Potted jasmine and its management methods

Jasmine pot culture requires that the cultivated soil is rich in organic matter, and has good water permeability and aeration properties. Generally, 4 parts of pastoral soil, 4 parts of compost, 2 parts of river sand or grain bran ash, plus an appropriate amount of fully rotten dried cake, chicken and duck manure, and sift out the powder and coarse grains, cover the bottom with coarse grains. The most suitable time for potting is before the new shoots germinate from April to May every year. Choose the right flowerpot according to the size of the seedling. Hold the seedling with one hand and fill the culture soil with the other. After the soil covers all the roots, lift the plant slightly upward and vibrate the basin a few times to make the soil in close contact with the root system.

Then compact the basin soil by hand, so that the soil surface is 2 centimeters away from the edge of the basin, leaving it for watering. After planting, pour root water, and then put it in a slightly shaded 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 like wetting, drought tolerance, fear of stagnant water and air permeability, we should master watering time and amount of water. It can blossom from June to July. At this time, the root system has returned to normal growth, and thin alum fertilizer water should be irrigated every 7-10 days. In the future, it can be managed according to adult jasmine, and the pot will no longer be changed in that year.

Potted jasmine flowers should generally be changed once a year. When changing the basin, part of the old soil and residual roots around the jasmine root system were removed and replaced with a new culture soil to improve the soil aggregate structure and nutrients, which was beneficial to the growth of jasmine. When you change the basin, water it thoroughly as if it were on the basin, so that the root soil can be connected closely and the growth can be restored. Before changing the basin, the jasmine should be trimmed once, leaving only about 10 cm for the branches born last year, and cut off the diseased and withered branches and the over-dense and thin branches. During the growing period, the old leaves that are too dense are often removed, which can promote the germination of axillary buds and the emergence of new branches and long buds.

From April to May in spring, jasmine is drawing branches and long leaves, and the water consumption is small, so it can be watered once every 2-3 days, and it must be watered thoroughly before and after noon; May-June is the spring flowering period of jasmine, and watering can be slightly more; the climate of high temperature is from June to August in midsummer, which coincides with the flowering period of rapid growth of jasmine and accelerated evaporation of leaves, strong sunshine and more water, which can be watered once in the morning and evening. In case of drought, water should also be used to spray leaves and the ground around the basin. Because jasmine is not resistant to drought and waterlogging, the stagnant water in the basin should be removed in time on rainy days in summer, and the temperature in autumn can be reduced to watering once every 1-2 days; in winter, the amount of watering should be strictly controlled, such as excessive humidity of basin soil, which is disadvantageous to overwintering.

Jasmine likes fertilizer, especially the long flowering period, which needs more fertilizer. It also likes acidic soil and can be watered with 1:10 alum once a week. After the first flowering, it is appropriate to use bean cake as forced fertilizer, apply it in topsoil, apply bone powder and phosphate fertilizer when flowering, and conditionally pour rotten human feces and urine, so as to make jasmine fragrance rich. In the high temperature of flowers, should be fertilized every 4 days, might as well be fat and water, generally watering in the morning, fertilizing in the evening, and hydrolyzing the next day, which is conducive to the absorption of jasmine roots. Fertilizing should not be too thick, otherwise it is easy to cause rotten roots. Before watering, use a small shovel to slightly loosen the basin soil and then irrigate it. Do not fertilize the basin soil when it is too dry or too wet. Fertilization is the best when it seems to be dry and non-dry.

In order to make the plant shape of potted jasmine plump and beautiful, the residual branches should be cut off immediately after blooming, so as to promote the germination of new techniques at the base and control the height of the plant. Stop fertilizing in the first ten days of September to improve the maturity of branches and be beneficial to overwintering. Jasmine is afraid of the cold. When the temperature drops to 6-7 ℃, it should be moved into the room. At the same time, attention should be paid to opening the window for ventilation so as not to cause the leaves to turn yellow and fall off. At this time, the temperature is often unstable, when the weather is warm, you should still move outside and be ventilated to see the light. Jasmine moved indoors for the winter, should be placed in a sunny room, the room temperature should be more than 5 ℃. Water is watered every 7 days or so to make the basin soil slightly wet. In this way, the branches and leaves can be kept green in winter without losing its ornamental effect.
