Help, my Dipladenia froze to death!

Can I still save my Dipladenia?

If your Dipladenia got too cold for a short time, you can try to rescue it. However, it does not necessarily have to be successful, because the Dipladenia is very sensitive to cold. Move the Dipladenia to a warmer place, for example in a winter garden, and cut back the plant.

If some of the cut shoots are obviously undamaged, use them as cuttings and grow new plants from them. Presumably these young plants have even greater chances of survival than the old plant.

How do I successfully overwinter my Dipladenia?

Since the Dipladenia can be damaged at temperatures below 8 ° C, bring this plant to its winter quarters at the end of September or beginning of October. For example, a heated greenhouse or a bright winter garden with temperatures between 9 ° C and 15 ° C is suitable. If you overwinter the Dipladenia in a dark cellar, then it will almost certainly not bloom next summer.

The Dipladenia should be bright and neither too warm nor too cold in winter so that you can enjoy the beautiful funnel-shaped flowers in the next season as well. This means that the Mandevilla is not an easy winter guest. For this reason, only the particularly beautiful or high-priced specimens are often overwintered.

The essentials in brief:

  • not hardy
  • very sensitive to cold
  • takes damage at temperatures just above 0 ° C
  • overwinter at 8/9 ° C to 15 ° C
  • be sure to overwinter in light
  • slowly get used to the sun and outside temperatures in spring


If your Dipladenia has obviously been damaged by the cold, an attempt to rescue it will not be very successful. Make sense of the damage and act early next fall.
