Redworms (75-100 per cup) arrive wriggling and ready to start eating your trash. Set up your bin, lay shredded newspaper as bedding and occasionally add food scraps, grass cuttings, fallen leaves and other biodegradable garbage to the bin. Your worms will eat the trash you give them and create their own waste (worm castings). Collect castings and mix into potting soil, garden beds or simply sprinkle on potted plants. The castings are full of the nutrients plants need to grow, bloom and create tasty fruits and vegetables.
