Sundaville's summer blossom magic has a good chance of a revival next year. A successful hibernation is possible under the right conditions. You can find out how the ambitious plan works here. The five most frequently asked questions are given a well-founded, compact answer here.

Are Sundaville Hardy?
The pompous Sundaville varieties are a direct descendant of the tropical-subtropical dipladenia species Mandeville sanderi. This origin results in a pronounced sensitivity to frost. Outside, the opulent summer flowers cannot hibernate, even with extensive winter protection.
When and how to concede Sundaville?
Modified care from the beginning of August prepares the Sundaville for the cold season. If the thermometer drops below the 10° mark, it is high time to move to the winter quarters. A pruning if necessary solves space problems at the winter location. How to properly tidy up a Mandevilla:
- Adjust nutrient supply: stop fertilizing from the beginning of August
- reduce water supply: water more sparingly from the beginning/middle of September
- Grant: at the latest at night-time temperatures of 8° Celsius (hang up the minimum-maximum thermometer)
- Cut as needed: if there is a lack of space at the winter location, cut back disturbing shoots
- clean up: remove dried, yellow leaves and wilted flowers
- Protection from ground cold: Place pot on wood or styrofoam to protect against cold feet
Examine shoots, leaves and substrate for pests and signs of disease. If you do find one, quarantine Sundaville first, where you control aphids, powdery mildew, and other problems.
How can Sundaville winter?
Evergreen Dipladenia from subtropical regions want winter quarters with lots of light and mild temperatures. If Sundaville finds a place with these basic conditions, winter can come:
- Flooded with light, with the possibility of shading against the blazing winter sun
- Mildly tempered with 10° to 15° Celsius
- Ideally a humidity of 50% to 60%
A supply of fresh air is desirable in winter, but should not be accompanied by cold draughts.
Which premises are suitable as Sundaville winter quarters?
Sundaville's list of suitable spaces for wintering is longer than the requirements suggest. For the strenuous journey through the cold season, a distinction must be made between different location qualities. The following list provides an overview:
First class winter quarters
- temperate conservatory
- heated greenhouse
- glass roof terrace with frost guard
- cool bright bedroom
Second Class Winter Rooms
- Garage with windows and frost guard
- Garden shed (€24.90) with heating option
- heated winter tent
- bright staircase
The wood class among the winter locations for Sundaville are areas with little light with temperatures between 15° and 18° Celsius. In this case, a plant lamp (€21.99) with a blue-red light spectrum should compensate for the lack of light.
What should be considered in winter care?
Modified care continues in winter, as begun in late August, in preparation for wintering. Do not apply fertilizer until mid-March. Water Sundaville as needed rather than at fixed intervals. If the plant keeps its foliage, it needs watering more often than when it is leafless.
tips
The mainstay in the cultivation of Sundaville is competent pruning care. At the end of the hibernation, subject the climbing plant to its central shape and maintenance cut. A beginner-friendly tutorial explains how to properly cut dipladenia.
