How to raise a cold spray

How to raise cold water, cold water, also known as snow grass, flower and leaf nettle, is a perennial herb of Urticaceae. Its underground rhizome is horizontal, the plant height is 30cm to 50cm, the aboveground stem is fleshy and translucent, the internodes are dilated and much branched. Leaves opposite, egg-shaped, leaf tip pointed, three main veins are very obvious, veins have silver-white longitudinal stripes, leaf veins sunken, leaf slightly wrinkled, leaf back light green.

Cold spray has strong adaptability, like warm, moist and bright light. It is not cold-resistant and shade-tolerant. The suitable temperature for growth is 15-25 ℃, and the winter temperature is not lower than 5 ℃. Sensitive to light, when exposed to strong light, the leaf becomes smaller and the leaf color is not bright; if the light is too weak, the Internode becomes longer and the stem is soft, so that the plant becomes scattered, where the scattered light is sufficient, the leaf color is green and white, the Internode is short and compact, and the leaf surface is bright and shiny.

The propagation of cold water spray is generally done by cutting. the shoot is cut in the spring and autumn, the cuttings are 8-10 cm long, and the leaves at the base are cut off. It can take root about 10 days after cutting, and the survival rate is very high. Cold water flowerpot after growing faster, fertilizer and water must be adequate supply, summer in addition to watering every day, but also often spray water on the leaves. 0.3% potassium dihydrogen phosphate solution is applied every half month.

Sufficient sunshine is needed in winter and watering should be reduced appropriately. During the growth period, you should often pick the heart, and when the seedling is 15 centimeters high, you begin to pick the heart to promote the lateral branches and maintain a low and plump plant shape. When the plant grows too high in summer and autumn, the top is cut off to keep the plant shape luxuriant and compact. In the spring of the following year, the old plant was truncated again, leaving only two basal segments of the stem, and new branches and leaves will sprout again from the culm base half a month later.

How to raise cold water, cold water culture methods and precautions / fertilizer and water should be sufficient

Cold spray is a kind of highly ornamental plant, which can be seen in many parts of our country, and there are many people who raise it in our country, but if we want to raise it well, there are many places that need to pay attention to, so how to raise it? What are the methods and matters needing attention in cold spray culture? Next, the editor will take you to learn about it.

First, how to raise cold water and understand the habits

If we want to know how to raise cold water, we must first understand its growth habits. It is a light-loving plant, so we should maintain sufficient light when raising it. In addition, watering, fertilization and other aspects also need to be paid attention to. Details are introduced in the following cold water culture methods and matters needing attention, let's take a look.

2. Methods and points for attention of cold water spray culture

1. Soil selection, good drainage.

When we cultivate cold water, we should first choose soil, which is a step to lay a good foundation. Generally, it is best to choose a relatively loose humus soil, which has good drainage and air permeability and can make cold water grow more healthily, and it is not easy to accumulate water if you use this kind of soil.

two。 Fertilization requirements, once every two weeks during the growing period

In the growth process of cold water, fertilizer is one of its main nutrients, especially after entering the growth period, it has a great demand for fertilizer, basically every two weeks need to be fertilized, so that it can grow more robust. However, when we apply fertilizer, we should pay attention to that the fertilizer needs to be diluted with water before fertilization, so that it can be better absorbed.

3. Watering management, control of watering quantity

When we water the cold water flowers, we should keep the basin soil dry but not cracked, moist but not wet is the best, to the summer when we can often spray water on the leaves, so as to maintain the moisture of the leaves, but also play a role in cleaning the leaves. When we are watering, we should pay attention to control the amount of water, it is best not to water too much, otherwise it will easily lead to the phenomenon of rotting roots.

4. Lighting requirements, raised in astigmatism

In the cold water spray culture methods and precautions, the light is also a point that needs to be paid attention to. Although the cold water spray likes light, it is not resistant to strong light, so we had better breed it in the place of sunlight scattering. because if the light is too strong, it is easy to burn the plant and cause its leaves to turn yellow, and if the light is too dark, it will make the leaves slowly turn green.

5. Temperature control, 15 ℃-25 ℃

When we breed cold splash, it is also very important to let it grow at a comfortable temperature, the more suitable environmental temperature for growth is between 15 ℃-25 ℃, we can do a good job in temperature control when breeding, especially after entering winter, temperature control is particularly important, cold splash is less hardy, so the ambient temperature in winter had better not be lower than 5 ℃.

6. Pruning management, pick the heart once after putting on the basin

Cold spray is more resistant to pruning, we can pick the heart of the cuttings once after the cuttings are potable, and wait until the new lateral branches grow to 4 leaves, and then leave 2 leaves to pick the heart, so repeated operation, can form a multi-branched full hemispherical plant shape. When the old branch of the cold spray grows too high, we also need to prune it once to maintain its plant type.

7. Pest management, timely treatment can not be trusted.

When we cultivate cold water flowers, if we raise them improperly, it is easy to have problems such as diseases and insect pests, which do great harm to plants and must be dealt with in time, because the longer the time drags on, the more difficult it is to cure them. Specific prevention and control methods Xiaobian in the cold splash pest control article has a detailed introduction, we can understand.

How to raise Cold Water Flower Culture methods and matters needing attention

Cold spray is a kind of evergreen foliage plant with beautiful leaf color and beautiful pattern, and it is very easy to grow and has a strong ability to adapt to the environment. Although cold water is an ornamental plant, it can also produce particularly beautiful flowers at the same time. So how to raise cold water? Let's get to know it with the editor.

How to raise a cold spray

1, soil: cold pot soil had better use humus-rich, loose, fertile loam. Keep the basin soil moist and should not be too wet, otherwise the root is perishable and requires high air humidity. Rotten organic fertilizer should not be used too much urea, such as nitrogen fertilizer is easy to grow crazy, which is not conducive to the appearance of the plant. When the phosphorus and potassium fertilizer is insufficient, the markings on the leaves are easy to fade.

2. Lighting: cold spray is a kind of indoor flower with beautiful leaf color, which is very shade-resistant, but prefer sufficient light, and should avoid direct light. Flowerpots are placed in the north window in summer and in the south window in winter. If the light is too dark, the color of the leaves will fade. If the sun is too strong, the leaves will be burned. The suitable temperature for growth is 18-22 ℃, and the overwintering temperature should not be lower than 7 ℃.

3, fat water: cold water flowerpot soil remains dry but not cracked, moist but not wet is better. Spraying water to the leaf surface in summer can keep the leaf surface clean and shiny, and the leaf surface sprays less water in winter, otherwise the leaf surface will appear black spots, or even black and rotten. Watering 28% or 37% liquid nitrogen fertilizer at a time in about two weeks during the growing period makes the plant strong. After autumn, increase the application of phosphorus and potassium fertilizer to strengthen the stem and prevent lodging.

4. Pruning: the cold spray is resistant to pruning, and the cuttings can be removed once after the cuttings are put on the pot. when the new lateral branches grow to 4 leaves, 2 leaves are left to pick the heart, so repeatedly, a multi-branched plump hemispherical plant shape can be formed. When the old plant grows too tall, it can leave the base 2-3 nodes when changing pots in spring, re-cut it short, pick the heart 2-3 times after sending new branches, and form a short and compact plant shape.

5. Diseases and insect pests: the common leaf spot disease of cold water spray can be prevented by spraying 200 times Bordeaux liquid. The basin soil is too wet, which is easy to produce root rot, so it can be irrigated with 1000 times solution of topiramate. When root nodule nematodes are found, 3% carbofuran can be applied to control. It is harmful to scale insects and is sprayed with 1000 times of omethoate. If the beetle bites the leaves, it can be killed manually or sprayed with 1000 times the liquid of trichlorfon.

Culture methods and matters needing attention of cold water spray

The main results are as follows: 1. The cold spray should be changed at least once a year in spring, fertilized in about a week during the growth period, and fertilized once with nutrient solution.

2. When the cultivation time is too long and the growth is slow, it should be pruned in time, otherwise it will lead to the decrease of ornamental effect.

3. Cold spray likes strong scattered light, covering more than 70% of the sun in summer, the leaves will be burned if the sun is too strong, and there is no need for shading or slight shading in winter.

4. The temperature of cold water should be kept above 13 degrees Celsius when overwintering. If the long-term temperature is lower than 10 degrees Celsius, it will be hurt, but there will be no injury for about 5 ℃ in a short time.

5. Cold spray likes a humid environment and often keeps the spray moist and high air humidity. In the dry season, you can often spray water to the surrounding environment or foliage.

When does the cold water flower blossom

Cold water flower will blossom, cold water flower flowering is not very gorgeous, its flowers are dioecious. Inflorescences grow from leaf axils, with cymose flowers, yellow and white florets, very elegant. After the cold water blossoms, it will bear fruit. Generally speaking, the flowers and fruits of cold water have a certain ornamental value.

In fact, cold water blossoms in summer, its flowering period is from June to September, and its fruiting period is from September to November.

The growth habit of cold water spray

Cold water flowers are native to valleys, streams or shady places under forests, 300-1500 m above sea level. Found in Guangdong, Guangxi, Hunan, Hubei, Guizhou, Sichuan, southern Gansu, southern Shaanxi, southern Henan, southern Anhui, Jiangxi, Zhejiang, Fujian and Taiwan, and distributed in Japan and Vietnam.

Cold water flowers like warm, humid climate, like loose and fertile sandy soil, suitable for growth of 15 ℃ to 25 ℃, not low in winter.

Cold spray is a small foliage plant, occupying a relatively small space area is generally used to decorate the interior, many people like to plant in the room or office, not only beautiful but also can purify the air!
