Decomposition typically takes 1.5 months in Daily Dump composters. We recommend a further 1 month for full maturation. Compost should contain no recognisable food & should have an earthy smell. But, if you are trying to get compost into your garden quickly, it's best to mature it for another 2 months and test it before use. If it is a year old and has been kept moist for sometime - it is definitely ready!
