During the cold days at the beginning of the year, not everyone thinks about gardening. But in reality, this is the time when many plants easily face problems due to humid, cold weather and lack of sunlight. In this context, a simple garden care tip is being widely shared: utilizing baking soda (sodium bicarbonate) - a familiar ingredient in the kitchen - to create a DIY anti-fungal solution for plants.
Anti-fungal for plants using baking soda
This suggestion comes from Ish, a gardener who frequently shares experiences on his personal TikTok account. Ish's experience was cited by the Mirror newspaper. According to Ish, baking soda is not only used for cooking but also has many useful applications in the garden, especially during the early part of the year when humidity is high.
“Among the many uses of baking soda, one thing you can do for your garden is create an anti-fungal solution,” Ish shared. He emphasized that January is often “wet and miserable,” making some plants susceptible to fungal attacks.
How to mix the anti-fungal baking soda solution for plants
According to Ish's instructions, the way to mix the anti-fungal baking soda solution for plants is quite simple and does not require sophisticated tools:
Prepare a small spray bottle (about 500ml), fill it with water.
Add 1 teaspoon of baking soda to the bottle.
Shake well so that the baking soda dissolves completely in the water.
Gently spray the solution onto the affected leaves, once a week, to help handle fungal issues.
Ish believes this is a typical example of how things available in the kitchen cupboard “can become great helpers for the garden.”
Which types of fungi does this solution help plants fight?

In the video's caption, Ish explains further about the effect of baking soda on plants. According to him, baking soda can create a natural anti-fungal solution, helping to limit black spot, powdery mildew, and many other common fungal problems on plants.
The mechanism of baking soda lies in the fact that it slightly changes the pH on the leaf surface, while creating a “salt barrier” that makes it difficult for fungi to grow. As a result, plants are better protected in humid weather conditions.
However, this gardening expert also gave important notes when using baking soda for plants:
Only use baking soda in the correct dosage and diluted; avoid overuse as it can harm the plant.
Be cautious with salt-sensitive species, such as ferns, due to the risk of damage.
The solution is most effective when used for prevention, not for treatment when the fungus has already spread widely.
You should test spray on a small area of the plant first to observe the reaction before applying it to the entire garden.
When applied carefully, this is a small tip worth “pocketing” for gardeners, being both economical, environmentally friendly, and utilizing ingredients already available in the home.
