Native Neems Organic Neem Granules are the residue left from the first extraction process, after the seeds kernels are crushed to extract the oil. This is a natural and organic product that prevents and kills nasty insects in the garden. If used at 4-6 weekly intervals you will very rarely need to use any other sprays. Good for all soils, all crops and all seasons. It works primarily by increasing the humus content of the soil.
