This is how you can safely overwinter the wonder flower

Don't dig up tubers too soon - Here's how to do it right

At the end of the flowering period, the miracle flower is far from resting. Now she would like to move the remaining nutrients from the leaves into the tuber as an energy reserve for the next season. Do not dig up the tubers until the leaves have completely yellowed. If temperatures regularly drop below 10 degrees Celsius at night, dig up the tubers and cut off shoots and roots.

So the miracle flower gets through the cold season safely

All you have to do is knock the earth off the dug up tubers, as a shower head could cause rot. How to properly overwinter the plants:

  • The winter quarters are dark, with temperatures between 5 and a maximum of 10 degrees Celsius
  • Place the miracle flower bulbs next to each other on a lattice or wooden shelf
  • You can choose to put it in a box in sand, sawdust or peat dust

Until the start of the planting season, rotate the tubers every 2 weeks and check the epidermis for rot or pests. If the air in the room is very dry, spray the plants a little with soft water from time to time to prevent them from drying out.


A lovingly cared for wonder flower develops a strong root system over the course of the season. You should therefore first plant the tubers in a pot with several openings in the bottom or in a plant basket (€ 14.11 on Amazon *) as used for pond plants. Only then do you plant the miracle flower in the bed from mid-May. This trick makes the autumn digging a lot easier.
