It's a pleasure to ask you this question.
I bought in Amazon some bulbs of different Begonias 1 month or so ago.
They had some branches but no leaves.
Although it is nearly Winter, I had to do something with it and I decided to plant it. Fortunately the Summer here in Dortmund, Germany is going good, so the plants are getting nice and green.
However, I'm really worried as the winter is coming and they don't survive to the cold and had no flowers yet.
How can I safe them? Bringing inside? Cutting? Let them outside till the cold kills them?
I can send you some photos later, if needed.
Thank you in advance!
