How does wisteria cultivate light and temperature?
Like warm, sunny, cold-resistant, slightly shade-tolerant.
water
Drought resistance, watering should follow the principle of not doing it, watering thoroughly. Potted soil has been kept moist or semi-moist, which is not conducive to its flowering.
Fertilize soil or land
Nitrogen fertilizer, superphosphate, etc. It can be applied before germination, and topdressing with decomposed human excrement and urine for 2~3 times during growth.
decrease
Pruning should be carried out during the pruning period, with the emphasis on pruning new branches 1/3 ~ 1/2, weak branches, dead branches and residual flowers. In addition, when the buds grow in spring, the dense buds are removed.
Wisteria has strong straight roots, so when transplanting, we should dig as many lateral roots as possible and bring the ground. Plant more in early spring. Before planting, you must set up a scaffolding, tie thick branches on the scaffolding and climb along it. Because wisteria has a long life and thick leaves, the scaffold materials must be strong and durable. When young trees are planted, the branches can't form flower buds, and peanut bud will appear later. If it doesn't bloom for several years, it's because the tree is too strong, with too many branches and leaves, and the tree is weak, so it is difficult to accumulate nutrients. The former uses partial root cutting and sparse branches and leaves, while the latter can blossom by adding fertilizer. Fertilizer should be properly applied with more potassium fertilizer. Topdressing is usually 2 ~ 3 times during the growth period. After flowering, 5 ~ 6 buds can be cut off from the middle branches and weak branches to promote the formation of flower buds.
Potted wisteria, in addition to selecting shorter species and varieties, should also strengthen pruning and coring, and control the plants not to be too large. If you are cultivating bonsai, you need to strengthen plastic pruning. If necessary, you can use old piles to plant pots and graft excellent varieties.
Cultivation management
When planting wisteria, you should choose a dry place with deep soil layer, fertile soil and good drainage. If it is too wet, the roots will rot easily. The planting time is generally from defoliation in autumn to germination in spring. The main root of wisteria is thick and long, with few lateral roots, which is not resistant to transplantation. Therefore, when transplanting, no matter whether the plants have soilless balls, they should be replanted, and organic fertilizer should be applied to the planting holes as base fertilizer. They should be watered after planting. For larger plants, a sturdy and durable shed should be built before planting, and thick branches should be tied to the frame after planting to make them climb along the frame. The daily management of wisteria is simple, and appropriate water and fertilizer management can be carried out according to the water and fertilizer status of the soil.
Pruning wisteria is an important work in management, and the pruning time should be in the dormant period. When pruning, the branches are evenly distributed by removing secrets and keeping sparse and manual traction. In order to make flowers flourish, we should also prune them reasonably according to their budding habits. Because wisteria has strong branching ability, flower buds are planted in the axils of annual branches, and the tops of growing branches are easy to dry up. Therefore, we should take back the new branches of that year, cut off 1/3- 1/2, and cut off the delicate branches and the base of dead branches.
