Baking soda has long been a kitchen staple, but it is quickly becoming a must-have in the garden for your plants. Experts say it can boost plant health, fight off pests, and even revive rusty tools. Here are five smart ways to put it to use outdoors no chemicals needed.
Baking soda acts as a natural pest repellent. Slugs can’t tolerate its salt content, and ants lose their scent trails around it. Experts suggest that using a flour sifter to lightly dust baking soda around your plants but not directly on them, as it can dry out leaves and alter soil pH.
Prevent common fungal infections like powdery mildew by spraying plants with a simple mix: water, a few drops of dish soap, and a pinch of baking soda. Many gardners recommend coating both the top and underside of leaves. Repeat weekly or after rain to keep your plants protected.
Some flowering plants love alkaline soil and baking soda can help. Mix a few teaspoons into a liter of water and spray around the base of alkaline-loving plants. Use with care, warn experts, as too much alkalinity can harm sensitive plants.
To get rid of unwanted weeds, wet them slightly and then sprinkle baking soda directly on top. The moisture helps the baking soda reach the root system. Be careful around other plants, as baking soda can affect nearby soil.
