Weed killing (with caution): A generous amount of baking soda sprinkled directly on young weeds can dry out and kill them. Be careful not to hit surrounding plants, as baking soda can also be harmful to them. This method is more suitable for paths or patio joints.
Compost odor removal: If your compost has an unpleasant smell, a thin layer of baking soda can help neutralize the odors.
Cleaner garden tools: A paste of baking soda and water can help remove rust and dirt from garden tools. Scrub the tools with it and then rinse them thoroughly.
Sweeter tomatoes (anecdotal): Some gardeners report that a pinch of baking soda sprinkled around the base of tomato plants can sweeten the fruit by slightly reducing soil acidity. However, this isn’t scientifically proven.
Influence hydrangea blooms (with caution): For certain hydrangea varieties (which respond to soil pH), baking soda, mixed into the soil, can help shift the flower color toward pink by making the soil more alkaline. Be very careful here and research your hydrangea variety, as incorrect use can be harmful.
Important note: Although baking soda can be a gentle alternative to chemical products in many cases, it should be used wisely in the garden. Overuse can negatively affect the soil pH and thus impair your plants’ growth. Always test the application on a small area first and observe your plants’ response.
