Our Horticultural Grit is usually a mix of blacks, whites and greys, but occasionally it might be just the brown and greys or it could be blends of golds and buffs.
A teeny weeny 1-6mm this is perfect for potting up and for improving drainage, breaking up clay soil etc. and you can use it as a decorative gravel but just give us a bell or send an email over to double check what colour we've got in stock before you order!
