1, auxiliary lighting
Rose is a common flower plant, which likes light. During its growth, it needs sufficient light to ensure the growth of flowers and leaves. If the light is insufficient, the leaves of Chinese rose will droop and become soft. Rose is short of light, so it can be moved to an outdoor environment with good light for maintenance. After a period of maintenance, the leaves of Chinese rose will gradually recover.
Step 2 control the temperature
Rose likes temperature and is suitable for growing in a warm, ventilated and sunny environment. The suitable temperature for the growth of Chinese rose is between15 and 26 degrees, and the temperature in winter is above 5 degrees. The environmental temperature for the growth of Chinese rose is too high. When the temperature is above 30 degrees, the leaves will soften and the flowers will droop. If the temperature is high, it needs to be moved to a suitable position.
3. Rational fertilization
Chinese rose flowers have a high demand for fertilizer. When they bloom, they need enough fertilizer to make them bloom, but they can't be over-fertilized. Excessive fertilization of Chinese rose will burn the root system, affect the normal opening of flowers and cause the flowers to droop. If there are too many nutrients or the concentration of fertilizer is too high, water the roses in time, which can dilute the fertility.
4, timely drainage
Rose needs water to bloom, but it is not waterlogged, so it needs proper watering. If there is too much water, the roots of roses will rot after the water accumulates in the basin bottom, making the flowers droop or fall off. If the pot soil is too wet, loosen the soil for the rose in time, put the flowerpot in a ventilated place to accelerate the evaporation of water, and then water it properly later.
5, spraying prevention and control
Rose is prone to diseases and insect pests during its growth, such as black spot, rust, aphid, scale insect or red spider. When roses are damaged by diseases and insect pests, the flower bones will wither. It is necessary to cut off and burn the diseased leaves, flowers and branches of roses, and then spray the roses with relevant chemicals to remove pests and diseases.
