Understanding Baking Soda and Its Properties
Chemical Composition of Baking Soda
Baking soda, also known as sodium bicarbonate, is a chemical compound that consists of sodium, hydrogen, carbon, and oxygen atoms. Its chemical formula is NaHCO3, which means it contains one sodium (Na) atom, one hydrogen (H) atom, one carbon (C) atom, and three oxygen (O) atoms.
Alkaline Properties of Baking Soda
Baking soda is known for its alkaline properties, which means it has a pH greater than 7. A 1 percent molar solution of baking soda in water at room temperature has a pH of 8.3. This number indicates that baking soda is alkaline, which accounts for its bitter taste.
When baking soda is mixed with an acid, such as vinegar, it creates a chemical reaction that produces carbon dioxide gas. This reaction causes the mixture to bubble and fizz, which is useful for cleaning and cooking purposes.

In gardening, baking soda can be used to adjust the pH level of soil. If your soil is too acidic, adding baking soda can help neutralize it and make it more alkaline. However, it is important to use baking soda in moderation, as too much can harm your plants.
Overall, baking soda is a versatile compound that has many uses in cooking, cleaning, and gardening. Understanding its chemical composition and alkaline properties can help you use it effectively and safely.
Baking Soda in Gardening
Baking Soda as a Fertilizer
A good source of sodium, an essential nutrient for plant growth, baking soda is a great natural fertilizer for plants. Baking soda can also help to improve the texture of the soil and make it more conducive to plant growth.
To use baking soda as a fertilizer, sprinkle a small amount around the base of your plants. Be careful not to use too much, as it can raise the pH level of the soil.
Baking Soda for Soil pH Control
Baking soda can be used to control the pH level of your soil. If your soil is too acidic, adding baking soda can help to raise the pH level and make it more alkaline. This is especially useful for plants that prefer alkaline soil, such as hydrangeas and lilacs.
To use baking soda for soil pH control, mix 1 tablespoon of baking soda with 1 gallon of water. Apply the mixture to your garden beds or directly to the soil around your plants. Don’t know the pH level of your soil? You can easily measure the pH level of your soil with this inexpensive pH level soil testing kit.
Baking Soda as a Weed Killer
Baking soda can also be used as a natural weed killer. It works by drying out the leaves of the weeds, causing them to wither and die.
To use baking soda as a weed killer, mix 1 tablespoon of baking soda with 1 gallon of water. Add a few drops of dish soap and mix well. Spray the mixture directly onto the leaves of the weeds, being careful not to get any on your plants.

Baking soda is just one of many natural fertilizers and soil amendments that can be used in gardening. Other options include epsom salt, coffee grounds, and various commercial fertilizers. When using any fertilizer or soil amendment, it is important to pay attention to the pH levels of your soil and adjust accordingly.
Baking Soda for Plant Diseases and Pests
If you’re looking for a natural and effective way to keep your plants healthy and pest-free, baking soda may be the answer. Baking soda has been used for centuries as a natural remedy for various ailments, including plant diseases and pests. In this section, we will discuss how baking soda can help your plants fight off fungal diseases and pests.
Baking Soda for Fungal Diseases
Fungal diseases such as powdery mildew, black spot fungus, and early blight can wreak havoc on your plants. Fortunately, baking soda can help prevent and control these diseases. Baking soda works by disrupting the fungal spores and preventing them from germinating. To make a baking soda spray, mix 1 tablespoon of baking soda, 1 tablespoon of horticultural oil, and 1 tablespoon of liquid soap in 1 gallon of water. Spray the solution on the affected plants every 7 to 14 days, or as needed.
Baking Soda for Pest Control
Baking soda can also be used to control pests such as aphids, snails, cabbage worms, and spider mites. It works by disrupting the insects’ exoskeleton and causing them to dehydrate and die. To make a baking soda spray for pests, mix 1 tablespoon of baking soda, 1 tablespoon of liquid soap, and 1 gallon of water. Spray the solution on the affected plants, making sure to cover both the tops and bottoms of the leaves.

Cautionary Measures with Baking Soda
When using baking soda on your plants, it is essential to take some precautions to avoid any potential risks. Although baking soda is generally safe to use, it can be harmful to plants, pets, and children if not used correctly. Here are some things you need to consider before using baking soda on your plants:
Potential Risks for Plants
While baking soda is an effective fungicide, it can also cause defoliation and damage to some plants. Azaleas and rhododendrons are particularly sensitive to baking soda and can suffer from leaf burn and other issues if exposed to high concentrations of baking soda. Additionally, baking soda can interfere with the uptake of essential nutrients like manganese, calcium, and aluminum, which can lead to nutrient deficiencies in your plants.
Safety for Pets and Children
Baking soda is generally safe for pets and children, but it can be harmful if ingested in large quantities. Keep your pets and children away from areas treated with baking soda, and make sure they do not accidentally ingest it. If you are using baking soda in your garden, consider fencing off the treated area to prevent your pets and children from coming into contact with it.
Impact on Pollinators and Birds
Baking soda can also have an impact on pollinators and birds. While baking soda is not toxic to birds or bees, it can interfere with the pH balance of the soil and create an alkaline environment that is not suitable for some plants. Additionally, baking soda can also reduce the effectiveness of natural pest control methods like neem oil and aspirin.
To minimize the risks associated with using baking soda on your plants, it is essential to follow the instructions carefully and use it sparingly. Avoid using baking soda on sensitive plants like azaleas and rhododendrons, and make sure you do not apply it directly to the leaves of your plants. If you have any concerns about using baking soda on your plants, consult a professional gardener or horticulturist for advice.
