Biovermi nutrient tea is a concentrate and should be diluted before using. We suggest mixing 3 oz of Biovermi Humus tea to 1 gallon of water. Depending on what type of plants you are feeding you can use more or less. Since VermisTerra tea is organic and natural, you can apply it during growing and blooming seasons without hurting the plant. Once you mix Biovermi Humus tea with water, feed to plants within 24 hours (do not store).
