Cultivation method of鸳鸯茉莉 (Brunfelsia latifolia)
This article will discuss topics related to the woody flower, 鸳鸯茉莉, including its cultivation method. Detailed content will be shared next.
鸳鸯茉莉 is a perennial evergreen shrub. It is native to Central and South America. It prefers a hot, humid, and well-lit climate, and thrives in loose, fertile, well-draining, slightly acidic soil. It can tolerate semi-shade, drought, and poor soil, but dislikes waterlogging and is sensitive to cold. The optimal growth temperature is between 18-30℃.
In South China, 鸳鸯茉莉 can be planted in the ground or in pots. In the Yangtze River Valley and northward, it can only be potted. During the growing season, 鸳鸯茉莉 requires ample light and water-fertilizer balance, timely pruning of strong branches to promote side branches and control the shape of the crown. To encourage more blooming, water should be slightly reduced before the blooming period, and normal water and fertilizer management should resume once the flower buds appear.
鸳鸯茉莉 has a weak growth habit but many branches, with two-colored flowers and a fragrant aroma. It is suitable for decoration in buildings, courtyards, parks, or as a flowering hedge, and can also be potted for display. For home potting, a mixture of decomposed leaf soil, garden soil, and sand (in a ratio of 5:3:2) should be used as the potting soil. It is advisable to avoid using clayey soil, as it can easily cause root rot. When planting, place a layer of碎 hard plastic foam blocks at the bottom of the pot to enhance aeration and drainage, prevent root rot, and add 100 to 150 grams of bone meal or NPK compound fertilizer to the potting soil.
Every early spring, repot and change the soil, leaving about 1/3 of the old soil. It prefers warmth and fears waterlogging, requiring frequent fertilization and watering during the growing season. It is best to keep the potting soil slightly moist but not waterlogged, as excessive water can cause root rot. During the dormant season in winter, the soil should be slightly moist but not dry. It enjoys fertilizer, with NPK compound fertilizer applied every 10 to 15 days during the growing season. Avoid applying only nitrogen fertilizer, as it may cause the branches and leaves to grow excessively with fewer flowers. No fertilization is needed during the dormant period.
鸳鸯茉莉 loves sunlight and warmth and is not cold-resistant. It should be placed in a sunny courtyard, rooftop garden, or on a south or west-facing balcony during the growing season. However, it should be slightly shaded around noon in the summer, as excessive sunlight can cause the leaves to turn yellow. When the temperature drops to about 5℃ in winter, it should be moved indoors to a sunny windowsill. It can safely overwinter at temperatures above 3℃, and can even continue to bloom at around 20℃.
Proper pruning can enhance the beauty of the plant. For 鸳鸯茉莉 placed on a balcony, it is important to maintain a pruning height of 30 to 40 centimeters for a round canopy. When repotting in early spring, prune to a height of 15 to 20 centimeters, and the strong branches that are cut can be used for propagation. After blooming, a light pruning of the residual flowers and inner branches is sufficient.
Propagation can be done through cutting or layering. For spring cuttings, use 2-year-old branches, and for autumn cuttings, use semi-mature branches of the current year, about 10 centimeters long. Remove the lower leaves, dip in Vitamin B12, and insert into a plain culture soil. Seal with plastic film to maintain 80% to 90% humidity, and roots can develop in about 60 days. Spring cuttings can be transplanted into pots in the autumn, while autumn cuttings should be left in the seedbed to overwinter and transplanted in the following spring.
In addition, in the autumn, select branches near the pot surface, strip the bark for 1.5 to 2 centimeters, and after 50 to 60 days in the soil, roots can develop. For spring layering, cut the plant away from the mother plant in the autumn to transplant, while for autumn layering, cut away in the following spring to transplant.
