Potted Night-blooming Jasmine (Cestrum nocturnum) Cultivation Methods and Management Techniques
Night-blooming jasmine is an ornamental plant native to subtropical regions, with a fresh fragrance that is especially stronger at night. Its flowering period is long, blooming continuously from May to October. The flowers can not only be enjoyed for their scent and to repel mosquitoes, but are also edible and medicinal. It is often potted for courtyard ornamentation. This article will mainly discuss its management techniques.
I. Potting Soil Management
Night-blooming jasmine is not tolerant of waterlogging and prefers loose, fertile, well-drained, slightly acidic soil. The potting soil can be prepared by mixing garden soil and leaf mold in a 1:2 ratio; such soil is suitable for the branches to take root and sprout.
II. Temperature Management
Night-blooming jasmine is not cold-tolerant; the minimum temperature for overwintering should not be lower than 8°C. If the temperature is too low, the leaves will turn yellow and drop off.
III. Light Management
Although night-blooming jasmine likes abundant sunlight, it dislikes harsh exposure. In summer it must be shaded or placed in a semi-shaded, well-ventilated spot. In other seasons it can receive full sunlight.
IV. Watering Management
Night-blooming jasmine likes a moist environment, is drought-tolerant and afraid of waterlogging. Watering should keep it moist but not waterlogged, maintaining the soil in a moist state. In summer, during vigorous growth, it can be watered once a day, while also spraying water on the leaves to increase humidity. After the leaves drop in winter, stop watering and just keep the soil slightly moist and on the dry side.
V. Fertilization Management
During the growing season, apply a thin cake-based liquid fertilizer once every 10-15 days. In the north, where the water is somewhat alkaline, alum fertilizer water can be applied. In May, when it enters the flowering period, potassium dihydrogen phosphate can be sprayed on the leaves to supplement phosphorus and potassium fertilizer.
VI. Pruning Management
Prune after flowering every autumn, cutting the branches back to 10-15 cm to encourage more new branches, help reduce height, plump up the tree shape, and produce more flowers the following year. At the same time, remove overly dense branches and the like.
The fragrance of night-blooming jasmine is too strong, and people will feel uncomfortable after smelling it for a long time, so it is not suitable for growing indoors.
How to pot night-blooming jasmine? Cultivation methods for potted night-blooming jasmine
Night-blooming jasmine is native to southern China, growing in hillside shrub thickets. It is now cultivated in all southern provinces and regions. It likes a warm, humid, sunny, well-ventilated, dry climate and an environment with good drainage and loose, fertile soil. It is drought-tolerant, tolerant of poor soil, not tolerant of waterlogging, and not cold-tolerant. Now let us take a look at how to grow potted night-blooming jasmine!
Potting Soil Preparation
Night-blooming jasmine likes loose, well-drained, organic-rich, slightly acidic soil. The potting soil is generally made by mixing 3 parts peat soil or leaf mold, 2 parts coarse river mud, and a small amount of farmyard manure. When potting, fill about 1/5 of the bottom depth with granular crushed bricks to facilitate pot drainage, and use the prepared potting soil for the upper part.
Growing Environment
Potted night-blooming jasmine requires well-ventilated environmental conditions. From early May to the end of September, it should be placed in a sunny spot in the yard or on a balcony for care. Although it likes abundant sunlight, at noon in summer it should avoid harsh sun exposure.
Fertilization for Potted Plants
During the growth process of night-blooming jasmine, a liquid fertilizer should be applied once every 10 to 15 days. Starting in late April, apply a thin liquid fertilizer once every half month. From mid-May onward, this can ensure continuous flowering. If high-efficiency humic acid liquid fertilizers such as Chunquan 883 or Huimanfeng are applied, the effect will be even better.
Watering for Potted Plants
Summer is the peak growing season for night-blooming jasmine. In addition to sufficient fertilizer, the potting soil must be kept consistently moist, and if necessary, water twice a day. If it is a seedling, spray water on the leaves 1 to 2 times a day.
Temperature Management
Potted night-blooming jasmine should be moved into a shed or indoor room in mid-to-late October each year. The shed or room temperature should be maintained at 8°C to 12°C. If the temperature is lower than 5°C, the leaves will turn yellow and drop off, leading to death.
Repotting at the Right Time
Repotting potted night-blooming jasmine is best done in early April in spring before it is moved outdoors. When repotting, remove some of the old soil and old roots, replace with new culture soil, and perform heavy pruning to encourage new branches. After repotting, keep the potting soil moist, but there must be no standing water in the pot. If the young leaves are found to droop slightly after repotting, water promptly.
Plant Shaping
In potted management, night-blooming jasmine needs a trellis to be set up. After the plant climbs onto the trellis, pinch the tips promptly to encourage more branching. After flowering, promptly cut off the spent flower stalks and apply additional fertilizer. After the flowers fade, cut away dead and dry branches and overly dense branches, and shorten leggy growth.
Pest and Disease Control
The main pests of night-blooming jasmine are mites and scale insects, and the disease is fusarium wilt. To control mites, use 800x dilution of Kangman 23 emulsifiable concentrate, 2000x dilution of 73% Kelmite, etc. To control scale insects, use 600-800x dilution of 40% dimethoate emulsion. To control fusarium wilt, use 600-800x dilution of Kuwei Like, 600x dilution of 50% carbendazim, etc. If diseased plants with fusarium wilt are found, they should be removed promptly, taken outside the garden and burned, and the soil around the diseased plants should be turned over and sprinkled with quicklime; replant after 1 month.
