Overview

Mandevilla plant, sometimes called dipladenia, is a tropical perennial valued for its long, pendulous vines, ornamental flowers and ease of cultivation. The plant blooms during early summer and fall, producing numerous flowers in shades of white, yellow and pink, depending on the variety. The plant is ideal for hanging containers, where the long vines can trail over the sides. Native to Central and South America, mandevilla plant requires consistently warm temperatures and cannot survive outdoors in most regions of the United States. Because of its tropical origins, gardeners typically grow the plant indoors throughout the country.

Step 1

Keep mandevilla plant in a location that receives bright, indirect sunlight throughout the day, such as an east-facing window. Maintain a constant temperature of 70 degrees F or higher during the day and 60 to 65 F degrees at night.

Step 2

Water once every five to seven days during spring, summer and fall to keep the soil consistently moist, but not soggy. Soak the growing medium until water begins to exit the bottom of the container, and then drain away all excess. Reduce watering frequency during winter to once every two weeks, allowing the soil to dry considerably between applications.

Step 3

Feed mandevilla plant once every two weeks during the spring and summer months using a high-phosphorous 10-20-10 NPK fertilizer. Apply following the directions described on the package for the best results. Do not fertilize during the fall and winter months.

Step 4

Remove any dead, damaged or diseased leaves whenever possible to improve the plant's health and appearance. Pinch off the undesirable foliage at its point of origin to minimize damage and prevent the development of disease.

Step 5

Re-pot mandevilla plant once every two to three years, or whenever the plant appears to have outgrown its current container. Increase the size of the container by at least 2 inches and use a fresh growing medium made of one-part peat moss, one-part coarse sand and one-part potting soil.

Tips and Warnings

  • Some portions of the mandevilla plant are toxic. Keep in a location not accessible by small children or animals.
