Siliceous fossil Soil Conditioner. Green Trading Diatomaceous earth powder is made up of tiny fossilized diatoms (plankton) that have accumulated over millennia in freshwater lakes. These pure deposits are mined and ground into a fine powder that is naturally high in silica and other minerals. It is this chalky white powder that we call diatomaceous earth.
Ingredients: 100% food grade, fresh water sourced diatomaceous earth powder
How to use: Sprinkle a light layer over soil to eliminate insects or dust over leaves after watering to help the powder stick to deter pests from eating the leaves.
