The soil of Hongyun should be rich in humus, loose and fertile, with good air permeability, good drainage performance and slight acidity (ph5-5.5). The longest use of rotten leaf soil, river sand, a small amount of cake fertilizer, or rotten chicken manure. Of course, in order to save trouble when changing soil, you can buy directly from the flower shop.
The growth life of Hongyun pawn will not be very long, usually 3-4 years old will bloom, gradually wither after flowering, and renew plants after withering. Therefore, the basin should be changed every 1-2 years to ensure adequate nutrient supply in the soil.
Hongyun likes the humid environment, and needs to ensure high air humidity and sufficient basin soil moisture during the growth period. It is advisable to keep the basin soil moist and control the air humidity at 70% - 80%.
The frequency of watering is usually 5-7 days. For some hard leaves which need less water, keep the basin surface dry. For the soft leaf species that need more water, it is better to keep the basin soil moist and keep the surface soil dry. It is necessary to keep the water in the leaf tube frequently, and the water shortage in the leaf tube is easy to cause the plant wilting.
After autumn, the growth of Hongyun will slow down, so water and water spraying should be properly controlled. After entering the dormancy period, it is necessary to control the watering and keep the basin soil slightly damp. If the basin soil is not dry, it will not be watered. If the basin soil is too wet, it will easily rot. Keep the bottom of the barrel moist, but do not give too much water to avoid rot.
In the growing season, fertilizer should be applied once every 10-20 days, and cake fertilizer or fertilizer should be fermented. Nitrogen, phosphorus and potassium are usually used as fertilizer, and the concentration is controlled between 0.1% and 2.3%. When applying fertilizer, try not to put fertilizer in the center of the plant, so as not to cause harm. Fertilization should be stopped in flowering, dormancy and summer.
The growth of hongyundang needs sufficient light, and the light time is controlled at 12-16 hours every day. When the light is sufficient, with high humidity and good ventilation conditions, the growth will be faster and better. The plant will become short, fat and strong, with wide, short and hard leaves and bright and beautiful flowers.
The growth humidity of Hongyun is very important. The appropriate relative humidity is 50% - 75%. If it is higher than 80%, ventilation should be strengthened, otherwise disease or overgrowth may occur. When it is lower than 40%, it is easy to cause the tip of the leaf to wither, so it is necessary to spray water regularly to keep moisture.
The maintenance of Hongyun pawn also depends on magenta. For the varieties like colorful leaves, more light should be put on the windowsill and balcony for maintenance.
The water quality of watering is also very important for Hongyun. It likes to grow in acid soil and requires weak acid water quality. It doesn't like salt, especially calcium and sodium salt.
