How it works...

Throughout history seaweed and its effect on plant growth has been well documented. Seasol is a plant health treatment that contains a synergistic range of natural compounds, trace elements, alginates and other bio-active compounds that help to promote healthy roots, encourage beneficial soil micro-organisms, stimulate flowering and fruiting and help plants to cope with heat, drought and cold stress.
