How do you grow and prune a climbing jasmine so it produces beautiful flowers?

Jasmine has a fresh, elegant fragrance, and its pure white, fragrant flowers have won the affection of many gardening enthusiasts. Besides being ornamental, jasmine can also be made into scented tea. So how do you grow jasmine? How do you prune it? What should you do if the leaves dry out and scorch? Below is an introduction to jasmine cultivation methods and points to note.

I. Introduction to jasmine

1. Overview

Jasmine, also known as Moli, is the collective name for evergreen shrubs or climbing plants of the genus Jasminum in the olive family (Oleaceae). Jasmine flowers are pure white with a rich fragrance and are among the most common fragrant potted flowering plants. The most famous type is the double-petaled jasmine, commonly known simply as jasmine. Fuzhou City in Fujian Province, China, is a famous jasmine-producing region.

2. Morphology

Jasmine generally grows 0.5-3 m tall, with slender branches. The simple leaves are opposite, elliptical or ovate, with entire margins, emerald green in color, thin in texture and glossy. The flowers are mostly white with a rich, fresh fragrance. The flowering period is from May to October, with the most abundant blooming in July and August, and they are fragrant.

3. Distribution

Jasmine prefers warm, humid environments with plenty of sunlight. It originated in India and Pakistan, and was introduced to China long ago, where it is now widely cultivated.

4. Uses

The flowers, leaves and roots of jasmine can be used medicinally, and can also be brewed as tea. The main ingredient of the famous jasmine tea is its petals. Jasmine flowers can treat externally-contracted fever, disharmony of the stomach, abdominal distension and diarrhea. Used as an essential oil in aromatherapy, it can help combat depression, kill bacteria and act as a sedative; it helps with anxiety and emotional instability, and is good for the skin and scalp.

II. How do you grow jasmine?

Jasmine likes warmth and humidity, and grows best in a well-ventilated, semi-shaded environment. The most suitable soil is a slightly acidic sandy soil containing plenty of humus. For details on how to grow it, let's look at the cultivation methods and points to note below:

1. Soil: The soil for cultivating jasmine should be fertile sandy or semi-sandy soil; it grows best in slightly acidic loam rich in humus.

2. Temperature: Jasmine likes high temperatures. It usually begins to sprout at around 20°C, forms buds above 25°C, and forms flower buds at around 28°C-33°C. Its optimum growing temperature is 22°C-35°C. If the temperature is too high, the plant enters a semi-dormant state, flowering less and unevenly. If the temperature is too low, the plant grows slowly and is not tolerant of low temperatures; below 5°C for a long time, some branches will freeze to death. Therefore, in southern regions it can be grown outdoors through the winter, while in northern regions, in autumn and winter you need to keep it warm by moving it indoors and placing it in a south-facing spot.

3. Light: Jasmine likes humid, well-ventilated environments and needs ample light. Unsuitable environmental light will cause the plant to grow leggy, with leaves turning pale green and thin, and branches becoming slender, with longer, tender internodes, fewer flower buds, less flowering, and smaller, less fragrant flowers.

4. Water: Jasmine likes humid environments, so it has relatively high water requirements, but jasmine is afraid of waterlogging. If the potting soil remains wet for a long time, the roots will rot due to lack of oxygen in the soil, the leaves will gradually turn yellow and fall off, and the whole plant may even die.

Watering should be determined according to season and temperature. In spring, from April to May, you can water once every 2-3 days, preferably around midday. In June, you can water slightly more, once a day. In summer, July to August is the high-temperature period and also jasmine's peak flowering period, so it needs watering once each in the morning and evening, while also spraying water on the leaves 1-2 times a day and sprinkling water around the flowerpot to increase air humidity. In autumn, gradually reduce the amount of watering; from September to October, water once every 1-2 days. In winter, watering should be strictly controlled, keeping the potting soil only slightly moist, generally watering once every 5-7 days.

5. Fertilizing: Jasmine's flowering period is relatively long, so the potting soil must have sufficient fertility. When fertilizing, follow the principle of “light fertilizer, applied frequently”; do not apply too much at once. Especially in winter and during high-temperature seasons, avoid fertilizing. Fertilizing after entering the growing period gives better results. The best time to fertilize is in the evening, and the potting soil should be loosened before applying.

6. Repotting: Jasmine that has been grown for more than 2 years needs repotting. By then the fertility in the potting soil has declined, and the roots have become tangled and crowded, so it is necessary to change to a larger pot and refill it with loose soil.

7. Pests and diseases: Jasmine is susceptible to damage from red spider mites, leaf spot disease, scale insects and other pests and diseases, with July to September being the most severe period, so timely prevention and control are needed.

III. How do you prune jasmine?

Jasmine is generally pruned in early to mid-March each year. When pruning, branches can generally be left 20 cm long, and the rest should be cut off. Old branches should be cut off from the base, keeping 10 cm to 15 cm from the base, to encourage them to sprout robust new branches. At the same time, remove overly dense branches, leggy branches and weak branches, and pick off old leaves. If new shoots are growing very vigorously, pinch them back when they reach 10 cm to encourage a second flush of shoots, resulting in more flowers. After flowers fade, the flowering branches should be cut off promptly to reduce nutrient consumption.

IV. What should you do if jasmine leaves dry out and scorch?

Because jasmine leaves are relatively thin, they are more sensitive than other flowers. When growing jasmine in pots, leaf drying and scorching is prone to occur. You must treat the cause accordingly, otherwise it can lead to the death of the plant. Specifically, the following points cause leaves to dry out and scorch:

1. Improper fertilizing: If the leaf tips scorch, it may be caused by improper fertilizing, such as applying fertilizer that is too concentrated, too much, or using unrotted fertilizer, causing “root burn”.

Solution: In mild cases, water more to dilute the fertilizer. In severe cases, replace the soil and replant, place the pot in a shaded spot, and resume normal care after new shoots appear.

2. Improper watering: Jasmine likes humid environments. Excessive drought and lack of water, or too much water causing root rot, can both lead to leaves drying out and scorching.

Solution: For drought and lack of water, appropriately increase the frequency of watering; for too much water causing root rot, control the frequency of watering.

3. Unsuitable soil pH: Jasmine likes acidic soil. If the pH is unsuitable, it can lead to leaves drying out and scorching.

Solution: Change to acidic soil with a pH of 6 to 6.5.

In addition, another possible reason for jasmine leaves drying out and scorching is that there are too many flowering branches that have not been pruned, affecting the plant's nutrient absorption.

V. The flower language of jasmine

Jasmine is pure and rich, and its flower language is loyalty, respect, purity, chastity and simplicity. Many countries have chosen jasmine as their national flower, and it also represents the flower of love and the flower of friendship.

Conclusion: The cultivation methods for jasmine are introduced here. In fact, jasmine is still a very easy flowering plant to grow. As long as you normally pay attention to jasmine's temperature, light, fertilizer and water, you can generally grow it well.
