What is the shelf life of worm castings?

Worm castings, also known as vermicompost, are a rich and beneficial organic fertilizer, and their shelf life can vary based on several factors. Generally, when stored properly, worm castings can last for up to one to two years. It is crucial to keep them in a cool, dry place, ideally in a sealed container, to prevent moisture loss and protect them from pests. The nutrient content of worm castings may degrade over time, especially if they are exposed to air and humidity. If kept moisture-free and stored away from direct sunlight, worm castings will maintain their beneficial properties longer. It is essential to regularly check the condition of the castings, as any signs of mold or unpleasant odor may indicate they are no longer usable.
