What this sheet is for
Catch overfeeding before the bin turns wet and sour by noting what went in and how it looked. Harvests and fixes are kept alongside, so you learn what your worms will manage.
Who it is for
Home and school wormery keepers, allotment holders and anyone composting food waste with worms.
How to use it
- Write a line each time the lid comes off: what went in, roughly how much, and any bedding added.
- Note the moisture, smell, any flies or mites and how busy the worms are.
- Record any liquid drained off.
- Log each harvest on page two, with where the compost went and the worms returned.
- Write down any problem and what was done, so the fix is there next time.
What is on the sheet

Page 1
Printed under the title: Everything that goes into the worm bin and how the bin looked when it did: moisture, smell, flies, the worms themselves and the liquid drained, then each harvest of compost and the problems put right.
Feed what they clear. No amount or feeding interval is printed here. Feed what the worms are clearing, in whatever measure you use, and let the moisture, smell and pest columns show when the bin is getting more than it can manage. A run of wet, sour checks is the sign to look at what is going in.

Questions
Why is there no feeding amount printed?
Because it depends on the size of the bin, how many worms are in it, the time of year and what you feed. The columns for moisture, smell and pests tell you when the bin is getting more than it can clear.
What should a healthy bin look like?
Most guidance describes damp but not dripping bedding, an earthy smell and busy worms. Write what you see in your own words; a run of wet, sour or fly-ridden checks is the cue to look at what is going in.
