Seasol Commercial is a 100% liquid seaweed plant conditioner that provides a synergistic range of natural compounds, trace elements, alginates and carbohydrates from a blend of brown kelps. The seaweed is not harvested from living stands, but sustainably sourced from storm-cast material collected from remote locations that are free from pollution. This ensures the highest possible quality and consistency in every drum. Seasol is a plant stimulant used to boost plant metabolism. It is 100% soluble and can be applied either to the soil or the foliage. It is designed to provide benefits that complement your existing fertiliser program. These benefits result in a general increase in overall plant health.
