How to raise potted Jasper?

Jasper, also known as Douban Green, watercress, Douban Ruyi, etc., is an herbaceous plant of the family Piperaceae. it is often cultivated in white plastic pots and white porcelain pots on coffee tables, decorative cabinets, ancient shelves, and desks. or any branches spread and hang in front of the indoor window or bathroom, which has a certain purification effect on formaldehyde, xylene, secondhand smoke and so on. Let's take a look at how to raise potted Jasper.

Growth habits of Jasper

Jasper originated in the West Indies, Panama, northern South America, and then introduced to China, is now produced in Taiwan, Fujian, Guangdong, Guangxi, Guizhou, Yunnan, Sichuan and southern Gansu and southern Xizang and other places, like warm and humid environment, growth temperature about 25 ℃, the lowest not less than 10 ℃, not resistant to high temperature, higher air humidity, avoid direct sunlight, like loose fertile, moist soil with good drainage.

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. Jasper can also be inserted into 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 the greenhouse with temperature control equipment, it can be carried out all the year round, and the ramet is mainly used for the reproduction of colored leaf varieties.

How to raise potted Jasper?

1. Soil: Jasper likes to grow in sandy soil that is loose and fertile, well drained and rich in humus, and is not suitable for growing in clay, so the matrix is usually mixed with rotten leaf soil, river sand and a small amount of mature organic fertilizer. a better substrate can be cultivated with optional peat soil and perlite.

2. 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 Kongqi is dry, but it should also be prevented from waterlogging. When the temperature is below 25 ℃, the basin soil surface should be watered thoroughly when the temperature is less than 10 ℃. It can be dried for several days without watering.

3. Humidity: Jasper likes the moist growth environment, grows luxuriantly in the humid environment, and has bright leaves. When the temperature is high or Kongqi is dry, it is necessary to strengthen foliar spraying or sprinkle water in the growing environment to maintain high humidity of Kongqi, 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%.

4. 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 ℃. The change of temperature directly affects the color of leaves. The optimum temperature of colored leaves in winter is 18 ~ 20 ℃, and that of green leaves is about 15 ℃. If you are afraid of heat in hot summer, you can spray water under the shade to cool down, but it should be noted that overheating and humidity will cause stems and leaves to blacken and rot.

5. 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, grow between branches, and reduce ornamental, which is not advisable. Under the semi-overcast condition, the leaf color is brighter and the gloss is better, and the special variegated leaf variety has a slightly higher demand for sunlight.

6. Fertilization: Jasper needs a small amount of fertilizer when the temperature is higher than 18 ℃, and less or not when the temperature is lower than 18 ℃ or higher than 30 ℃. Fertilization had better be carried out a few times, and it is best to use diluted fertilizer solution instead of clear water irrigation. It is not tolerant 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 has strong branching ability and grows rapidly. usually, we should pay attention to pruning, cutting off the branches that are too high and too dense, which can not only improve the air circulation between branches and stems, but also keep the plant shape beautiful. For newly propagated seedlings, it is necessary to pick the heart to increase the number of branches in the seedling height of about 10 centimeters, and the pruning of large plants is generally determined according to the growth.

Points for attention of Jasper

1. Jasper has fewer diseases and insect pests, and the general diseases are caused by improper nursing and environmental discomfort, which can be gradually recovered after adjustment. The pests are mainly harmed by red spiders, but they can be prevented when keeping high humidity. When they occur, they can be prevented by wiping leaves with wet cloth or spraying special pesticides.

2. Jasper aquaculture in summer should strengthen air convection so that the temperature in its body can be released, put it in semi-shade, or shade it by 50%. At the same time, spray properly, 2-3 times a day.

3. Jasper should move to a brightly lit place for maintenance when breeding in winter, and wrap it with a film outside for the winter, but uncover the film every two days when the temperature is high at noon and let it breathe.

4. Jasper has many requirements for fertilizer and water, but she is most afraid of random fertilization, concentrated fertilizer and partial application of nitrogen, phosphorus and potash fertilizer. It is required to follow the principle of "frequent application of light fertilizer, less and more times, and complete nutrition".

5. Jasper is afraid of bright light, so she needs to keep it in the semi-shade or give it 70% shade. For indoor maintenance, put it in a brightly lit place as far as possible, and move to outdoor semi-shade or shade every one or two months, so that it can accumulate nutrients and restore its growth.
