It is usually sixty centimeters to three meters high, and its dark green leaves are about seven to sixteen centimeters long. The top leaves are fiery red, red, or white, so they are often mistaken for flowers, and the flowers are in the middle of the leaf bundle. The flowering period can last from December to February of the following year.

Use perlite, peat, vermiculite, river sand and coconut bran. : 1: 3: Add a small amount of earthworm feces after mixing in proportion. Add an appropriate amount of phosphorus and potassium fertilizer as a base fertilizer when potting to increase soil fertility.

temperature

Poinsettia likes to be warm and cold, and the normal temperature can grow normally from 15 to 20, so in September, it should be moved indoors and the indoor ventilation should be enhanced to allow the plants to quickly adapt to the indoor environment To facilitate flower bud differentiation. It should be noted that the indoor temperature cannot be lower than 15 degrees to avoid poor flower and leaf development.

illumination

Poinsettia is a short-day plant. Generally, light given within 12 hours per day can promote the differentiation of flower buds, so try to put it in a lighted place in spring, autumn and winter, and shade it properly in summer to avoid light. If it is too strong, it will evaporate the leaves and affect flowering. Of course, if you want to flower early or late, you can give 8 to 9 hours of light every day, and you can bloom in 40 days.

Watering

The water requirement is not high. Generally, the potted soil 1 / {{{{{2}}}} can be poured with an appropriate amount of water when it is dry. Avoid pouring "half waist water".

When watering, do not over or under to avoid drooping leaves. The amount of watering can be determined according to the degree of dryness and wetness of the basin soil. Watering should be done in the morning during the growing season, and the water temperature should be close to the temperature. In winter, try to water around noon to help plants absorb water better.
