Benefits of Using Bark The application of bark mulch to your flower beds and landscaping designs will enhance your plants and lawn edges. Bark mulch adds that finishing touch that is both beautiful and functional. Bark mulch reduces maintenance by controlling weed growth, slowing evaporation and reducing the need for frequent watering. Bark mulch minimizes soil impaction and erosion and amends the soil while reducing the leaching of nutrients. Bark Mulch protects the root systems of plant by insulating them from temperature extremes, resulting in healthier plants. "Bark mulch is nature's sunscreen" Our Guidelines For Applying Mulch The recommended depth for mulch is 2 - 4 inches. We keep mulch at least 2 inches back from the trunks of trees and stems of shrubs. Mulch piled up against the trunks will encourage the growth of decay, disease and pests. At the beginning of the growing season, we apply 1 - 2 inches to compensate for decomposition of the mulch and to give it a fresh look. Multiply the length in feet X the width in feet = area in square feet. If the area you want to cover is not in straight lines, you will have to average the area. Area in Square ft.
