Gardening lime is a soil additive made from pulverized limestone or chalk. It’s used to raise the pH level of acidic soils, making them less acidic and more alkaline. This helps create optimal soil conditions for growing plants that thrive in neutral or slightly alkaline environments. Lime also provides calcium and magnesium, which are essential nutrients for plant growth. Over time, acidic soils can cause nutrient deficiencies and toxicities that stunt plant growth, so adding lime counteracts this. According to the University of Minnesota Extension, it’s commonly used for vegetable gardens, lawns, and landscaping.
