The powerful all-natural cleaning agent can also be used in the garden. Expert gardeners have been using the versatile ingredient in a variety of green cleaning methods and to eliminate many harmful pests.
Baking soda is made entirely of sodium bicarbonate and is a highly alkaline substance that you can use in your garden as a natural cleaning agent, a soil amendment, to care for plants, to control weeds and pests, to treat fungal diseases, and so much more. Here are 20 fantastic ways that you can use baking soda in your garden.
Baking Soda in the Garden
If you are one of the millions of households that have switched to green living, then baking soda has become an integral part of your life. Along with being a fantastic green cleaner, it has dozens of uses around the house and in your garden. If you are serious about tending an organic garden, then baking soda should be one of your top tools to use throughout the growing season.
Baking Soda Cleans Plant Leaves
Plants need photosynthesis to survive. To help all your plants make the most out of the sunshine, they do receive; you need to keep their leaves clean. You can do this by lightly wiping them with a sponge or cloth that is dampened with a diluted solution of water and baking soda. Add a half a teaspoon of baking soda to a liter of filtered water to make this gentle cleaning product.
Gives Your Plants a Boost in Your Garden
If your plants are beginning to look a little listless, you can use baking soda to give them a little boost. The following recipe can be used to water your plants to perk them up again.
Add all the ingredients to a large bucket. Stir to dissolve the baking soda and Epsom salt. Pour the mixture on your plants every month to perk up all your plants. Roses especially like this treatment.
Baking Soda Stimulates Blooming
Begonia, Geraniums, and Hydrangeas are all plants that like the soil to be more alkaline. Since baking soda is an alkaline ingredient, you can help stimulate their blooming by watering them monthly with a solution of one tablespoon baking soda and two quarts water. Feeding these plants every month with this special tonic will have them enthusiastically blooming all season long.
Keep Fresh Cut Flowers Longer
Mixing a tablespoon of baking soda with two quarts of water is a great way to keep your fresh cut flowers fresh for longer. For the best results, you want to change the solution every couple of days.
Adding Baking Soda Will Produce Sweeter Tomatoes
To make the dirt around your tomato plants less acidic, use baking soda. To get sweet tasting tomatoes, add a little Epsom salt as well.
Just sprinkle some baking soda over the soil that surrounds your tomato plant and then water. Having soil around your tomato plants that are less acidic means you’ll have less acidic tomatoes. For plants and where you need a more acidic soil, consider using coffee grounds in your garden.
Soil Testing and Amendment in the Garden
You can do a simple pH test on your soil with some baking soda. Your plant’s roots absorb the minerals found in the ground through their roots. If your soil is too acidic or alkaline it can hamper this process. You can conduct a simple home experiment using baking soda and vinegar to test your soil’s pH levels.
Place the two soil samples into a couple of small cups. In one of the cups, add the vinegar. If the soil bubbles, then your soil is alkaline. This means your soil has a pH level of seven or more. If it doesn’t bubble, then you can use the other soil sample to test the acidity. Add the baking soda to the water and then pour the solution into the second cup. If the soil bubbles with the mixture, then you have acidic soil with a pH level of seven or below.
If the test reveals that your soil is acidic, you can amend the problem by sprinkling baking soda over your soil just before you water. This should help to reduce the acidity of your soil. Continue to test your soil weekly until it no longer bubbles when exposed to water and baking soda.
Use Baking Soda to Prevent Fungal Disease
While baking soda won’t kill fungus on your plants, it will create a pH condition that is hostile to the growth of the fungus. To prevent fungus from growing, you’ll need to do the following.
Combine the water, baking soda, and liquid dish soap in a small bowl. Mix well to dissolve the baking soda. Add the solution to a spray bottle. Spray the top and bottoms of the leaves in the morning, when the weather is cold, so the leaves have ample time to dry.

If fungus and mildew have already set in on your plants, you can still treat it with a stronger solution that contains baking soda. Here’s a recipe for an all-natural mildew treatment for your plants.

Avoid getting any of the baking soda on plants that you don’t want to kill as the baking soda will burn their leaves.
Baking Soda Weed Killer
You can sprinkle a baking soda weed killer along your patio and walkways and in cracks and crevices to efficiently get rid of weeds.
