Tips on Seaweed Collection -
On public beaches you generally do not have to have permission to collect seaweed, unless collection is planned on an industrial scale. For the latter, the local authority must be contacted.
On private beaches you must contact the landowner and gain permission to collect.
Only collect seaweed that has washed onto the beach, collection of live seaweed can damage marine habitats.
Only choose seaweed that has recently been washed-up that looks and smells fresh. Old seaweed can breakdown and give off the rotten egg or stink bomb smelling gas hydrogen sulphide, which is dangerous to man and animals.
Ideally fork the seaweed into bags and don't have any physical contact with the weed itself; and wear thick gloves. Seaweed that is cast ashore can contain sharp objects, which including hypodermic needles / syringes, glass bottles, splintered or nailed timber and sharp shell fragments.
Over application can lead to the ground becoming too salty; this can lead to stunted growth, even plant death. Generally speaking though seaweed is one of the finest and cheapest ways of fertilising and improving the soil.
