How to cultivate Artemisia serrata

1. Maintenance methods

1. Temperature: It is not heat-resistant or frost-resistant. When the temperature exceeds 30 degrees, it needs to be placed in a cool place for maintenance. When the temperature is below 10 degrees, it will enter a dormant state and stop growing. The most suitable temperature for its development is between 15 and 20 degrees.

2. Watering: It has a relatively high water content, so it does not require excessive watering. Generally, once or twice a week is enough. Wait until the soil is completely dry before watering. During the rainy season, drainage measures need to be taken to drain excess water, otherwise it will cause root rot. In severe cases, the plant may die due to waterlogging.

3. Fertilization: The seedling stage consumes more nutrients and needs to be fertilized once every three months. The fertilizer should be easily absorbed to promote its growth. Use a compound fertilizer once during the flowering period to effectively promote the development of all aspects of the plant. After the flowers fade, liquid fertilizer needs to be used every two months.

4. Light: It is not resistant to strong light. When exposed to light, it is best to put a sunshade on top of it. It is not necessary in autumn and winter. Normal light is enough. The daily exposure time should be controlled within six hours.

2. Breeding techniques

1. Planting: Planting is usually done in spring, because the climate at this time is stable, the temperature is neither too high nor too low, which is suitable for plant growth and can increase its survival rate. When transplanting, sprinkle bone meal on the soil to serve as base fertilizer, which can promote early growth and development of the plants and produce as soon as possible.

2. Pruning: If the plant grows vigorously but produces few fruits, it needs pruning. Pruning can increase ventilation inside the crown and reduce psyllids, which is very beneficial for its flowering and fruiting.

3. Problem Diagnosis

1. Pathology: The pests that it is often infected with include root rot. To fundamentally solve this problem, you first need to do a good job of garden hygiene and cleaning, and then combine it with proper winter fertilization to effectively prevent and cure root rot. Finally, you need to collect the diseased branches and fallen leaves and destroy them in a centralized manner to avoid reinfection.

2. Yellowing of branches and leaves: Yellowing of branches and leaves of the plant may be caused by excessive light. It is necessary to properly control the strong light exposure and control the light exposure time to five or six hours a day.
