Xiandanhua grows in the sandy soil with rich soil, loose soil and good drainage. Potting can choose culture soil, peat soil, coarse sand mixed with a small amount of organic fertilizer, pH control between 5-5.5.
Dandelion is resistant to dampness. At the early stage of growth, sufficient water is needed to keep the basin soil moist, which is conducive to shoot germination and leaf growth. Do not over water, soil water, will cause some root rot, affect growth and flowering. If the water supply is insufficient, the phenomenon of falling leaves will occur.
The growth of Xiandan flower needs sufficient sunshine, especially the growth of stem and leaf. Sufficient sunshine can ensure the leaves are green and shiny, which is conducive to the formation of inflorescence and orderly flowering. If it grows in a half shade environment, the leaves turn yellow, the flowers are light, and the flowers are sparse. But in summer, when the light is strong, it is moderately shaded. It can prolong the flowering period.
The suitable growth temperature of xiandanhua is 15 ~ 25 ℃, the temperature is controlled at 24 ~ 30 ℃ in March ~ September, the debt is controlled at 13 ~ 18 ℃ in March ~ next year, and the temperature in winter is above 0 ℃, so it can survive the winter safely. In a word, the adaptability of xiandanhua to temperature is very strong, it can withstand high temperature above 32 ℃, and still can continue to grow.
In the growth period, fertilizer is applied once every half a month, mainly organic compound fertilizer, supplemented by ferrous sulfate and hooves. Before application, the fertilizer is mixed with water and used after ripening and fermentation.
In the growing period, the liquid fertilizer of 1:1:1:2:3 of nitrogen, phosphorus, potassium and horseshoe was applied once every half a month.
Pruning now spring, the plant just moved to the outdoor, to carry out appropriate thinning, to ensure ventilation and light. In addition, in the flowering stage, the heart can be properly removed to promote the pregnancy and flowering.
The soil for the growth of xiandanhua needs to be kept slightly acidic. When watering, pay attention not to water alkaline water, and apply a small amount of ferrous sulfate every month.
The potted elixir in the South can be placed outdoors for maintenance in winter. In case of cold current, it can be covered with plastic film for heat preservation. The northern area needs to be moved to indoor maintenance.
