How to grow hostas? The latest cultivation methods and precautions
Hosta is also called white crane immortal, and it is a perennial herbaceous plant of the lily family. It is also a native plant of China, and its planting area in China is very large. The ornamental value of hosta is very high, and the root part of the flower can also be used as medicine, having various effects such as heat-clearing and detoxifying, relieving cough and soothing the throat. So how should hosta be cultivated? Below, the editor brings you the cultivation methods and precautions for hosta. Let's take a look together!
1. Soil selection
Although hosta does not have very strict requirements for soil, hosta likes to grow in soil rich in humus, soft, and with strong permeability. Suitable soil can enhance the growth ability of hosta and can improve its ornamental value. If hosta is potted, then the culture soil should be prepared mainly with materials such as peat, perlite, and ceramsite, with the ratio controlled at 1:1:0.5. Soil selection is the first step in cultivating hosta, and also a very important step, so everyone should pay more attention to it.
2. Propagation methods
There are two propagation methods for hosta: division and sowing, but division propagation is generally the main method. After hosta grows for about one year, it can sprout about 3 buds, and at this time division propagation can be carried out. The time for division propagation is in March. Dig out the old plant, then dry it for about two days, making it lose water. When dividing, make sure the tool is sharp enough, and after division, apply an appropriate amount of charcoal powder to the wound. Generally, one plant can be divided into one bud per plant. After division, water thoroughly, and later do not water too much to prevent root rot. After division, plant separately to make them individual plants, and they usually bloom in the same year.
3. Temperature control
Hosta likes to grow in a warm environment, so growth in a high-temperature environment will be inhibited. Therefore, attention should be paid to reducing the temperature through methods such as ventilation and spraying water on the ground. At the same time, the temperature should not be too low, especially in winter, and good cold protection and heat preservation work must be done. If the temperature is below zero, potted hosta should be wrapped with plastic film, but it should be opened every two days to let the plant breathe, and after the temperature gradually rises in spring, the film can be removed.
4. Precautions
Hosta likes to grow in a humid environment, so attention should be paid to keeping the soil moist. In summer, water frequently, about twice a day. On rainy days and low-temperature days, water less or not at all, and note that the soil must not accumulate water. Then provide suitable light for hosta. Except in summer, hosta can receive sunlight in the other three seasons, but in summer, direct sunlight should be prevented, and shading work should be done well. Finally, do a good job in fertilizing, and control the amount of fertilizer according to the season and the growth period of hosta. For example, during the flowering period, hosta has a high nutrient demand, and it should be fertilized about once a week.
The above is a brief introduction to the cultivation methods and precautions for hosta. That's all for today's introduction. This article is for reference only, and I hope it can help everyone!
