4 tips for wintering silk trees
Winter silk tree in the house
If you cultivate your silk tree in a bucket, wintering in the house or in another frost-protected place is safest. Young trees and shrubs in particular are sensitive to freezing temperatures up to the age of three. Bring the silk tree into its winter quarters before the first night frosts begin.
Choose a bright place in the house where the temperatures are between 5 and 15 ° C. Unheated winter gardens as well as hallways and stairwells with windows are suitable winter locations. As soon as the night temperatures remain permanently above freezing in spring, you can bring the silk tree outside again.
Winter silk tree on the terrace
If your silk tree is at least four years old, it can spend the winter well protected on the terrace. Place the bucket on thick wood or, better still, on styrofoam to reduce the effects of frost on the ground. You wrap buckets, trunks and load-bearing branches with mats made of natural fibers such as coconut, jute or willow wood.
The cheaper bubble wrap is also suitable as frost protection, but leaves something to be desired in terms of aesthetics. The fiber mats are too heavy for the thinner branches and twigs of the silk tree. Use alternatives like linen cloth or the particularly light gauze fleece.
Winter silk tree in the garden
Adult silk trees in the garden survive the winter much better than their younger relatives in the tub. Temperatures down to -15 ° C are acceptable provided the roots are well protected. Spread dry leaves or bark mulch on the tree slice in late autumn and cover this layer with coniferous twigs.
The trunks and branches of adult silk trees can be released in a normal winter. However, if the weather forecast announces temperatures below -15 ° C, it is advisable, as with the tub plants, to use fiber mats, linen and fleece.
Water silk tree in winter
Silk trees also need water in winter, but significantly less than in the warmer seasons. So water continuously, but very sparingly. For silk trees in the garden and on the terrace, frost can completely prevent water absorption for a long time. Use frost-free days to make up for the shortage.
