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.
