The wisteria is a real eye-catcher because of its long flower clusters. It's a shame when it doesn't bloom. However, these rules will help.
Wisteria is a fast-growing climbing plant that is very popular because of its grape-like flowers. Mainly because it is a real feast for the eyes in the spring when it starts to bloom. But again and again we hear from garden owners that their wisteria just doesn't want to bloom. This can have several causes. These three rules can help.
Rule 1 - The Right Location:
So that the wisteria can develop optimally, it needs the right location. It generally does best in a warm, sunny spot. If it is in partial shade, it will flower significantly less. A location on a south wall is ideal. Don't place it too close to a gutter, however, as it could climb up there and cause damage.
In addition, the wisteria needs a climbing aid because it grows very quickly. It is best to rely on stable, rod-like climbing aids. But wire ropes are also best. In any case, stay away from wooden scaffolding, because the wisteria will simply destroy it.
Rule 2 - The Right Floor:
The right floor is also important. This should best be:
- rich in humus
- lime-free
- sour to neutral
- moist but permeable to water
be. The soil must be low in lime, because if there is too much lime in the soil, the wisteria loses its leaves or turns them yellow.
Rule No. 3 - The right cut:
Average in the first two years:
The right cut is also important. After all, wisteria grows very quickly. In the first two years you only have to shorten the lower side shoots to two leaves. You must also remove all shoots that are close to the ground and wild shoots.
Average from Year 3:
From the third year you have to cut back the new shoots by half in late summer (August). Since the wisteria continues to grow until the frost, you will be on the cut shoots in the springcan find new growths again. You have to shorten these again to three to five eyes at the end of February. You should remove shoots that produce little or no green at all.
Always check the attachment to the climbing aid when cutting back. If you stick to all of the above, you will see an increase in flowering in the same year.
Tip:
