Recycled crushed, washed and dried whelk shells. The large 12 litre bag contains approximately 11kg of shells, and is ideal for garden borders, beds, rockeries or as an outdoor plant pot topper.
The crushed shells can also be used for drainage or added to soil for aeration.
They also work well as mulch and as a gentle, natural slug deterrent when a generous layer is added around the base of plants - pour don't sprinkle!
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.

Pet Advisory:
As this is a natural seafood by-product, some pets may initially be attracted to the smell of the shells when first opened. We recommend supervising pets during initial use and discouraging consumption. While most pets show little interest once the shells are in place, ingestion may cause stomach upset, vomiting or digestive discomfort in some animals. If your pet consumes a significant quantity, we recommend seeking veterinary advice.

Reviews
Love love love these so far. Very aesthetically pleasing, show off plants to good advantage, white so they reflect the heat away from the roots ....
Yet to see how they perform re snails, shells, lily beetles etc, but hoping they will work well. i can vouch for the sharp edges (NB, use gloves, trowel, cup for spreading as it bl00dy hurts when a sharp edge goes under your fingernail!!!) and as lily beetles tend to drop and hide on the dark soil, the white shells will show them up well!!
In the previous years I’ve had a problem with slugs and snails eaten my young plants to the point of thinking about not growing any vegetables.
Then I found this product, which is brilliant, with the past week of rain it has been a good test, my Runner Beans are growing beautifully not been eaten.
Thank you Shell on Earth for an excellent product, fast delivery, can’t recommend highly enough.
Worth every penny for the sensory experience alone! The smell, sound and touch bring back memories of childhood British beach holidays on pebbled beaches, collecting shells and paddling in the sea.
The fact that this gorgeous product protects my flower and veg babies from slugs, aids drainage AND makes my plant pots and raised beds look beautiful is an added bonus!!
I love this product, I’ve used it on a couple of my potted plants and the finished is lovely.
It terms of being healthy for the plants I can’t say as it’s only been 2 weeks.
Everyone has said how lovely they look and will definitely be buying more for my boarders.
Easy order process, arrived quickly and in sturdy packaging, looks lovely on potted plants and has stopped the slugs, also goes a long way, well worth the money, thank you.
