Not every plant can tolerate a radical cut, some have difficulty or even recover from it. However, you don't have to worry about wisteria, it is one of the plants that tolerates cutting very well, only its flowers suffer for some time.
When does a radical cut make sense for wisteria and what effect does it have?
A radical pruning of wisteria is useful if it has not been pruned for years or to rejuvenate an older plant. After cutting, the plant should be watered and fertilized well. The next flowering may be delayed and less lush.
When does a radical cut make sense for wisteria?
Usually you should cut back your wisteria once or twice a year. If you have neglected this for a few years, then a radical cut could make sense. This will bring the plant back into shape and bloom. Even an old wisteria can be rejuvenated by radical pruning and stimulated to bloom lushly and magnificently again.
When will my wisteria bloom again after a radical cut?
The time of the next flowering depends on various facts, including the time of cutting and the condition of the wisteria. The plant only flowers on the older shoots, so your wisteria needs a relatively long time. You shouldn't expect another flowering period until next year at the earliest, and it will probably be less lush than usual.
How do I care for my wisteria after a radical cut?
The wisteria is quite easy to care for, but you can pamper it a little after a radical pruning, because it needs a lot of strength for new growth. Water it regularly, but not too much, especially during a long dry period. Wisteria does not tolerate waterlogging, nor does it tolerate soil that is too dry.
On the other hand, you should be careful with fertilizer. Too much of it can harm your wisteria and cause chlorosis. In late summer you can use secateurs again (€14.00 on Amazon), provided your wisteria has already grown well by then. Shorten the new shoots to around 50 centimeters long, then to two to three flower buds in winter.
The most important thing about the radical cut in brief:
- Radical cut possible
- next flowering probably delayed
- contributes to the rejuvenation of the plant
- may be necessary if wisteria has been left unpruned for years
Tip
Give your wisteria plenty of time to recover after a radical cut. Since it only blooms on older shoots, at least the next flower will fail.
