Osmocote Exact Lo Start is a 3rd generation-controlled release fertiliser which combines safety, batch-to-batch consistency and precise longevities. It has been developed especially for slow-growing conifers and salt sensitive crops. The nutrient release is relatively low at the start making it ideal for situations where a slow start is required, such as slow rooting young plants and early potting in tunnels. Osmocote Exact Lo Start 16-18M is also suitable for warm climates.
