The latest culture methods and matters needing attention of Jasper

Jasper is known as Douban Green, alias watercress, Douban Ruyi, etc., for the Piperaceae grass Pepper herbs, stem creeping, multi-branched, can be potted ornamental, but also has medicinal value, internal treatment of rheumatoid arthritis, bronchitis, external application to treat sprains, carbuncle, boils and so on, let's take a look at Jasper's breeding methods and matters needing attention!

The growing environment of Jasper

Jasper was born on wet stone or dead trees, like warm and humid semi-shady environment, the suitable temperature for growth is about 25 ℃, the lowest can not be less than 10 ℃, can not bear high temperature, requires high air humidity, avoid direct sunlight, like loose, fertile, well-drained moist soil. It is distributed in Taiwan, Fujian, Guangdong, Guangxi, Guizhou, Yunnan, Sichuan, southern Gansu and southern Xizang, and abroad in America, Oceania, Africa and tropical and subtropical Asia.

The breeding method of Jasper

Jasper is often propagated by cutting and dividing plants. The top branches of the cuttings are selected from April to May, the cuttings are about 5 cm long, and the upper part retains 1 or 2 leaves. After the cut is dried, it is inserted into the wet sand bed. You can also insert leaves, cut the leaves with petioles with a knife, dry them slightly, then insert them obliquely on the sand bed, and take root in 10-15 days. In a greenhouse with temperature control equipment, it can be carried out all year round. Ramets are mainly used for the reproduction of colored leaf varieties.

Culture method of Jasper

1. Soil: Jasper likes to grow in loose and fertile sandy soil with good drainage and rich in humus, and its growth potential is poor in clay. Generally, the substrate can be mixed with rotten leaf soil, river sand and a small amount of mature organic fertilizer, and peat soil and perlite can be mixed under certain conditions.

2. Lighting: Jasper likes semi-overcast or scattered light, except for sufficient light in winter, shading is needed in other seasons, especially in summer. If placed in a shady environment, it is easy to grow, the branches grow, and the ornamental is reduced, which is not advisable. Under the semi-overcast condition, the leaf color is brighter and the gloss is better, especially the variegated leaf variety, the demand for sunlight is a little higher.

3. Temperature: Jasper likes warm environment, the suitable temperature for growth is between 20 and 30 ℃, the overwintering temperature is better kept above 10 ℃, the growth stops below 10 ℃, and it is easy to freeze under 5 ℃.

4. Humidity: Jasper likes the humid growth environment, grows luxuriantly in the humid environment, the leaf color is bright, and the foliar spray should be strengthened or sprinkled in the growing environment when the temperature is high or the air is dry, so as to maintain high air humidity, which is extremely beneficial to the growth of plants. It can also adapt to a short dry environment, but not for a long time, generally should be kept at about 70%.

5. Watering: Jasper prefers water and is not resistant to drought. It should be watered frequently during the growing period, and more water should be watered when the temperature is higher than 25 ℃ or when the air is dry, but it should also be prevented from waterlogging. When the temperature is lower than 25 ℃, it should be watered thoroughly when the surface of the basin soil is dry. When the temperature is less than 10 ℃, it can be dried for several days without watering.

6. Fertilization: a small amount of fertilizer is needed when the temperature is higher than 18 ℃, and less or not when the temperature is lower than 18 ℃ or higher than 30 ℃. Fertilization should be carried out in a small amount and many times, and diluted fertilizer solution instead of clear water is the best. It is not resistant to raw fertilizer and thick fertilizer, and it is easy to cause fertilizer damage. Foliar spraying fertilizer solution can also be used for fertilization, and the effect is good. Fertilizers are mainly nitrogen fertilizer and potassium fertilizer, followed by phosphate fertilizer.

7. Pruning: Jasper's newly propagated seedlings will pick the heart to increase the number of branches when the seedling height is about 10 centimeters, so that the plant type is fuller and the appreciation value is higher. The pruning of large plants is generally determined according to the growth trend, short cut and long branches, which can be used as cutting material, easy to take root, can be planted in clean river sand or vermiculite, or directly in sandy soil.
