This article will take you deep into the causes and preventive methods of white dots on succulents, helping you to cultivate healthy and beautiful plants.
Causes of Small White Dots on Succulents1. Disease Infection: Small white dots on succulents may be caused by pathogenic infections, such as powdery mildew, gray mold, etc., which lead to white spots on the leaves and can cause leaf wilt and shedding in severe cases.
2. Pest Damage: Pest damage is also one of the reasons for the appearance of small white dots on succulent leaves, such as aphids, scale insects, etc., which extract nutrients from the plant, leading to spotted leaves.
3. Environmental Factors: Succulents are sensitive to environmental changes, and inappropriate environmental factors such as lighting, temperature, and humidity can also cause white spots on leaves.
4. Improper Care: Issues like excessive watering, improper fertilization, and poor soil aeration can also lead to white spots on succulent leaves.
Methods to Prevent and Treat Small White Dots on Succulents1. Disease Control: When small white dots appear on succulent leaves, isolate the affected plants promptly to prevent the spread of the disease. Use a 75% wettable powder of chlorothalonil at a concentration of 1000 times to spray the leaves, spraying every 7-10 days for 2-3 consecutive times.
2. Pest Control: For pest control, spray the leaves with pesticides like imidacloprid or acetamiprid, ensuring even coverage to prevent pests from developing resistance.
3. Improve Environment: Maintain good ventilation and lighting conditions, and adjust temperature and humidity appropriately to create a suitable environment for succulents to grow.
4. Optimize Care: Water reasonably to avoid积水, fertilize regularly, maintain soil aeration, and observe the growth of succulents, dealing with issues promptly.
Preventive Measures for Small White Dots on Succulents1. Choose Healthy Plants: When purchasing succulents, choose plants free of diseases and pests that are growing vigorously.
