2. Improper maintenance and improper maintenance are also one of the reasons for rust spots on Paphiopedilum leaves. The following conditions may cause rust spots on Paphiopedilum leaves: (1) Excessive watering: Paphiopedilum is not resistant to waterlogging, and excessive watering can cause root rot, which in turn causes disease.
(2) Insufficient light: Paphiopedilum requires sufficient scattered light. Insufficient light will lead to slow growth of plants, reduced resistance, and vulnerability to diseases.
(3) Poor air circulation: The growth environment of Paphiophids requires good ventilation, and poor air circulation will lead to rust spots on the leaves.
3. Environmental factors Environmental factors such as temperature, humidity, etc. can also affect the growth of Paphiopedilum, which in turn leads to rust spots on the leaves. The following environmental factors may cause rust spots on the leaves of Paphiopedilum: (1) Too high temperature: Paphiopedilum is not resistant to high temperatures. If the temperature is too high, it will lead to poor plant growth and reduced resistance.
(2) Excessive humidity: Paphiophids prefer humid environments, but too humid can lead to the breeding of diseases. Prevention and control methods of rust spots on Paphiopedilum leaves 1.
