Cultivation methods and precautions of Xiandanhua

Breeding environment

soil

The iris grows in fertile, loose and well-drained sandy soil. For potted plants, you can choose culture soil, peat soil, coarse sand mixed with a small amount of organic fertilizer, and control the pH between 5-5.5 .

Watering

The iris can tolerate moisture but is afraid of dryness. Sufficient water is needed in the early stages of growth to keep the soil moist, which is conducive to the germination of branches and leaf growth. Avoid excessive watering, as waterlogging in the soil will cause partial root rot and affect growth and flowering. If the water supply is insufficient, leaves will fall.

Sunlight

The growth of the iris requires sufficient sunlight, especially the growth of the stems and leaves. Sufficient sunlight can ensure that the leaves are tender green and shiny, which is conducive to the formation of inflorescences and neat flowering. If grown in a semi-shady environment, the leaves will turn yellow, the flowers will be light in color, and the flowers will bloom sparsely. But provide moderate shade when the sun is strong in summer. Can extend the flowering period.

temperature

The suitable growth temperature for Ixora is 15~25 ℃. From March to September , the temperature should be controlled at 24~30 ℃. From September to March of the following year, the temperature should be controlled at 13~18 ℃. The winter temperature should be above 0 ℃, and it can safely overwinter. In short, the Ixora has a strong adaptability to temperature and can withstand temperatures above 32 °C and still continue to grow.

Fertilization

Fertilize once every half a month during the growing season, mainly with organic compound fertilizer, supplemented by ferrous sulfate and hoof slices. Before application, mix the fertilizer with water and use it after decomposition and fermentation.

During the growing season, apply liquid fertilizer once every half a month using a mixture of nitrogen, phosphorus, potassium, and horseshoe slices in a ratio of 1:1:1:2:3 and add water after decomposition and fermentation.

prune

Pruning: Now in spring, when the plants have just been moved outdoors, appropriate pruning should be carried out to ensure ventilation and light. In addition, during the flowering period, you can pinch the tips of the plants appropriately to promote bud formation and flowering.

Precautions

The soil for the growth of the iris needs to be kept slightly acidic. Be careful not to use alkaline water when watering. A small amount of ferrous sulfate can be applied every month.

Potted elixirs in the south can be placed outdoors for maintenance in winter. If there is a cold wave, you can cover the plants with plastic film to keep them warm. In northern regions, it needs to be moved indoors for maintenance.
