As wisteria is planted, so is wisteria.

Commonly used cutting, dividing plants and sowing propagation.

1. Cuttings are easy to survive, and hard cuttings in spring germinate late and take a long time. Before sprouting in spring, select robust branches of 1 ~ 2 years old, cut them into cuttings of 65,438+0.5 cm ~ 20 cm, and insert them into 2/3 of the soil. It is better to use loose and well-drained sandy soil as substrate, and pay attention to moisturizing after insertion, and the survival rate can reach above 90%. Softwood cuttings can also be carried out in summer, but attention should be paid to shading and moisturizing. Wisteria can also be cut with old stems. In early spring, select branches that are more than 3 years old, cut them into cuttings of 20 cm to 30 cm, and bury them in the soil for 2/3. Pay attention to moisturizing. This method is often used to cultivate bonsai materials by stumps.

2. Tillers at the roots of plants are planted separately before ramets germinate in spring.

3. Before sowing, dry the seeds, sow them in early spring and emerge in April. Keep the soil moist and fertilize properly, and some seedlings can bloom in the same year.

cultivation techniques

1. Planting should choose sunny environment, moist fertile loam with good drainage, and transplanting in spring is the best.

2. During the whole growing period, watering should always keep the soil moist.

3. Fertilization and adequate fertilizer are the keys to more buds and better flowering of Lagerstroemia indica. In early spring, basal fertilizer should be applied again, which is the guarantee of flowering, and topdressing should be carried out in May-June to promote the formation of flower buds.

4. Plastic repair technology Lagerstroemia indica is resistant to pruning and can be cut into round-headed trees that are taller and lower than trees. It is very effective to control the height and shape of the crown by re-cutting or even sawing, and it can bloom in the year of germination. Cut the inflorescence in time after flowering to preserve nutrition, which is conducive to the next year's flowering.

5. The flowering period of Lagerstroemia indica is the last flowering period in late September. In order to make it bloom during the National Day, we can cut short and full-flowered Zizang new shoots in early August, cut off all the flower branches and 65,438+0/3 of the new shoots, and strengthen the management of fertilization. After about 65,438+0 months, the new shoots will form flower buds again and can bloom again.
