Grow bigger, more beautiful plants with Miracle-Gro® garden soil all-purpose. This soil for in-ground use feeds plants for up to 3 months and improves existing soil to build strong roots. Use with your outdoor in-ground plants, including flowers, annuals, perennials, trees and shrubs. To apply, spread 2 to 3 in of soil in your garden bed or other in-ground area. Mix into the top 6 to 8 in of native soil. Dig a hole and plant your new plants. When planting individual plants, dig hole 2X as wide as the container or root ball, and blend a 50:50 mix of garden soil and native soil.
