🍽️ Answers both “how much” AND “which days” — live
Tell us roughly how much your worms weigh, and we’ll build you a real feeding schedule — not just a number.
How much to add each time you feed — spread across multiple smaller feedings rather than one large one, since worms process food gradually.
Smaller colonies get fed less often (every 3-4 days); larger, established colonies can handle more frequent feeding since they process scraps faster.
A conservative-to-maximum range based on your worm weight — start near the low end and work up as you observe how quickly food disappears.
The upper limit a fully mature, well-established colony could theoretically process in a single day — useful context, not a daily target.
Uneaten food sits, goes anaerobic, and starts to smell — it's the single most common beginner mistake. If you notice food still visible after your next scheduled feeding day, skip that feeding entirely and wait until it's mostly gone before adding more.
Much safer than overfeeding — worms simply eat their existing bedding and slow their reproduction rate slightly. There's no harm in erring light while you learn your bin's rhythm.
Use the calendar as a starting rhythm, but always do a quick visual check first — if there's still food from last time, skip that feeding regardless of what the calendar says. The schedule is a guideline, not a rule.
Yes, somewhat — watery foods like melon break down fast and can be fed a bit more generously, while dense foods like potato take longer. Chopping or freezing-then-thawing scraps helps most foods break down faster regardless of type.
Gradually — re-run this calculator every few weeks as you re-estimate your worm weight. Worm populations can double every 60-90 days in good conditions, so your feeding amount should scale up steadily over months, not overnight.
Only once a colony is large and established — for smaller or newer bins, daily feeding usually outpaces how fast the worms can actually process it, leading to buildup. Stick to the suggested frequency until your colony is clearly keeping up.
