EcoShells crushed sea shells, are crushed shells sustainably sourced from British seas for food consumption. The shells are then collected, washed and repurposed as decorative gravel.Ideal for decorative boarders or equally as striking used as outdoor pot toppers, indoor plant pot and terrarium dressing – great for cacti and succulents! Our shells are a great alternative to quarried grit or gravel. They can be used in large quantities in garden borders and beds, paths and driveways. The shells naturally lighten with sun exposure, giving a beautifully bright finish. For indoor plant pots we suggest a coverage of 20-30mm and when watering your plants, ensure a slow and gentle pour to avoid soil rising above the shells.
