New, revolutionary Miracle-Gro Patch Magic offers a convenient, easy to use, one step solution to bare or thin patches in your grass. Made up of a superior quality (free from agricultural grasses) mix of grass seed, coir growing substrate and Miracle-Gro fertiliser, grass is guaranteed to grow anywhere, even on concrete, and grows 50% thicker with 50% less watering. The unique, super-absorbent growing material acts like topsoil and changes colour to indicate when more watering is required.
