What to Do When Jasmine Won't Bloom? Cause Analysis and Treatment Methods
Jasmine keeps its leaves emerald green all year round. From early summer to late autumn, its fragrance lasts for months without pause, its flowers are pure and white, and its charm is lovely and moving. However, some jasmine plants have luxuriant branches and leaves but few flowers; some even fail to bloom at all. Here is a diagnosis and treatment of the main causes, for reference.
Alkaline potting soil: Jasmine prefers soil rich in humus, loose and slightly acidic. The potting soil can be made from pond mud, garden soil and rice-hull ash in a 3:4:3 ratio (mountain soil sold on the market will also do). Methods to prevent and correct alkaline potting soil: first, repot once a year to keep the soil acidic; second, during the growing season, water with a 20% ferrous sulfate solution once every half month to turn the leaves green again.
Insufficient light: Jasmine is a long-day, sun-loving flower. It likes strong light and higher temperatures. There was once a saying that "jasmine cannot be sunburned to death." Therefore, the potted plant should be placed in a courtyard or on a balcony with ample light, so that it gets plenty of sunshine, which helps the flower buds sprout. If it is too shaded and the 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.
Unsuitable temperature: Jasmine generally only forms buds at around 30°C. If the temperature is too low or exceeds 35°C, its growth will be affected.
Improper watering: Both excessive dryness and excessive moisture will make jasmine leaves turn yellow. When too wet, the leaf tips turn yellow and the edges take on a rusty water-stained color; when too dry, the leaves turn yellow and withered, with no rust spots on the surface. Because summer light is intense, the air is dry, and metabolism is fast, the plant needs watering once each morning and evening, but it must be watered thoroughly. When necessary, water should also be sprayed on the branches and leaves to keep the leaf surface clear and enhance photosynthesis, thereby stimulating the formation of flower buds. If there are consecutive rainy days, do not let the potted plant be exposed to the rain, so as to avoid water accumulation and root rot.
Insufficient nutrients: Jasmine is a flower with a fairly strong need for fertilizer. In summer, when it enters full bloom, apply a topdressing of thoroughly decomposed dilute liquid fertilizer once every 3 to 5 days; during the bud-setting and blooming period, apply an organic fertilizer solution mainly based on phosphorus once every 3 days, such as cake fertilizer 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 and brightly colored, with an even richer fragrance.
Timely pruning: After the flowers fade, pruning should be carried out at once, because jasmine blooms at the ends of new branches. Only with timely pruning will new buds sprout quickly. When pruning, shorter branches can be left with 3 nodes, longer ones with 1 node, and generally 2 nodes. Leaving 3 nodes consumes more nutrients, while leaving 1 node often results in plump flower buds not forming, and leaf buds tend to produce leggy branches. Once leggy branches appear, cut them short in time. After pruning, apply a heavy fertilizer, and in about a month it will bloom again. After flowering, prune again in the same way. In this way, after more than a month of growth, it can bloom again. Through repeated pruning, jasmine can be made beautiful in form and abundant in flowers, with a rich fragrance that refreshes the heart and mind, bringing you a kind of aesthetic enjoyment.
