Cultivation methods and precautions of Ligustrum lucidum

1. Maintenance methods

1. Soil: Ligustrum lucidum does not have high requirements for soil, ordinary clay soil is enough. Loose and breathable soil can better promote its absorption of nutrients and make it grow more vigorously.

2. Water: When replenishing water during the breeding period, the amount of water must be controlled. The land should be moist and there should be no stagnant water. The soil cannot be too dry, otherwise its growth will be stunted.

3. Nutrients: Before planting, you should evenly sprinkle a layer of compound fertilizer on the soil, and then turn it over and stir it so that the fertilizer and soil can be evenly mixed, so that it can better absorb nutrients.

4. Light: Adequate light can make the branches and leaves thick and full, and it also has strong shade tolerance. However, it is not suitable for direct exposure to strong light, as direct exposure will damage the branches and leaves and affect normal growth.

2. Breeding techniques

1. Pruning: After growing for a period of time, the top branches and leaves will wilt and turn yellow, and the new branches below will be weak due to lack of ventilation and light. At this time, they need to be properly pruned to allow ventilation and light to pass through, and the shape will be rounded for better growth.

2. Reproduction: Just use the cutting propagation method. In the spring, cut off strong and thicker branches, insert them into soil with sufficient nutrients, and then spray some water to keep them moist.

3. Problem diagnosis and treatment

1. Ligustrum looper: Ligustrum looper is a common pest of Ligustrum lucidum. Improper prevention and control will cause serious damage to its branches and leaves. Use diluted diflubenzuron to spray it or directly capture and kill it.

2. Nocturnal brown spot: This disease will attack the leaves of the plant, causing black mold to appear around the leaves and then they will dry up and fall off. You can just dilute thiophanate-methyl and spray it, or you can use potassium permanganate to sterilize the soil before planting to take preventive measures in advance.

IV. Other issues

1. How to spend the winter: The temperature will be relatively low during the winter, so it needs to be moved indoors for maintenance. It is best to place it in a light-transmitting place. The temperature should not be lower than 5°C to avoid frostbite to the plant.

2. Can it be exposed to rain: It can be exposed to rain, because it is a moisture-loving plant. Rainwater can wash away the dust on its branches and leaves. It can be refreshed after being baptized by rain, but attention should also be paid to drainage.
