Mulching is a valuable practice for maintaining soil health. Apply a 2-3 inch (5-7 cm) layer of organic mulch, such as straw, wood chips, or shredded leaves, around the base of your Honeyberry plants. Mulch helps retain soil moisture, regulate temperature, and suppress weeds. Additionally, as it decomposes, mulch adds organic matter to the soil, improving its fertility and structure over time.
