Raising poinsettias requires sufficient light, and controlling the light time can advance or delay the flowering period. The plant likes warmth and cannot be lower than 15℃ in winter, otherwise it needs to be bagged for insulation. The soil should be loose and fertile, with good drainage. Daily watering should be appropriate, keeping it moist but without stagnant water. Fertilization is mainly done during the growing period, once every 10-15 days. In addition, it must be topping and pruning to promote the development of side branches and improve the ornamental quality.

1. Light: The growth of poinsettia requires sufficient light. It has strong phototropism and needs to be exposed to the sun all year round. If there is insufficient light, the plants will grow easily and flowering will be affected. As a short-day plant, the flowering period can be advanced or delayed by controlling the light time. If it is guaranteed to have 8 hours of light every day, it will bloom in 40 days.

2. Temperature: Poinsettia likes warm climate and is cold resistant Relatively poor. Be sure to keep warm in winter and keep the room temperature between 15-20°C. If it is lower than 15℃, it will affect the discoloration of the bracts and is not conducive to flower bud differentiation. You can cover the upper part of the plant with a plastic bag to keep it warm, but it should be removed regularly for ventilation.

3. Soil: Poinsettia is suitable for growing in loose and fertile soil. Good drainage can prevent the roots from being flooded and reduce the possibility of root rot. If you need to prepare potting soil, you can mix garden soil, humus soil, leaf humus soil and cake fertilizer to form a substrate in a ratio of 3:3:3:1, and add a small amount of slag.

4. Watering: Poinsettia is not very drought-tolerant. , and are also afraid of getting wet, so watering should be done according to the climate and growth conditions. The soil should be kept moist during the growing period, but not waterlogged. Watering should be reduced during the flowering period. Too much water will cause the flowers to fall. Watering should be even, otherwise the leaves will turn yellow and fall off, and the branches will grow unevenly.

5. Fertilization: Poinsettias need to be fertilized when they are potted. Generally, organic fertilizer or water chestnut slices are used. During the growth period, liquid fertilizer should be tried every 10-15 days. You can dilute the decomposed sesame paste residue 5 times before use. In autumn, compound fertilizer should be added and applied once a week for a month to promote the differentiation of flower buds.

6. Pruning: Three weeks after the poinsettia is planted, it is necessary to Top it off to encourage the growth of side branches. During the dormant period, diseased and weak branches should be pruned. If the plant is repotted, the roots can also be pruned appropriately. In autumn, pruning is required to make the plant smaller and improve its ornamental value.
