Wisteria, which is not tolerant of fertilizer and applies less fertilizer, has strong adaptability to the environment, and the taproot can absorb nutrients from the soil without excessive fertilization. Basically, applying compound fertilizer 2~3 times a year can meet its growth needs. A small amount of nitrogen fertilizer and superphosphate can be applied before the plants germinate to promote the growth of branches and buds. Top dressing 2~3 times during the growth period, using decomposed human and animal feces.
The soil layer should be deep. The main roots of wisteria are very long, leaving enough space for roots to grow. When planting, choose areas with deep soil layers. Wisteria has lower requirements for soil quality, but fertile soil will grow better.
Like the sun, wisteria is a large vine, mostly wild outdoors. You don't need extra sunshine, just normal sunshine. It grows more vigorously when there is plenty of sunshine in summer. Of course, if you enjoy the sunshine, you can also resist the cold. As long as the potted plants are placed by the window, the room temperature is above zero, and there is sunshine during the day, you can safely spend the winter.
Overgrowth, timely pruning wisteria grows rapidly under suitable conditions, even the improved varieties in potted plants grow faster than other plants. In order to ensure the beauty of trees, we should not only reduce watering and fertilization, but also know how to prune and core. Pruning is usually carried out during the annual dormancy period, with dense going and sparse staying. Generally speaking, coring is carried out every year when new buds grow. When the new shoots grow to 15 cm, cut off the buds at the front of the new shoots. Read the article to learn more about wisteria techniques. Main points of shaping and pruning wisteria. )
