The life span of jasmine is generally ten to twenty years, and the flowering period is usually seven or eight years, especially three or five years. Jasmine likes warm and humid, and grows best in a well-ventilated semi-cloudy environment. The most suitable soil is slightly acidic sandy loam containing a lot of humus. Afraid of cold, drought, waterlogging and alkaline earth. When the temperature is lower than 3℃ in winter, branches and leaves are vulnerable to freezing injury, and will die if it lasts for a long time.

Potted jasmine: 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 rotten roots or fallen leaves. 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.

Cultivation techniques:

Soil quality:

Potted jasmine requires that the cultivated soil is rich in organic matter and has good water permeability and air permeability. 4 parts of general garden soil, 4 parts of compost, 2 parts of river sand or chaff ash, and a proper amount of fully decomposed dry cake powder, chicken and duck manure, etc. Sieve off powder and coarse particles, and cover the surface with coarse particles.

Upstream basin:

The most suitable time is April-May before new buds germinate every year. Choose a suitable flowerpot according to the size of the seedlings. When putting the pot, hold the seedlings in one hand and shovel the culture soil in the other. When the soil covers all the roots, lift the plants up slightly and vibrate the flowerpot several times to make the soil in close contact with the roots. Then compact the basin soil by hand, so that the soil surface is 2 cm away from the basin edge, which is reserved for watering.

Humidity:

After planting, water the roots, then put them in a slightly shady place for 7- 10 days to avoid direct sunlight, and then gradually see the light. The key to daily management is water. According to the characteristics of jasmine, such as being wet-loving, not drought-tolerant, afraid of stagnant water and breathable, we should master the time and amount of watering. It can bloom in June-July. At this time, the root system has resumed normal growth, and thin alum fertilizer water should be poured every 7- 10 days.
