Premium mixes hold nutrients and have good aeration and excellent water holding ability.

The old saying that 'you only get what you pay for' is true with potting mix, so go for the best you can within your budget.


Potting mixes are often formulated with specific plants in mind. This is to ensure that growing plants have everything they need for optimal growth.
Always choose a potting mix designed for the plants you wish to grow, like vegetables and herbs, or indoor plants.

Fertilisers and nutrients

A good quality potting mix will have a fertiliser incorporated into the mix to support plant growth for at least three to six months. Controlled release fertiliser or slow release fertilisers that may include natural nutrients are essential to support the developing seed, seedling or plant.

Soil wetters

Premium or professional potting mixes should not become water repellent (hydrophobic) because of the quality of the ingredients used to make them. However, wetting agents and water storing crystals may be incorporated in the mix to improve moisture penetration and retention as well as nutrient uptake.
