Crushed Whelk Shells
An approximate 12 Litre bag of crushed, washed and dried whelk shells.
Perfect for pots, borders, beds, and rockeries.
The crushed shells can also be used as a drainage layer or added to soil for aeration.
They also works well as surface mulch and as a gentle, natural slug deterrent.
This bag will give a generous coverage for approximately 1/2 a square metre - a 20mm - 30mm layer is reccomended.
All packing is recyclable.
