Good plant growth is a mix of the right watering, the right light, and the right nutrients. This Soil gives you a great start, but you should always plan on adding more organic fertilizer about one month after transplanting, or after your seeds grow their second set of leaves. Our Back to the Roots All-Purpose and Edibles Plant Food is 100% organic, contains root-boosting mycorrhizae to promote strong root growth, and is made without any synthetic chemicals or animal waste from big factory farms.
