14 Nifty Uses Of Baking Soda In The Garden
1. Natural Fungicide For Powdery Mildew
Powdery mildew is a common garden problem. Baking soda helps slow its spread by changing the leaf surface pH.
How to use:
Mix 1 tablespoon baking soda, 1 teaspoon liquid soap, and 1 gallon of water. Spray affected leaves weekly.
2. Pest Deterrent For Aphids And Ants
Soft-bodied insects dislike baking soda’s texture and alkalinity.
Tip:
Sprinkle lightly around plant bases or mix with water for a gentle spray.
3. Weed Control For Cracks And Pathways
Baking soda works well against weeds growing in sidewalk cracks or garden edges.
Important:
Avoid using it directly in garden beds—it can affect soil balance.
4. Sweeten Tomatoes Naturally
If your tomatoes taste overly acidic, baking soda can help.
How:
Sprinkle a small amount on soil near the base (not on leaves). It reduces soil acidity slightly, improving flavor.
5. Deodorize Compost Bins
Compost can get smelly, especially in warm weather.
Solution:
Add a light sprinkle of baking soda to neutralize odors without harming decomposition.
6. Clean Garden Tools Safely
Rusty or dirty tools spread disease between plants.
Method:
Create a paste of baking soda and water. Scrub tools clean and rinse thoroughly.
7. Repel Slugs And Snails
Slugs dislike abrasive surfaces.
Use:
Sprinkle a thin barrier around pots or raised beds (reapply after rain).
8. Neutralize Acidic Soil (Small Areas Only)
Some plants struggle in overly acidic soil.
Note:
Use sparingly and test soil first. Baking soda is best for spot correction, not large areas.
9. Freshen Up Garden Gloves And Shoes
Gardening gear can trap moisture and odor.
Tip:
Sprinkle baking soda inside gloves or boots overnight, then shake out.
10. Control Cabbage Worms
Cabbage worms dislike baking soda when combined with flour.
How:
Mix equal parts baking soda and flour. Dust lightly on affected plants.
11. Improve Flower Blooms
Certain flowering plants respond well to slight pH adjustments.
Best for:
Begonias, hydrangeas (pink shades), and geraniums—use cautiously.
12. Clean Birdbaths And Pots
Birdbaths and clay pots can develop algae and residue.
Cleaning mix:
Baking soda + water + stiff brush. Rinse well before refilling.
13. Reduce Odors In Greenhouses
Warm, enclosed spaces can trap plant and soil smells.
Fix:
Place small open containers of baking soda around the greenhouse.
14. Test Soil Acidity At Home
A quick DIY test gives insight into your soil’s pH.
How:
Add baking soda to moist soil. If it fizzes, your soil is acidic.
