Composting and worm farms for small backyards

You don't need a big yard to turn kitchen scraps into something useful for your garden. Here's how to choose between a compost bin and a worm farm when space is tight.
1. Compost bin or worm farm?
A compost bin breaks down a mix of food scraps and garden waste. A worm farm uses composting worms to turn scraps into worm castings and liquid. Worm farms are often compact, so they can suit courtyards and balconies.
2. Pick a spot
Both do best out of harsh sun and heavy rain. Worms don't like getting too hot, so a shady spot matters, especially in summer. Keep it close enough to the kitchen that you'll actually use it.
3. Know what goes in
Most fruit and veggie scraps, coffee grounds and torn-up paper or cardboard are common inputs. Worms usually don't like onion, citrus or garlic in large amounts. Leave out meat and dairy, which can attract pests and smell.
4. Balance greens and browns
For a compost bin, mix "greens" (food scraps, fresh clippings) with "browns" (dry leaves, shredded paper). Too wet and it smells. Too dry and it slows down. Turning it now and then helps.
5. Compare before you buy
Look at size, how easy it is to empty, whether it has a tap for worm liquid, and what it's made of. Composting worms are often sold separately, so check what's included.
6. Check with your council
Many local councils run composting programs or workshops. Check your council's website to see what's offered where you live.
