Is Baking Soda Good For Houseplants

Although it appears to do no harm, baking soda on plants occasionally can help stop the blossoming of fungus spores. Although it works best on fruits and vegetables that are still on the vine or stem, routine treatments in the spring help reduce foliar diseases like powdery mildew.

Leaf burn can be prevented by mixing 1 teaspoon (5 cc) baking soda with 1 gallon (4 L) of water. To make the mixture stick, add 1 teaspoon (5 ml) of dormant oil and 1/2 teaspoon (2.5 ml) of dish soap or horticultural soap as a surfactant. Remember that the solution is water soluble, therefore for optimal results, apply on a day that is dry and foggy.

Even though some tests and academic studies lessen baking soda’s efficiency against fungi, it won’t harm the plant and has immediate advantages, so give it a try!

BEFORE USING ANY HOMEMADE MIX: It should be noted that whenever a home mix is used, a little section of the plant should always be tested first to ensure that it won’t hurt the plant. Additionally, avoid washing plants with any detergents or soaps that include chlorine as this can be damaging to the plants. A home remedy should never be administered to any plant on a hot or sunny day, since this will cause immediate scorching and result in the plant’s eventual death.

How can baking soda be applied to houseplants?

Sodium bicarbonate, a fully natural and very alkaline chemical, is commonly referred to as “baking soda.” It is equally effective in cleaning a variety of household items, from greasy pots to mildewed shower stalls, as it is at leavening bread and other baked foods.

It consequently works well to clean plant leaves, which diligent gardeners frequently accomplish by spraying them with water or gently wiping them with a damp sponge. According to Plant Care Today, adding roughly 1/2 teaspoon of baking soda to filtered water will eliminate dust and improve the leaves’ ability to absorb sunlight, which is essential for survival and growth.

Similar to this, it has been observed that houseplants that appear lifeless respond favorably to watering with a solution made of 1 gallon of filtered water, 1 teaspoon each of baking soda, Epsom salt, and ammonia. However, if you enjoy cut flowers as well as geraniums, hydrangeas, and other plants that thrive in an alkaline environment, this recipe may not come as much of a surprise to you. These plants benefit from the addition of baking soda because they bloom more and last longer. For optimal results, according to HGTV, fill a vase with water, add 1 teaspoon of baking soda, and mix.

Can baking soda be used on plants in pots?

Almost all garden tools and surfaces can be cleaned with baking soda. While its alkaline action breaks down acids, filth, and grime, its gentle abrasiveness aids in removing tenacious deposits and stains. This can be used in the garden in a variety of ways:

  • Algae and filth can be removed from birdbaths by pouring baking soda on a damp rag and using it to scrape the basin. Your visiting birds will remain healthy if you keep your birdbath clean.
  • Prepare a solution of two tablespoons of baking soda and one quart of warm water to clean garden stones, walks, and walkways. Pour the solution onto the stone or walkway, scrub with a brush with firm bristles, and then thoroughly rinse.
  • Garden equipment should be thoroughly cleaned by soaking them in a basin of water first to get rid of any caked-on garden debris (you may add some baking soda to the soak if you like). Large mud and grime pieces should be sprayed off. Try combining baking soda and water to make a thin paste (try a 1:1 or 1:2 baking soda/water mix). Pour some baking soda directly on the stain or stubborn location, let sit for five minutes, then scrub and rinse.
  • Make a mixture out of liquid castile soap and baking soda to clean planters and flowerpots. (Castile soap is a natural vegetable oil-based soap renowned for its cleansing ability and ability to produce a good lather.) After cleaning your pots with the paste, give them a thorough rinse and allow them to air dry before stacking and storing.
  • Mix one gallon of warm water with one-half cup of baking soda and one tablespoon of dish soap to clean garden furniture and potting benches. Use this to clean outdoor furniture carefully. After cleaning, rinse thoroughly.
  • Alternately, for wicker or webbed chairs and furniture, cover the entire surface with a layer of dry baking soda. After 15 minutes, scrub it with a wet brush and rinse it off.
  • Garden equipment oil spills and stains can be removed by liberally sprinkling baking soda over the area and letting it settle to absorb as much oil as it can. Clean the area using a paste made of baking soda, salt, and dish soap after sweeping up the baking soda that has been soaked in oil (one part of each). When done, thoroughly rinse the area.

The best booster and spot solution for removing tough stains and grime from your garden clothes is baking soda. To increase the cleansing power of detergents and bleach while also serving as a natural fabric softener and odor-eliminator, add one-half cup of baking soda to each load of laundry. Additionally, baking soda can be combined with water to create a paste that can be applied directly on stains to be removed, including sweat stains (do note that baking soda will often cause dark colors to lighten and discolor, so spot testing in an inconspicuous area is advised).

How frequently should I give my plants baking soda?

For a very long time, baking soda has been used to cure plant powdery mildew. Once the plant has been harmed, it will function more as a preventative than a remedy.


  • Fill a big container with all the ingredients.
  • Mix thoroughly before adding to spray bottles.
  • Before usage, make sure the solution is thoroughly diluted and shaken.
  • Use on plants once a week to avoid powdery mildew.
  • Used more effectively on days with clouds than on sunny days.
  • The ion balance in fungal cells is upset by baking soda, which aids in protecting plants from powdery mildew.


Before applying to the entire plant, test on a few leaves first. The leaves may burn if the mixture is too potent.

Instead than treating powdery mildew that already exists, this fungicide works as a preventative measure.

Can plants be burned by baking soda?

In some circumstances, the sodium component of baking soda can cause the burning of plant elements such as roots and leaves.

Regular application of baking soda to plants can lead to an accumulation of bicarbonate in the soil, which affects soil nutrients and slows plant growth.

Another type of salt is baking soda, and overusing it harms plants in two ways:

First of all, it prevents the tissue cells of plants from functioning, which may prevent plants from absorbing the necessary amount of water.

Second, a plant that has too much salt in it may develop ion toxicity, which finally causes the plant harm.

Baking soda is typically safe to use as a fungicide on plants because it generally produces no severe issues when used moderately. It works wonders as a spray against fungus and herbivorous bugs. Additionally, it is organic and doesn’t hurt the environment in any way, making it a useful alternative to chemicals like suspended sc for plants in your garden.

It really is as easy as it seems. When insects consume sodium bicarbonate, their bodies emit carbon dioxide, which finally causes them to die.

Fungi rely on the plant’s energy to live or establish in. The plant’s vitality declines as the fungus spreads. Plant fungus can quickly harm your plant and ultimately cause it to completely fail.

Fungi can be found in the soil or in the air. They can enter a plant through the root or they can move through the air as spores and land on the plant’s leaves.

You should always conduct a patch test on your plants before applying the homemade solution, then wait to see how it works before applying it to the remainder of your garden. You can use this patch test to determine whether the concentration and dilution of the solution you made could result in the burning of leaves.

Typical preparation:

An efficient way to avoid any fungal infections or insects is to combine it in the sprayer and then spray it on the plants.

A broader spectrum of protection

This approach will work even better than the first one mentioned earlier. Dishwashing liquid will assist the solution stay where it is sprayed by increasing its viscosity, while adding oil will boost the solution’s capacity to kill insects or fungus-causing viruses. Powdery Mildew is a common disease that affects many different types of plants, especially if the growth season has been exceptionally damp. This remedy will aid in managing this disease.

A Powerful Option:

A solution is made considerably more efficient by the addition of neem oil. The Azadirachtin and Nimbin found in neem oil have fungicidal properties. Thus, a combination of neem oil and baking soda provides an even more potent remedy for fungi-related illnesses like Powdery Mildew. When your garden already has infected plants, this remedy is advised. The ingredient’s soap functions similarly to glue. It makes the solution more likely to adhere to the plant’s leaves and makes the fungal patches easier to get rid of.

Your plant can be kept secure and protected from any subsequent infestations by using baking soda in conjunction with other organic weed and pest control techniques.

In addition:

Only at dusk should the baking powder fungicide be administered. If you apply it on a sunny day or when the sun is out, your plant’s leaves may burn. Additionally, confirm that it won’t rain for the following 24 hours after application.

Baking soda’s fungicide can be used to treat existing fungal illnesses, but it works best as a preventative strategy. It is one of the most effective strategies to choose for prevention. It typically stops the development of disease-causing spores and effectively deters herbivorous insects. Never forget that prevention is always preferable to treatment. Baking soda and other natural therapies therefore function best when used in advance of issues.

What liquid encourages faster plant growth?

Although there are other widely used options, including milk, juice, and water, each has advantages and disadvantages, pure water remains the most trustworthy beverage for the best plant growth.

Can you use baking soda on succulents?

Early indications of this fungus include round, gray-brown spots on the surfaces of leaves and stems. As the infection worsens, these spots turn fuzzy with mold. It is the type of fungus that spreads when the weather starts to cool down and get damp, typically in the early Spring or Summer. It thrives in a moist, shaded area with poor airflow.

Dishwashing soap is one of the most used home-made fungicides in the early signs of a plant affected by grey mold. Just make sure it doesn’t contain bleach or greasers. The damaged regions of plants with severe grey mold infections must be removed. It’s best to refrain from watering from the top as well.

Leaf stains

Succulents can get fungal leaf spots indoors and outdoors, although they are not harmful. What makes it annoying is that when the fungus becomes too accustomed to your plant, the small area will enlarge and start to resemble a blotch, which will probably eventually kill your plant.

A succulent with Leaf Spots can be treated in a number of secure and practical ways. You can either spray your succulent with a moderate solution of bicarbonate of soda (baking soda), using 1/2 teaspoon per gallon of water, or you can use an all-purpose fungicide.

fungus wilt

Fusarium Wilt is a fungus that lives in the soil. It penetrates the plant through the roots and starts reproducing in the vascular tissues, obstructing the plant’s ability to absorb water, leading to severe stress, wilting, yellowing, and most likely, death.

Regrettably, there is currently no known cure for fusarium wilt in plants. The fastest removal and disposal of the infected plant is the best advised course of action for this fungus. Fusarium-contaminated soil must also be removed. This will aid in limiting the spread of the fungus.


A series of fungal infections known as anthracnose are brought on by members of the Colletotrichum genus. Circular, pale, sunken, or brownish patches that are characteristic of this type of fungus will cause the plant tissues to dry up and become hard like bark.

The only way to save your succulent once it has been attacked by this fungus is to remove the afflicted leaves. To further prevent the spread of this fungus, it is best to replace the contaminated plant’s soil and pot in addition to thoroughly cleaning all of your instruments.

You can apply fungicides that contain chlorothalonil, copper sprays with copper diammonia diacetate, propiconazole, and systemic fungicide thiophanate-methyl to eliminate any remaining fungal bodies and to maintain control.

Rotten Root and Crown

In comparison to other fungal illnesses, root and crown rots are among the hardest to diagnose. They don’t exhibit any distinctive symptoms that could enable you to identify an infection in your succulent.

To give you an example, a plant with root rot will first begin to wilt, then the leaves will start to turn brown, and finally the stems will start to rot, causing the plant to topple over. The roots will turn brown beneath the earth and will easily separate if the soil is carefully scraped away.

Fine feeder roots typically maintain a healthy white to tan color and can hold the root ball together effectively even if the root crown is also diseased. However, as soon as the plant’s soil is removed, brown spots can be seen on the cortex of the roots as well as the root crown or stem base.

Sadly, therapy does not work well for root and crown rot. However, this can be prevented by lowering moisture. Simply use a well-draining container and give your succulents the appropriate amount of water to achieve this. Just enough to meet the requirements of your plant. Additionally, any mulch that is longer than 4 inches should be removed to avoid letting your plant remain in excessively moist soil.
