Washing powder can prevent flower pests
Washing powder can be an effective, natural method for controlling pests on most potted plants. By spraying a 1000-times diluted detergent solution onto the leaves of your flowers, you can protect them from red spider infestations for approximately two weeks. This method is especially useful for dealing with pests on perennial herbs and woody plants. For more persistent insect problems, applying the same 1000-times diluted solution every 3 to 4 days for 2 to 3 consecutive times can significantly reduce pest populations.
Additionally, pouring the diluted detergent solution around the base of the plant can help prevent root and bulb nematode damage. However, it's important to note that long-term use of washing powder as an insecticide may increase the alkalinity of the soil and potting mix, which could negatively affect the health and growth of your plants over time.
To counteract this, it’s recommended to occasionally apply acidic fertilizers or adjust the pH of the soil. Regularly replacing the soil in your pots can also help prevent the buildup of alkaline substances. Always monitor your plants closely and consider using alternative pest control methods to avoid over-reliance on detergents. With proper care and balance, you can keep your indoor and outdoor plants healthy while maintaining a safe and eco-friendly environment.
