Espoma Organic Lightning Lime

If you want an organic lime option, Espoma's Lightning Lime is the clear pick. Made from ultra-fine reactive limestone particles that break down faster than standard pelletized lime, it begins shifting pH within weeks rather than months. The OMRI-listed organic certification means no synthetic chemicals — it's safe around children, pets, and beneficial soil organisms immediately after application, which matters if you're seeding and your family uses the lawn. At a 30-lb bag covering 5,000 sq ft, the price per square foot is competitive with conventional limes. Espoma is one of the most trusted names in organic lawn care, and the lawn care community's experience with Lightning Lime has been consistently positive. For homeowners committed to an organic program, this is the no-compromise lime choice.
