Recycled crushed, washed and dried whelk shells.

This bag size is ideal for garden borders, beds, rockeries or as an outdoor plant pot topper.

The crushed shells can also be used as a drainage layer or added to soil for aeration.

It 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 and contains 3-4 times more crushed shells than our small hand-tied bags. 


*This is a natural product from the sea and we do our best to remove any foreign material. 

*All of our packing is recyclable. The protective white filler we include in our parcels is made from vegetable starch and is fully compostable.
