How to Prevent Aphids in Spring Potted Plants
As the temperature warms up, potted plants enter the peak growing season, and pests like aphids also become active. These tiny insects will suck the sap from the plants, causing the leaves to curl and the new buds to wither. If not treated promptly, it may lead to the death of the plant. Mastering scientific protective methods can ensure the healthy growth of the plants and avoid chemical pesticide pollution.
Physical Barriers for Pest Prevention
Yellow Board Trapping Method
Utilizing the yellow-attraction trait of aphids, choose bright yellow plastic boards coated with eco-friendly adhesive and hang them around the potted plants at a height of 10-15 cm. It is recommended to place 2-3 boards per square meter, and the adhesive layer needs to be replaced every week during the rainy season to ensure optimal trapping results.
Clever Use of Daily Items for Pest Prevention
Alcohol Spray Solution
Dilute 52-degree Baijiu with water in a ratio of 1:3 and add 5ml of vegetable oil to enhance adhesion. Focus on spraying the back of the leaves and tender buds, and after continuous use for 3 days, pause for 1 week to avoid alcohol burning the plant's epidermis.
Detergent Mixture
Dissolve neutral laundry detergent in water at a ratio of 1:800 and add 0.2% urea to make a nutrient insect repellent. Spraying in the evening can extend the duration of the pesticide effect, and the leaves should be rinsed with water 12 hours after treatment.
Plant-Based Natural Protection
Garlic Insect Repellent Preparation
Crush fresh garlic cloves and soak them for 24 hours, then filter the juice and dilute it with water at a ratio of 1:10. This preparation has both preventive and exterminating effects and is recommended to be applied weekly for plants prone to infestation, such as roses and chrysanthemums.
Scallion Protective Liquid
Juice 200g of scallions and mix with 1L of water, adding 3 drops of peppermint essential oil to enhance volatility. Suitable for fragile plants like succulents and green vines, the spray forms a protective film that lasts for 5-7 days.
Comprehensively using physical barriers and biological control, regularly check the condition of the plants, and maintain proper ventilation. When early signs of pest infestation are detected, prioritize using natural preparations to effectively control pests while maintaining the balance of the potted plant ecosystem. It is recommended to rotate different control methods every quarter to prevent pests from developing resistance.
