Symptoms: After the victim, the young leaves become pale yellow, and then the old leaves gradually become yellow.

Treatment method: Watering should be controlled immediately, fertilizing, and often loose soil to make the soil ventilation well.

2. Drought and water dehydration

flowers are leaking water or watering for a long time (that is, dry and dry), which affects the absorption of nutrients, and it is also easy to cause the leaves to be dark and lustrous, and the leaves are drooping.

3. Lack of nutrition

Symptoms: Nutritional elements such as ammonia Fertilizer or soil and soil are not exchanged for a long time, and nitrogen in the soil is deficient in nutritional elements, resulting in thin and weak branches and leaves, thin leaves and yellow leaves.

Treatment method: Pour the basin in time to replace the new loose and fertile culture soil to gradually add thin rotten liquid Fertilizer or composite flower Fertilizer.

4. Excessive fat

Excessive Fertilizer will appear thick, and the new leaves will be thick, and they are uneven, and the old leaves will fall off.

Treatment method: Immediately stop fertilization, increase the amount of watering, so that the Fertilizer flows out of the drainage hole from the bottom of the basin, or immediately pour the basin, rinse the soil with water, and then plant it into the pot.

PS: Do not fertilize in winter. You can add some grass and gray to the plant roots to keep warm.

5. High temperature poison

8. Instead of temperature and humidity

In winter, room temperature is too low, and high -temperature flowers are often vulnerable to cold, which will cause leaves to yellow.The room temperature is too high, and the supply of moisture nutrients at the root of the plant is in short, and the leaves will also make the leaves yellow.

When the air is too dry, some flowers that like moisturizing environment, such as spider orchids, orchids, often appear dried or corned leaf margins.

Treatment method: Please pay attention to adjust the room temperature in time, and pay attention to the use of water spraying, plastic film cover and other methods to increase air humidity.

9. Pests and insect pests
