How do I care for my dipladenia plant?

Updated February 21, 2017

The Dipladenia plant, also known as Mandevilla, is considered a shrub and is most often used in hanging baskets and trellises. Native to Paraguay, the Dipladenia or Mandevilla is a vine that grows fairly quickly and produces trumpet shaped flowers in a variety of colours such as pink, purple, yellow, and white.


The Dipladenia plant prefers warm water that does not have a high acid content. Therefore, if you rely on rain water to provide a drink for your plants, you must be extremely careful how much your Dipladenia plants receive. Too much water with too high of an acid content could kill the plant. When watering manually, make sure to thoroughly wet the soil each time you water and then wait until the ground is nearly dry before watering again.


Feed the plant once annually, in the spring. If using this method to feed, use a fertiliser that slowly releases the needed nutrients in the soil. If you want to use a simpler fertiliser, choose a water-soluble mixture and apply it every two weeks. The key thing to remember about fertilising or feeding is to never fertilise the plant in the winter.

Pruning and Propagation

Prune the Dipladenia during and at the end of the growing season. At the end of the season, plant the clipped shoots in pots and wrap the pots in plastic at the bottom. Keep the new potted shoots where warmth and water will combine to create a good deal of humidity. The ideal environment for growing Dipladenia is a humid environment. Therefore, even for established plants, provide enough light should to create warmth. Misting is also beneficial to create the ideal humid conditions for growing. However, avoid direct sunlight.
