Building healthy soil doesn't require a truckload of fertilizer. These amendments are sold by the pound. Get just what you need for a single raised bed, a few grow bags, or a batch of soil blocking mix. Each one does a specific job: feeding roots, adjusting pH, adding calcium, building long-term soil structure. New to amendments? Start with Complete Organic Fertilizer for an all-in-one option, or ask us at an Open Garden day and we'll point you in the right direction.
