10 Best Mulch Glue 2025 in the United States

The Lockscape Sticky Rock Mulch Glue bundle is designed for landscaping tasks like securing mulch, gravel, or stones in place. One of its strong points is the inclusion of a high-quality 1-gallon pump sprayer, which makes applying the glue easy and even, avoiding common issues with cheap sprayers.
