4 tips for hibernating silk trees
Hibernate silk tree in the house
If you cultivate your silk tree in the bucket, the hibernation in the house or in another frost-protected place is the safest. Young trees and shrubs in particular are sensitive to freezing temperatures until the age of three. Bring the silk tree to its winter quarters before the first night frosts begin.
Choose a bright spot in the house where temperatures are between 5 and 15° C. Unheated conservatories and corridors and staircases with windows are suitable as winter locations. As soon as the nighttime temperatures remain permanently above freezing in spring, you can bring the silk tree back outside.
Hibernate silk tree on the terrace
If your silk tree is at least four years old, it can hibernate well protected on the terrace. Place the bucket on thick wood, or even better on polystyrene, to soften the effect of the ground frost. Buckets, logs and viable branches are wrapped in natural fiber mats such as coconut, jute or willow.
The cheaper bubble wrap is also well suited as antifreeze, but leaves to be desired in terms of aesthetics. For the thinner branches and branches of the silk tree, the fiber mats are too heavy. Use alternatives such as linen cloth or the particularly light gauze fleece.
Hibernate silk tree in the garden
Mature silk trees in the garden survive the winter much better than their younger relatives in the bucket. Temperatures down to -15° C are acceptable provided the roots are well protected. Distribute dry leaves or bark mulch on the tree disc in late autumn and cover this layer with softwood rice.
The trunks and branches of mature silk trees can release you in a normal winter. However, if the weather forecast announces temperatures below -15° C, the handle to fiber mats, linen and fleece is advisable, as with the tub plants.
Pour silk tree in winter
Silk trees need water even in winter, but much less than during the warmer seasons. So pour 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 compensate for the shortage.
