Baking soda isn’t just for baking or cleaning—this humble kitchen staple is a powerful, budget-friendly tool in the garden too. Eco-conscious and incredibly versatile, baking soda can help fight pests, control disease, and even enhance your soil’s health. If you’re looking to give your garden a natural boost, here’s how to make the most of this everyday ingredient.
1. Natural Fungicide for Healthier Plants
Fungal diseases like powdery mildew can quickly spread and damage your plants. To combat this naturally:
- Mix 1 tablespoon of baking soda, 1 teaspoon of liquid dish soap, and 1 gallon of water.
- Spray it on affected leaves once a week to help prevent or reduce fungal outbreaks.
2. Targeted Weed Control
For weeds growing between pavers or in garden paths, baking soda can be a safe alternative to harsh chemicals.
- Simply sprinkle it directly onto weeds in unwanted areas.
- Avoid applying near valuable plants, as it can impact growth.
3. Pest Repellent for Cabbage Worms & Aphids
Baking soda can help deter common pests without harming your crops.
- Combine equal parts baking soda and flour.
- Lightly dust this mixture on leaves where pests are active. It disrupts their feeding and discourages them from returning.
4. Natural Soil pH Adjuster
If your soil is too acidic, baking soda can help bring balance.
- Mix 1 tablespoon of baking soda per gallon of water.
- Pour around the base of plants, but test your soil’s pH first to avoid overcorrecting.
5. Sweeten Tomatoes Naturally
Want juicier, sweeter tomatoes?
- Lightly sprinkle baking soda around the base of tomato plants.
- Gently water it in. This helps reduce soil acidity, enhancing the flavor of your fruit.
6. Compost Booster
Speed up decomposition and reduce odors in your compost pile:
- Add a small amount of baking soda occasionally.
- It helps neutralize excess acidity, creating a more balanced composting environment.
7. Odor Control Around the Garden
To keep unpleasant smells from compost bins or manure storage under control:
- Sprinkle baking soda directly in these areas.
- Reapply as needed to maintain freshness.
8. Rust-Free Garden Tools
Extend the life of your tools with a quick DIY cleaner:
- Mix baking soda with a bit of water to form a paste.
- Scrub tools, rinse well, and dry completely to prevent rust buildup.
9. Boost Seed Germination
Some seeds benefit from a baking soda soak before planting:
- Dissolve 1 teaspoon of baking soda in 2 cups of water.
- Soak seeds for 6–12 hours, then rinse before planting to encourage faster sprouting.
10. Natural Ant Barrier
Keep ants away from plants and garden beds:
- Sprinkle baking soda along ant trails or around plant bases.
- For extra potency, mix with sugar to attract ants—once consumed, it deters them from returning.
