Baking soda can harm plants if it is applied in high concentrations or repeatedly, as it can alter soil pH levels and cause nutrient imbalances.
And now, in greater depth
Baking soda, also known as sodium bicarbonate, is a popular household item that has many uses. One of its uses is in gardening, where it is used as a natural fungicide, insecticide, and to deter weeds. However, the use of baking soda on plants has its drawbacks and can harm plants if not used properly.
Applying baking soda in high concentrations or repeatedly can affect the pH level of the soil, making it too alkaline or basic for some plants. This can cause nutrient deficiencies and weaken the plants, making them more vulnerable to diseases and pests. In addition, baking soda can also be harmful to beneficial microbes that live in the soil, which play a crucial role in plant growth and soil health.
According to the University of Rhode Island, baking soda should only be used in small amounts and as a last resort for plant problems. “A solution of 1 teaspoon baking soda to 1 quart water can be used as a foliar spray to control fungal diseases like powdery mildew or black spot,” the university advises. “It should not be used on plants that are sensitive to high pH, such as potatoes.”
Here are some interesting facts about baking soda and its effects on plants:
- Baking soda has been widely used in agriculture as a natural pesticide and to prevent fungal diseases.
- While it can be a natural solution for plant problems, excessive use of baking soda can harm both plants and beneficial soil organisms.
- Apart from changing the pH levels in soil and causing nutrient imbalances, baking soda can also leave alkaline residue on plant leaves and stems, which can cause damage.
- Other household items that can be used in gardening include vinegar, which can be used to kill weeds, and Epsom salt, which can provide magnesium and sulfur to plants.
- The key to successful gardening is to maintain a balance in soil pH levels, nutrients, and beneficial organisms.
Table:
| Pros of baking soda in gardening | Cons of baking soda in gardening |
|---|---|
| Natural fungicide | High concentrations can alter soil pH levels |
| Natural insecticide | Repeated applications can cause nutrient imbalances |
| Deters weeds | Harmful to beneficial soil microbes |
| Widely available | Can leave alkaline residue on plant parts |
| Cost-effective | Should only be used in small amounts and as a last resort |
In conclusion, while baking soda can be a natural solution for certain plant problems, it should be used in moderation and with caution. It is essential to maintain a balance in soil pH levels, nutrients, and beneficial organisms for healthy plant growth and development. As the famous gardener, Beth Chatto, once said, “Right plant, right place.”
In this video, you may find the answer to “Will baking soda harm plants?”
The video explores the effectiveness of using baking soda in the garden and debunks common myths and misleading claims about it. While it can prevent the spread of powdery mildew and is a good cleaning product, it doesn’t work as an insecticide, fungicide, or fertilizer. Baking soda can even be harmful to plants and soil if used in excess due to its sodium content. The video advises caution when using baking soda in the garden and suggests keeping it in the kitchen.

Technically, yes. But practically speaking, it’s not ideal. Because high concentrations of sodium are toxic to plants, if you dump a bunch of dry baking soda onto a small plant, it will probably die. Also, because sodium is soluble, it’s likely to hurt or kill nearby plants that you didn’t want to harm.
Baking soda can be harmful to plants because high concentrations of sodium are toxic to them. If you dump a bunch of dry baking soda onto a small plant, it will probably die. Also, because sodium is soluble, it’s likely to hurt or kill nearby plants that you didn’t want to harm. However, 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.

You can give your ground cover plants like Bermuda grass and perennial ryegrass a boost by using baking soda to control pesky weeds. Then, you can combine baking soda with horticultural oil to increase the efficacy of powdery mildew treatments on your roses or euonymus bushes.
Mix them together and spray on your plant’s leaves twice a month as a preventative measure; or spray on the leaves every three days to treat an existing fungal problem.
