How to Grow a Mandevilla Plant


The Mandevilla (Mandevilla sanderi) is a showy vine native to Brazil that produces pretty flowers ranging from white to red. You can grow it as an annual in climates where the temperature drops below 65 degrees Fahrenheit; if you live in USDA climate zone 11 or higher (Hawaii and other tropical locations), you can grow it outdoors as a perennial---it will bloom all summer. Because it grows well in containers, you can move it indoors for the winter in cooler climates.

Growing a Mandevilla Vine

Step 1

Prepare a planting area where there is partial shade. Dig in one or two shovelfuls of peat moss and sand and then set your Mandevilla in the planting hole and backfill with the soil you dug out. If you plan to grow it as a houseplant, mix peat moss and sand with a good potting mix and then keep your plant in a room that has bright indirect sun.

Step 2

Set up a trellis for your Mandevilla or grow it against a fence or wall, where it will receive support for its rambling vines.

Step 3

Pinch off unruly branches to keep the plant well trained and compact.

Step 4

Allow your Mandevilla to dry out thoroughly between waterings. When you do water, run your hose on a slow drip and let it soak the roots for half an hour or longer.

Step 5

Fertilize your Mandevilla every two weeks during spring and summer. Use a plant food high in phosphorus---an N-P-K ratio of 10-20-10 is recommended.

Step 6

Spray your Mandevilla with insecticidal soap if mealybugs, spider mites or scale insects attack it.
