1. Pest control(1) Specific reasons: The most likely reason is insect pests, such as mites, red spiders, etc. Sometimes, pests reproduce very quickly, so it is important to take timely measures after discovering them. (2) Solution: There are two solutions. Observe the number of insects. If there are not too many, you can wipe the areas with insects (including the front and back of the leaves) with a wet cloth. Then, rinse the area with plenty of water to remove as many bugs as possible. This method is relatively simple and will not cause any harm. However, if the number is too large, we can only use some pesticides to eliminate them, such as Bichongling, Avermectin, etc. These drugs are effective and work quickly, but they may cause some harm and pollute the surrounding environment. 2. Apply fertilizer appropriately(1) Specific reasons: If there is insufficient nutrition, white spots may also appear on the leaves. This problem may occur in plants grown in soil or water. (2) Solution: Apply appropriate amount of fertilizer. Plants grown in water can use some nutrient solution; plants grown in soil can use some organic fertilizer in moderation. 3. Change water regularly(1) Specific reasons: This situation applies to plants grown in water. If the water is not changed for a long time, the leaves will also have white spots. (2) Solution: Change the water regularly and let the water sit for a few days before replacing it. Also, don't change all the water, leave some of it. |
