Sundaville's summer floral magic has a good chance of a revival next year. Successful wintering is possible under the right conditions. You can find out how the ambitious plan succeeds here. The five most frequently asked questions receive a well-founded, compact answer here.
How to winterize Sundaville?
In order to successfully overwinter Sundaville, they need a bright, frost-free winter quarters with temperatures between 10° and 15° Celsius. Reduce the nutrient supply from the beginning of August and the watering from mid-September. Move the plant away before temperatures drop below 10° Celsius.
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. The opulent summer flowers cannot overwinter outside, even with extensive winter protection.
When and how should you vacate Sundaville?
Modified care from the beginning of August prepares the Sundaville for the cold season. If the thermometer drops below 10 degrees, it is high time to move to winter quarters. Pruning if necessary solves space problems at the winter location. How to properly put away a Mandevilla:
- Adjust nutrient supply: no longer fertilize from the beginning of August
- Reduce water supply: water more sparingly from the beginning/mid of September
- Putting away: at the latest when nighttime temperatures reach 8° Celsius (hang up a minimum-maximum thermometer)
- Cut if necessary: if there is a lack of space at the winter location, cut back disturbing shoots
- Cleaning: remove dried, yellow leaves and wilted flowers
- Protection from cold floors: Place the pot on wood or Styrofoam to protect against cold feet
Examine shoots, leaves and substrate for pests and disease symptoms. If you find what you're looking for, first quarantine Sundaville where you'll fight aphids, mildew, and other problems.
How do Sundaville winter?
Evergreen Dipladenia from subtropical regions want a winter quarters with lots of light and mild temperatures. If Sundaville finds a place with these basic conditions, wintering can begin:
- Flooded with light, with shading option against the blazing winter sun
- Mild temperature at 10° to 15° Celsius
- Ideally a humidity of 50% to 60%
Fresh air supply is desirable in winter, but should of course not be accompanied by cold drafts.
Which rooms 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
- tempered winter garden
- heated greenhouse
- glass roof terrace with frost monitor
- cool, bright bedroom
Second class winter rooms
- Garage with windows and frost monitor
- Garden house with heating option
- heated winter tent
- bright staircase
The wood class among the winter locations for Sundaville are low-light locations with temperatures between 15° and 18° Celsius. In this case, a plant lamp (€89.00 on Amazon) with a blue-red light spectrum should compensate for the lack of light.
What should you pay attention to when caring for the winter?
In winter, the modified care continues, as it began at the end of August in preparation for winter storage. Do not apply fertilizer until mid-March. Water Sundaville as needed rather than at fixed intervals. If the plant retains its leaves, watering is required more frequently than when it is leafless.
Tip
The mainstay of Sundaville cultivation is expert pruning care. At the end of the winter period, give the climbing plant its central shape and maintenance pruning. A tutorial suitable for beginners explains how to cut dipladenias correctly.
