Valerian cultivation methods and precautions

1. Maintenance methods

1. Soil: The soil for growing valerian should be neutral sandy loam. This kind of soil is fertile and deep, which can meet the needs of growth and can grow better.

2. Water: The soil should be kept moist during the seedling stage. When the plant grows a little bigger and the soil becomes dry, water it appropriately, about once every ten days. When it rains, you can let it enjoy the baptism of rain water, just drain the water in time.

3. Nutrients: Valerian does not require much fertilizer during cultivation, and fertilizing twice a year is enough. Choose compound fertilizer and spread it evenly in the soil. Do not spread it directly on the roots of valerian to avoid burning the roots.

4. Light: Valerian does not like strong light and should be placed in diffuse light. This will allow it to better absorb light and promote vigorous growth.

2. Breeding techniques

1. Pruning: During the maintenance period, regular loosening, weeding and pruning are required to better enable the valerian to grow. If there are yellow and wilted branches and leaves, they should be pruned off appropriately so that they can better absorb nutrients and grow healthily.

2. Reproduction: The main method of reproduction is seed propagation. After the seeds are mature, they are scattered in the soil. Spray water to keep it moisturized, and then it will sprout in about half a month.

3. Problem diagnosis and treatment

1. Mosaic disease: Mosaic disease is common during the growth period of valerian, and this disease will directly affect the growth of the plant. The solution is to prune off the diseased branches and leaves and then spray them with antiviral regulators.

2. Mole cricket: Mole cricket is a common pest of valerian. It is very harmful to valerian. If it is not killed in time, it will affect its growth. It can be solved by spraying it with diluted dichlorodiphenyltrichloroethane.

IV. Other issues

1. How to spend the winter: In winter, it should be moved indoors for maintenance, and the room temperature should be controlled at around 20 to 24 degrees Celsius, and then placed in a place with sufficient light and good ventilation, so as to ensure its safety during the winter.

2. Whether it can be exposed to rain: Valerian can be exposed to rain. The humid air in rainy weather can provide moisture to its branches and leaves, and can also wash away the dust on its branches and leaves, making it look brand new and extraordinarily beautiful.
