What Are the Benefits of Baking Soda for Trees?
Baking soda isn’t just for baking—it’s also a handy tool for maintaining the health of your fruit trees. Here’s why and how to use it effectively:

1. Fight Against Diseases:
- Baking soda can prevent and treat fungal diseases like late blight and powdery mildew.
- Use it preventatively by diluting it in water and watering the plant, or curatively by mixing it with water and black soap and spraying the affected plant.
2. Regulate pH:
- Baking soda’s alkalizing properties can help raise the pH of acidic soil, which can improve nutrient absorption for fruit trees.
- Sprinkle it around the tree or mix it with water and apply it to the garden soil.
3. Homemade Natural Insecticide:
- Baking soda can have a mild insecticidal effect, particularly against pests like aphids and mites.
- Create a solution with water, baking soda, and neem oil, then spray it directly on the leaves and fruit of your trees.
Precautions to Take:
- While baking soda is natural, it should be used with caution to avoid harming the soil’s microflora and fauna.
- Apply it every two weeks from early spring to late summer, avoiding hot weather or direct sunlight to prevent leaf burn.
- Apply in the early morning or late evening to minimize the risk of leaf damage.
By using baking soda wisely, you can effectively manage diseases and pests in your fruit trees while minimizing environmental impact.
