The tropical vine mandevilla is a natural occurring plant. It has trumpet-shaped blooms that can grow up to 4 inches (10 cm) wide and are bright and typically pink. The plants have a temperature minimum of 45-50 F (7-10 C) and are not winter hardy in most parts of the United States. You’ll need to grow mandevilla as a houseplant unless you’re in the tropical south. Growing mandevilla vine indoors takes up some space, so this plant has specific needs.
Mandevilla Growing Conditions
In colder climes, you’ll need to keep mandevilla as a houseplant during the fall and winter since the vine is hardy to USDA zone 9. Vines may grow up to 30 feet (9 m.) in length and twine around any available structure or support in nature.
In rich moist soil with plenty of organic matter, they prefer partial sun. In the spring and summer, when they are outdoor plants, they require frequent watering and feeding with a high phosphorus food.
In the winter, the plant will go dormant, and some of its leaves may even perish. But when spring arrives, the air will warm up, and the plant will re-establish itself. Mandevilla thrives in temperatures above 60 degrees (15 degrees Celsius) at night.
Mandevilla as a Houseplant
Different growing conditions are available to the plant once it is moved to the interior. As a result, it’s vital to learn how to grow mandevilla indoors. Before you are certain there are no bug hitchhikers, move mandevilla houseplants indoors.
Mandevilla houseplants are difficult to grow and need particular conditions. This isn’t a little counter top or window box houseplant, as it can grow 7 to 10 feet (2-3 m) per season in its habitat. To keep the plant within the confines of the room in which it is growing, trim it as necessary.
You may grow the plant in a sunny window with some protection from searing midday heat, or in a greenhouse environment. Don’t be surprised if your mandevilla vine does not bloom indoors. To force buds and flowers, you’ll need a lot of extra high artificial light.
While overwintering mandevilla indoors, the plant will not bloom, and it will go dormant until brighter spring light arrives.
How to Care for Mandevilla Indoors
You can either grow it like a regular plant or cut it back to 8 to 10 inches (20-25 cm.) and pot it up. Move the pot to a temperature range of 55 to 60 F (13 to 15 C) in a cool, low-light area.
In the dormant phase, cut back by half and clean out dead leaves and plant debris in the spring. To avoid rot, the indoor mandevilla plant should stay fairly dry.
During the winter, keep the indoor mandevilla plant reasonably dry, and in the spring, you should see sprouts. Force bushier growth by moving the pot to a sunny spot and pinching the shoots. Every two weeks, apply a high phosphorus plant food to your garden.
Winterizing Mandevillas: Tips For Overwintering A Mandevilla Vine
The vine mandevilla has vivid crimson, pink, yellow, purple, cream, and white blooms that are magnificent and glossy. In a single season, this graceful vine may reach 10 feet (3 meters) in length.
If you reside in a tropical environment that falls within the USDA plant hardiness zones 9 and above, mandevilla plants in winter endure the season in good health. Planting the vine in a container is the best option if you live in a northern climate. This tropical plant must be wintered indoors because it cannot tolerate temperatures below 45 degrees F (7 degrees C).
How to Overwinter Mandevilla as a Houseplant
Grow a houseplant until temperatures rise in the spring if you bring a potted mandevilla plant indoors before the mercury drops below 60 degrees F. (15 C). Trim the shrub down to a manageable size and Plant it in a location with plenty of bright light. Temperature is comfortable in the room; there is no sound for 0 seconds and 23 seconds.
Daily watering and trimming are required to keep the plant at a desired size and form. The plant isn’t going to bloom during the winter, so don’t expect flowers.
You can bring the mandevilla indoors and store it in a dormant state if you’re short on bright light or space. Cut the plant back to about 10 inches (25 cm.) and put it in the sink to wash away pests that may be hiding in the potting mix. You may see yellowing and subsequent leaf drop if you don’t want to trim it back; this is common.
Plant the plant in a room that is between 55 and 60 degrees F (12 and 15 degrees C) and places it in full sun. Throughout the winter, there is hardly any water, and the potting mix stays just moist enough. Move the mandevilla to a warm, sunny room and resume normal watering and fertilization when you see early spring growth indicating the plant is breaking dormancy.

Should I Cut Back Mandevilla – When To Prune Mandevilla Vines
In hot weather, mandevilla is a stunning and prolific blooming vine. It will grow quickly and reach a length of 20 feet (6 m.) if it isn’t exposed to cold temperatures. It may develop an unkempt look if it is not cared for, and it will not flower as much as it might. Pruning mandevilla vines at least once per year is therefore advised. To find out how to properly cut a mandevilla vine, keep reading.
Should I Cut Back Mandevilla?
With a resounding yes, this is a frequently asked question. The success of mandevilla vines depends on when to trim them. Late winter or early spring is the best time to trim a mandevilla vine, before it starts to produce new growth.
The summer flowers bloom on the new growth of mandevilla vines, which puts out new growth regularly and fast. As a result, unless you cut the mandevilla vine down to nothing in the spring before it puts out new shoots, it will not be harmed or significantly affected by your trimming.
Old growth or trees that are out of control may be chopped down to the ground. In the spring, they should have new robust stems. Pruning branches that aren’t becoming unmanageable also benefits the rest of the plant, promoting new growth and giving it a bushier, more compact appearance. Many shoots of new growth should sprout from a single stem of old growth that has been cut back.
Throughout the growing season, you may also trim back a mandevilla vine. Pruning new growth lightly, rather than forcefully, is recommended because it results in fewer flowers. Nonetheless, when new growth is approximately 7.5 cm (3 in.) long, you may pinch off the ends of it in early spring. This should lead to the plant becoming fuller and more likely to bloom by dividing into two new shoots.
Repotting Mandevilla Plants: Learn How To Repot Mandevilla Flowers
With huge, leathery leaves and beautiful, trumpet-shaped blooms, mandevilla is a dependable blooming vine. The vine, on the other hand, is frost tolerant and can only be cultivated outdoors in USDA plant hardiness zones 9 through 11 due to its sensitivity. It’s cultivated as an indoor plant in colder climes.
Repotting is required on a regular basis to maintain the plant and give the roots enough growing area, as with all potted plants. Fortunately, repotting mandevilla is not difficult. Read on to find out how to repot mandevilla in a new pot.
When to Repot a Mandevilla
Every year or two, mandevilla should be repotted, preferably in the early spring. Nonetheless, it’s recommended to wait until fall to prune and replant your mandevilla vine if you didn’t get around to doing so last year. 0% of 1 minute, 23 seconds Volume
How to Repot Mandevilla
Prepare a pot no bigger than one size larger than the current pot for repotting a mandevilla. The container should be just enough larger, yet not too deep. Mandevilla is prone to root rot in soggy, poorly drained conditions, so make sure the pot has a drainage hole in the bottom.
Add a lightweight, fast-draining potting soil, sand, and compost to the pot until it is about one-third full. Carefully remove the pot from the plant. Trim any dead or damaged roots that seem to be there.
Place the plant in the middle of the pot. If necessary, adjust the soil in the mandevilla’s current pot to ensure it is planted at the same depth as it was when it was originally bought. When shifting to a new pot, excessively planting might harm the roots.
Mix in some potting soil around the roots. With your fingers, firm up the mixture but don’t compact it. Install a trellis to support the vine once you’ve watered the mandevilla plant well. Move the mandevilla into bright sunlight after it has been in light shade for a few days to acclimatize to its new pot.
