Dipladenia, also known as mandevilla or sundavilla, is a creeper of South American origin, cultivated for its splendid flowers, which it produces throughout the summer.
This climber does not produce tendrils, but develops wrapping itself around the supports that we will have to supply; if we do not place our dipladenia near a trellis or a reed it will develop downwards.
It is generally cultivated in a pot, in a good rich and well-drained soil; prefers bright locations, but not exposed to sunlight for too long, especially during the hottest hours of the day. The sundavilla variety was especially selected for vegetating well even in full sun.
From March to April, until the end of autumn, they are watered regularly, waiting for the ground to dry out between one watering and another; during the cold months the plant goes into vegetative rest, so it must be sheltered in a place sheltered from freezing, avoiding watering it. To survive these plants need winter minimums close to 8-10 ° C, then place them in a stairwell, or in a cold greenhouse.
Before storing them for the winter, it is a good idea to shorten all the rams that have flowered up to 7-10 cm from the ground, so as to favor the development of new branches the following spring.
