10 Incredible Ways to Use Baking Soda in the Garden
As a gardener, you’re always looking for natural, affordable solutions to keep your garden healthy and beautiful. One of the simplest items you probably already have in your kitchen is baking soda. This versatile powder can be a real game-changer in the garden. From pest control to plant health, here are 10 easy and effective ways to use baking soda in your garden.
1. Natural Fungicide for Plants
Fungal diseases like powdery mildew can ruin your plants. But baking soda can help! Its alkaline nature changes the pH on plant leaves, making it difficult for fungus to survive. You can make a simple homemade fungicide spray using baking soda.
How to Use:
- Mix the 1 tablespoon of baking soda with 1 gallon of water.
- Add a few drops of liquid soap (to help it stick to the plants).
- Spray this mixture on affected plants, focusing on the tops and undersides of leaves.
Apply every week, especially after rain, to keep fungi at bay.
2. Test Your Soil’s pH
Knowing whether your soil is acidic or alkaline is key for healthy plants. Baking soda can help you quickly figure this out. It’s not as precise as a soil test kit, but it works in a pinch.
How to Test:
- Wet a small patch of soil.
- Sprinkle baking soda over the damp soil.
- If it fizzes, your soil is likely acidic (low pH).
For a full test, do the same with vinegar (if it fizzes, the soil is alkaline).
3. Dealing with Weeds in Walkways
Weeds popping up in between pavers or in cracks on your walkway can be a pain. Baking soda offers a simple solution without the need for harsh chemicals.
How to Use:
- Sprinkle baking soda directly onto the weeds in cracks or on the paths where weeds grow.
This works by dehydrating the weeds, causing them to die off. Just be careful not to sprinkle too close to your plants, as baking soda can harm them too.
4. Sweeten Tomatoes
If you’re growing tomatoes and want to bring out their natural sweetness, baking soda might help. By lowering the acidity in the soil around the plants, it enhances the sweetness of the fruit.
How to Use:
- Lightly sprinkle baking soda around the base of your tomato plants.
Be sure to avoid getting it on the plants themselves and only apply it to the soil.
5. Control Pests like Ants and Aphids
Baking soda can help control pests like ants and aphids in the garden. You can combine it with other ingredients for a natural pest control solution.
How to Use:
- Mix the 1 tablespoon of baking soda, 1 tablespoon of sugar, and 1 tablespoon of water into a paste.
- Spread this mixture around areas where ants are a problem.
For aphids, sprinkle a mix of baking soda and flour on affected plants. The baking soda repels pests, while the flour helps it stick to the plants.
6. Keep Slugs at Bay
Slugs can munch on your leafy greens and tender plants. Luckily, baking soda is a natural deterrent for these slimy pests.
How to Use:
- Sprinkle baking soda directly on the slugs or around the base of plants where you notice slug activity.
It dehydrates slugs and keeps them from returning to your plants.
7. Freshen Up Your Compost Bin
A smelly compost pile can attract unwanted pests and make your garden less pleasant. Adding a bit of baking soda to your compost can help neutralize odors without harming the composting process.
How to Use:
- Sprinkle baking soda lightly over the compost when you notice strong odors.
Be careful not to overdo it—too much can slow down the breakdown of organic materials.
8. Clean Your Garden Tools
Keeping your garden tools clean is essential for preventing the spread of disease. Baking soda can be used to scrub dirt, sap, and rust off your tools, leaving them in great condition.
How to Use:
- Make a paste of baking soda and water.
- Use a scrub brush to clean your tools with the paste.
For tougher stains or rust, you can add a bit of vinegar to the mix for extra power.
9. Revive Your Rose Bushes
Roses are prone to fungal diseases like black spot, but baking soda can help protect them naturally.
How to Use:
- Mix 1 tablespoon of baking soda, 1 teaspoon of vegetable oil, and a few drops of liquid soap into 1 gallon of water.
- Spray this solution on your rose bushes every 7-10 days.
This mixture prevents black spots from taking hold and keeps your roses looking beautiful.
10. Boost Flower Blooms
Baking soda can encourage more blooms in flowering plants, like geraniums, begonias, and hydrangeas. It works by balancing the pH of the soil, which helps the plants absorb nutrients better.
How to Use:
- Add a small sprinkle of baking soda to the soil around your flowering plants.
Avoid using too much; just a light dusting will do.
