Mulching around your Chives can significantly benefit soil health. Organic mulches, such as straw, grass clippings, or shredded leaves, help retain soil moisture, regulate temperature, and suppress weeds. Mulch gradually decomposes, adding organic matter to the soil and improving its structure. Apply a 2-3 inch (5-7.5 cm) layer of mulch around the Chives, ensuring it's not piled against the stems to prevent rot.
