Preparation (Top 10 Baking Soda Garden Hacks):
Natural Fungicide Spray
Mix 1 tablespoon baking soda, 1/2 teaspoon liquid soap, and 1 liter of water.
Spray on leaves to prevent or treat powdery mildew and fungal spots.
Sweeten Tomato Flavor
Sprinkle a small amount of baking soda around the base of tomato plants to reduce soil acidity and enhance tomato sweetness.
Weed Killer for Sidewalk Cracks
Pour baking soda directly into cracks where weeds grow. Sweep it in and reapply after rain.
Insect Deterrent
Combine equal parts baking soda and flour, and dust onto cabbage or broccoli to deter caterpillars.
Clean Garden Tools
Use baking soda paste (3 parts baking soda to 1 part water) to scrub rust or grime off tools.
Odor Control in Compost Bin
Sprinkle a layer of baking soda over compost occasionally to reduce odors.
Ant Deterrent
Mix baking soda and sugar in a 1:1 ratio and place in shallow lids where ants are seen. It disrupts their digestion.
Soil pH Testing
Place a tablespoon of moist soil in a cup, add baking soda. If it fizzes, your soil is acidic.
Refresh Birdbaths or Garden Decor
Use a baking soda and water paste to gently scrub and refresh old decor or birdbaths.
Pest-Repelling Plant Wash
Spray a mix of 1 teaspoon baking soda, 1 teaspoon dish soap, and 1 liter of water to repel aphids and spider mites.
Serving and Storage Tips:
Store baking soda in an airtight container in a cool, dry place—moisture can reduce its effectiveness.
Always shake or stir your mixtures before use, especially if stored overnight.
Use clean spray bottles and label each solution clearly to avoid confusion.
Avoid over-application—more isn’t always better. Test on a few leaves first.
Variants:
With Vinegar for Weed Removal: For tough weeds, mix baking soda with vinegar and dish soap—spray directly on leaves (avoid desired plants).
With Neem Oil: Combine baking soda solutions with a few drops of neem oil for a stronger natural pest control spray.
Citrus Boost: Add citrus essential oil to pest deterrent sprays to repel mosquitoes and gnats.
