Our approach

From productive coastal water to healthier soil

Coastal Garden Supplies is run by Max and Pascale from Torpoint. We source PAS 100 certified green-waste compost from an established producer, then prepare and enrich it with ingredients derived from responsibly farmed kelp before supplying it as Coastal Compost.

Our kelp-derived ingredients come from cultivated kelp, grown without agricultural land or freshwater irrigation, rather than seaweed stripped from local shores.
