9. Aspirin for Plant Immunity
Aspirin, or acetylsalicylic acid, can boost plant immunity by triggering a defense response similar to how it works in humans. To use aspirin in your garden, dissolve one aspirin tablet in a gallon of water and spray it on your plants every three weeks. This can help improve their resistance to diseases and stress.
Research has shown that aspirin can also enhance plant growth and increase yields in crops like tomatoes and peppers. However, it’s important to use it sparingly, as excessive use can have adverse effects.
10. Milk as a Natural Fungicide
Milk is a natural fungicide that can help control powdery mildew and other fungal diseases. To create a milk spray, mix one part milk with two parts water and apply it to the affected plants every 10 to 14 days. The proteins in milk act as an antiseptic, helping to kill fungal spores and prevent their spread.
This method is particularly effective for cucumbers, squash, and other plants susceptible to powdery mildew. It’s a safe and eco-friendly alternative to chemical fungicides.
11. Hydrogen Peroxide for Root Health
Hydrogen peroxide is a powerful oxidizer that can improve root health by increasing oxygen levels in the soil. To use hydrogen peroxide in your garden, mix one part 3% hydrogen peroxide with two parts water and water your plants with this solution once a week. This can help prevent root rot and promote healthy root development.

Hydrogen peroxide can also be used to disinfect seeds before planting. Soak seeds in a solution of one part hydrogen peroxide to ten parts water for 30 minutes to reduce the risk of fungal infections and improve germination rates.
