In principle, wisteria is considered hardy. However, that doesn't mean he can never freeze to death. Excessive frost over a long period of time is particularly damaging to wisteria in a pot or a very young plant as well as the buds.
What to do if wisteria freezes?
You can save a frozen wisteria by cutting off all frozen shoots and dried buds in the spring. The plant then sprouts again quickly, but needs some time to regain its lush flowers.
Can I still save my frozen wisteria?
As long as the roots of your wisteria are not frozen, you can definitely save the plant. However, you need a little patience until you can enjoy the usual lush blooms again. However, the roots rarely freeze; in the open field 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 spring, when frost is no longer 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. The wisteria quickly sprouts again at the interfaces.
Care for your wisteria as usual and avoid excessive fertilizer. These promote the growth of the young shoots, but not the flowering of any 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 frost-tolerant as an old one and can therefore really use winter protection. In the open field 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 still gets 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
- very rapid new growth
- frozen flowers or flower buds=no flowering period
Tip
Most of the time the whole plant is not frozen and the wisteria can still be saved. Cut it back and give it some recovery time.
