How to Use Baking Soda in the Garden: A Natural Ally for Your Plants

🔹 Why Baking Soda Works for Plants

Baking soda, or sodium bicarbonate, has several properties that make it useful in the garden:

• Fights fungal infections: It can prevent or slow down the growth of powdery mildew and other fungal diseases.
• Balances soil pH: A mild application can slightly reduce soil acidity, helping some plants thrive.
• Natural pest deterrent: While it doesn’t replace pesticides entirely, it can discourage some garden pests.
• Eco-friendly: It’s safe for the environment, pets, and children when used correctly.

🍃 Ways to Use Baking Soda in the Garden

1. Powdery Mildew Treatment

Powdery mildew is a common fungal disease affecting roses, cucumbers, squash, and many ornamental plants. Baking soda can help:

Recipe:

• 1 tablespoon baking soda
• 1 gallon water
• Optional: 1 teaspoon mild liquid soap (to help the solution stick)

Instructions:

1. Mix all ingredients in a spray bottle.
2. Spray affected leaves thoroughly, including the undersides.
3. Repeat every 7–14 days until the fungus is gone.

2. Soil pH Adjustment

Some plants, like tomatoes and peppers, prefer slightly less acidic soil. Sprinkle 1 teaspoon of baking soda per square foot of soil and water it in lightly. This can gently raise the pH, making nutrients more available.

3. Tomato and Vegetable Plant Spray

Baking soda spray can reduce fungal infections and help your vegetables grow healthier. Mix the same recipe above and apply every couple of weeks as a preventative measure.

4. Deterring Pests

While it won’t kill pests, baking soda sprinkled lightly around the base of plants can deter ants, slugs, and other unwanted visitors. Combine with diatomaceous earth for better pest control.
