Cultivation methods and precautions for potted hosta

1. Maintenance methods

1. Soil: Fertile and water-conserving soil is suitable for growing hosta, and sandy loam is the most appropriate choice. Sandy loam is very suitable for the growth needs of hosta, allowing it to grow better.

2. Water: Hosta likes a humid environment, and frequent watering can make it grow better. But don't let water accumulate in the pot. Just keep the soil slightly moist at ordinary times.

3. Nutrients: There is not much demand for fertilizer during the seedling stage, and it is sufficient to apply fertilizer once every half a month or so. When entering the flowering period, the demand for fertilizer gradually increases. It is sufficient to apply fertilizer once every seven days or so, and you can choose organic fertilizer.

4. Light: It likes to grow in a slightly shaded environment. It is best to give it appropriate diffuse light. It is not suitable for direct sunlight, which will cause damage to the leaves.

2. Breeding techniques

1. Pruning: After cultivating it for a period of time, you should loosen the soil and trim its withered branches and leaves to allow it to be ventilated and light-permeable so that it can grow better.

2. Reproduction: Generally, the method of division is adopted, and the time is between March and April. First, dig out the old plant and dry it in the sun, then apply some charcoal powder on the cut and plant it. Now you can wait for it to sprout new leaves.

3. Problem diagnosis and treatment

1. Spot disease: Spot disease is very harmful to the leaves. In severe cases, it will cause the entire leaf to wither and turn yellow. The prevention and control method is to spray diluted benomyl once a week, and the problem will be solved after about three times.

2. White rot: A common disease of potted hosta is white rot, which will directly damage its roots and cause rot. It can be treated by spraying diluted dichlorodiphenyltrichloroethane.

IV. Other issues

1. How to survive the winter: It is a very cold-resistant plant and will hibernate in winter. At this time, you just need to keep the temperature no lower than five degrees Celsius.

2. Whether it can be exposed to rain: Potted hosta cannot be exposed to rain. On rainy days, they should be placed in a ventilated place indoors to avoid rain. Rainwater stored in the pot will cause its roots to rot, affecting its normal growth.
