Although the mulberry tree, which is related to figs, comes from the subtropics, it is considered hardy. With a special growth form or extra large fruits, you are sure to find the ideal eye-catcher for your home garden.
It is disputed how many species of mulberry tree there actually are, because hybrids are increasingly being cultivated. In addition to some hybrid species, there are mainly three types of mulberry tree in Germany:
- Morus alba, the white mulberry
- Morus rubra, the red mulberry
- Morus nigra, the black mulberry
While the first two species are hardy, the black mulberry should be protected from frost and cold winds. It thrives best where wine can also be grown. The white mulberry tree and the red mulberry are hardy, depending on the variety down to minus 15 or 20 °C.
How to protect your mulberry tree in winter
The hardy varieties of the mulberry tree should also be protected in the first two to three years when temperatures are severely below zero. A thick layer of brushwood, straw or leaves should suffice, or a few burlap sacks. Remove the winter protection as soon as the temperature rises to around +/- 0 °C again, this will prevent mold from forming.
Potted plants overwinter best indoors at temperatures around freezing point. It should not be too warm, otherwise there is a risk that the mulberry tree will be attacked by spider mites. If you don't have a suitable place in the house, place the bucket in the garage or in your garden shed (€24.90), possibly also on the south wall of your house.
A thick styrofoam or wooden plate serves as frost protection from below for potted plants. You can wrap the tub itself with bubble wrap, but the plant with garden fleece, because it needs air.
tips and tricks
Make sure that your mulberry tree gets enough liquid even in winter, otherwise it can dry out. Plant your mulberry tree in a tub for the first few years, then you can bring it indoors for the winter.
