1. Plant potted jasmine and water it every morning and evening in summer. If the air is dry, it needs to be supplemented with water spray; During the winter dormancy period, it is necessary to control the amount of watering. If the pot soil is too wet, it will cause a large number of rotten roots or jasmine flowers to multiply by cutting, layering or dividing plants. The cuttage propagation of Jasmine was carried out from April to June, 65438+1October. Select the mature branches of 1, cut them into cuttings with more than two nodes, remove the lower leaves, insert them on a semi-sandy bed, cover them with plastic film, keep the air humidity high, and take root after about 40-60 days. Jasmine is propagated by layering. Select long branches, cut them lightly at the lower part of the node, and bury them in a small basin filled with sand and mud, and keep them moist frequently. After 20-30 days, they begin to take root. After two months, they can be cut from the mother plant to become seedlings and planted separately. Apply pancake fertilizer once a week during the growing period. After changing pots in spring, we should always pick our hearts and shape them. Cut it again after flowering to help sprout new branches, so that plants can be neat and robust and bloom vigorously.

2. Light and temperature enter the greenhouse before the first frost every year, and the wintering room temperature is 5- 10℃, which will be frozen below 5℃ and easy to die below 0℃. The optimum growth temperature is 20 -25℃. After Grain Rain in spring, we should move out of the greenhouse. Before going out, you should exercise gradually in a sunny place indoors and go out slowly. After leaving the house, it should be placed in the leeward and sunny place, and then let go of management after adapting to the outdoor environment.

3. The principle of watering and fertilizing jasmine is to "water thoroughly if you don't do it". Pour it after filling 1 time. According to the weather conditions in spring and autumn, water is poured 1 every 2-3 days, and water can be sprayed every day to keep the air moist. Spray water 1 time every morning in summer, and water 1 time after 4 pm. Reduce the amount of watering in the greenhouse in winter, otherwise the roots will rot easily. Molly likes fertilizer. /kloc-after 0/month, you can start pouring alum fertilizer and water. With the increase of weather temperature and plant growth potential, the concentration of fertilizer and water can be gradually increased, and dry fertilizer can be applied in rainy season. Phosphorus and potassium fertilizer can be applied topdressing before and during flowering to promote flower reproduction and fragrance. Top dressing after each flowering 1 time. Stop topdressing at full flowering stage. Stop fertilizing after entering the house in winter.

4. Plastic pruning Jasmine can be pruned in March. First, dense branches, dead branches, weak branches, cross branches, etc. Prune, and then cut the remaining branches short, and the length of the remaining branches is 15 cm, which promotes the growth of new branches and is beneficial to flowering. If you want jasmine flowers to bloom well and big, you should erase some buds in 1 crops in spring, or pick branches-some of them are tender. Every time a flower is finished, it is necessary to remove the residual flowers in time to concentrate nutrients for the next flower.
