The growth habits of Star Jasmine

Star Jasmine has a certain cold tolerance. If it is used for indoor pot cultivation, it is suitable for cultivation anywhere in China. However, if it is used for open-air cultivation of flowers, it needs to be limited to the south of the Yangtze River.

Star Jasmine also has a certain drought tolerance and a little waterlogging tolerance, which requires good drainage of the soil.

Morphological characteristics of Star jasmine

Star jasmine is an evergreen woody vine with an inconspicuous lenticel on the stem. Branchlets, young petiole and leaf are abaxially pubescent, old branches and leaves glabrous.

Leaves are leathery, elliptic to ovate-elliptic or broadly obovate, 2 -- 6cm long, 1 -- 3cm wide. Old leaves are nearly green or light green, the first round of new leaves pink, a few 2-3 pairs of pink leaves, the second to the third pairs of pure white leaves, between pure white leaves and old green leaves there are several pairs of spotted flowers and leaves, the whole plant leaves rich in color, can be described as colorful.

Star jasmine is a light-loving plant with strong shade tolerance. It likes the acidic and neutral soil environment with high air humidity and good drainage. It has strong disease resistance and vigorous growth, which is similar to the Chinese native jasmine. The change of leaf color is related to illumination and growth conditions. The bright color expression needs good illumination and vigorous growth conditions.

Star Jasmine is one of the newly developed and most highly praised ground cover trees in Japan. This variety stands out among the existing garden afforestation groundcover plants with its advantages of showiness, natural strength, good resistance and extensive cultivation and management.

Growing methods of Star Jasmine

Temperature: Star Jasmine likes warm, suitable temperature for growth between 18 and 25 degrees. Star Jasmine has strong adaptability, cold and high temperature resistance. In winter, it can endure the continuous minus 5 degrees of low temperature environment; In the middle of summer, even if the temperature exceeds 35 degrees, it does not affect normal growth.

Humidity: Star Jasmine likes wet. In the maintenance period, you can often spray water on the leaf or the surrounding water humidification. In the humid environment, it is helpful for growth. It should be noted that when the leaf is sprayed, in addition to maintaining a good ventilation environment, but also to avoid the period of strong light, in order to prevent water droplets on the leaf, resulting in burning phenomenon.

Light: Star Jasmine likes full light, but also tolerant of shade. During the growing season, to make the leaves colorful and beautiful, you need an environment with plenty of light, especially in autumn, winter and spring.When the temperature is high in summer, shade can be appropriate. It should be noted that there is sufficient light, the leaves will become beautiful; If the light is insufficient for a long time, although the new leaves will be pink, but the old leaves will turn green, the effect will be discounted, which is the place to pay attention to.

Soil: The soil requirements are not strict, suitable for loose breathable, good drainage of neutral or acid soil.

Watering: see the topsoil, dry and wet alternately. Star Jasmine is resistant to drought and flood. If the soil is dry for too long, leaves will fall. In this case, it needs to be watered in time, and after a period of time, new leaves will sprout again. Star Jasmine likes water, in the growth period, watering frequency can be increased appropriately. In summer, the pot soil needs to be kept wet for a long time. In winter, the growth will slow down, watering frequency can be appropriately reduced, in case the soil is too wet for a long time, resulting in retting root phenomenon.

Fertilization: the requirement of fertilizer is not high. In the spring and autumn growing period, each applied a compound fertilizer, to ensure the balance of the elements. In winter and summer have high temperatures when the growth will be relatively slow, it needs less fertilizer, and can be suspended with fertilizer.

Diseases and insect pests: due to the branches and leaves have a certain toxicity, itself less diseases and insect pests, usually relatively easy management; However, in the summer of hot and humid high temperature, poor ventilation, easy to appear powdery mildew, can be timely pruning sick branches and leaves, with carbendazim and other bactericidal drugs for prevention and control.

Star Jasmine propagation methods

Usually used cuttage propagation, suitable for spring and autumn two seasons, branches can be combined with pruning.

Usually with annual branches, this cutting effect is better.

The method is: cutting matrix can be used perlite, vermiculite, peat, etc., according to a certain proportion of mixing. Cutting branches generally cut growth degree 10-15 cm small section, stem end to leave 2-3 to the leaves, inserted into the soil depth of 3-5 cm is appropriate, cutting density according to the actual demand. Pay attention to the regular combination of water and spraying chlorothalonil, carbendazim and other agents, in order to prevent substrate and cuttings disease.In addition, but also for cutting seedlings to build a small arch shed covered with film, appropriate shading, and maintain the temperature in the shed at 28℃, humidity in about 90%. Paying attention to each watering should not make the soil too wet, keeping the leaf surface moist is appropriate. After the adventitious roots grow out of the branches, the seedlings can be refined basically after cultivation for 2 months. After the seedlings are refined, they can be transplanted and fixed.

The flower language of Star Jasmine

Star Jasmine's motto: Good luck with all virtues.

Star Jasmine main values

The ornamental value of Star Jasmine is reflected in three levels of leaf color, namely, the color group composed of red leaves, pink leaves, pure white leaves, variegated leaves and green leaves, which is very similar to a bunch of flowers in full bloom.

To achieve the best color effect, intensive pruning is required in spring to promote sprout, increase ornamental shoots, and form compact clumps of plants.

In the garden, Star Jasmine is an extremely beautiful ground cover plant material, which can be planted in the isolation belt under the urban street trees or covered as the slope protection vines. It can replace the potted flower setting in the current parks and modern facilities, to overcome the shortcoming of short ornamental period and high cost of frequent replacement of potted flowers. In addition, it can also be used as an excellent ornamental plant for home potted plants.
