Absolutely. Gaia Green Worm Castings are OMRI Listed, meaning they meet the strict standards required for use in certified organic gardening.
You can either mix the castings directly into the soil before planting to improve structure or use them as a top dressing around the base of established plants. For an extra boost, many gardeners also use them to brew a nutrient-rich compost tea.
Worm castings are very gentle and have a low NPK ratio of 0.5-0.5-0.5. Because they are a natural, slow-release amendment, they are highly unlikely to burn your plants, even if you are slightly generous with your application.
