How to make compost in a tumbler?
Throw in a handful of dirt which will contain composting bacteria . Then add your 2 parts kitchen waste and 1 part shredded cardboard daily or every few days whenever convenient. Voila . Toss the dirt or compost in with kitchen scraps and raked leaves or sawdust for best results. Feed your tumbler every 1 to 2 days until the chamber is about 4 in (10 cm) from the top.Chopping or shredding materials like kitchen scraps and paper will speed up the composting process. Having larger, bulkier woody waste can help keep pockets of air in the tumbler, which helps. A balanced mix of green materials (high in nitrogen) and brown materials (high in carbon) is essential.
