Cultivation methods and precautions of Lilium odoratum

1. Maintenance methods

1. Temperature: The royal lily likes coolness and usually needs to be kept at a temperature between 18 and 24 degrees. Too high a temperature will affect its rooting quality. But we must also keep the plant warm. If the temperature is below fifteen degrees, the plant's buds may fall prematurely and the leaves may turn yellow, greatly reducing its ornamental value.

2. Watering: A lot of water is needed before planting, and irrigation is required almost every day. But after planting, you need to water it in the normal way. Just keep the soil moist, and don't allow water to accumulate to prevent root and leaf rot.

3. Light: Warm and sufficient light needs to be provided. If the light is not enough, the flower buds cannot germinate, and the quality of the flowers will be seriously affected. Strong light will also lead to such a situation, so corresponding measures need to be taken according to the specific situation.

4. Fertilization: If the growth is not good during the growth period, you can add nitrogen fertilizer appropriately to promote the growth rate. About two times will be enough. Foliar fertilizer needs to be applied once a week to ensure that its branches and leaves are green and shiny.

2. Breeding techniques

1. Reproduction: Seeds and bulbs are two important methods. Sowing is generally not recommended because the chance of seeds germinating is very small and the germination cycle is relatively long, taking two years. It is best to use bulbs. The heavier the bulbs, the easier they are to grow and the more flowers they will bloom. You can just bury them directly in the soil.

2. Pruning: The plant of the royal lantern lily is very weak and cannot be pruned too heavily. Just cut off some dead branches and rotten leaves. If it is pruned too heavily, it will be difficult for it to recover and may even die directly.

3. Problem diagnosis and treatment

1. Disease: Gray mold will occur, which will cause gray matter to appear on the branches and leaves, so normal ventilation must be ensured.

2. Pests: Aphids may appear and gnaw on the flower buds of the plant, affecting normal flowering and requiring spraying of dichlorodiphenyltrichloroethane.
