Find a bright location for it, water it often in summer and prune it in autumn. Three simple tips for taking care of your dipladenia, a climbing plant native to Central American countries that can also be grown on the balcony of your home.


Recognizable for its bell-shaped flowers in white, pink and red shades, dipladenia is an ornamental plant belonging to the Apocynaceae family and native to Central American countries. It is a climbing plant , used to embellish terraces and balconies, pergolas and gardens. There are almost two hundred varieties of dipladenia , or mandevilla , some of these are more suitable for growing indoors such as dipladenia rosea , while others are more suitable for growing outdoors such as dipladenia williamsii .

In any case , taking care of this plant is very simple , as long as you water it regularly in the hottest season, guaranteeing it a bright position and mild temperatures.

How to grow dipladenia

Characteristics of the plant

Dipladenia not only stands out for its bell-shaped and generously sized flowers (even 5 cm in diameter), but also for its intense glossy green leaves, which do not go unnoticed. Considering its origin, it is not surprising that this plant is a real tropical liana adorned with magnificent flowers and which, providing it with the right support, can embellish a corner of the garden or terrace of the house.

Climate and location

Dipladenia appreciates the mild climate and cannot tolerate temperatures that are too low or too high. The ideal temperature in which to grow is around 21°C, for this reason in summer it should be protected in the shade if the climate tends to be scorching hot. In the winter months, however, dipladenia should be kept at a temperature between 10 and 14°C, illuminated by natural light, in a place sheltered from the cold. The best position in which this plant can be placed is a bright area , both inside and outside the house, according to the seasons and temperatures.

Soil and fertilization

The ideal soil for the correct development of this climbing plant is a mix of garden soil, peat, sand and leaves . The important thing is that the soil is rich in organic substances, otherwise you can add humus or fertilize in spring and summer.

When to water it

Dipladenia needs to be watered often, especially in summer. Between one watering and another, let the soil dry, without worrying too much about the plant which can easily tolerate short periods of drought. To guarantee humidity, you can put wet gravel in the saucer and spray the leaves with water in the late evening.


The flowering period of dipladenia is late spring and the good news is that the flowers continue to develop until autumn arrives. Make sure to place the plant in a cool place in the winter, to enjoy abundant flowering in the summer.


Dipladenia must be pruned in the autumn season , in full vegetative rest. Pruning the plant helps to favor the lateral development of branches, leaves and flowers, as well as to give the desired shape to the plant itself.

Troubles and diseases

If you notice that the leaves of your dipladenia are starting to turn yellow and are covered with small dark dots, it could mean that it has been attacked by red spider mites , a mite that can also become harmful if you don’t intervene promptly with a specific product. Another intervention you can do is to increase the humidity of the plant because it is precisely the dry air that favors the proliferation of this mite.

If you notice whitish spots instead , the attack is probably coming from the cottony scale insect which you can remove with a cotton ball soaked in denatured alcohol or with a specific insecticide if the infestation is already extensive.

If brown spots appear , perhaps the plant has been watered little or has been exposed to direct sun. Also pay attention to hanging leaves : if it happens in the colder season it could be a temperature problem (too low). Then move the plant to a more sheltered place.
