Do I Need to Stir, Rake or Shred Compost?
Monday, 23 January 2012 | HOTBIN Composting
It is desirable, but not essential, to occasionally stir or rake new waste into the active upper layer (10-20 cm).
This mixes bacteria in active layer with new material increasing speed. It also reduces the build up of wide air channels that can create pockets of dried compost.
Raking is very different from traditional turning and forking that requires a huge volume of material to be moved and reset as a new heap. Please see our turning article
Smaller pieces of waste compost faster so it is helpful to chop things up. You do not need a shredder - you can get by using secateurs to chop up small volumes of woody waste. A shredder is very useful when you have lots of woody material.
Where the HotBin is concerned, the advice is to chop waste preferably to less than 2 cm but always less than 4 cm. Do not mash or pulp your waste!
