SINGLE BAGS AVAILABLE FOR COLLECTION ONLY

Our Compost handy bags are roughly 40L, but exact measurements may vary depending on density and conditions.

Mushroom Compost is a nutrient-rich soil improver produced as a byproduct of commercial mushroom cultivation. This well-decomposed compost is high in organic matter, beneficial fungi, and trace minerals, helping to improve soil biology and overall fertility.

With a slightly alkaline pH, mushroom compost is particularly effective for improving acidic soils, while its crumbly texture enhances soil structure, aeration and moisture retention.

Supplied in convenient 40L bags, it’s ideal for borders, raised beds and general garden use. For larger projects, you may want to consider our Mushroom Compost Bulk Bag option.

First please measure the length and width of your area in metres to get your m2 measurement:

Length (m) x Width (m) = m2

For topsoil, please then multiply this by the depth required and by 1.2 to calculate how much you need:

m2 x Depth (m) x 1.2 = tonnes required

For compost:

m2 x Depth (m) x 0.6 = m3

Multiply your m3 measurement by 1000 to give litres of compost required.

*IMPORTANT* Please note that these are rough measurements, and the density of our products can vary due to environmental factors. If you are unsure, please fill in the quote form or give us a call on 01761 241387 so one of our team can help you make more accurate calculations.

Product Disclaimer & Natural Variations

All soils and compost products undergo rigorous testing to ensure compliance with chemical, physical, and nutrient quality standards. While we take immense pride in the quality of our premium topsoil and compost, please note the following characteristics of these natural, recycled products:

• Screening & Debris: Our products undergo a rigorous screening process to remove stones and contaminants. However, as a recycled organic material, we cannot guarantee the total absence of tiny debris or naturally occurring weed seeds.
• Natural Variation: Topsoil and compost are natural products; therefore, variations in colour, texture, and moisture content are expected and may vary from the product images shown or between different batches.
• Sourcing: We prioritise local, high-quality green waste and topsoil sourced from greenfield sites only. Because the raw ingredients change seasonally, the exact nutrient profile may fluctuate slightly.
• Storage: Once delivered, we recommend keeping the product covered if not used immediately to prevent the contamination of airborne seeds or saturation from heavy rain.
• Usage: It is the customer's responsibility to ensure the specific grade of topsoil or compost ordered is suitable for their intended planting or landscaping project.
