Cardinal corals are native to the West Indies of Central America. Sex is warm, suitable for a sunny, not too strong and well ventilated place. If the temperature is too high, semi negative conditions can also be adapted. It is required that the cultivated soil be loose, fertile and well drained.
There are species of red sparrow corals, class leaf red sparrow corals and curly leaf corals. The same genus of white sparrow corals is similar to the red sparrow corals, but the midvein of the leaves is not prominent, the leaves are thinner, and there are irregular white patches in the green.
Red sparrow coral can be used as medicine. It can clear away heat and detoxification, dissipate blood stasis and swelling, stop bleeding and generate muscle. External use for injuries, fractures, bleeding, furuncles and sores, keratophthalmitis
The red sparrow corals are warm and drought tolerant, with a suitable temperature of 23 ℃ to 30 ℃. After freezing, leaves will turn white and fall off. It is shade resistant, and half shade of the cultivation site is conducive to flowering, and the leaf color is more beautiful. It is afraid of wind, suitable for growing in dry and windless environment. The cultivated soil should be sandy loam with good drainage and aeration. Turn the basin once a year or every other year. If the branches are too long, they should be cut short or supported by pillars. Branches can be pruned to promote more branches.
During the growth period, the amount of water should be controlled, generally after the soil is dry. Organic fertilizer or a small amount of nitrogen, phosphorus and potassium can be used for fertilization. In winter, we should reduce the supply of fertilizer and water. The red sparrow coral is propagated by cutting. Cuttage can be used all year round in greenhouse, but it is better in warm season. Take the stem tip or tender stem and cut it into 10 cm long stem segments for cuttings. The cuttings shall be dried first, or the cut shall be inserted into the dry ash and dry soil to make the pulp be absorbed, and then the cuttings shall be cut. The medium can be yellow sand, perlite or husk ash. After rooting, the cuttings can be transplanted into the pot.
First, light: the requirements for light are not strict. Under strong light, the leaves are reddish, and under half shade, they are green. But don't let the strong sunlight direct in summer, also don't put in too dark place indoors.
Second, temperature: the red sparrow coral likes to be warm, which is suitable for growth in spring, summer and autumn. In winter, when the temperature is lower than about 13 ℃, the leaves will turn white and fall off.
Third, watering: the red sparrow coral is a succulent plant with strong drought resistance. In the growing season, water it every time when the pot soil is half dry. In winter, when the basin soil is dry, water it a little more. Too much water will cause mildew, more serious stem base rot.
Fourth, fertilization: in the growth period can apply compound fertilizer to the plant once a month.
Fifth, basin soil: the cardinal coral is suitable to use the sandy loam with good drainage, loose and fertile
Sixth, propagation: the redfinch coral can be cutted with 5-15cm long stem. Like other Euphorbiaceae plants, the red sparrow coral will flow out white milk once it is cut. If the cut is immersed in water, it can be stopped. The cuttings should be dried in the shade for one day. Let the incision dry and then insert them on the substrate.
