Even if the wisteria looks exotic and reminds you of a summer holiday with its magnificent flowers, it is a hardy climbing plant. At least that applies to the older versions. A young wisteria, on the other hand, is still quite sensitive.

Older wisterias easily survive frost and snow

How do I overwinter potted and young plants?

It is best to overwinter a wisteria in a bucket or a very young wisteria in a cool and not too dark place. A cold greenhouse or an unheated conservatory is well suited for this. There may well be temperatures around freezing point, because the wisteria is basically hardy. In a mild area you can also overwinter it outside.

It is important that the roots of your wisteria do not freeze, otherwise the plant will die. Therefore, in a harsh area, the root ball should be protected from frost. You can achieve this, for example, by wrapping the planter from all sides (including the bottom!) with an old blanket, plant fleece or jute sacks. You can protect the parts of the plant above ground from frostbite with a layer of leaves, brushwood or bark mulch or with bubble wrap.

How do I care for my Wisteria in winter?

Your wisteria also needs water in winter, but only in small quantities. The soil should not dry out completely. The amount of water required varies depending on the prevailing temperature. Water only on frost-free days. In the winter quarters, your wisteria needs a little more water. However, you should avoid fertilizers.

How do I treat frost damage to my Wisteria?

If you discover a few frozen shoots on your wisteria in spring, then cut them generously down to the healthy wood. Within a short time, the plant will sprout again there. You can also easily remove frozen blossoms and buds. However, the wisteria will not bloom on these shoots in the coming season.

The most important winter tips for blue rain:

  • sensitive in the early years
  • good frost tolerance when old
  • Overwinter young and potted plants frost-free
  • young shoots and flower buds very sensitive to frost, protect from late frosts
  • Cut off frozen shoots, the plant usually recovers quite well

tips

If individual shoots freeze to death on your older wisteria, you can cut them off without worrying, the plant will recover very quickly.
