Review on 💊 Soluble Ferrous Sulfate Heptahydrate (FeSO4·7H2O) by Shalom Germann

This £5 bag should be enough for 10,000m2. ft. Best applied with a liquid sprayer. Dissolve the powder in a bucket of water. Then mix well for about 5 minutes until all the powder is dissolved with the paint mixer. Pour into a lawn sprayer and evenly cover the grass. Water immediately after application for at least 5 minutes. Please note this iron is not of the highest quality but is clean enough for lawn use. Also, the mixture you stir first is strong enough to stain the concrete permanently. To transfer a solution only on a lawn or on asphalt. When diluted in a sprayer, the product leaves no noticeable stains on concrete, allowing you to spray to the edge of a concrete driveway.
