Sodium Bicarbonate In Gardens: Using Baking Soda On Plants


By: Bonnie L. Grant, Certified Urban Agriculturist

Baking soda, or sodium bicarbonate, has been touted as an effective and safe fungicide on the treatment of powdery mildew and several other fungal diseases. Recent studies confuse the efficiency of using this common household item. The compound seems to prevent some fungal spore flare ups but doesn’t kill the spores.

Is baking soda good for plants? It certainly doesn’t seem to do any harm, but it isn’t the miracle cure for those mildew beleaguered roses either. Baking soda as a fungicide does appear to diminish the effects of fungal diseases on common ornamental and vegetable plants.

Sodium Bicarbonate in Gardens

Numerous trials have been done to study the effects of baking soda sprays on plants. The ATTRA organization, which assists rural and agricultural growers with common production issues and plant information, published a series of findings from trials across the globe. Overall, baking soda on plants had a beneficial effect in reducing fungal spores.

Some concerns, however, were raised over sodium bicarbonate in gardens because of the first part of the compound. Sodium can burn leaves, roots and other plant parts. It can also stay in soil and affect later plants. No serious buildup was found, however, and the Federal EPA has cleared sodium bicarbonate as safe for edible plants.

Using Sodium Bicarbonate on Plants

The best concentration of baking soda is a 1 percent solution. The remainder of the solution can be water, but coverage on the leaves and stems is better if some horticultural oil or soap is added to the mixture.

Sodium bicarbonate as a fungicide works by disrupting the ion balance in the fungal cells, which causes them to collapse. The biggest danger in using sodium bicarbonate on plants is the potential for foliar burn. This appears as brown or yellow patches at the end of the leaves and can be minimized by thorough dilution of the product.

Is Baking Soda Good for Plants?

Baking soda on plants causes no apparent harm and may help prevent the bloom of fungal spores in some cases. It is most effective on fruits and vegetables off the vine or stem, but regular applications during the spring can minimize diseases such as powdery mildew and other foliar diseases.

A solution of 1 teaspoon (5 mL.) baking soda to 1 gallon a (4 L.) of water reduces instances of leaf burn. Add 1 teaspoon (5 mL.) dormant oil and ½ teaspoon (2.5 mL.) of dish soap or horticultural soap as a surfactant to help the mixture stick. Keep in mind the solution is water soluble, so apply on a dry cloudy day for best results.

While some trials and scientific research mitigate the effectiveness of baking soda against fungal diseases, it won’t hurt the plant and does have short term benefits, so go for it!

BEFORE USING ANY HOMEMADE MIX: It should be noted that anytime you use a home mix, you should always test it out on a small portion of the plant first to make sure that it will not harm the plant. Also, avoid using any bleach-based soaps or detergents on plants since this can be harmful to them. In addition, it is important that a home mixture never be applied to any plant on a hot or brightly sunny day, as this will quickly lead to burning of the plant and its ultimate demise.

How to Use Baking Soda as Organic Fungicide for Your Garden

Updated 08/07/2020

The use of baking soda as a fungicide is not new and has long been utilized by gardeners to protect their plants. Scientifically known as Sodium Bicarbonate, it has been an effective and safe fungicide for the treatment of various fungal diseases such as powdery mildew. It is also effective at eliminating the effects of fungal diseases on common vegetable plants.

When baking soda is sprayed on plants, it disrupts the ion balance of fungal cells, which causes them to collapse. Also, fungal spores are eliminated because the baking soda leaves alkaline residues on the surface of plants.

Apart from acting as a fungicide, it has several other benefits in the garden. These include but not limited to:

Keeping plant leaves and flowers fresh and clean.

Sweetening the taste of tomatoes.

Let’s dive a bit deeper into the pros and cons of using baking soda as a fungicide.

Advantages:

It is organic and eco-friendly.

It is less expensive than commercial fungicides and does the job perfectly.

It prevents mold from growing on plants.

Disadvantages:

The first compound of baking soda, sodium, can burn roots, leaves and other plant parts in some cases

Consistent usage of baking soda on plants can cause bicarbonate to accumulate in the soil thus it has an impact on soil nutrients, which will lead to slower growth of the plant.

Baking soda is also a kind of salt, and its excessive use hurts plants in two ways:

Firstly, it blocks plants’ tissue cells and as a consequence, plants may become unable to take in the amount of water they require.

Secondly, too much salt can accumulate in the plant and cause, ion toxicity which eventually harms the plant.

However overall, and when used in moderation, baking soda causes no major problems and is therefore generally safe to use as a fungicide on plants. As a spray, it can achieve amazing results against fungus and herbivore bugs. Also, it is organic and doesn’t cause any kind of harm to the environment thus, it is a handy solution for plants in your garden if you don’t want to sprinkle chemicals like suspended sc out there.

How does it work?

It is as simple as it sounds. Upon ingestion by insects, the compound sodium bicarbonate releases carbon dioxide into their bodies, eventually leading them to death.

How can fungi affect plants?

Fungi survive on the energy from the plants they live or settle in. As the fungi grows, the vitality of the plant diminishes. Plant fungus can quickly damage your plant and eventually a total plant collapse.

Fungi come either from the air or from the soil. They travel through the air via spores and settle onto the plant’s leaves, or they may enter a plant through the root.

Making Fungicide Out of Baking Soda

Before spraying the solution made at home, you should always perform a patch test on your plants and wait to see how it performs before spraying it in the rest of you garden. This patch test will also help you know if the concentration and dilution of the solution you prepared might lead to the burning of leaves.

A common preparation:

3 Tablespoons of Baking Soda

Mixing it in the sprayer and then spraying on the plants can be an effective preventive method against any fungal diseases or insects.

A wider range of protection:

1 Tablespoon Oil (Preferably Vegetable Oil)

2 Drops dishwashing liquid

This solution will be even more effective than the first one described above. The oil will increase the solution’s ability to kill insects or fungal viruses, while adding dishwashing liquid will help the solution stay where it is sprayed by increasing its viscosity. This solution will also help in controlling the fungal disease “Powdery Mildew”: a common disease that afflicts many types of plants, especially if the growing season has been particularly wet.

A Strong Solution:

2 TableSpoons Baking soda

1 Tablespoon soap (Recommended: Castille Soap)

The addition of neem oil makes an even more effective solution. The neem oil has fungicidal benefits from the Azadirachtin and Nimbin it contains . Therefore, neem oil and baking soda, when mixed together, offer an even more effective treatment against fungal diseases like Powdery Mildew. This solution is recommended when you have already infested plants in your garden. The soap in the ingredient works the same as glue. It helps the solution to stick to the leaves of the plant and can eliminate the fungal spots more effectively.

Using baking soda in combination with other natural methods of repelling pests and weeds can keep your plant safe and protected against any further infestations.

The baking powder fungicide should be only applied while it’s dusk. Applying it on a sunny day or when the sun is out might lead to the burning of your plant’s leaves. Also, make sure it won’t rain within the next 24 hours after application.

Fungicide made by baking soda works best as a preventative measure, but it can also be effective in eliminating existing fungal diseases. For prevention, it is one of the best working methods to opt for. In most cases, it prevents the formation of spores that cause diseases and is effective at keeping herbivore insects away. Always remember that prevention is better than cure. Therefore, baking soda and other such natural remedies work best before you have problems.

3. Use Baking Soda to get rid of Powdery Mildew

If your rose is invaded by powdery Mildew and the plant is becoming unhealthy then its use is beneficial. Use baking soda spray to prevent powdery mildew. 7 spoons of sodium bicarbonate, a little bit of liquid soap, 5-gallon water mix well. Spray the prepared mixture for a few days. Always check, some plants may be sensitive to it because of which can burn. Sprinkle the mixture once a week for better results.


5 more uses for baking soda in the garden:

1. Eliminate powdery mildew: Mix 1 tablespoon baking soda, 1 gallon water, 1 tablespoon vegetable oil, and 1 tablespoon dish soap. Spray weekly on affected plants.

2. Refresh rose bushes: Water roses with 1 teaspoon baking soda, 1/2 teaspoon clear ammonia, and 1 teaspoon Epsom salt in a gallon of water.

3. Make a fungicide: Combine a gallon of water with 1 tablespoon baking soda, 21/2 tablespoons vegetable oil, and 1/2 teaspoon of castile soap. Spray on the foliage of diseased plants.

4. Test your soil pH: Wet the soil and sprinkle a small amount of baking soda onto it. If the baking soda bubbles, your soil is acidic with a pH level under 5.

5. Repel garden pests: Rabbits, ants, silver fish, and roaches don’t like baking soda. Sprinkle it on the perimeter of your garden to keep them away.

Baking Soda And Insect Control

Does baking soda kill insects? Yes.

Whether you have a roach, ant, slug, rat, or bed bug problems, baking soda can be used effectively against such pests. The process for using this compound may vary depending on the type of pest problem being faced.

Ants

A bait is prepared using equal parts of sugar and baking soda.

Ants get easily attracted to sugar and will waste no time swooping on your bait. Once ingested, the effects of the baking soda kicks in. It reacts with the acid in their digestive system which is very toxic and kills them in no time.

Roaches

Roach extermination can also be done using this natural method. Similar to ant control, a roach bait is prepared by mixing equal parts of sugar and baking soda. While the sugar serves to attract roaches, the baking soda does the job of killing them.

Once ingested, it becomes poisonous when reacting with the acid in their digestive system. When making this bait, it should be mixed in a shallow bowl and placed around areas where roaches are common, especially the kitchen area.

This process can be repeated until there’s a clear improvement in your pest situation.

Using baking soda for roaches has proven to be effective. As we’ve seen, it can either be used alone or as bait by mixing it with other substances like sugar. This provides natural relief in addition to being inexpensive. It can also be used together with other pest control methods.

Baking Soda Use in Pest Control – Safety Considerations

This is an important aspect of pest control. Baking soda, in this case very harmless.

It is used around the home for several purposes including personal hygiene as well as a cleaning agent. This can be generously applied for the best results.
