How to grow gentian

1. Maintenance methods

1. Temperature: Gentiana prefers a cool growing environment, so most of them are generally planted in the north. It has a high cold resistance and can withstand temperatures as low as minus 25 degrees Celsius, so it can completely spend the winter outdoors. However, it should be noted that the temperature in summer should not be too high, otherwise wilting and dehydration will occur.

2. Watering: Gentian likes moist soil and needs to be watered from time to time. The specific amount of watering should be determined according to the dryness and wetness of the soil. In summer, the amount of watering can be increased, but it is best not to allow water to accumulate.

3. Light: Gentiana likes sufficient warm light, which can make its flowers more colorful and the plant grow better. At the same time, more attention should be paid to light during the seedling stage of the plant. Sufficiently warm sunlight can make the seedlings stronger and grow into more ideal plants.

4. Fertilization: Gentiana has a relatively high demand for fertilizer. The soil needs to be kept fertile, and sufficient fertilizer helps it bloom. Before planting, some base fertilizer needs to be applied, mainly animal manure. After that, during the breeding period, you can also apply organic fertilizer and combine it with practical compound fertilizer.

2. Breeding techniques

1. Reproduction: division and sowing are two important methods of reproduction. Division can be done in early April every year. Simply dig out the roots of the seeds, divide them into several parts, and then replant them. Sowing is carried out in spring and autumn. When sowing, you should pay attention to the spacing. The distance should not be too close. If sowing is done in autumn, it will germinate in the spring of the following year.

2. Pruning: Gentiana is generally planted in large areas, so it does not require much pruning. During the cultivation process, some yellowing and withered branches and leaves will appear, which can be directly picked off by hand.

3. Problem diagnosis and treatment

1. Disease: Leaf spot may occur, which will affect the final yield, so the diseased branches and leaves need to be cut off in advance. Afterwards, the pesticides should also be diluted for prevention and control.

2. Pests: Aphids may occur, use DDT solution to control them as early as possible.
