From the page: Cardboard holds up to far more than just one more move
Idea 1
Countertop worm compost bin
Vermicomposting has existed for centuries and became a hit in urban apartments precisely because it fits in any corner. Cardboard is the worms' home and food: the cellulose fibers retain moisture and provide the carbon that balances food scraps, creating the dark, damp environment that red wigglers love.
What you need
- 2 or 3 cardboard boxes (one nesting inside the other)
- Red wiggler worms (about 250 g to start)
- Fruit peel scraps, coffee grounds, and used tea bags
- Damp soil or ready-made humus for the initial bedding
- Cardboard shredded or in damp strips
- Scissors or utility knife
- A dark cloth or the box's own lid
How to make it
-
1
Punch breathing holes in the inner box and remove any plastic or adhesive tape, because the compost bin needs ventilation and plastic releases residues that worms avoid.
-
2
Line the bottom with a layer of damp folded cardboard, creating a "bed" that holds moisture without soaking — squeeze it with your hand: one drop should come out, not a stream.
-
3
Place the damp soil with the worms inside and leave the box open for a few minutes: they flee the light and bury themselves, which confirms the environment is good.
-
4
Add the first food scraps in a half-moon shape in one corner, burying them lightly, so the worms find the food without attracting flies.
-
5
Cover everything with damp cardboard strips: this layer keeps the moisture stable and darkens the environment, imitating forest soil.
-
6
Nest the inner box inside the outer one and check once a week, always adding dry shredded cardboard when it gets too wet.
Finishing touches
In two to three months you'll have dark humus for your plants — just stack a perforated box on top and the worms migrate to the new food, leaving the finished humus below. Never add too much citrus, meat, or dairy, which unbalance the bin.
