Composting at Cavell Community Park Garden

Composting is an important component of our Garden. The composting process converts raw organic material into a decayed, nutrient-rich mixture (or ‘compost’) that is beneficial to plants when added to soil.

There are currently two active bins for composting at Cavell: one is tumbler style, the other is fixed style.

  1. Guidelines for all Garden members (= basic practices):
    • Members may add any organic plants, either fresh or dried, from the Community Garden, to either of the active compost bins.
    • Do not add any other material (NO items from home; NO weeds; NO plants gone to seed, NO plants treated with pesticides or diseased; NO ‘brown’* items).
    • All items should be in small pieces, i.e., less than 2 inches square.
  2. Guidelines for compost-team members only (= expanded practices toward properly maintaining the compost):
    • Add to the active compost bins:
      • ‘green’** and ‘brown’ items, as needed, in layer fashion, always finishing with a layer of ‘browns’ (ideal ratio for each bin is 50:50)
      • mineral-heavy items (e.g., seaweed, egg shells [well-rinsed])
      • organic items only
      • small/shredded/torn items only
      • worms at the beginning of the season
    • Nothing else should be added.
    • Turn/stir regularly (i.e., once a week) to oxygenate pile.
    • Water as needed. (The pile should feel damp, like a wrung-out sponge. If a handful of the compost mixture is squeezed, only a little liquid should run out.)

* Examples of ‘brown’ (i.e., carbon-heavy) items include: dried leaves, grass cuttings, newsprint, paper, coffee grounds, sawdust (from untreated wood), peanut shells.

** Examples of ‘green’ (i.e., nitrogen-heavy) items include: organic plants, coffee grounds, tea bags, fruit.
