Growing Media Guide

The foundation of a successful garden is getting the base right. Get the growing media right and the growth will follow. With so many options available it can be hard to know which growing media is appropriate.

What is growing media?

Growing media is what a plant is growing in. This covers soil, compost, seed raising mix, potting mix, garden mix, and specialty growing mixes like Tui Vegetable Mix. They are all mediums for growing plants.

What are the different types of growing media?

  • Compost is a soil conditioner and adds organic matter back into your soil.
  • Garden mix is for general use in your garden, for planting trees and shrubs.
  • Potting mix is for growing plants in containers, pots and hanging baskets.
  • Seed raising mix is for growing plants from seed.
  • Specialty mixes are for use in garden beds or pots and are specially formulated for groups of plants, for example Tui Tomato Mix contains the ideal nutrients for growing tomatoes.

What are the qualities of a good growing media?

The mix should be free-draining, allowing water to pass through for the plant to absorb, but without causing water logging and potentially root rot diseases. A good mix provides air- roots need oxygen like people do. When you open the bag, growing media should be dark brown in colour, lightweight and friable.

What are the extras a good growing media should contain?

  • Natural fertilisers like blood and bone, sheep manure, and gypsum. 
  • Time release fertilisers - these release nutrients to the plant over set periods of time for example 1, 3, 6 or 9 months.
  • Granular fertilisers like potash that boost fruit and flower development.
  • Wetting agents that help distribute water evenly through the soil, like Saturaid.
  • Water storing granules to retain water in the soil (usually for container plants).
  • Peat, pumice and coir fibre to for lighter, more open growing mixes.
