Burrowing
In addition to overwintering in the greenhouse, outdoor bonsai can be overwintered by burying it into the garden ground.
For this purpose, the bonsai pot is wrapped in a jute bale fabric. Then the bonsai is placed in a previously dug hole in the garden up to the 1st branch. The hole is then filled with soil.
A shady, wind-protected place is well suited, where the bonsai tree can remain from November to February.
In this video (in german) we show you how to do it.
