Yes, you can spray baking soda on plants, primarily as a natural fungicide for issues like powdery mildew, but it must be diluted with water and a drop of soap, applied carefully (avoiding direct sun), and used sparingly as too much can harm plants by increasing soil salt and pH, potentially causing leaf burn. A common recipe is 1 teaspoon baking soda, a few drops of liquid soap, and 1 quart of water, sprayed on foliage in the early morning.
Gardeners often use baking soda as a fungicide to treat diseases such as powdery mildew, black spot on roses, and other fungal infections.
Baking soda isn't just a great idea for outdoor plants; it can also benefit houseplants like prayer plants (Maranta leuconeura). Prayer plants have several names, including cathedral windows, herringbone plants, and rabbit tracks.
Can You Use Baking Soda For Pest Control? Baking soda is often used as an alternative pest control solution for pests such as cockroaches, bed bugs or ants.
Baking soda (sodium bicarbonate) has been used as a fungicide since 1933. Recent research has demonstrated that although baking soda can be effective against plant diseases when used with oil, its sodium component can build up and become toxic to plants.
Common Antifungal Remedies For Plants
Mix about 2 tablespoons of baking soda with one gallon of water (plus a couple drops of greywater-safe dish soap to help the solution stick to the leaves) and spray the plant's leaves.
Broad-spectrum Sevin Insect Killer Concentrate or Sevin Insect Killer Ready to Spray kills aphids, squash bugs and other listed sucking pests. Then it protects for up to three months. Once sprays dry, people and pets can reenter treated areas. Rasping-sucking pests like thrips cover leaves with tiny feeding holes.
A Cornell University researcher demonstrated that a mixture developed for powdery mildew—1 tablespoon of baking soda mixed in a gallon of water, with a bit of horticultural oil or liquid soap added to help it cling to the leaves—may also reduce the spread of black spot when used consistently.
You should not clean delicate surfaces like electronics, glass (mirrors, screens, cooktops), wood, aluminum, marble/natural stone, painted surfaces, or gold/silver-plated items with baking soda, as its mild abrasiveness can cause scratches, dullness, or damage finishes and patinas. It's best used for tougher grime where its abrasive quality helps, but avoided on anything requiring a delicate touch or specific sealant.
Make a typical baking soda spray by dissolving one teaspoon of baking soda into one quart of water. Optionally, add a few drops of insecticidal soap or liquid soap to help the solution spread and stick to the leaves. (Only use liquid soap, like Ivory, and not laundry detergent.)
Bugs hate strong, pungent, or overpowering natural scents, with peppermint, citronella, lavender, eucalyptus, and tea tree oil being top contenders, alongside vinegar and certain herbs like basil and rosemary, which disrupt their navigation and sensory systems. While no single scent universally repels all bugs, these strong aromas create an unpleasant environment, making them effective natural deterrents for common pests like mosquitoes, ants, and flies.
Soybean oil and olive oil
Soybean and olive oils slow the evaporation of essential oils once they're on your skin. A mosquito repellent with two-percent soybean oil offers one to four hours of protection against bites. Twenty-percent olive oil solutions have a 71 percent repellency rate for up to eight hours.
Cockroaches are most attracted to the smell of garbage and rotting food–one of the biggest reasons they enter homes is in search of food sources. Because of this, it is important to regularly clean your kitchen and remove your trash before it gets too full.
Combine Clove, Eucalyptus, Lavender, Peppermint or Rosemary oil with water in a spray bottle and spray your bed, linens, and other furniture lightly with a fine mist. Once this mixture air dries, the scent should repel dust mites.
Don't use too much, as this can alter the pH of your soil and negatively impact your plant's ability to take up nutrients. Avoid dusting your plants directly because the baking soda can dry them out, Springer adds.
For a good-smelling house, three simple ingredients often used are water, baking soda, and essential oils for an all-natural air freshener spray, or for simmering potpourri, you can combine citrus (like orange/lemon), cinnamon sticks, and cloves/vanilla extract to create a warm, inviting aroma, with baking soda tackling bad odors.
Baking soda neutralizes acids that harm surfaces inside the tank. This keeps the tank working well and lasting longer. It's simple but effective for mineral buildup and protecting parts inside the tank.
Early after the ingestion of too much baking soda, vomiting and diarrhea are common as the body tries to correct the high sodium concentration by pulling more water into the digestive tract. After absorption, high sodium concentrations can cause seizures, dehydration, and kidney failure.
Ultimate Stain Remover - DIY Solution! Ingredients: • 1 small spoon of Blue Dawn dishwashing liquid • 2 large spoons of baking soda • 4 large spoons of hydrogen peroxide Directions: 1. Mix Ingredients: Blend the Dawn, baking soda, and hydrogen peroxide together in a bowl until well mixed.
And although we're clear that plants need sugar to grow, it's not the LaCroix kind of sugar they are looking for. Flavored sodas could easily damage plant roots, breaking their immune systems down and leaving them prone to disease and death.
Unlike ants, roaches, or slugs, bed bugs are a category where baking soda falls short.
A solution of 1-5 tablespoons of baking soda per gallon of water is generally recommended. Start lower though, as 5 tablespoons can hurt the leaves in some cases. Efficacy is apparently improved by adding an equal amount of natural liquid soap or insecticidal soap, or an equal part of horticultural oil.
