Soil Improver FAQs
What is soil improver and how is it different from compost?
Soil improver is a broad term for organic material that’s added to soil to enhance its structure, fertility, and microbial activity. It’s typically coarser than compost and is used to improve the overall condition of soil rather than as a growing medium on its own. Alsoils+ Soil Improver is made from composted organic matter and is ideal for digging into beds and borders to break up heavy soils and boost nutrient levels.
When is the best time to use soil improver?
The best time to apply soil improver is in autumn or winter, once the main growing season has ended. This gives the material time to break down further and enrich the soil before spring planting. It can also be used in early spring as part of bed preparation, especially for vegetable patches and flower borders.
Is Alsoils+ Soil Improver peat-free and environmentally friendly?
Yes. Alsoils+ Soil Improver is fully peat-free and made from sustainably sourced, composted organic matter. It’s a natural and eco-conscious way to improve your soil’s health without depleting vital peatland habitats.
How much soil improver do I need?
As a general guide, one 0.75m³ bulk bag covers approximately 10–12m² when spread at a depth of 50–75mm. For beds, borders, and allotments, it’s typically recommended to apply a generous layer and dig it into the top 15–30cm of soil. If you’re still unsure, try using our soil improver calculator.
