
The red mandevilla does not do well in direct sunlight. The plant should be placed in partial shade when outdoors. This makes it an ideal porch plant. When kept indoors, red mandevilla shouldn't be placed in windows, where they will receive lots of light directly throughout the day. Instead, place the plant near a window, but far enough away that the light received is of the indirect variety. Alternatively, a red mandevilla can be placed underneath a filtered light source. Use a rich loamy soil with a container that drains well. Red mandevilla vines grow rapidly and should be pruned in the winter, after leaves have been shed.
Pests of the Red Mandevilla
Red mandevilla is susceptible to infestation by spider mites, whitefly, scales and mealybugs. Leaves will appear chewed, have a yellowed appearance or become spotted. Pick off insects and infested leaves when you see them. If the insect population is large, treat with insecticide. If you have a scale problem, you will likely observe waxy deposits on stems. Pick these off as quickly as possible. If the mandevilla is afflicted by spider mites, you will see small red moving spots on the leaves and there will be webbing on the plant. Wipe the plant down with alcohol if this is the case.
Preventing Disease in the Red Mandevilla
Fungal disease can occur when the mandevilla plant is overwatered and has poor soil drainage. Following care recommendations and applying fungicide can prevent this issue from occurring. When bringing your red mandevilla plant indoors for the winter, inspect for insects or signs of infection. Washing the plant gently with a soapy cloth, rinsing and patting dry will remove fungal spores and any insects that may be on the plant and will prevent disease. Prune in the winter while the mandevilla plant is dormant, as this will enable better healing and reduce chances for infection by pathogens.
