“Baking Soda in the Garden: 10 Genius Hacks Every Gardener Should Know”

  • Baking soda (100% sodium bicarbonate)

  • Water

  • Liquid dish soap (biodegradable preferred)

  • White vinegar (optional)

  • Spray bottle

  • Small bowl

  • Measuring spoons

  • Soft cloth or sponge

  • Garden gloves


Preparation (Top 10 Baking Soda Garden Hacks):

  1. 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.

  2. Sweeten Tomato Flavor

    • Sprinkle a small amount of baking soda around the base of tomato plants to reduce soil acidity and enhance tomato sweetness.

  3. Weed Killer for Sidewalk Cracks

    • Pour baking soda directly into cracks where weeds grow. Sweep it in and reapply after rain.

  4. Insect Deterrent

    • Combine equal parts baking soda and flour, and dust onto cabbage or broccoli to deter caterpillars.

  5. Clean Garden Tools

    • Use baking soda paste (3 parts baking soda to 1 part water) to scrub rust or grime off tools.

  6. Odor Control in Compost Bin

    • Sprinkle a layer of baking soda over compost occasionally to reduce odors.

  7. 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.

  8. Soil pH Testing

    • Place a tablespoon of moist soil in a cup, add baking soda. If it fizzes, your soil is acidic.

  9. Refresh Birdbaths or Garden Decor

    • Use a baking soda and water paste to gently scrub and refresh old decor or birdbaths.

  10. 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.
