Potted Wisteria
The root system of Wisteria is developed. Although it likes sunshine, it is also resistant to shade. It is also resistant to cold and drought. It does not choose soil. It is easy to be planted in the open. However, it is not easy for Wisteria to maintain and manage as a potted plant, so there is a saying that "potted Wisteria does not bloom". If the following work can be done well, careful management, potted Wisteria will still flourish, bloom year after year.
1. Cut off the flowers in time to prevent the pod from growing. Wisteria blooms from the end of April to the beginning of May. After the flower has withered, it becomes a plump pod, up to 20cm long. A small potted Wisteria plant can produce more than 10 pods, which will consume a lot of nutrients and will be difficult to bloom in the next year. For this reason, the earlier the flowers are cut, the better.
2. Cut the elongated branches and vines in time to prevent them from climbing. Potted Wisteria must have nothing to climb around and form a small shrubby shape. But in the hot rainy season, even if there is nothing to climb around, sometimes they will stick out their branches and look around. If this phenomenon is found, the long vines should be cut off immediately to avoid nutrient consumption. Otherwise, once you climb around it, it will grow rapidly. Experience has proved that any potted Wisteria climbing around it will not bloom in the next year, or even sometimes for several years.
3. Do not overwinter at high temperature. If the potted Wisteria plants overwinter indoors, the room temperature is on the high side, and the wisteria does not get enough dormancy, it will consume the stored nutrients and affect the next year's flowering. Wisteria is more cold-resistant and can live through the winter outdoors. Even if the temperature drops below 0 ℃, it will not be frozen.
4. Control fertilization, potted Wisteria due to small pot soil, pot soil nutrients far from meeting the needs of its growth and flowering, not timely supplement of fertilizer, will affect flowering. However, without controlled fertilization, it is easy to make branches grow in vain and affect flowering. Generally, diluted cake fertilizer and water can be applied before flowering and long-term phosphate fertilizer can be applied after flowering to promote flower bud differentiation. There is no need to apply fertilizer in winter and summer.
