Gardening Tip: The Truth About Using Eggshells as Fertilizer

A recent online video from the "Be Light Candle RE" account, part of their "Grow Your Own Food Series," suggests a cost-effective method for fertilizing gardens using everyday eggshells. The video, uploaded on June 22, 2025, highlights eggshells as an ancient, all-natural fertilizer rich in calcium, beneficial for plants such as tomatoes, peppers, and melons. The creator demonstrates grinding eggshells and sprinkling them around plant bases, asserting that rainwater will naturally break them down, returning calcium to the soil. However, the efficacy of unprocessed eggshells as a rapid calcium source for plants is a topic of discussion among gardening enthusiasts and experts. Some viewers commented that eggshells, primarily calcium carbonate, are largely inert in soil unless the soil is acidic or the shells are processed with vinegar to make the calcium more readily available. This perspective suggests that while eggshells do contain calcium, their breakdown and nutrient release in typical garden conditions may be a very slow process, potentially taking many years to provide significant benefits.
