There's no better way to get your garden growing fast, fresh, and healthy than with some homemade compost. The Miracle Gro 70 Liter Dual Chamber Outdoor Compost Tumbler Mixer provides plenty of space to keep a continual composting operation going all season long. The double compost tumbler features 2 chambers, allowing you to use the fresh compost from one chamber while another batch is fermenting in the second. Just add your compost ingredients to the chamber and give the handle a spin. Aerator holes and internal mixing bars make sure the materials are properly combined and are able to decompose. Just give the outdoor composting bin a tumble every few days and in 4 to 6 weeks, you'll have a batch of nutrient-rich fertilizer for your garden.
