Prune twice
Wisteria only grows really well if you give it a regular pruning. This pruning ensures that extra flowers appear in the spring. It also helps to control the plant so that it does not grow in all directions. This can sometimes happen with the wisteria! You should therefore not only prune it in the winter period, but also in the summer.
That’s how you prune it!
First winter – January/February
After planting the wisteria, cut the main branch back to about 75 – 90 cm and remove all side shoots. In winter, make sure that you do not prune the plant when it freezes. This can cause damage to the plant.
First Summer – July/August
Now attach two strong side branches. Shorten the side shoots to about 3/4 buds. This way you encourage the plant to continue to grow in a beautiful way.
The following January/February
During this period, cut back the previously shortened shoots again, to about a finger’s length. You will see that 2 or 3 buds remain and then tie the lowest branches horizontally with a string or a special clip. You can already see which buds will come out in spring, because these flower buds are much rounder than the pointed leaf buds!
Bind the main branch and the main branches as well. Frame branches are the thicker branches that are attached to the main branch. In this way the plant becomes even higher and wider. Would you rather not? Then you should leave this alone. If your plant is already big enough, you can simply shorten the main branch and the main branches. Then cut all young shoots that have developed on the main branches back to about 5 to 6 eyes. Do you find counting too much of a hassle? Then you could also hold a hand length. This is not very precise.
The following July/August
Then in the summer always cut away the long shoots and cut long branches to 2 to 3 buds. This ensures that the wisteria retains a beautiful shape.
If you don’t keep track of the wisteria properly, it can even prevent it will not bloom in the spring! So take your time and prune it twice a year.
