Using our Certified Organic Compost can…

  • flower bedImprove soil organic matter levels
  • Increase nutrient holding capacity of soil
  • Improve soil structure and aeration
  • Increase water absorption
  • Improve drainage in heavy soils
  • Improved disease suppression
  • Minimise erosion

Why use organic compost?

Using certified organic compost improves soil structure, fertility and general soil health.

Healthy soil equals healthy plants and landscapes. Compost does a lot of the hard work for you by increasing the water holding and nutrient capacity of soil, meaning that less water and fertiliser is required for ongoing maintenance.

Organic compost can also be used to improve soil structure in problem soils.

Using quality compost on/in sandy soils increases water retention and nutrient holding capacity. In heavy clay-based soils, compost will improve filtration and drainage, as well as significantly increase the soil’s organic content. Improved soil structure also helps to prevent soil erosion, and regular compost use can decrease the need for chemical fertilisers.

Used as a mulch, compost boosts nutrient availability and plant growth, increases soil microbes and reduces weeding.

How to use our Compost



When using as a mulch, spread a layer 3 – 4 cm deep over the garden beds and around shrubs.
When preparing beds prior to planting, spread 4 – 5 cm layer of our compost and work in well. It is so much easier to add compost now than once the garden is planted.
When planting shrubs, dig a hole larger than required and place a good layer of our compost on the bottom, then mix equal parts compost and soil together, work around the root ball of the shrub and firm in. Water well.

When to Replenish

With perennials, every time you add a new plant to the garden or divide an existing one, add compost. With annuals, you can add compost every spring. Loosen up the entire area where annuals will be planted and work in compost. Around trees and shrubs add at planting time, mixing no more than 25 percent of soil volume. keeping the compost level at one-quarter of the total soil volume.
