1、 How to make Poinsettia blossom

1. Temperature control: it likes warm environment and has poor cold resistance. If it wants to blossom, it should be moved indoors after cooling down every autumn. In winter, the indoor temperature should be kept between 15 and 20 degrees. At this time, the plant is in the stage of flower bud differentiation. If the temperature is lower than 15 ℃, the flowers will develop poorly and affect the later flowering

2. Sufficient fertilizer: it naturally consumes more nutrients for flowering, so it should be fertilized and supplemented in time. In the growing and flowering season, the decomposed liquid fertilizer should be applied every half a month. After autumn, compound fertilizer should be applied once a week for three or four consecutive times. Such management can promote flower bud differentiation and bract discoloration

3. Timely pruning: in the growth stage, if sick and weak branches are found, they should be cut off in time to reduce nutrient consumption. When the branches grow to 20-30 cm, they should also be shaped into bends to make the plant shape shorter and the flower heads more orderly, so as to help flowering and improve its ornamental ability

2、 How to deal with the flowers

Poinsettia should be trimmed after flowering, and the main and side branches should be shortened. If it is allowed to grow at this time, there will be bare branches, and the whole plant shape will be affected, so it will lose its ornamental. After pruning, place it in a dark place. Don't expose to the sun, and don't rush to water. Don't let the wound get wet. After careful maintenance for a period of time, it can be recovered slowly
