Soil

Clean soil is the first priority for potted poinsettia plants, and it should not have any odor. Secondly, it should have good drainage, contain a small amount of soluble salts, and contain necessary elements for the growth of poinsettias. If you are digging soil directly from a community garden, make sure there are no impurities. The soil usually used is mainly peat soil, mixed with perlite, vermiculite, ceramsite, and sawdust. Before planting, the soil should be flattened and exposed to the sun for 30 minutes.

Fertilization

Poinsettias like fertilizer. Fertilize once every 7 to 10 days during the growth period. You can use nitrogen, phosphorus and potassium compound fertilizers. From August until flowering, apply nitrogen and phosphorus liquid fertilizer once every 7 to 10 days. Apply more phosphorus fertilizer when flowering is approaching to ensure large and bright flowers. However, you should not apply too much fertilizer each time, let alone raw fertilizer. Usually fertilize in the evening and water the next morning. In winter, when the light is low, the frequency and concentration of fertilization are halved.

Watering

Poinsettia is sensitive to moisture It is relatively sensitive, uneven watering, dryness or humidity will cause adverse reactions. Excessive watering will cause the leaves to droop or even root rot; insufficient watering will cause the leaves to curl. Therefore, when watering poinsettia, it should be dry and wet. In the early stage of growth (planted seedlings), when the plant is not big, water less; in summer, when the temperature is high and the plant grows vigorously, water more, once every morning and evening, and Depending on weather conditions, spray water on the ground. In spring and autumn, just water once every 1 to 2 days

Light

Poinsettia is a short-day plant. The flower buds will begin to differentiate only if the light time is within 12 hours a day. If you want to bloom normally, Flower buds require more than 15 hours of darkness during differentiation, and light exposure should be avoided during this period (October to March of the following year). In addition, normal maintenance and proper shading at noon in summer are enough.

Notes

Cultivation of Poinsettia The key lies in watering. As long as there is no sudden bad weather, the outdoor environment can fully meet the growth needs of poinsettias. However, improper watering will affect the growth and development of the plant. Ensure that the pot soil is moist but not dry.

Poinsettia is a light-loving flower and can grow vigorously under strong light. However, it cannot tolerate the scorching sun at noon in summer. Proper shading will not hinder its growth.
