YOUR article on harvesting seaweed ("'Harvest from the seas may aid economy in the Highlands", The Herald, August 15), quite correctly suggested its many and varied uses – food, paint, cosmetics, medicine and so on – that this valuable resource can be put to. I would add another use, for gardeners. Seaweed makes a useful addition to the compost heap. Mixed with grass cuttings, kitchen waste, farmyard manure, annual weed, old bedding plants and the like it provides a most valuable organic tonic for your allotment or community garden.
