Jasmine is white and fragrant. It blooms continuously from summer to autumn. It can be roughly divided into four flowering periods, of which July to August is the full flowering period. The flowers are large, fragrant and abundant. The key to make jasmine flower fragrant is to strengthen the management of flowering period, control water, fertilizer and light, prune properly and control diseases and insect pests. Let's learn about Jasmine flowering time, planting method and how to maintain it with Xiaobian!
What month does jasmine flower
1. Fertilize more flowers
Jasmine is fond of large amount of water and fertilizer in summer. Liquid fertilizer or organic fertilizer (such as peanut cake powder, bone powder, calcium superphosphate and multi-element flower fertilizer) rich in nitrogen, phosphorus and potassium can be applied twice every two days. If it can be used alternately with alum fertilizer water, the effect will be better. This can not only make the plant nutrient balance, green and thick leaves, big and fragrant flowers, but also effectively prevent the occurrence of plant etiolation.
Jasmine often has 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 branches and leaves. In this case, it is necessary to control fertilizer and water, increase phosphorus and potassium fertilizer, promote the breeding of flower buds, and pay attention to move jasmine to a place with sufficient sunshine and good ventilation.
2. Water frequently
Jasmine likes humid environment, so watering is more important in its flowering period. Due to the high temperature in summer and the large transpiration of the plant, sufficient water should be given. Water should be poured once in the morning and once in the evening, and clean water should be sprayed once in the morning and once in the afternoon to enhance the air humidity. However, it should be noted that less or no water should be given on cloudy and rainy days, and rain should be avoided on rainy days to prevent ponding in the basin.
3. Suitable pH of soil
The growth of Jasminum Jasminum L. was promoted by pH 6.0 or pH 6.0.
4. Illumination
Jasmine likes light and needs enough light. If the light is not enough, the branches will be slender and the leaves will turn yellow. If the light is too strong in midsummer, it should be shaded properly, otherwise the leaves will be easily burned by the sun. Jasmine can be placed in half shade, only to accept the light before 9 am and after 5 pm.
5. Temperature
Jasmine likes hot, humid, ventilated environment, and is afraid of cold. Potted Jasmine in South China can be cultivated outdoors for winter. In North China, it is necessary to keep warm in autumn and winter, and move it indoors to the south. Strong light makes the branches strong, the leaves dark green, the flowers more fragrant, the lack of sunlight makes the flowers less fragrant.
6. Pruning
Jasmine grows fast in midsummer, so it should be pruned in time. If the base of potted jasmine is kept at 10-15cm, it can promote most of the strong new shoots. If the new shoots grow vigorously, it should be pinched when they grow 10cm and promote the secondary shoots, then they will blossom more and the plant shape will be compact. The flowering branches should be cut short in time to reduce nutrient consumption. It can also promote the growth of new shoots and more lateral branches, so that the branches are dense, the buds are more, the buds are more pregnant, and the flowering is more natural.
7. Pest control
Jasmine will be damaged by scale insects, red spiders and aphids in summer. If there is a small amount of jasmine, it can be caught manually. If there is a large amount of jasmine, it can be sprayed with 1000 times 40% Omethoate EC to kill scale insects and aphids, and sprayed with 1000 times 20% dicofol EC to kill red spiders. Jasmine is vulnerable to leaf spot disease in summer. It can be controlled by spraying 800 times 75% chlorothalonil when it occurs.
8. Flowering maintenance
Don't spray water on flowers during flowering period to prevent early flower falling and fragrance disappearing. When it rains, move potted jasmine to shelter from rain.
Early June is the first flowering period of jasmine. Jasmine will bloom early in succession, but it is usually small and few, so it should be picked in time. Otherwise, it will consume too much nutrients, affect the quality and quantity of late flowering, and delay flowering. The method of picking flowers is to pick the flowers, take the leaves and tender branches, as well as the disease of withered yellow and weak yellow.
The second flowering period of jasmine is from late June to early July. At this time, it is necessary to strengthen the management of fertilizer and water, master the principle of "thin fertilizer and frequent application", apply fertilizer once every two days, apply fully decomposed organic liquid fertilizer, and the ratio of fertilizer and water is 1:4. Do not apply unripe 'raw fertilizer', which can not be absorbed by root system. It will cause water backflow of flowers and cause 'fertilizer damage'.
Early August, the third flowering period. During this period of time, fertilization should be slightly thicker than before. Generally, half of fertilizer and half of water are suitable. In order to make jasmine Blossom better, 2% superphosphate solution can be sprayed on the leaves. By the end of August, the fertilization should be reduced gradually, once every 7 days, and more watering should be done, once every 2 days.
From the first ten days of September to the first ten days of October, the fourth stage of flower formation. Fertilization should be stopped and the amount of watering should be reduced gradually. Because the weather has turned cold and the light intensity is weakening, which affects the formation of flower buds, the number of these flowers is small. As the saying goes: 'Zhulan is immortal in shade, jasmine is immortal in sun'. Potted jasmine, only in a sunny environment, can make the leaves green, the branches strong, the buds more, the flowers more fragrant. After the middle of October, the flowering is over, and the pot soil should be kept slightly wet.
