Baking Soda Is the Gardener’s Best Friend: Here Are 10 Smart Uses in the Garden
Baking soda is a true multitasker in the kitchen, but did you know it’s also incredibly useful in the garden? This humble household item can help with everything from improving soil health to repelling pests. Whether you’re an experienced gardener or just starting, baking soda is an affordable and eco-friendly tool that can help your garden thrive.
In this article, we’ll explore 10 clever ways to use baking soda in your garden to enhance plant growth, fight pests, and keep things growing beautifully.
1. Soil pH Adjustment
One of the most important factors for healthy plants is the pH level of your soil. Some plants prefer acidic soil, while others thrive in neutral or alkaline conditions. If you have alkaline soil (which is common in many regions), baking soda can help lower the pH, making it more acidic and ideal for acid-loving plants like tomatoes, blueberries, and azaleas.
How to use it:
- Mix 1 tablespoon of baking soda into a gallon of water.
- Apply the solution to the soil around the base of the plants you wish to adjust the pH for.
- Repeat as needed, depending on how your plants respond.
2. Fungus Control
Fungi can wreak havoc in your garden, especially during humid conditions. Baking soda has antifungal properties that can help combat mildew, mold, and other fungal issues on plants. It works by altering the pH of the plant’s surface, making it less hospitable to fungal growth.
How to use it:
- Mix 1 tablespoon of baking soda with 1 gallon of water.
- Add a few drops of liquid dish soap to help the mixture stick to the plants.
- Spray it directly on the affected leaves or areas where fungus is present.
3. Natural Pest Repellent
If you’re looking for a non-toxic way to keep bugs away, baking soda is a great option. It can deter ants, roaches, and even slugs. Sprinkling a small amount around the base of plants can help create a barrier that pests avoid.
How to use it:
- Simply sprinkle a light layer of baking soda around the perimeter of plants or along known pest pathways.
- For slugs, create a small line of baking soda around your plants, as the abrasive texture can deter them.
4. Clean Garden Tools
Garden tools can become coated with dirt, sap, and plant residue over time. Baking soda is an excellent natural scrubber for cleaning your tools and keeping them rust-free.
How to use it:
- Make a paste by mixing baking soda and water.
- Use a scrub brush or sponge to clean tools, removing dirt and buildup.
- Rinse the tools thoroughly with water after cleaning, and dry them off.
5. Weed Killer
Baking soda can help manage weeds in your garden without resorting to harmful chemicals. While it’s not a complete solution for large-scale weed problems, it can be useful for killing weeds in cracks, sidewalks, or between stones.
How to use it:
- Simply sprinkle baking soda directly onto weeds, focusing on the roots.
- Be cautious, as it can affect the surrounding plants. Only use it where you don’t mind killing off vegetation.
6. Prevent Tomato Blossom End Rot
Tomato plants are prone to blossom end rot, a condition caused by calcium deficiency. Baking soda can help by adding calcium to the soil, preventing this common problem.
How to use it:
- Sprinkle a small amount of baking soda at the base of tomato plants.
- Water it in, ensuring it’s well absorbed by the soil.
