How to Propagate a Mandevilla Plant

Overview

The semitropical mandevilla plant produces pink to rose colored flowers on a twining vine. A moderately rapid-growing plant, it grows well in sunny regions, such as Florida, and tolerates coastal conditions but does not do well in cold climates. As with other vines, the mandevilla plant propagates easily through cuttings---taking a piece of stem from a parent plant to create an entirely new mandevilla plant.

Step 1

Cut a 6-inch healthy stem tip from a mandevilla plant during late spring or early summer. Sanitize the blade with rubbing alcohol before cutting. Make the cut at a 45-degree angle.

Step 2

Remove leaves from the bottom half of the stem cutting, wet the cut end and dip it in rooting hormone, covering about ½ inch of the stem.

Step 3

Plant the stem cutting, about 2 inches deep, in a small pot filled with equal amounts coarse sand and peat moss. Place several cuttings, if desired, in the same pot and space about 3 inches apart.

Step 4

Water thoroughly, allow the water to drain, and cover with a plastic bag to create a greenhouse. Keep in indirect sunlight at about 70 to 75 degrees F, until the cutting takes root, which will take about four weeks. Once the roots develop, the new mandevilla plant will be ready for replanting.
