Is mushroom compost suitable for all types of plants?

Mushroom compost is suitable for various plants such as vegetables, annuals, perennials, roses and shrubs by enhancing soil fertility and plant health due to its nutrient-rich content and soil improvement qualities.

However, it’s not suitable for ericaceous plants like rhododendrons, camellias, azaleas, and heathers that prefer acidic conditions.

What is the difference between soil conditioner and compost?

The difference between soil conditioner and compost is in the structure. You can grow plants and vegetables in compost but a good soil conditioner has to open a structure and roots would struggle to grasp it if it was the only substance to the bedding.

Can I use mushroom compost as a fertiliser?

Mushroom compost can be used as a slow-release fertiliser. Similar to other compost types, it gradually releases a variety of nutrients to plant roots as it breaks down. This characteristic makes it an effective choice for enriching the soil and enhancing overall plant/grass health by providing a steady and consistent nutrient supply over time.

How long does it take for soil conditioner to work?

It can depend on what time of the year you apply soil conditioner, but you can expect to see a difference within a couple of weeks.

Excellent product at a sensible price from a local supplier. Staff are friendly and willing to help: I asked if just one bag of topsoil could be delivered quickly and it arrived next day! Great service.

Smooth execution of the transaction and delivery. Very helpful phone call and conversation. Ordered three bags of Border Blend topsoil. Paid by Paypal. They delivered, on the specified date, carefully, exactly where I wanted the bags placed. All in all, a very pleasing purchase. The topsoil was excellent and had been very carefully prepared. No lumps. Would definitely recommend and I will use again. Everyone I spoke to was nice and helpful.

Ordered topsoil on Tuesday came by Friday at the exact time quoted. Was WAY cheaper than anywhere else (by about £15 per bag) and was dropped off via a crane on back of the lorry, not by pallet which most of the other places use. Soil was fine and dry. Brilliant !
