Stop watering immediately and loosen the soil around the plant; the buds might also turn black due to excessive sunlight, so move the plant to a semi-shaded area to grow; it could also be due to the damage caused by aphids, in which case use pesticides such as imidacloprid or prepare pepper water or Sichuan peppercorn water.
The buds of Chinese roses might turn black due to excessive watering, which leads to waterlogging in the potting soil, preventing the roots of the plant from breathing properly, causing them to rot and the buds to turn black.
Treatment: Immediately stop watering the Chinese roses, loosen the surrounding soil, and improve ventilation to accelerate the evaporation of moisture.
When Chinese roses are sprouting new buds, the new buds have low resistance and can easily be sunburned by strong sunlight, causing the buds to turn black and, in severe cases, die completely.
Treatment: Immediately take appropriate shading measures, move the plant to a new location, or build a shade shelter to allow the plant to grow in a semi-shaded environment.
The buds of Chinese roses might also turn black due to pest infestations. Aphids will suck the sap from the tender buds and leaves, causing the new leaves to turn black and twist, and if not treated in time, the entire bud will stop growing.
Treatment: Immediately use the appropriate pesticides for control. You can purchase imidacloprid or prepare pepper water or Sichuan peppercorn water to spray on the plant.
