Worm composting at home — turn kitchen scraps into rich castings
Practical vermicomposting guides — red wigglers, worm bins, feeding, and castings.
What temperature do worms like? Red wigglers like 55 to 77°F, and they do their best work between 60 and 70°F. In that range they eat well, breed steadily, and turn scraps into castings in about 60 to 90 days. Below 55°F they slow down, and above 77°F they get stressed — and a hot […]
How much worm castings per plant? For most garden plants, a handful — about 1/4 to 1/2 cup — mixed into the soil around each plant. For a bed, spread a thin 1/4-inch layer. For a houseplant in a 6-inch pot, 1 to 2 tablespoons on top. Castings are gentle and will not burn plants. […]
A worm bin for apartments works in a space as small as a kitchen cupboard — no garden, balcony, or garage needed. A 10-gallon tote fits under the sink, in a closet, or beside the fridge, and turns kitchen scraps into castings for houseplants and pots. Setup costs under $30, plus $20 to $40 for […]
How long do red wigglers live? In a home worm bin, about 1 to 2 years. In ideal conditions — steady temperature, damp bedding, regular food — some live up to 4 years. In a bad bin they may last only a few months. What matters most is the population: a healthy bin replaces its […]
What is vermicompost? It is compost made by worms. Red wigglers eat kitchen scraps and bedding, and what comes out the other end is vermicompost — dark, crumbly, earthy-smelling castings that feed garden soil. It is finished compost, made slowly, in a bin, by worms. Vermicompost, worm castings, and worm compost are used as if […]
Why are my worms escaping? Usually, something in the bin is wrong — too wet, too dry, too hot, too cold, or too acidic. Worms do not leave a good bin. The cause is usually one of four things; find it in ten minutes. Red wigglers love damp, dark bedding and steady food. When they […]
How to make worm tea? Soak 1 cup of finished worm castings in 1 gallon of water for 24 hours, stir a few times, strain out the solids, and use it the same day. Dilute it 1 part tea to 1 part water, and pour it on the soil around your plants — never on […]
Stacked tray vs tote worm bin — which should you buy? Start with a tote. A DIY tote bin costs under $30, holds 1 to 2 lb of red wigglers, and teaches you the whole system. A stacked tray bin costs $80 to $150, but it makes harvesting much easier, because the worms move up […]
Worm bin in winter comes down to one move: bring the bin inside before the first freeze. Red wigglers thrive at 55 to 77°F, slow down below 55°F, and stop eating below 50°F. A bin left outside in freezing weather freezes solid, and frozen worms do not recover Winter kills more worm bins than any […]
Can worms eat coffee grounds? Yes — red wigglers eat used coffee grounds happily, and the grounds even help the bin. But coffee is a seasoning, not a meal. For a settled bin with 1 lb of worms, about 1,000 worms, the safe amount is about 1 tablespoon of grounds per feeding, mixed into the […]
