How to feed and fertilize lilacs in Thailand

Jasmine began to bloom in early summer. If properly managed, it can blossom in three phases.

In early June, jasmine blossoms one after another, but these flowers are generally very small and few, so we should pick them in time, otherwise it will consume too much nutrients, affect the quality and quantity of its later flowering, delay the flowering period and affect the appreciation. The method of picking flowers is to pick the tender branches with leaves, so as to promote the new branches to germinate again and flourish. At this time, light fat water is applied twice a week to keep the basin soil moist.

Late June to early July is the first stage of flowering. At this time, it is necessary to strengthen the management of fertilizer and water, apply thin fertilizer frequently, apply/kloc-0 every two days, and apply fully decomposed organic liquid fertilizer, with the ratio of fertilizer to water of 1: 4. Watering should be sufficient, generally 2 days 1 time. Usually watering should be done in the morning and fertilizing should be done at night. This situation will last until the end of July. Due to abundant fertilizer and water, bloom has a great harvest.

In early August, the second stage of flowering, when fertilization is slightly thicker than before, it is generally appropriate to divide fertilizer and water equally. In order to promote jasmine to bloom better, calcium superphosphate solution can also be sprayed on the leaves. By the end of August, fertilization was gradually reduced, and 1 time was applied for 6 to 7 days, but more water was needed, and 1 time was maintained for 2 days.

From early September to early 10, the third stage flower is formed. At this time, fertilization should be stopped and the amount of watering should be gradually reduced. Because the weather has gradually turned cold, which will affect the formation of flower buds, the number of these flowers is small, and the flowering will end after the middle of 10, and the pot soil can be kept slightly wet.

How to make jasmine blossom more?

1. Environment and lighting: Jasmine likes a hot, humid, ventilated environment and needs sufficient lighting. Molly is afraid of cold. Potted jasmine in the south can be cultivated outdoors for the winter. In the north, keep warm in autumn and winter, move indoors and put it in the south direction. Strong sunlight makes branches strong, leaves dark green and flowers more fragrant, while insufficient sunlight makes flowers less fragrant.

Second, moisture: jasmine is not drought-tolerant, but it is necessary to avoid water accumulation. Pour out the water in the basin in time during the rainy season, otherwise the leaves will turn yellow easily. Water the leaves twice a day on a hot sunny day in summer, once in the morning and once in the evening. If you find the leaves drooping, spray water on them to promote growth.

3. Soil: It is best to plant jasmine in fertile sandy and semi-sandy soil. When planted in slightly acidic soil with pH value of 6-6.5, the root system will be dense and grow vigorously. If the soil is sticky, lacks matrix, has low fertility and poor ventilation, there will be fewer roots, short plants, slender stems and leaves, and few and small flowers.

Fertilization: The high temperature season in midsummer is the peak of 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. In summer, jasmine is often leafy but does not bloom. The main reason is that too much nitrogen fertilizer is applied, resulting in too many branches and leaves. In this case, it is necessary to control fertilizer and water, apply more phosphorus and potassium fertilizers to promote germination, and at the same time pay attention to moving jasmine to a sunny and well-ventilated place.

5. Pruning: Jasmine grows very fast in summer, so it should be pruned in time. The base of potted jasmine is trimmed to 10 cm to 15 cm, which will promote most robust new shoots. For example, new shoots grow vigorously, and when they grow to 10 cm, they should be pruned to promote the growth of secondary branches, which will lead to more flowers and compact plant types. After the flowers wither, the branches should be cut off in time to reduce nutrient consumption, which is also conducive to promoting the growth of new shoots, making the branches dense, with more buds and more flowers.

6. Pest control: Jasmine often suffers from moth larvae, scale insects and red spiders, which are the most serious from July to September and often eat flower buds. It can be sprayed with universal powder or pyrethroid and 200 times of water once every half month, even if there are no pests and diseases, so as to prevent problems before they happen. The suitable spraying time is 9: 00 am and 4: 00 pm on sunny days, and it is not suitable to spray in the hot sun at noon to prevent phytotoxicity.

Seven, flowering maintenance: don't spray water on the flowers during flowering to prevent premature flowering and fragrance loss. When it rains, the potted jasmine should be moved to a shelter.

Conservation of potted jasmine in northern China

The culture soil is made of jasmine-like, fertile and loose, slightly acidic soil with good drainage. 4 parts of general pastoral soil, 4 parts of compost soil, 2 parts of river sand or chaff ash, and an appropriate amount of fully decomposed cake powder, chicken and duck manure, etc. Be used. You can also create your own cultural soil. Garden soil and animal and plant raw materials (such as vegetable leaves, branches and leaves, melon and fruit skins, feathers, fish viscera, etc.). ) according to the preparation of a layer of soil and a layer of animal and plant raw materials, put them into plastic bags or flowerpots and compact them with rice washing water. In this way, after a winter, the soil suitable for jasmine planting can be made. In order to keep the soil slightly acidic, 0.2% ferrous sulfate water can be poured every 10 day.

After two to three years of growth, the roots of jasmine in potted soil are intertwined, and the rational performance of cultivated soil becomes worse. At this time, if the pots are not changed, the growth of jasmine will be seriously affected. Better change the jar before Molly leaves the room. Generally, when changing pots, the roots are not trimmed, and new nutrient soil is replaced. Some bone meal and horseshoe blocks at the bottom of pots are used as base fertilizer, and then the pots are watered.

Proper watering should be based on the characteristics of jasmine, like being wet and afraid of stagnant water, and like breathing freely. From April to May in spring, jasmine is sprouting and spreading its leaves, with low temperature and little water consumption. It can be watered once every two to three days, and it must be watered thoroughly at noon. May-June is the spring flower period, and watering is slightly more than the previous period. June to August is the dog days, with the highest temperature, and it is also the blooming period of jasmine. The sunshine is strong and the water demand is high, so it can be watered once in the morning and evening. When the weather is dry, you should also spray water on the ground around the leaves and pots. From September to June 10, you can water it every 0-2 days from June 10, and the amount of water must be strictly controlled in winter, otherwise the humidity of the basin soil is too high and the temperature is too low, which is not conducive to jasmine overwintering. As far as the principle of watering during the growing period is concerned, it means that if you don't do it, the soil in the basin will be watered thoroughly.
