Aphids can be a significant nuisance in both flower and vegetable gardens, often damaging plants and spreading diseases. Gardening expert Michael Perry recommends using baking soda as an effective and safe insecticide to control these pests. Here are four ways to create your own natural anti-aphid treatments using baking soda:

1. Baking Soda, Olive Oil, and Dishwashing Liquid Mixture
   • Ingredients:
     • ½ teaspoon baking soda
     • 2 cups lukewarm water
     • ⅔ cup olive oil
     • 4 to 5 drops of dishwashing liquid
   • Instructions:
     • Mix all ingredients thoroughly.
     • Transfer the mixture to a spray bottle.
     • Shake the plants gently before spraying to avoid beneficial insects. Directly target aphids.

   • This mixture not only targets aphids but also mites and whiteflies.
2. Pure Baking Soda Application
   • Baking soda alone can repel many insects including ants and slugs. Distribute it around your garden using a flour sifter for even application. It can also be applied directly to pests on the ground or plants, though it should be used sparingly to avoid harm.
3. Baking Soda and Mustard Oil
   • Ingredients:
     • 1 tablespoon baking soda
     • ⅓ cup mustard oil

     • Spray around the garden but avoid direct application on plants.

4. Baking Soda, Neem Oil, and Castile Soap Solution
   • Ingredients:
     • About 4 liters of water
     • 2 tablespoons neem oil
     • 1 tablespoon Castile soap
     • 2 teaspoons baking soda
   • Instructions:
     • Mix all ingredients and pour into a sprayer.
     • Spray the plants with the solution, avoiding sunny days to prevent leaf burn.

Additional Notes:

• Caution: Frequent use of baking soda can negatively affect plants and soil due to its sodium content. It is also crucial to consider the timing of application, ideally during dry, cloudy days to prevent plant dehydration or sunburn.
• Efficacy: Baking soda works by inducing a toxic reaction within insects, leading to their demise.
• Complementary Measures: Planting aphid-repellent plants like marigolds, nasturtiums, and sunflowers can naturally enhance your garden’s resistance to pests.

These methods provide natural and effective solutions to manage aphid infestations, ensuring the health and beauty of your garden.
