Caring for Dipladenia: Simple Tips for Success

To ensure your dipladenia, a captivating climbing plant native to Central American countries, thrives, follow three straightforward tips: find a bright location, maintain regular watering in summer, and perform autumn pruning. Recognizable by its bell-shaped flowers in white, pink, and red hues, dipladenia, or mandevilla, belongs to the Apocynaceae family and serves as an exquisite ornament for balconies, terraces, pergolas, and gardens. With nearly two hundred varieties available, such as the indoor-suited dipladenia rosea and the outdoor-friendly dipladenia williamsii, caring for this plant is a breeze.

How to Cultivate Dipladenia:

Plant Characteristics:

  • Dipladenia boasts generously sized, bell-shaped flowers, up to 5 cm in diameter, and vibrant glossy green leaves, making it a striking tropical liana.

Climate and Location:

  • Dipladenia thrives in mild climates, with an ideal temperature around 21°C. Protect it from scorching heat in summer and maintain a temperature between 10 and 14°C during winter. Place it in a bright area indoors or outdoors, adjusting based on seasonal changes.

Soil and Fertilization:

  • Provide a well-balanced soil mix consisting of garden soil, peat, sand, and leaves, rich in organic substances. Supplement with humus or fertilizer during spring and summer.


  • Water dipladenia frequently, especially in summer. Allow the soil to dry between waterings, and enhance humidity by placing wet gravel in the saucer and misting the leaves in the late evening.


  • Dipladenia blooms from late spring to autumn, with flowers continuing to develop throughout the season. Ensure a cool winter environment to promote abundant flowering in summer.


  • Perform pruning in autumn during full vegetative rest to encourage lateral growth and shape the plant.

Troubles and Diseases:

  • Combat red spider mites promptly with specific products if leaves turn yellow and exhibit small dark dots. Increase humidity to deter mite proliferation.
  • Address cottony scale insect infestations by using denatured alcohol-soaked cotton balls or specific insecticides on whitish spots.
  • Prevent brown spots caused by insufficient watering or excessive sun exposure. Adjust placement for hanging leaves, especially in colder seasons, to mitigate potential temperature-related issues.
