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.
