How to raise clematis, culture methods and precautions of clematis / pay attention to ventilation

Clematis is a kind of plant with high ornamental value, supported by the queen of rattan flowers, and it is also a kind of plant loved by many breeding enthusiasts, but there are still many aspects that need to be paid attention to if you want to raise it well. About how to raise clematis, what are the breeding methods and precautions of clematis? Next, the editor will take you to learn about it.

1. How to raise clematis / pay attention to ventilation

About how to raise clematis, in fact, there are many aspects that need to be paid attention to, and the environment is particularly important for its growth. In the process of breeding it must be the ventilation of the main environment, otherwise it is easy to appear diseases and insect pests and other phenomena.

II. Culture methods and matters needing attention of Clematis

1. Soil selection

Among the culture methods and matters needing attention of clematis, the choice of soil is a part that needs to be paid attention to, and it is best to choose alkaline soil with good drainage, which is beneficial to clematis better absorption of nutrients.

two。 Watering management

There are also many things to pay attention to when watering clematis. You can choose more watering when the weather is hot in summer and reduce the amount of water when the weather is colder in winter. It is also important to note that stagnant water is strictly prohibited when watering clematis, otherwise it is easy to have rotten roots.

3. Fertilization requirements

Fertilizer is one of the main nutrients of clematis, and it is also an essential part of its breeding process. You can choose to apply fertilizer frequently during the growing period, usually once a week. When winter is approaching, you can choose to apply fertilizer once, and then you don't have to apply it for the whole winter.

4. Illumination control

Spring and autumn are the most suitable seasons for clematis to grow, and they can be placed outside all day to receive light. However, when the summer weather is relatively hot, it needs to be moved to indoor semi-shady breeding, otherwise it may lead to the phenomenon of leaf yellowing when the sunshine is too strong. It is also important to note that a ventilated environment must be maintained when placed indoors.

Culture methods and matters needing attention of Clematis

Clematis culture method, clematis is born in hilly shrubs in low mountain areas. Like fertile, well-drained alkaline loam, avoid stagnant water or summer drought and can not retain water. Strong cold resistance, can withstand-20 low temperature. If there are red spiders or leaf-eating pests, ventilation should be strengthened. Clematis is rich in color, with a light fragrance, great ornamental value, loved by many people, the clematis culture methods and matters needing attention.

Culture method of Clematis 1. Watering

Clematis is very sensitive to moisture and should not be too wet or too wet, especially in the summer high temperature period, the matrix should not be too wet. Generally, it is watered every 3-4 days during the growing period, when the substrate is dry but the plant does not wilt. During the dormant period, as long as you keep the matrix moist. Do not let water accumulate on the leaf surface or at the base of the plant when watering, otherwise it is easy to cause disease.

2. Temperature

The optimum temperature for clematis growth was 15: 17 ℃ at night and 21: 25 ℃ at day. When the summer temperature is higher than 35 ℃, it will cause clematis leaves yellowing and even falling leaves, so cooling measures should be taken in summer. In November, the temperature continues to drop, and clematis will enter a dormant period when it is below 5 ℃. In December, Clematis completely entered the dormant period, and the leaves began to fall in the first and second weeks of the dormant period.

3. Pruning

The purpose of Clematis clematis pruning is to open more flowers, usually once a year, to remove some overdense or thin branches, and to make the new branches extend in all directions. The time of pruning should be determined according to the flowering period of different varieties. Early flowering varieties (flowering from April to May) should be pruned after flowering, that is, from June to July, to remove the excess branches, but the Lignified branches should not be cut off. If pruning before then, it will lead to the failure of flowering in the same year.

4. Lighting

Clematis requires more than 6 hours of direct light a day, which is very beneficial to its growth, although spots can occur in hot weather. Potted clematis is cultivated under full light from autumn to early spring of the next year without shade. After entering summer, it is necessary to prevent strong direct light and appropriate shade. Otherwise, it is easy to cause the leaves of clematis to be aged, withered and yellow and grow poorly.

5. Fertilization

Before sprouting new buds in late February or early March, clematis can apply a little compound fertilizer with a npk ratio of 15:5:5 to accelerate growth, and topdressing phosphate fertilizer once in April or June to promote flowering. Usually use 150mg / kg 20:20:20 or 20:10:20 water-soluble fertilizer, in the growth period to 200mg / kg, spray 2 times 3 times a month.

Reproduction method

A, sowing: the original seed of Clematis can be propagated by sowing, germinate after sowing in spring for about 3-4 weeks, and germinate in autumn when spring is warm.

B, pressing: clematis is propagated in March with one-year-old mature branches, usually rooting within one year.

C, ramet: clematis tufted plants, can be ramified.

D. Cutting: cutting is the main propagation method for hybrid clematis cultivars.

Matters needing attention in clematis culture

1. Clematis in poorly drained clay or light sandy soil, mix-shovel peat soil or humus after digging loose at the bottom of the hole, and use stones or rubble at the bottom where water may accumulate, 25 cm higher than the surrounding soil surface.

2. Pay attention to adequate water supply in the first few months after clematis planting, and the diameter of the water supply range is not less than 50 cm, so that the root can stretch around, and special attention should be paid to drainage at the same time.

3. Clematis pest is harmed by red spider and diamondback moth, which is sprayed with 1000 times of fenitrothion EC.

4. When clematis is planted, the hole is generally 40 cm deep and 60 cm in diameter. After loosening the hard soil at the bottom of the hole, a large amount of humus is put in, and then the topsoil mixed with bone powder is added. Note that the branches are brittle and easy to break, so attention should be paid to attraction and fixation.

5. The disease of clematis has Fusarium wilt, which is likely to occur on rainy days in summer, when the temperature rises sharply, the branches suddenly wither, and new techniques often sprout in autumn or the following spring. Others have powdery mildew, virus disease, etc., sprayed with 1000 times of acetic acid solution of 10% antibacterial agent.

Clematis value 1. Ornamental value

Clematis clematis branches and leaves are sparse, some flowers are large and colorful, some florets gather into large inflorescences, funny and unique, it is an indispensable good material in climbing greening, and has a certain ornamental value.

2. Beautify the household use

Clematis can be planted on the walls and windows of household buildings, or attached to trees and shrubs in the courtyard, planted between rockery and rocks, attached to styles, gates and fences, and can also be watched in potted plants. it is a good choice to beautify the home environment.

Culture methods and matters needing attention of Clematis

Clematis soil requirements

Like fertile, well-drained alkaline loam, avoid stagnant water. The most important thing is that the basin soil must be breathable, if possible, choose some better soil, after strict disinfection, poor conditions can use perlite and peat, try not to dig garden soil pot.

Watering requirements of Clematis

Clematis growing well requires smooth root breathing and alternating wet and dry watering. To let the basin soil dry time, generally 2-3 cm below the soil surface dry, can be watered. If it is a plastic basin, it is another matter. According to the weight of the basin soil, it should be watered if it becomes lighter; if you observe the basin soil, if you look at the basin soil, you need to water it. Watering must be thoroughly watered. The concept of watering thoroughly is at least water flowing out from the bottom of the basin. Pay attention to timely ventilation after watering.

Lighting requirements of Clematis

Potted clematis were cultivated in full light from autumn to early spring of the next year, without shade. Strong light after entering summer will lead to aging and yellowing of clematis leaves, poor growth, and need proper shading. In indoor maintenance, it is necessary to ensure at least 4 hours of sunlight every day, otherwise clematis will not grow well.

Fertilization methods of Clematis

Adhere to the application of thin fertilizer frequently, avoid eager for quick success and quick profit. There are many varieties of clematis, some of which are not fertilizer-tolerant, such as long petals, evergreen, Montana, and should be less fertile when maintained. In addition, when applying fertilizer to young seedlings, it is best to use only promoting root and slow seedling fertilizer, not heavy fertilizer. Winter is the best season for clematis to apply fertilizer, basically once, manage for a few months!

Matters needing attention in Clematis Culture

Newly planted clematis need to pay attention to sufficient water in the first few months, so that the roots have enough water to extend.

Clematis is a vine whose branches are brittle and easy to break, so pay attention to timely inducement and fixation.

Clematis cultured on the open-air balcony should pay attention to timely drainage, especially in the rainy season, can properly accept the rain, but not excessive, move to the indoor at the right time.
