How to Grow Dipladenia - Planting & Caring

Growing Easiness

Is it easy to grow Dipladenia plant? Unless you are an experienced gardener, it is best to choose a different plant. Dipladenia is not an easy plant to take care of and is often difficult for beginners. The plant does not like to be moved around and prefers to stay in one place. It also does not like to be watered too often or too little. If you are not careful, the plant can quickly die.

Plant Size

How big can it be? The unpruned plant can reach a size of 3-5 m. If you want to control the size, then you need to prune it to 45 cm.

Growth Rate

How fast is the growth? The reason why Dipladenia plants grow so fast is that they are not pruned.

Family Apocynaceae
Origin Tropics of South America.

Lifespan, Perennial or Annuals

How long is the lifespan? The plant has a lifespan of around three years. However, with the right care, they can live much longer. Dipladenia plants need full sun and well-draining soil to thrive. They should be watered regularly, but not allowed to sit in water. Fertilizing every few weeks will help keep them healthy and blooming.

Ideal Temperature

What is the ideal temperature? The plant is from the tropics so it loves hot weather. In the summer, the plant should be in temperatures from 64.4 to 69.8 degrees Fahrenheit. In the winter, the plant should be in temperatures from 55.4 to 59 degrees Fahrenheit. The plant also needs high humidity levels, so if you live in a drier climate, you may need to mist the plant daily or put it in a humid room.


What about the humidity? Since the Dipladenia plant is native to tropical regions, it requires high humidity to feel comfortable. The air in our homes is usually too dry for it, so the plant should be regularly sprayed with water at room temperature. You can also keep the pot in wet peat or claydite.

Light Requirement

What amount of light this plant needed? The Dipladenia plant grows best in bright, diffused light. It can grow in a south-facing window with shading from east and west windows.

Soil Composition

What is good soil for Dipladenia? Sometimes, people are not sure what type of soil is best for their Dipladenia plant. Here is some information that might be helpful. Fertile, well drained soil is suitable. For every two parts of leafy land, add one part of sod land and one part of peat land. You can also add a half part of coarse sand or perlite. If you want, you can also use one part of peat land, one part of humus earth, and one part of coarse-grained sand. No matter which option you choose, make sure to use a pot with a hole.

Watering Time

How much I must water Dipladenia? Because it is a tropical plant, it needs more water than other plants. In summer, water it 2-3 times a week. In winter, only water it when the soil is dry.

Fertilizing and Nutritient

About fertilizer. Sometimes, people ask me what kind of fertilizer I use for my Dipladenia plant. Here is my Dipladenia plant fertilizer recipe that I use from May to September. I use liquid fertilizer and dilute it twice. I use it about 2 times a week.


How to reproduce Dipladenia? The reason I choose this subject is because I have recently been given a mini Dipladenia plant and I am interested in how to make it reproduce so that I can have more. I found out that Dipladenia plants reproduce best from apical cuttings taken in spring and planted in a mini-teplichke. The mini-teplichke is a small container that is constantly sprinkled and aerated. To prepare the cutting, a stalk 8-10 cm long is taken from the plant and the lower pair of leaves are cut off. A small hole is then made in the soil of the mini-teplichke with a pencil and the cutting is planted in the hole. The container is then covered with glass. It is important to maintain a temperature of about 69,8 ° F for the plant to thrive. It is also good to put the container on the radiator. The glass is removed after about 3 weeks. The plants are then planted in a constant soil mixture. Dipladenia plants usually blossom in the same year.


Why Dipladenia won't bloom? The blooms last for about two weeks and come in colors like pink, red, and white. They are bell-shaped and add a touch of elegance to any garden or home.

Transfer or Repotting

How much I must water Dipladenia? Common ly, every year in the spring, the pot must be voluminous, deep enough and about 25 cm in diameter. In a tight pot, the plant feels bad. For adult plants, the topsoil can be replaced. Young plants grow 2-3 times in height a year.

Caring The Dipladenia

How to care the plant? Although young shoots of the Dipladenia need support, high air humidity and proper pruning after flowering (leaving about 5 cm if the plant is grown as a bush or cutting off the side shoots and leaving the main one long if the plant is grown as an ampel) are necessary for the plant's health. The best place for the Dipladenia during summer is in the garden or on the balcony where it can get fresh air.

Pests & Challenges

What is the challenge when caring Dipladenia plant? Common problems are the appearance of pests, such as red spider mites, scale insects, mealybugs. If in winter the leaves turned yellow and fall off the plant, it is most likely, with the cold, the phenomenon is due to the summer too dry air. The plant grows poorly and does not blossom due to lack of nutrients.

Toxic & Poisonous Type

Are Dipladenia poisonous? The Dipladenia is a genus of about 25 species of flowering plants in the family Apocynaceae, native to Mexico, Central America, and the West Indies. The genus includes both evergreen and deciduous species. They are climbing plants, with twining stems bearing opposite leaves, and large, trumpet-shaped flowers. Some species are grown as ornamental plants. The juice of the plant is toxic and one should be careful with it.
