🪱 Wormery Care Checklist

Here's our quick and easy wiggly guide to looking after your worm composter - maybe print this page off and use it to make sure you're doing all you can for your worms.

✅ Every Week

  • ☐ Check moisture level
    Bedding should feel like a wrung-out sponge. If it's too dry, lightly mist with water. If too wet, add shredded paper or cardboard.

  • ☐ Feed a small amount of food waste
    1–2 handfuls per week is enough to start. Chop food up small. Avoid overfeeding.

  • ☐ Cover food with bedding or newspaper
    This prevents smells and fruit flies.

  • ☐ Check worm behaviour
    Worms should be under the blanket, not crawling up the sides or escaping. If they are, review moisture, temperature, and food.

  • ☐ Check the moisture mat
    Keep it damp. Replace if it starts to break down.

  • ☐ Drain liquid (leachate)
    If your wormery collects liquid, open the tap and drain it into a container. Use diluted (1:10) as plant food or discard if it smells bad.


Every Month

  • ☐ Gently stir the top layer
    This helps with airflow and breaks up any clumps. Be gentle—not too deep.

  • ☐ Add dry bedding
    Top up with shredded paper/cardboard to balance moisture and keep the worms happy.

  • ☐ Check for pests
    Look out for fruit flies, ants, or larvae. If present, reduce food, cover it better, and make sure the bin isn’t too wet.

  • ☐ Check temperature
    Worms like 15–25°C. In hot or cold weather, move the wormery somewhere more stable (shed, garage, shady spot).


Every 3–6 Months

  • ☐ Harvest compost
    When the bottom tray is full of dark, crumbly compost, it’s time to harvest! Rotate trays and add a fresh one on top.

  • ☐ Separate any straggler worms
    Pick out worms from finished compost and return them to the active layer.


🛠 Occasional Tasks

  • ☐ Replace worm blanket if it becomes soggy or disintegrates.

  • ☐ Wash trays (once or twice a year) with plain water—avoid soaps or chemicals.

  • ☐ Add crushed eggshells or lime occasionally to balance acidity.
