A blend of soil, graded ash, coarse sand, Nepean sand, composted sawdust, Botany Humus Mix and Composted Pine Bark. Suitable for planter box and rooftop application, our Planter Box Mix is especially useful for retaining moisture. It also helps prevent plant disease, speeding up root development with all plant, vegetable, and fruit species. As an A horizon soil, Planter Box Mix is created by blending organic material - composted green waste, composted sawdust, sand and composted pine bark. It is matured with spent coffee grounds added, creating a soil mixture that is also suitable for potting plants. It is also recommended that a slow release fertiliser is added upon planting.
