How to Grow Mandevilla Plants

Overview

The mandevilla plant is a colorful tropical vine with woody stems and large pink blooms that sometimes measure up to 4 inches across. Mandevilla attaches itself to almost any climbing structure provided and can quickly reach heights of up to 10 feet. It is hardy only in USDA Zones 9 to 11, as it cannot tolerate temperatures below 45 degrees F. In other areas, you can plant it in a container and bring it indoors when cool weather arrives. Mandevilla does best in partial sun outdoors and muted sunlight when grown inside.

Step 1

Fill a growing container with one part potting soil, one part builder's sand, and one part peat moss. Plant the mandevilla at the same level it was previously growing and water until the soil is very moist.

Step 2

Place the container outdoors in a location that receives partial sunlight during summer, once nighttime temperatures no longer dip below 60 degrees F. Water the plant whenever the soil feels dry to the touch.

Step 3

Feed every other week with 10-20-10 fertilizer during the spring and summer months.

Step 4

Stop fertilizing and reduce watering in early fall. Inspect the foliage for signs of disease and remove any leaves that are dead or damaged. If you find signs of pest infestation, treat with insecticidal soap.

Step 5

Bring the plant indoors and place in a location that receives plentiful light, but not direct sun. Continue to water minimally throughout fall and winter.

Step 6

Prune off old stems in late winter or very early spring. Resume regular watering and feeding in early spring.
