Mandevilla (diplatia): growing in the garden and in a pot

What is diplasia? It is an evergreen climbing plant that is fast growing, hardy, and blooms continuously from spring to autumn. Blooming diplatia is very decorative. Blooms on balconies, terraces and flower beds all summer. Grow in the form of a branched vine or bush. Attracts flower growers with bright flowers. It loves warmth, high humidity, indirect lighting and is generally not an easy plant to grow indoors. But they are so beautiful that it is worth making a little effort.

Diploidia flower: description

Curly diplatia is native to Central and South America. Belongs to the Kutrovye family (Apocynaceae). There are about 30 evergreen, usually climbing species. In open ground, the liana can reach more than 3-4 meters.

Thin stems grow quickly. The leaves are glossy, lanceolate, about 6 cm long and 4 cm wide. From May to November, the plant produces a cascade of large tubular flowers, about 7 cm in diameter, collected in a brush.


The lifespan of one flower is 2-4 weeks. Withered flowers fall off on their own. Depending on the species, the color varies from white-yellow to pink and purple-red. Thick roots serve as a reservoir of moisture during periods of drought.

Diplosion in the garden, in places with mild winters, can grow in open ground. Considered as an annual garden plant.

Diplomacy: care

Mandevilla loves bright places, even sunny ones. It is placed in a well-lit area, but not in direct sunlight: this can burn the leaves and make the flowers much smaller. It also grows well in partial shade. In a completely shaded area, it produces few flowers and many leaves.

Diplosion in the garden

The ideal temperature for flowering is around 20°C. Plants must be protected from drafts and wind.
Diplatia does not tolerate frost, it should not be exposed to temperatures below 5-8 ° C. In places with mild winters, it is grown outdoors, but in this case, it loses leaves from the cold, which reappear in spring. In mild climates, plants may remain outdoors, forming climbing shrubs for many years.
In areas where winter temperatures fall well below freezing, the plant should be treated as an annual and stored in a frost-free and bright room.

Note! During the winter, temperatures should ideally be around 13°C. They need dormancy during the winter and so are best kept around this temperature to see many flowers in the spring.

Plant propagation

From time to time they are watered with water to prevent complete drying. Then you can move it outside in the spring, when the danger of severe frosts has been eliminated.
Mandevilla prefers loose, well-drained soils that are very rich in organic matter.

Regular watering is necessary, but the plant does not require a lot of water, and easily tolerates short periods of drought. If they last too long, they threaten growth and flowering continuity.

Like all very floriferous plants, they need an important and constant fertilizer. For good Dipladenia plant care, it is very important to use a slow release fertilizer. Many fertilizers include a foliar application which usually gives excellent and immediate results.

Diploding: propagation by cuttings
The fastest way to get new seedlings is cuttings, when young shoots are cut in the spring. Three or four leaves are left on the cuttings. The lower leaves must be removed, sprinkled with a powder or liquid rooting agent from below. Placed in a peat substrate and covered with a plastic cup or bag.
The container is left in a warm place for a month and a half. At the same time, the greenhouse is regularly watered and ventilated.
When the cuttings are fully rooted, they are planted in separate containers. You can plant several stems in one pot to get a dense flowering crown. When cuttings, the vine blooms in the first year of a new life.

Diplosion pruning
It is advisable to cut the branches lightly in early spring or autumn so that the plant does not grow too much in the lower part. Branches should be cut very low, about 5 cm above the ground. This will allow the plant not to waste energy during the cold season, and will avoid the possible appearance of mold. Diplosion blooms on new branches that grow throughout the year. Therefore, it is good to carry out a good pruning every autumn.
If the plants were grown in the ground, it is best to wait until the night temperature reaches around 10°C to start explanting. Placed in containers for wintering in a cool room.

indoor plant

To maintain a decorative form, this flower needs a sufficient amount of moisture in the soil and air, timely top dressing and pruning.
Taking care of it is easy:

  • with sufficient lighting;
  • providing fresh air;
  • with frequent watering.


Diplomatic room

Location selection
Flowers need a lot of light, but they must be protected from direct rays by choosing the most illuminated windows in the entire apartment. You should not put them on the south window.

Support for a flower

Gradually increase the size of the container to encourage the growth of new and healthy roots. Care should be taken to securely support the stems.
In its natural environment, the vine develops within two meters. Under favorable growing conditions, it can reach the same length indoors.

Flower feeding is recommended at the beginning of the growing season, during the formation of buds and during flowering. Complex mineral fertilizers are applied weekly. Top dressing continues until the dormant period. In winter, Diplodace does not need good nutrition.

Diploidia: pests and diseases

Very resistant plants rarely become prey to insects or parasites. Sometimes these plants are attacked by spider mites, aphids and scale insects. Especially if they are exposed to direct sunlight and grow in too dry an environment. In this case, it is useful to move the plant to a less open and hot place and increase the humidity of the environment.

iplatia with yellow leaves

Yellow leaves may appear for several reasons.

One of the main reasons is improper watering. Dipladenia leaves can turn yellow either from too much water or too little water. With abundant watering of an earthen coma and the use of poor-quality soil, the roots rot.

With a lack of light, flowering is rare, and juicy greens become paler. Lack of light can cause insufficient photosynthesis and, as a result, yellowing of the leaves.

Other possible reasons why a plant develops yellow leaves may be due to the soil and the presence or absence of nutrients in it.

So that the leaves of diplatia grown in pots do not turn yellow, they should be transplanted once every 2-3 years. Transplantation is necessary to renew the soil with a large amount of organic matter.

If the air is too dry, exposed to direct sunlight, the leaves curl and dry.

Varieties of diplomacy

Mandevilla atroviolacea has a number of very popular cultivars. Group Sundaville (Sundavil), looks great in containers on balconies and terraces.

DIPLADENIA SANDERI with large pink flowers and large leathery oval leaves.
DIPLADENIA BOLIVIENSIS . Stems woody, branched. Abundant white flowers with a yellow center, rather small.

DIPLADENIA SPENDENS . Inflorescences consisting of 4-6 dark pink flowers with a yellow core. This is a very vigorous species.

The plant is poisonous. Therefore, special care must be taken in the presence of children and pets. It should also be taken into account that the juice can cause skin irritation, so it is better to use waterproof gloves when pruning or transplanting.
