Binary jasminum propagation and cultivation
For most women, the topic of jasminum propagation, especially binary jasminum, is worth exploring. Let's take a look together!
Also known as lovebird jasminum, it is native to tropical America. It prefers a warm and humid environment with plenty of sunlight, is not cold-resistant, flood-resistant, or intense sunlight-resistant, and requires well-drained, fertile, and loose slightly acidic soil. The winter temperature should not be lower than 10℃.
【Propagation Methods】
Propagation can be carried out through seeding, cutting, and layering methods.
The fruit is a capsule, spherical in shape, matures in autumn and winter, and after harvesting and drying, the shell is removed and stored for spring sowing the following year. Germination and growth are relatively easy and require no special management.
Cuttings can be made in spring and autumn. Spring cuttings use two-year-old branches, while autumn cuttings use mature branches of the current year. The cutting length is about 10 centimeters, with a substrate of vermiculite or half river sand mixed with peat soil, maintaining a temperature of 20-25℃, covered with plastic film to increase humidity. The ground temperature should be higher than the air temperature, otherwise, it is not easy to root.
Layering propagation is carried out in spring and autumn, selecting healthy branches about 15cm long. After ring stripping, wrap with mud strips, and roots can emerge in 50-60 days.
Thin branches are not easy to survive after cutting and can be propagated using the layering method, with a survival rate of over 95%. In spring, aerial layering is used, and roots can usually form in 50-60 days.
【Cultivation Management】
It prefers a warm and humid environment with plenty of sunlight, is not cold-resistant, flood-resistant, or intense sunlight-resistant, and blooms profusely under soft and sufficient sunlight. It requires well-drained, fertile, and loose slightly acidic soil, with a winter temperature not lower than 10℃. When the temperature drops below 12℃, the leaves will gradually turn black and fall off, and normal flowering occurs above 24℃. In dry northern climates, the leaf edges often become burnt, and it is necessary to maintain over 70% air humidity. Lovebird jasminum has weak cold resistance and wind resistance, and it is usually moved outdoors after mid-May. The main diseases include leaf spot and powdery mildew, which can be controlled by spraying 65% zinc sulfate wettable powder at 600 times. Pests include scale insects and cicadas, which can be killed by spraying 40% omethoate emulsion at 1000 times.
Potted plants usually use decomposed leaf soil or peat soil mixed with about 1/4 river sand and a small amount of basic fertilizer as the growing medium. The soil should be loose and not too heavy, otherwise, the roots can rot easily. It enjoys plenty of sunlight, and it can even be placed near the south window in summer, but if exposed to intense sunlight at noon, it should be shaded. It does not require high humidity and can adapt to the humidity of a general living room. Moderate watering is required, keeping the potting soil moist, and spraying water to increase air humidity when it is dry. If in the dormant period, the amount of water should be reduced. Strong-growing plants should be repotted every 1-2 years. In the north, when entering the medium-temperature greenhouse for winter, the flowering period is postponed, usually starting in April and lasting until mid-to-late June. In this case, pruning or repotting should be done at the end of September of the previous year. After flowering, pruning and shaping are required to remove withered and diseased branches to maintain an attractive plant shape. After new shoots appear, apply liquid fertilizer 3 to 4 times, with the period from April to September being the vigorous growth period, applying liquid fertilizer every 1-2 weeks. The normal flowering period is in early winter or early spring, but if the temperature is controlled at 24℃, it can also bloom in other seasons.
This article provides a comprehensive introduction to the propagation and cultivation of binary jasminum, hoping to bring some knowledge about green plants to greenery enthusiasts.
