Treated with a natural humic acid that helps the soil and plants convert calcium into an immediately available form, Espoma Organic Lightning Lime is no ordinary limestone. Lightning Lime can work in just 6 to 8 weeks instead of the up to 14 months other lime products require. Lightning Lime raises soil pH and corrects acidic soil. Lightning Lime is also less dusty than traditional lime products and is approved for organic gardening. Pelletized for easy application. Safe to use around kids and pets.
