1、 Leaf spot
Leaf spot disease is the most common disease in the disease cycle of Cymbidium. Cymbidium with leaf spot disease will seriously affect the leaves of plants, make them turn yellow gradually, and finally lead to wilt. Sometimes it will lead to abnormal development of leaves, or no flowering, etc. Reduce the normal growth of plants and the beauty of plants p>
Cause
When this condition occurs, it indicates that the plant growth environment is not suitable. It may be caused by inappropriate fertilizer and water p>
Solutions
So how to treat the disease? We can fertilize the plants on time and in quantity. The specific time is once every three months p>
Light: the demand for light is great. Except in summer, the light needs to be strengthened in other seasons. If the sunlight is insufficient, the leaves can be too thin and even threaten the health of plants p>
Temperature: it is about 20 degrees during the day and 10 degrees at night. The sun can be properly shielded in summer p>
Watering: there is no need to water frequently. Watering is only necessary when the topsoil is dry. Too much water will cause water to be unable to be eliminated, and long-term soaking of the root in water will lead to plant decay. When the soil in the basin has no water, it will affect the normal growth and development of leaves and even flowering. Cymbidium has a short dormancy in winter. During this period, we should reduce watering. If the air near the plant is too dry, spray water with the help of a tool watering can, several times a day p>
2、 Diseases caused by freezing injury
Tiger ear orchid likes strong light, high temperature and well ventilated environment. Therefore, be sure to remember not to place it in a cold and humid environment. Once the air is too cold, or outside in winter, it will cause freezing injury. After low temperature freezing injury, the leaves of Cymbidium will affect the normal function of plants, and then gradually rot, wither, fall, and finally die p>
Solution
When the plant shows signs, we can put the plant on the balcony or the window sill with sufficient light to provide sufficient sunshine for the plant. If we want the plant to thrive, we can also build an insulation shed for the potted plant to maintain a reasonable temperature for a long time p>
