Give your plants the best with our premium worm castings, locally produced at Minnesota Worm Farm. We carefully craft our castings to ensure maximum quality—from a selective diet for our worms to minimal time between harvest and delivery.
Mix at a 1:10 ratio with your growing medium and keep moist for best results. Each gallon weighs approximately 4 pounds, and bulk 5-gallon options are available for larger spaces.
Unlike chemical fertilizers, worm castings won’t burn your plants, no matter how much you use.
Give your garden a natural boost with our premium worm castings.
