Does Red Mandevilla Come Back Every Year?

Does Red Mandevilla Come Back Every Year?

Red Mandevilla planted outdoors in zones 8 typically die back to the ground but sprout from surviving roots the following spring. Red Mandevilla can be grown as annuals in colder climates or kept in pots year-round round and carried within when the weather turns cold.

Even when grown as annuals, established plants will produce the next few years. Red Mandevilla is a winter hardy succulent and does well in Southern California, but can be grown in colder climates as a perennial.

Mandevilla is an extremely popular houseplant. Mandevilla is easily grown in pots year-round. Place the pot in a location that gets some sun but does not get any direct afternoon sun, as this will scorch the leaves.

Red Mandevilla is tolerant of indirect light and thrives with only morning sunlight.  Placing the pot near windows with curtains that block the hot afternoon California sun rays is a good start. If your Red Mandevilla turns dark green, it has not received enough light.

Moving closer to a window or moving closer to other plants that are receiving direct sunlight may help this problem.

Red Mandevilla has a sweet-smelling flower that attracts bees and other pollinators. Red Mandevilla flowers are also attractive to butterflies. Red Mandevilla produces clusters of small flowers each winter if grown as annuals from seed.

How Do You Take Care Of Red Mandevilla?

Red Mandevilla is easy to care for and does not requires a lot of maintenance. Red Mandevilla requires full sunlight to flower successfully. They can, however, withstand mild shade.

Give your Red Mandevilla plant a high phosphorus, water-soluble fertilizer once every two weeks to receive the greatest Red Mandevilla flowers throughout summer. This will ensure that your Red Mandevilla blooms beautifully.

Red Mandevilla requires sandy, well-draining soil with sufficient organic matter. A decent potting mix includes peat moss, sand, and leaf mold.

The plant prefers slightly acidic to neutral soil pH, although it may also survive slightly alkaline soil. An excellent 20-20-20 ratio meal is beneficial to a variety of plants, including Red Mandevilla.

As part of a sustainable and clean landscape, use an organic formula. Apply a high phosphorus diet every two to three weeks early in the flowering season for more flowers. The following are the factors to consider when caring for Red Mandevilla:


Red Mandevilla requires full sunlight to partial shade. If it does not receive enough sunlight, it will produce a weak and thin stem. Red Mandevilla will produce flower clusters if it receives six hours of direct sunlight every day.  

If the plant receives less than six hours of sunlight in a day, then you need to plant it near a window that receives direct sunlight.  Placing the pot near windows with curtains blocking the hot afternoon California sun rays is a good start.


Red Mandevilla needs plenty of water to produce a healthy plant and to promote blooms. When the soil is dry, add enough water so that the soil begins to drain out of the bottom of the pot.  If your plant does not receive enough moisture, it may produce thin, weak stems, leading to fewer or no flowers.

It should also be noted that you do not want your Red Mandevilla’s roots sitting in water for an extended period. This is a sure way for physiological diseases in potted plants. The potting medium should be allowed to air-dry out completely before watering again.


Red Mandevilla prefers well-draining soil with plenty of organic matter. A decent potting mix includes peat moss, sand, and leaf mold. The plant can tolerate slightly acidic to neutral pH soil and thrives with a 20-20-20 ratio. However, it may also survive slightly alkaline soil conditions if you add Epsom salt every few months.


Red Mandevilla requires room night temperatures of 60 to 65 °F and day temperatures above 70 °F. The frost hardiness rating is 40 to 65 F (4-18 °C). It is important to provide adequate afternoon sunlight so that the plant does not produce weak stems.  If the temperature in your home is greater than 70 °F(21.1 °C), Red Mandevilla can be kept indoors year-round.


Red Mandevilla thrives with house moisture levels between 40 to 60 percent. Humidity levels that are too high or low may result in leaf browning or dehydration. The humidifier may also lead to fungal diseases in the soil. Red Mandevilla is the most common houseplant for making water bills go down.

Soil pH:

The soil should be kept slightly acidic to neutral for best results. Ideal pH levels are 6.6 to 7.8 (slightly acidic to neutral). If the soil is too acidic, add dolomite lime as needed until the desired pH is achieved. If your plant does not receive enough moisture, it may produce thin, weak stems, leading to fewer or no flowers.


Red Mandevilla does not require excessive fertilizer to produce a healthy plant. Feed your plant once every two weeks using high phosphorus, water-soluble soluble fertilizer for the best Red Mandevilla flowers all summer.

The best time to fertilize is early spring or summer when they are blooming or just after they have been pruned back and are growing new.  Feed the plants with a high phosphorus diet once a month in spring and summer in half-strength diluted fertilizer solution.

In the fall, apply an all-purpose formula for non-flowering plants every two weeks until March or April of the next year.


Red Mandevilla is easily propagated by cuttings or seeds in the spring and summer.  If you want to propagate Red Mandevilla, simply take a six-inch section of the plant’s stem and place it into a glass of water until the new plant has rooted.  

The cutting should be removed from the water once roots have formed – this may take a few weeks. The cutting can then be planted into regular potting soil.


Red Mandevilla must be repotted once every 1-2 years in the spring. Over time, the roots will grow out of their pots and can make them unstable.  Find a larger pot with proper drainage holes with the same type of soil as your current potting soil.

If you want to use your plant as a houseplant, then place it in a pot that is five to seven inches in diameter and nine to twelve inches in height.  If you prefer to use this plant outdoors, put it into a twelve-inch pot about one foot high. The best time for repotting is in late winter or very early spring.


Red Mandevilla must be pruned once a year in the spring and summer. The plants can be pruned back to about two inches high in early spring for new growth or just after the plant has finished blooming.

When pruning, do not remove more than one-third of the old growth on a plant at a time. Red Mandevilla will heavily re-sprout and produce new flower clusters if it receives enough sun throughout the day.

Pests and Diseases:

Red Mandevilla is prone to scale insects and mealy bugs that can infest the roots. Mealybugs can be controlled with neem oil, pyrethrin, and Malathion as control agents. Corn borers may damage the stem of your Red Mandevilla plant.

 As a result, pitting on the stem exposes the white sapwood in the center of the branch. This is caused by a fungus known as “crown gall.” Fortunately, this disease is easily curable with destructive root sprays such as soapsuds, wood alcohol, and methanol.

Is Red Mandevilla Perennial Or Annual?

Red Mandevilla is an annual flowering vine that only lives for one season. The plant will grow from seed or cut and will sprout in the springtime. It will flower throughout the summer before dying back in the fall. It can be placed outdoors or indoors as a houseplant.

Spring is the ideal time to repot your Red Mandevilla into larger pots because it will not have time to get root bound before blooming takes place. Red Mandevilla thrives in full sunlight and will die back if not given sufficient sunlight.

Red Mandevilla can be grown indoors as a houseplant or outdoors as an annual. The plant needs to be pruned so that the blooms do not become so large that the plant is unable to flop over in the wind. Also, it should be pruned in early summer before the weather gets too hot.

The soil of your Red Mandevilla needs to be slightly acidic and should also have good drainage so that you do not have root rot, which would prevent your plant from blooming properly. The soil of your Red Mandevilla should not get wet or saturated with water.

Red Mandevilla is a very hardy plant that can thrive in many different environments. The plant enjoys full sunlight but can do just fine in partial shade. It is hard enough to be planted outside and will flower throughout summer.

If you choose to grow your Red Mandevilla as a houseplant, bring it outside for the spring and summer months so that it gets enough sun and will bloom abundantly.  The plant thrives best when temperatures stay at least 70 °F (21.1 °C).

In addition, give your Red Mandevilla plenty of water and fertilize once every two weeks or so with a water-soluble high nitrogen fertilizer during the blooming season.  Red Mandevilla can be grown from cuttings, but it is best to grow the plant from seed in the spring and summer.

If you choose to use Red Mandevilla as an annual, then it must be planted in the spring. Make sure that your plants receive direct sunlight throughout the day.
