If you reside in a cooler climate, you may think that growing mandevilla is impossible. Native to the warm, humid regions of the Americas, these plants do not thrive in sudden temperature changes. However, with the right approach, anyone can successfully cultivate mandevilla in pots.
There are two main types of mandevilla to consider: the mounding variety, which has a bushy form, and the vining type that cascades beautifully over trellises or other structures. In smaller spaces like narrow gardens or balconies, opting for upward growth can help maximize your area while adding visual interest.
If you're looking to add some excitement to your garden this year, learning how to grow mandevilla in pots is essential. I consulted with a tropical plant expert from Florida to uncover the best techniques for nurturing these sun-loving beauties.
How to Successfully Grow Mandevilla in Pots
If you're gardening in limited space, mandevilla is a fantastic choice to brighten up your environment.
While these plants have specific requirements for heat and humidity, when placed in the right location, these perennials will deliver continuous color throughout the summer months.
Essential Tips for Growing Mandevilla in Containers
"Mandevilla thrives beautifully in pots, making it an ideal choice for cooler climates like US hardiness zone 7 and below, where they can be brought indoors during winter," explains Tatiana Anderson, a plant expert and co-founder of Top Tropicals.
You can order mandevilla live plants from Amazon.
"Start by selecting a pot with a diameter of at least 12 to 16 inches and ensure it has multiple drainage holes," Tatiana advises. "Find a sunny, sheltered spot in your garden where the plant can receive at least six to eight hours of direct sunlight each day to promote blooming.
These tropical garden plants dislike sitting in waterlogged soil, so it's crucial to use a well-draining potting mix. Adding perlite can improve aeration, and a combination of garden compost, sand, and grit can enhance drainage," she adds.
For climbing varieties, you'll need to provide a support structure. Consider using a sturdy metal obelisk, available on Amazon, which will look stunning both in winter and during the growing season as it becomes adorned with foliage and flowers.

Care Tips for Potted Mandevilla
"Water mandevillas only when the top inch of soil feels dry, avoiding overly damp conditions," Tatiana advises. "You don't want the soil to dry out completely, but deep watering once or twice a week during the summer will be beneficial."
Grouping pots together can help boost humidity, which many mandevilla species prefer, given their rainforest origins. Arranging pots in clusters of odd numbers, like three or five, creates a visually appealing layout.
"These plants are quite hungry and should be fertilized every two to four weeks during the growing season, using a balanced, water-soluble fertilizer rich in phosphorus (like 10-30-10) to encourage more blooms," Tatiana recommends.

Regular deadheading and light pruning after flowering will help encourage new growth and ongoing blooms," Tatiana adds.
As the growing season ends, gardeners in cooler climates should bring their potted mandevilla indoors to a bright, cool area, ideally maintaining a temperature of 50 to 60°F (10 to 15°C).
When overwintering mandevilla, reduce watering to once a month or as needed, and halt fertilization completely. You can move your pot back outside in the spring once the frost threat has passed.
"Repot mandevilla plants every three years," Tatiana suggests. "This should be done in early spring before they start actively growing, refreshing the soil and upgrading to a slightly larger pot if needed."
Best Mandevilla Varieties for Pots
With around 160 species native to the equatorial regions of the Americas, you can find mandevilla in various colors, including red, pink, yellow, and white.
"In Florida, the pink 'Alice du Pont' variety does particularly well in pots, thriving in the heat and humidity while offering blooms throughout the season," Tatiana shares.
Live 'Alice du Pont' mandevilla plants are available for order on Amazon.
Another great compact option is the 'Sun Parasol' series, featuring deep red, pink, or white flowers, perfect for container growth in limited spaces.
Consider trying this yellow 'Sun Parasol' mandevilla, available on Amazon, which produces stunning two to three-inch golden blooms to brighten your outdoor displays.
Common Questions
Is Mandevilla Toxic to Pets?
Yes, mandevillas are considered toxic to both people and pets. Their sap can irritate the skin, so be sure to wear gloves while handling them. Watch your pets and children when they are outside, especially when the flowers drop.
"Mandevilla is relatively resistant to pests but may attract aphids, spider mites, and whiteflies," Tatiana notes. "Keep an eye on your plants during the summer. If you notice white insects on the leaves, you can either spray them off with a hose or use an organic neem oil solution. Alternatively, learn how to attract ladybugs to your yard to encourage beneficial insects for natural pest control."
