What can that be? (Wisteria)

Why doesn't the wisteria bloom?

Before you worry about why your wisteria is not blooming, ask yourself whether it is old enough. A refined wisteria flowers for the first time around two to three years old. To do this, however, it has to be pruned regularly. Self grown from seed Plants often need a lot more time to bloom for the first time.

Further reasons for a failure to bloom are a wrong or missing pruning, Water and / or nutrient deficiency (especially in spring or just before flowering) and an unfavorable location. Because even if the wisteria grows quite well in the shade, it only blooms sparsely there. in the the shade In most cases, there is even no flowering at all.

Possible causes of failure to bloom:

• the wisteria is still too young (especially applies to self-grown plants)
• Over-fertilization, especially with nitrogen
• Insufficient supply of nutrients
• too shady Location
• Spring water shortage
• extreme drought during the flowering period (causes the flowers and / or buds to fall off)
• wrong or insufficient pruning

What can I do to make it bloom abundantly?

Before you can do anything in concrete terms, you must first find the cause of the lack of flowering. If the wisteria is too young, only patience and waiting will help. Was your wisteria in the spring or at the beginning of the Heyday too little poured, then you will probably have to wait until next year. In the future, water the plant regularly, but without causing waterlogging.

Even a wrong cut back cannot be undone. You don't have to worry too much though, the wisteria is even recovering from a radical cut. Cut according to good instructions in the winter and give it superphosphate in the spring. Then it will soon be in full bloom again. In the case of a wrong location, on the other hand, only one thing helps Transplanting.

The right pruning for a lush bloom

The wisteria only blooms on older short shoots. So you should definitely prune long whip shoots. Shorten this to 30 to 50 centimeters in August and to three to five eyes in winter. In between, young shoots can form there again, which you can simply break out.
