I ordered 20x20kg bags of Horticultural Grit to mix 50/50 with John Innes No3 bulk bag for ground preparation for a lavender hedge. Excellent delivery service, and excellent product. Thank you CPA horticulture.

Easy order, prompt delivery. Helpful and friendly driver. As it was my first ever order of horticultural grit I am not sure what to expect. Hopefully will help to break very heavy clay soil.

Thanks for sending me the horticultural grit. It’s very fine, but coarser than sand. It’s perfect for breaking up a heavy soil. I’m very pleased with it.
