What’s better, a compost pile or a worm farm?
It depends on how much material you have. An effective hot compost pile needs to be at least one metre by one metre at the base (even better if it’s 1.5 metres) and the same in height. You can store your garden waste until you have gathered enough material to make a decent-sized pile. If your material is more of a small but continuous stream of kitchen and garden scraps, then you might choose to keep a worm farm instead. Worm castings (or vermicast) can be used in a similar way to compost to fertilise your garden and diluted worm wee makes an excellent liquid tonic.
