Here in NZ you can buy a good basic worm farm from The Warehouse or other similar places. It has three boxes with screen dividers in between. The bottom box is where the worm pee or run off from the castings is collected. The middle box is where the maturing castings are and the top box is the one you are filling.
|The top box - room for more!|
|The middle box - filled with beautiful, rich castings.|
My good friend Sue is moving back to the UK from whence she came a good while back. I'll miss her terribly (but I'm looking on the bright side - I'll have someone to visit!). They've been downsizing and having a clear out and I've already benefited, but this worm farm set up is one of the best things yet!
Sue's handy husband has plugged in a simple hose fitting set up to drain the worm pee. Whenever the watering can is half full, it can be topped up with water to dilute it and used to water plants and give them a boost. This eliminates the frequent heavy lifting. The worm farm needed a stand to accommodate the hose, but this could be adapted from an old table or bench.
Two farms is the perfect amount of room for our family. The chickens get bread scraps, cabbage, apple cores etc and the worms get the stuff they won't eat, like citrus, teabags, bits of paper and potato and banana peels. And I get the worm castings to spread in my garden the the worm pee to use in my pots or on anything that needs a boost!
Official worm farm guides suggest that worms don't like citrus, but mine don't seem to mind a bit. Plus I sprinkle a bit of lime in from time to time as worms prefer less acid conditions.
So if you've been contemplating a worm farm, this might give you some ideas on how to set one up effectively, or if you've got one and it's been annoying you, get down to your local hardware and buy a few hose connectors. You're plants will love you for it.
