Characteristics of dipladenia or mandevilla
The first thing to say about the mandevilla, dipladenia or Chilean jasmine , as a precaution, is that this pretty climbing plant is toxic. It is not a problem to the touch, but it should not be ingested under any circumstances. Take this into account if you have pets or small children, and keep it out of their reach to avoid accidents.
Having already made the safety recommendation, we can say that it is a tropical plant that has its origin in South America, with evergreen leaves of bright green color and large and showy flowers in white, yellow, pink and red tones.
It is usually grown in pots, and although it is a climber it does not have tendrils and does not reach heights of more than 5 meters, so it can be pruned to keep small sizes.

Dipladenia or mandevilla: basic care
In this gardening guide we give you the basic care of dipladenia or mandevilla :
Location and brightness
Mandevilla can be grown both indoors and outdoors, but it needs light, heat and a humid environment, as with many tropical plants. Outside, place it somewhere where it receives partial sun, ideally during the morning, but never directly in the hours of greatest intensity. Indoors, look for a very bright room, but where it is protected from direct light in the hottest hours. Never place it next to heat sources such as kitchens or radiators, or in areas with drafts.
Both indoors and outdoors, it is good that you place it next to something like a trellis or pole that it can hold on to to grow.
Soil and compost
This plant needs a well-drained soil to avoid waterlogging, which makes it susceptible to attack by pests and diseases. Use black peat with coconut fiber as a substrate if you plant it in a pot. In any case, limit yourself to organic fertilizers for the plant. Compost, bokashi, and guano work well.
Irrigation of dipladenia
You should try to keep the soil of the mandevilla moist but not flooded. This means that, in summer, you will usually need to water it between two and three times a week, while the rest of the year it will be enough with once a week or even less. If in doubt, try sticking a toothpick in the dirt. If when you remove it, it does not have soil attached, it means that it is dry, and therefore you can water.
Pests in dipladenia
This plant can be attacked by mealybugs and spider mites. For mealy bugs, a cotton swab or swab dipped in soapy water is enough. For spider mites, spray the plant with potassium soap or neem or neem oil.
Pruning of the mandevilla
If you don’t want your mandevilla to grow too large or you just want to keep it healthy, prune it between spring and summer. Trim stems that are getting too long, and be sure to remove any wilted flowers.
Mandevilla care in winter
This plant is quite susceptible to cold. Even indoors, if the temperature falls below 10ºC it will begin to lose its leaves, and it is very possible that it will not survive cold winters if care is not taken with it. You can put glasses of water around the mandevilla so that the environment remains humid around it, and even wrap its pot in a thermal blanket for gardening use, although taking care to keep the drainage holes free.
How to make dipladenia or mandevilla bloom
If your Chilean jasmine or dipladenia does not bloom in spring and summer, it is probably because one or more of its needs described above are not being met. Most likely, the plant is receiving too little or too much light, or is near an area with drafts or nearby artificial heat sources.
Go over the points one by one and your mandevilla will soon produce its big and beautiful flowers .
