Mandevilla winter care

Mandevillas are one of the most adorable plants for their beauty and lush colors which you can easily grow in your garden. A few years ago, this plant was rare because only a few varieties were available in the market. Thanks to the crossing, Mandevilla plants with a wide range of colors are now available in different sizes. You can grow this plant to outdoor landscapes, patio or other indoor places. As Mandvellia is sensitive to snow, they need to be kept indoors or covered during winter months. 

Mandevilla Categories

You can get lovely Mandevilla flowers in an array of colors, as well as plants that grow different sizes, including vines. Mandevilla plants are of two categories – Mounding Mandevillas and Mandevilla vines.

Mandevilla vines are primitive, and most gardeners are familiar with this type. If you plant them under the trellises or other structures, they twine and climb up on the structure. As they grow up, you have to support and wind Mandevilla vines in clockwise or counterclockwise direction. The height of these vines depends on the variety. A typical Mandevilla grows between 10 to 15 feet in height. Although they grow vertically, you can control your Mandevilla vines to grow horizontally. 

Mounding Mandevillas form mounds as they grow in length rather than coiling up. These are ideal for raised beds, borders, container gardening, and landscape beds. They grow around 14 to 18 inches wide and tall. While these are easy to maintain and control, they are widely used in window boxes and hanging baskets. 

Mandevilla Varieties

Carmine King Mandevilla

This is an evergreen variety that blooms fringed deep red flowers with a size of 3 to 5-inch length. The red color spreads through parts including floral tube and throat. This is a vigorous growing variety with moderate branches. It needs wrapping around arbors or trellises. 

Crimson Mandevilla

This variety grows higher than other Mandevillas. Its vibrant and gorgeous red color gives it a place in bouquets to back red roses. The leaves of the vine are glossy, big and lush in texture. It suits perfectly in landscapes and patios. It grows best during summer and in frost-free regions. 

Giant Pink Mandevilla

This Mandeville variety produces pale pink blooms that start to appear in early summer. It comes with large and glossy green foliage. It can survive through the frost and hence suitable for cooler regions. 

White Mandevilla

This is a frost and humidity resistant variety. It produces showy white blooms from early summer. The vine grows fast and gives out oval shaped pointed leaves that are 4 inches long. 

Summerville Mandevilla

This is a mounding variety that produces rich and vibrant red flowers. It is a perennial kind and so produces flowers round the year in moderate climate

Variegated Mandevilla

It is a soft-stemmed vine that grows well in containers. This variety was recently discovered in Florida. It is speculated to be created due to natural mutation. It has a hard stem and grows well in winter. 


Mandevilla plants are generally brought as potted plants from the local store. They need to be planted during early June when warm weather is established. Mandevillas can be grown in containers, hanging baskets or directly in the ground.

Since these plants generally are not winter-tolerant, its best to grow them in containers. First off, pick a spot that has arbor, trellis, fence or mailbox next to it. Next, dig a hole as much as it can hold the root ball and is twice its size. Place the plant, fill the hole with soil and gently press around the stem. Water the soil thoroughly and do not water for the next 4 days. For planting in containers, use containers of size 12 to 14 inches. Limit one plant per container and use a well-drained potting mix. 


Mandevilla prefers regular watering whether it is planted indoors or outdoors. For indoor plants, thorough weekly watering along with good draining is necessary to keep the soil moist. During winter months, watering should be reduced to such that the soil gets dry between waterings. For helping the container to drain water, perlite or sand should be added to the soil along with a hole at the container bottom. 


Fertilizing Mandevillas is not required if they are planted in moderately fertile soil. Feeding a timed-release all-purpose fertilizer (10-20-10 at fertilizer grade) helps when they are potted. Moderate using of fertilizer keeps the soil nutritious over time and boosts the frequency of flowering. 


You can prune Mandevilla at any time of the year when they seem too large. If Mandevillas are grown in partial shade or full shade, regular pruning helps them look more beautiful. Regular pruning also helps prevent attack by pests such as mealybugs, whiteflies, and spider mites. If you find any dry or diseased leaves, feel free to dispose of them. 


Most Mandevilla varieties are drought and heat tolerant and so require less care once they are established. In colder climates, you should put the plants in full sun for 6 to 8 hours, and they will be fine every day. They perform well in sun and partial shade. In summer, Mandevillas do best in afternoon shade. 

Winter care

Certain Mandevilla varieties cannot survive if the temperature drops below 45-degree Celsius. If your place goes through such a climate, you might need to replant Mandevillas every year. Planting Mandevillas in a container and moving them in and out of the house based on the climate change can help preserve the plant. During frost, keep the plant on a spot which is warm. A shop light or plant light could be convenient for you in this case.

During winter, water your Mandevilla only when the top one or two inches of the soil feels dry. Due to chilly weather and less light, the plant grows slowly and absorbs less water.

Practically, Mandevilla needs no special arrangements (except a little bit warm) in winter unless its frosty.


Both Vining and Mounding Mandevillas will do fine if you follow the above suggestions. These tropicals are easy to care for and flower almost nonstop to keep your place always fresh.
