How to Grow Mandevilla Vine Flowers


Mandevilla is a spring-flowering vine native to Brazil. The trumpet-shaped pink or white flowers bloom abundantly throughout the summer against a background of evergreen foliage, with vines climbing up to 10 feet in height. The Mandevilla vine flower is hardy in USDA growing zones 9 through 11, but in zone 8 the vines can be killed back by frost and will grow back the following spring. This lush flowering vine is relatively easy to grow and care for, making it a popular vine for warmer climates.

Step 1

Grow your mandevilla vine flower in a location that receives full sun daily for the most abundant flowering. The plant will tolerate some partial afternoon shade in extremely hot climates. Use a well draining soil in the garden bed, adding some builder's sand to the soil before planting. Builder's sand is clean sand that you can buy at home improvement and gardening centers.

Step 2

Water the mandevilla regularly to keep the soil moist, but never soggy. Watering deeply two or three times per week is sufficient. Use a soaker hose, or garden hose with the water trickling out slowly, for best results.

Step 3

Feed your fast-growing mandevilla vine with a liquid, water-soluble fertilizer twice a month. The fertilizer should have a high phosphorus content (such as a 5-10-5 fertilizer)--phosphorus being the middle number on the bag of fertilizer.

Step 4

Train the vine to climb up a trellis, pole or fence. Tie the mandevilla vines to the support using cut nylon pantyhose. Retie as the vine grows.

Step 5

Pinch off 1/4 to 1/2 inch growth from the tips of the plant to ensure a bushier and healthier vine. Do this throughout the growing season--from late spring through the summer.

Step 6

Apply a 2-inch layer of mulch around the base of the vine to help control weeds, retain moisture in the soil and keep the roots insulated during winter. Use shredded bark, straw or chopped leaves as mulch and reapply each spring, as needed.
