Composting at RBCG

We use CarbonCycle Composters at RBCG

Follow these 2 simple steps to make sure we end up with a great mix:

  1. Green

    Lift a couple of slats from the first box and tip in your kitchen or garden cuttings. Ideally they should be cut up into hand size pieces.

  2. Brown
    Cover the pile with brown waste from the big bins, at least the same quantity as the green waste you added

PLEASE NOTE, we don’t have a rubbish bin at the garden, any rubbish must be taken home with you.

*Almost anything organic from your kitchen can be composted.  Citrus, onion, garlic, and chilli can be composted (but not given to the worms-see below).  However, bread, meats, fish, dairy, and fats should be kept to a minimum because these don’t break down so readily or they get smelly, or draw flies and rats.

We currently have nine worm farms producing solid castings and liquid worm wee.  Worm wee is a wonderful liquid fertilizer, while castings condition the soil beautifully.  The worms will need to be fed regularly and drained as needed.  Worm wee should be diluted before watering your plants.  Excess undiluted worm wee should be added to the bin at the far end of the garden for others to use.

Feeding the worms: please feed them only as much as they can use.  It is better to feed them too little than too much as too much food will just rot.  A variety of fruit and veggie scraps are best, but other things can be fed to them as well (I’ve fed them old cotton shirts and even old ugg boots). However, worms DO NOT like citrus, onion, garlic or chilli.  Do not put bread, dairy, meat or fatty foods in there either.  If you don’t know or have any questions please ask someone.

A guide to looking after the worm farms is in the shed.
