@cottiac Hi - the worm farms are really useful - you can put any old or leftover food or peels etc into their box and their actually decompose it. There are hundreds of them in the box so they produce lots of worm poo. When water passes through the farm you can then collect quite concentrated "worm juice". You dilute this 1:10 and use it as a very effective fertilizer. It's a win-win situation - and they are cute.
