How Many Times Does Jasmine Bloom in a Year? A Detailed Guide to Its Blooming Cycle

Jasmine is a common aromatic ornamental flower for gardens and potted cultivation. It is an erect or climbing shrub in the genus Jasminum of the family Oleaceae, with emerald-green leaves, pure white flowers and a rich fragrance. Though it has no showy, crowd-stunning beauty, it combines the sweetness of the rose, the subtle fragrance of the plum blossom, the distant elegance of the orchid and the refined purity of the magnolia. Let us take a look below at how many times jasmine blooms in a year!

How many times does jasmine bloom in a year?

Jasmine blooms three times a year. Jasmine is extremely fond of fertilizer; with proper care it can bloom three times a year. The first blooming is in June, the second in August, and the third in September. If fertilizer is insufficient and nutrients are inadequate, it will not bloom again after the first flowering. The proper fertilization method is to apply liquid fertilizer rich in phosphorus frequently from June to September during the blooming period, preferably once every 2 to 3 days. Fertilizers can be well-rotted soybean cake and fish waste liquid fertilizer, or ammonium sulfate and superphosphate; generally, mixing too much chemical fertilizer will burn the jasmine plant to death. Spraying a 0.1% potassium dihydrogen phosphate aqueous solution on the leaves in the evening can also encourage more blooming.

When does jasmine bloom?

1. In early June, jasmine successively produces early flowers, but these flowers are generally small and few and should be removed in time; otherwise they consume too many nutrients, which will affect the quality and quantity of later blooms, delay the flowering period and affect the ornamental display. The method of removing flowers is to pick off the flower together with the leafy young shoot, prompting new shoots to grow again and the branches and leaves to become lush.

2. From late June to early July is the first peak blooming period. At this time, fertilizer and water management must be strengthened, applying light fertilizer frequently, once every 2 days, with fully rotted organic liquid fertilizer at a fertilizer-to-water ratio of 1:4. Watering should be sufficient, once every 2 days, preferably in the morning, while fertilizing is best done in the evening.

3. In early August the second round of flowers forms. At this time, fertilization should be slightly more concentrated than before, generally with equal parts fertilizer and water. To encourage jasmine to bloom better, a superphosphate solution can also be sprayed on the leaves. By late August, gradually reduce fertilization to once every 6 to 7 days; watering still needs to be relatively frequent, maintaining once every 2 days.

4. From early September to early October the third round of flowers forms. At this time, fertilization should be stopped, and the amount of watering should also be gradually reduced. As the weather has gradually turned cooler, which affects the formation of flower buds, this round of flowers is fewer in number. After mid-October, flowering ends, and it is only necessary to keep the potting soil slightly moist.

Why does jasmine fail to bloom?

1. Alkaline potting soil: Jasmine prefers soil rich in humus, loose and slightly acidic. If the potting soil is alkaline, jasmine will not bloom. Repot once a year to maintain the acidity of the potting soil, or during the growing season apply a 20% ferrous sulfate solution once every half month.

2. Insufficient light: Jasmine is a long-day, sun-loving flower that thrives on strong light and higher temperatures. There was once a saying that "jasmine cannot be sunburned to death." If it is too shaded and light is insufficient, the leaves will be small and thin, pale green in color, and growth and development will be poor, affecting the formation of flower buds.

3. Unsuitable temperature: Jasmine generally only forms buds at around 30°C. If the temperature is insufficient or exceeds 35°C, its growth will be affected. During vigorous growth, the optimum temperature is 25 to 30°C. In winter and spring, growth is slow or basically stops, and maintaining a temperature of 5 to 10°C is sufficient.

4. Improper watering: Jasmine needs a thorough watering each morning and evening, and when necessary, water should also be sprayed on the branches and leaves to keep the leaf surface fresh and enhance photosynthesis, thereby stimulating the formation of flower buds. If rainy days occur continuously, do not let the potted plant be exposed to rain, to avoid water accumulation and root rot.

5. Insufficient nutrients: Jasmine is a flower with a relatively strong demand for fertilizer. During bud formation and blooming, apply a phosphorus-based organic fertilizer liquid once every 3 days, such as soybean cake water, chicken or pigeon manure, superphosphate, bone meal, etc., or spray 0.2% potassium dihydrogen phosphate 1 to 2 times, and the flowers will be abundant, brightly colored and more fragrant.

6. Improper pruning: Jasmine should be pruned immediately after the flowers fade, because jasmine blooms at the ends of new branches, and only timely pruning will make new buds grow quickly. If leggy branches appear on the jasmine, they should also be cut short in time. After pruning, apply a heavy fertilization once, and after about a month it can bloom again.
