This vine lives up to five years in the best conditions.
Mandevilla Care
Here are the main care requirements for growing mandevilla.
Light
Mandevilla likes the sun more than shade, but it can tolerate partial shade.

However, they might even appreciate shelter from the hot afternoon sun at the peak of summer.
Soil
Mandevilla vines need sandy, well-draining soil with plenty of organic material mixed in.
A goodpotting mixis a combination of peat moss, sand, andleaf mold.
The Spruce / Phoebe Cheong
A slightly acidic to neutral soil pH is best, though the plant can also tolerate slightly alkaline soil.
Water
Unlike many flowering plants, the mandevilla species can withstand some dryness while continuing to flower.
Temperature and Humidity
These plants require warm temperatures and high humidity.
The Spruce / Phoebe Cheong
If you live in a dry climate, regularly misting your plants will help to keep humidity levels up.
Fertilizer
Fertilize your vine in spring with aslow-release, balanced fertilizer.
Alternatively, you could use a liquid fertilizer at half-strength every two weeks from spring to fall.

It also can be helpful to mix some compost into the soil to improve nutrition levels.
Types of Mandevilla
There are more than 100 species within theMandevillagenus.
To do so, water the plant well so it’s hydrated and not further stressed by your trimming.
Cut any vines back to just above a set of leaves using a sharp, clean pair ofpruners.
verify the pot has ample drainage holes to help preventroot rot.
Repot mandevilla once you see roots creeping out of the container.
This fast-growing plant likely needs to be repotted one pot size up annually in the spring.
Before bringing your plant indoors, cut it down a bit to let it rest.
Place the container in bright, indirect light and water it when the soil is dry to the touch.
Mist it regularly or place it on a tray of pebbles filled with water.
Return it outdoors in the spring when temperatures rise above 50 degrees Fahrenheit.
Common Pests
Mandevilla plants generally dont have any serious problems with diseases.
What do Mandevilla Flowers Look and Smell Like?
Some species within the genus have smaller, more plentiful blooms while others have fewer, larger blooms.
Their ovate leaves are usually a glossy green.
The flowers have a mild, sweet scent.
How to Encourage More Blooms
Mandevillas require ample light to produce the most buds.
Proper fertilizing is also an important factor in getting your mandevilla to bloom.
Feed the plant every two to three weeks during the growing season with a fertilizer high in phosphorus.
Here’s what to do if you spot the following issues.
Too little water will make leaves yellow and curl.
Repair the plant by watering it from the bottom, not the top.
Do this by immersing the pot in water for a few minutes so water reaches the roots.
Browning Leaves
A mandevilla with browning leaves has the opposite problem of yellowing leaves.
Try fertilizing the plant and scheduling consistent waterings.
Brown Spots on Leaves
Brown spots and browning leaves mean two different things with mandevilla.
Brown spots may indicate a case of a fungal disease called anthracnose.
Overly wet leaves can lead to this disease and lead to dropping leaves, as well.
Prune the affected leaves and treat the plant with a fungicide.
Mandevilla will grow back as tender perennials in mild climates.
In cooler regions, this vine is planted as an annual and typically grown in a container.
Mandevilla is a vine and will thrive if grown on a support such as a trellis.
