Australian Standard 3743 sets the minimum bar for potting mixes, but “minimum” won’t win blue-ribbon tomatoes or glossy indoor foliage.
If you’re filling raised beds rather than pots, the Best Soil for Raised-Bed Gardens in Australia (2025 Guide) outlines the exact soil structure that supports high-yield veggie beds nationwide.
We hear time and time again from customers that our mixes smash this benchmark. Below are our standouts and where they fit best in your garden.
