Management of potted flowers and jasmine

1, potted flower environment and lighting: Jasmine likes hot, humid, ventilated and breathable environment, and needs sufficient lighting. Jasmine is afraid of cold. Potted jasmine in the south can be cultivated outdoors for wintering. In the north, warm work should be done in autumn and winter. Move indoors and put it in the south direction. Light is strong branches, leaves green, flowers and fragrance, lack of sunlight is sparse flowers and less fragrance.

2. Moisture: Jasmine is not drought-tolerant, but it is forbidden to accumulate water. In rainy seasons, it is necessary to dump accumulated water in the basin in time, otherwise the leaves are easy to yellow. Summer hot sunny days to water twice a day, morning and evening once, such as found that the leaves should be sprayed on the leaves, promote growth.

3. Soil: It is good to cultivate jasmine soil in fertile sandy and semi-sandy soil. Planting in slightly acidic soil with pH value of 6 to 6.5, the roots are dense and grow vigorously. If the soil is sticky and heavy, lack of matrix, low fertility, poor ventilation, less roots, short plants, slender stems and leaves, and fewer flowers.

4. Fertilization of potted flowers: The high temperature season in midsummer is the peak period for jasmine growth. Apply more organic fertilizer and phosphorus and potassium fertilizer, such as peanut cake powder, bone meal, calcium superphosphate and multi-element flower fertilizer, twice a month. Jasmine often appears luxuriant branches and leaves but does not bloom in summer growth period, the main reason is that too much nitrogen fertilizer is applied, resulting in excessive growth of branches and leaves. In such cases, fertilizer and water should be controlled, phosphorus and potassium fertilizer should be applied to promote bud breeding, and attention should be paid to moving jasmine to a place with sufficient sunshine and good ventilation.

5. Pruning: potted jasmine flowers grow very fast in summer, so they should be pruned in time. Potted jasmine pruning keeps the base 10 cm to 15 cm, promoting most of the sturdy new shoots. If the new shoots grow vigorously, they should be picked when growing 10 cm, and the second shoots should be promoted. Then there are more flowers and compact plant shapes. Flowers should be cut off in time after withering, reduce nutrient consumption, but also promote the growth of new shoots, so that branches dense, bud more, flowering more.

6. Prevention and control of pests and diseases: moth larvae, scale insects and red spiders are often harmful, especially from July to September. They often eat flower buds. They can be sprayed with all-purpose powder or fenvalerate and water 200 times. Spray once every half month. If no pests and diseases occur, they should also be sprayed. Prevention should be carried out first. Spray time should be 9 a.m. and 4 p.m. on sunny days. It is not suitable to spray at noon in the hot sun to prevent phytotoxicity.

7, potted flowers flowering maintenance: flowering period do not spray water on flowers, to prevent early flower fall and fragrance disappear, rain should be moved to the potted jasmine shelter.
