Mandevilla Care

As long as you provide the proper growing conditions, Mandevilla is rather simple to maintain.

If you want your vines to thrive, you’ll need to provide them with plenty of sunshine, warmth, and moisture.

Be sure to water and feed your plant regularly throughout the growing season.

In early spring, pull back the stems of these vines to encourage a bushier growth pattern.

In order to encourage their natural vine growth, you need to supply them with some sort of trellis or another support system. Hanging baskets are a terrific place to display vines.


At least six hours of direct sunlight are required on most days for these vines to thrive and flower.

The afternoon sun in the height of summer can be oppressive, but they can endure a little shade and may even prefer it.

The ability to shift the plant out of the hot sun when needed is an advantage of cultivating Mandevilla vines in containers.


Slightly acidic soil with plenty of organic matter is ideal for growing Mandevilla vines. Peat moss, sand, and leaf mould make an excellent potting mix.

Ideally, the soil should be slightly acidic to neutral, although it can also handle slightly alkaline soil.


The Mandevilla species, unlike many other blooming plants, can endure moderate dryness and continue to flower.

However, they prefer a constant degree of moisture, so try to keep the soil damp but not waterlogged.

Slowly water the plant to allow the soil to absorb the moisture, and spray the leaves to deter pests and increase the humidity in the area.

Humidity and Temperature

Temperatures and humidity must be just right for these plants.

No lower than 50 degrees Fahrenheit at night may be tolerated by Mandevilla plants when they are planted outside.

Even in a dry area, spraying your plants periodically can assist maintain humidity levels.


In the spring, use a slow-release, balanced fertilizer on your vine.

Instead, you might apply a half-strength liquid fertilizer every two weeks from spring through fall.

Compost can be added to the soil to boost its nutritional value.

Growing Mandevilla Year-Round

Mandevilla is commonly thought of as an annual, although it is actually a perennial that is extremely vulnerable to frost damage.

Bring your Mandevilla plant indoors for the winter when the temperature drops below 50 degrees Fahrenheit (10 degrees Celsius).

Prior to bringing in your Mandevilla flowers indoors, be sure to thoroughly inspect the plant for pests and treat these bugs. Trim the plant back by up to one-third if necessary.

Make sure to put your Mandevilla vine in a spot with bright, indirect light once you’ve brought it indoors. When the soil feels dry to the touch, water the plant.

Move your Mandevilla plant outside in the spring, when the temperature is typically over 50 degrees F. (10 C.). Remove any dead leaves.

Potting and Repotting Mandevilla

You should only use a container that is slightly larger than the root ball of your Mandevilla plant when you initially pot it.

Until the plant’s root system has grown sufficiently, a container that is too large may lead it to spend more energy building roots than growing blossoms.

To avoid root rot, make sure the pot has plenty of drainage holes.

Repotting is necessary if you notice roots poking through the container’s sides. Mandevilla grows quickly, so you should expect to repot them every year in the spring.

It’s a good idea to go up a pot size if you need to. Take out the root ball from the old container and place it in the new one.

Then, replace the old potting mix around the root ball and thoroughly water it.

Common Pests

In general, Mandevilla plants are not plagued by any major illnesses. In addition, they can attract red spider mites and other pests, such as scales, white flies, and aphids.

Apply insecticidal soap or horticultural oil (like neem oil) continuously until all signs of infection have passed if you have an infestation. Neem oil is an excellent choice.

How to Get Mandevilla to Bloom

There are a few parameters that your Mandevilla plant needs in order to produce a lot of blooms each summer.

First and foremost, if you want your Mandevilla plant to bear the greatest fruit, it needs enough of light.

Planting your Mandevilla in a pot allows you to move it around and “chase” the sun if your landscaping doesn’t have a single area that gets 6 to 8 hours of sunlight daily.

For your Mandevilla to blossom, you’ll also need to fertilize it properly.

During the growing season, apply a phosphorus-rich fertilizer to the plant every two to three weeks.

Those who live in arid climates should consider fertilizing every two weeks, as the fertilizer will be flushed through the soil more quickly because of the regular watering.
