Eco Mix Organic Soil Improver questions
Q. What is organic soil improver?
Organic soil improver is a compost made up of organic matter. It improves the organic profile and structure of soil, creating a medium that has better drainage and growing properties. It can be dug into soil, or as a layer of mulch, which also protects plants in winter.
Q. How does soil improver help my garden?
In short, soil improver is a sustainable, organic fertiliser. If you have poor soil quality, adding soil improver to your garden helps plant health & growth. The organic matter breaks down, giving plants the nutrients they need and also improves water retention and soil structure.
Q. How much soil improver will I need for my garden project?
If you are looking to improve your soil, we recommend using a depth of 2cm. To mulch your beds and borders, a 5cm depth should be enough to keep them protected through the Autumn/Winter. To work out how much you will need, please use our free volume calculator.
