The Culture method of Flower poinsettia

Soil

Potted poinsettia soil cleanliness is the most important, there can be no peculiar smell. Secondly, the drainage is good, containing a small amount of soluble salt and the necessary elements to meet the growth of poinsettia. If you dig directly from the garden of the community, make sure there are no impurities. The soil usually selected is peat soil, and perlite, vermiculite, ceramsite and sawdust are mixed. Before planting, the soil is flattened and exposed to the sun for 30 minutes.

Fertilizer application

Poinsettia likes fertilizer, fertilizing once at 7: 10 during the growing period, nitrogen, phosphorus and potassium compound fertilizer can be selected. After August until flowering, nitrogen and phosphorus liquid fertilizer is applied once every 7-10 days, and when it is close to flowering, the application of phosphorus fertilizer can ensure that the flowers are large and colorful. But do not apply too much fertilizer each time, let alone apply raw fertilizer. Fertilization is usually applied in the evening and watered the next morning. The times and concentration of fertilization are halved when the light is low in winter.

Watering

Poinsettia is sensitive to water, uneven watering, dry or wet will cause adverse reactions. If you water too much, the leaves will droop or even rot; if you are not watered enough, the leaves will curl. Therefore, poinsettia should be watered dry and wet. in the early growth stage (seedlings planted), the plant is small and watered less; the summer temperature is high, the plant growth is exuberant, the watering is a little more, water is watered once every morning and evening, and according to the weather conditions, spray water to the ground. You can water once every two days in the spring and autumn season.

Light

Poinsettia is a short-day plant. Flower buds begin to differentiate only after less than 12 hours of light every day. In order to bloom normally, flower bud differentiation requires more than 15 hours of dark time. During this period (from October to March of the following year), lights should be prevented. In addition, normal maintenance, summer noon appropriate shade can be.

Matters needing attention

The key to breeding poinsettia lies in watering, as long as it is not suddenly bad weather, the outdoor environment can fully meet the growth needs of poinsettia. However, improper watering will affect the growth and development of the plant and ensure that the basin soil is wet but not dry.

Poinsettia is a light-loving flower that can grow healthily in strong light, but it is hard to stand the scorching sun at noon in summer. Proper shading will not hinder its growth.
