Worm farming is a fun way to turn your organic waste, like kitchen scraps, into rich fertiliser for your garden in the form of worm castings and worm tea. A fun activity or a great way for schools and businesses to recycle scraps!
SETTING UP YOUR WORM FARM
1. Choose a shady position for your worm farm and ensure it is easily accessible to feed your scraps straight to the worms.
2. You will need about 1000 (250g) worms to get started, and they can be purchased from a garden centre or DIY store, or if you know someone with a worm farm they may be willing to share!
3. Next you need some bedding material for your worm farm. Our worm farm kits supply this.
4. Add some compost to help get your worm farm started.
5. Add the worms to the top tray and let them settle in.
FEEDING YOUR WORMS
6. Allow your worms a few days to settle into their new home then add a handful of food scraps to the surface area. Your compost worms will eat raw and cooked food and vegetable scraps from your kitchen. Coffee grinds, tea bags, dust from vacuum cleaners and soaked egg cartons can also be added. Chopping up scraps, or even blending them, will make it easier for the worms to eat your leftovers, quickly!
7. Avoid feeding meat, dairy products or bread as these can attract unwanted pests. Onions, citrus peel and tomatoes are very acidic, so are generally not added, however, small amounts can be used as long as they are well mixed in with other food.
8. As a rule of thumb worms eat approximately ½ their body weight in food, so if you start with 250g of worms, you can feed them approximately 125g of food a day.
9. Place a worm blanket or wool blanket on top of the worms to keep the worm farm moist and dark.
USING WORM CASTINGS AND WORM TEA
10. Our worm farms have a tap so you can collect the worm tea in your watering can as it is produced. Water it down to the colour of weak tea before using on your garden.
11. While you can collect and use your worm tea at anytime, collecting the castings (or worm poo), will depend on how many worms you have and how active they are. Generally, once the worms have processed the food scraps in the lower tray, you can remove this tray to use the castings in your garden, or collect small amounts to use in potting mix or seed raising mix at other times.
