What is Dipladenia Plant?

Dipladenia vs Mandevilla

A member of the flowering plants, this species is a native of South Africa. Most of the time, Dipladenia and Mandevilla plants are referred to as the same. However, there are differences between the two, although they come from the same family.

One distinction is the growth habit between the two plants. Dipladenia is a shrub-like plant having a bushy appearance with its stems trailing downwards. In contrast, Mandevilla plants are climbing up. It does need a support structure like a pole or stake.

Both plants produce colorful blooms in red, pink, or white. Mandevilla vines have bigger blooms and foliage than the Dipladenia plants, however, the latter does better in attracting hummingbirds.

Since Dipladenia has a bushier growth, it has a bulkier form.

How to Take Care of Your Dipladenia Plant?

Although the Dipladenia and Mandevilla species have slight differences in their growth pattern and appearance, they have the same care and maintenance requirements.

Best Potting Mix for Dipladenia

Dipladenia potting soil

Dipladenia plants require frequent watering especially if grown outside under the full sun. It’s crucial to keep the soil moist but not waterlogged. The key to achieving this is by using a potting mix that has a well-draining structure.

A combination of loam and sand is going to work well with a pH level ranging between 6.6 to 7.8. Provide plenty of organic material in the mixture so it will enjoy sufficient nutrients.

Lighting Requirement

Dipladenia light

Positioning your plant in locations with enough light is essential to achieve more Dipladenia flowers. This one loves exposure to the full sun so treating this as an outdoor plant with enough access to full sunlight is necessary. Nevertheless, do not subject Dipladenia under direct sunlight for extended hours, especially during midday.

On average, six and eight hours of light is needed. Just move the plant to shaded places once there’s the scorching heat.

Required Watering

Make sure to provide plenty of water through frequent watering. Do this, especially during the summer months when the weather is hot. Just make sure that the soil is draining any excess water to prevent root rot. We don’t want our Dipladenia plants to be sitting in overly wet soil.

To some extent, dipladenias can tolerate drought. So, you can let the soil dry for a while. However, ensure that this condition won’t be extended as this may cause wilting.

Temperature and Humidity

Humidity isn’t much of a concern regarding Dipladenia plant care. Luckily, this plant isn’t a picky one. However, when it comes to temperature, it should be above 65℉ (18.3℃). This plant is a tropical species that is acquainted in warm climates.

Dipladenia indoor temperature

Be mindful of temperatures drop below the threshold. If that happens, bring your plant indoors.

Fertilizing Dipladenia

To keep the plant healthy, regular application of fertilizer is needed. You can use any liquid plant food or slow-release fertilizer. Once or twice a month, feeding will do, but make sure to do this in Spring, during the growing season. This will boost the new growth of the entire plant.

Organic Fertilizer

During winter, you can give fertilizer a pass since your plant won’t need it anyway. Refrain from overfertilizing, as this can harm your Dipladenia.

Propagation of Dipladenia Plant

The best way to propagate Dipladenia plants is by using vine cuttings. Follow these steps:

  • Spot and choose a mature vine, cut it off (slant cut), and remove the leaves around. You may wash the leaking sap so the cut looks clean.

  • Dip the tip to the rooting hormone to speed up the root formation.

  • Plant it in a growing medium and water it well.

  • Please place it in a bright and warm area.

  • When new growth is visible, please wait until the foliage has flourished before you transfer it to a bigger pot.

How to Care for Dipladenia in the Winter

  • Bring potted plants indoors before the first frost. Choose a sunny window.
  • Cut back on watering, allowing the soil to dry out between waterings partially. Too much moisture can lead to root rot.
  • Stop fertilizing 6-8 weeks before bringing indoors. No nutrients are needed while dormant.
  • Maintain temperatures above 55°F. Cooler temps can damage the plant.
  • Prune away dead or damaged growth to keep a tidy appearance.
  • Check for pests like mealybugs and apply insecticidal soap if needed.
  • In spring, transition back outdoors after the risk of frost passes. Prune lightly, repot, and resume regular care.

The key things are providing ample light, reduced watering, proper temperatures, and pest monitoring while overwintering indoors. With the appropriate care, Mandevilla will thrive season after season.
