1. Reasons1. The sunlight received by the plant is too strong. Under scorching conditions, the leaves of the plant may be sunburned, causing rust spots to grow on the leaves of the plant. 2. If the plant is infected with pests and diseases due to improper maintenance, the plant will also grow rust spots on the leaves due to the damage. The longer the plant is infected, the larger the area of the leaves infected will be. II. Remedial Measures1. If the rust spots are caused by strong sunlight, you can remove the rusty leaves in time and then shade the plants. However, the plant cannot be kept in a dark place all the time. It should be allowed to receive some scattered light, otherwise it will lead to malnutrition of the plant. 2. If the plant is infected with pests and diseases, in order to prevent the disease from spreading to other leaves, the diseased leaves should be pruned off quickly, the pruned leaves should be burned, and then the leaves should be sterilized with pesticides or disinfectants, and then the plants should be placed in a ventilated place to allow the plants to recover. |
