Growing Mandevilla: Outdoor And Indoor Options
Mandevilla can be grown outdoors year-round in frost-free regions with a temperate climate. In colder climates, it is treated as an annual or overwintered indoors. When planting mandevilla outdoors, it is best to do so in mid to late spring after the last frost.
To ensure optimal growth, plant mandevilla in a sunny site with rich, well-draining soil. This plant thrives in warm temperatures and high humidity, making it suitable for tropical and subtropical regions. However, be cautious as temperatures below 45-50 degrees F can cause cold damage. In drier climates, regular misting can help increase humidity levels and promote overall plant health.
For those growing mandevilla as a houseplant, place it in a well-lit area with indirect sunlight such as a bright window. When temperatures drop to 50 degrees F, bring the plant indoors for winter. Avoid overwatering and cease fertilization during this period. Additionally, check for pests regularly to ensure the plant’s well-being during indoor overwintering.
Care And Maintenance Tips For Mandevilla
Pruning is essential for the care of mandevilla plants and should be done in late winter or early spring, before new growth begins. Mandevilla vines have a twining habit and can grow up to a third of their size, so pruning is necessary to remove dead or diseased branches and shape the plant as desired. Note: Mandevilla blooms on new growth, so pruning later in the season may result in a loss of flower buds.
For optimal growth, mandevilla thrives in sandy, well-draining soil that has been amended with compost or other rich organic matter. Good drainage is critical to prevent root rot, which can harm the plant. If you’re growing mandevilla in containers, it’s recommended to use a high-quality, all-purpose potting soil with adequate drainage holes.
Regular fertilization is necessary to promote abundant blooms in mandevilla. Feed the plant every two weeks with a slow-release fertilizer or a liquid fertilizer high in phosphorus, specifically formulated to encourage flowering. However, stop fertilizing from fall to early spring if you’re overwintering mandevilla indoors.
Maintaining proper moisture levels is crucial for the health of mandevilla. The soil should be kept moist but not waterlogged, as overwatering can lead to root rot or fungal diseases. Underwatering can cause stress and result in fewer flowers. Therefore, it’s important to strike a balance and regularly check the soil moisture to ensure optimal growing conditions for mandevilla.
Since mandevilla is a climbing vine, it requires a support system such as a trellis, pergola, obelisk, or arbor for proper growth. Providing a sturdy structure will help the vine climb and thrive as it reaches its full potential.
Pests And Diseases: How To Keep Your Mandevilla Healthy
When grown under optimal outdoor conditions, mandevilla is usually free from pests and diseases. However, when overwintered indoors, it becomes more susceptible to common pests such as aphids, scale, mealybugs, spider mites, and whiteflies. In such cases, it is advisable to apply insecticidal soap or neem oil according to the instructions to eliminate these pesky invaders.
Mandevilla can also be prone to various diseases, including root rot, powdery mildew, anthracnose, leaf spot, botrytis, fusarium rot, Southern wilt, and crown gall. Proper care and maintenance, such as maintaining good airflow around the plant, providing adequate sunlight, watering correctly, and avoiding over-fertilization, can help prevent these diseases.
Regularly inspecting the plant for any signs of pests or diseases and taking appropriate action at the first sight of an issue is crucial for keeping mandevilla healthy and thriving.

Frequently Asked Questions
Do mandevilla grow back every year?
Mandevilla plants are indeed capable of growing back each year, given the right conditions. While they are considered perennials in warmer zones 9 to 11, mandevillas cannot survive freezing temperatures. As a result, in most regions of the United States, where winter brings frost, they are grown as annuals. However, for those living in colder areas, it is possible to keep mandevillas alive by bringing them indoors during the winter months. By providing a suitable environment and protecting them from freezing temperatures, mandevillas can be safeguarded and encouraged to regrow in the following year.
How do you keep mandevilla over winter?
To keep mandevilla over winter, it is essential to provide the right conditions for its dormant period. Once the temperature drops and it is no longer safe to keep the vine outside, you can transfer it to a cool garage or basement with a consistent temperature above freezing. Maintaining a chilly environment around 50? F is ideal for the plant’s winter dormancy. Moreover, to ensure the best chances of survival, it is recommended to prune the mandevilla back extensively, cutting it back to approximately 12 inches in height.
Do mandevillas lose their leaves in winter?
Yes, mandevillas do lose their leaves in winter. As the foliage drops off, it is recommended to trim the vines down to around 8-12 inches. However, come springtime and warmer weather, they will begin to regrow. Keeping the greenhouse temperature at 65 degrees Fahrenheit or above ensures continuous growth during winter, and with adequate light, they will even bloom.
How long does a mandevilla live?
Mandevilla plants have a remarkable lifespan, flourishing for several years in their native tropical or subtropical environments. Their blooming period begins in late spring and continues uninterrupted until October. These resilient plants showcase their vibrant blooms year after year, contributing to the lush beauty of their surroundings.
