In principle, the wisteria is considered hardy. However, that doesn't mean he can never freeze to death. Frost that is too severe over a long period of time is particularly harmful to wisteria in the bucket or to a very young plant, as well as the buds.

Especially younger wisteria should be protected in winter

Can I still save my frozen Wisteria?

As long as your wisteria's roots haven't frozen, you can certainly save the plant. However, you need a little patience until you can enjoy the usual lush flowering again. However, the roots rarely freeze, in the open ground they are quite well protected by the soil. In the planter, however, a long period of frost can be problematic.

How do I treat a frozen wisteria?

In the spring, when no more frost is to be expected, cut off all frozen shoots. You should also remove dried buds if they do not fall off on their own. Use sharp and clean tools to prevent the transmission of germs. At the interfaces, the wisteria quickly sprout again.

Care for your Wisteria as usual and avoid excessive fertilization. These promote the growth of the young shoots, but not the flowering of the buds that may still be present. In addition, an excess of nutrients can lead to yellow leaves and chlorosis.

How do I protect my wisteria from severe frost?

A young wisteria is not as tolerant of frost as an old one and can therefore use winter protection. Outdoors, you can pile a layer of leaves, brushwood or bark mulch over the roots.

Protect the above-ground parts of the plant by loosely wrapping the wisteria with bubble wrap or plant fleece. Make sure that the plant is still getting enough air and remove the protection in good time in spring.

The most important thing about wisteria and frost:

  • basically hardy
  • Buds and young shoots sensitive to frost
  • Cut off frozen plant parts
  • quite rapid re-growth
  • frozen flowers or flower buds = no flowering time

tips

Most of the time the whole plant is not frozen and the wisteria can still save it. Cut it back and give it some recovery time.
