Our Worm Farm
Composting worm farm
Imagine the amount of food scraps that the park generates over one year, particularly given how many people stay with us over the Christmas/New Year period. We have found a way of recycling our waste by saving up certain food and paper scraps and feeding them to our worms who work their magic on them.
How does a worm farm work?
The natural bacteria in our environment and little fruit flies help to start the process. The worms start by eating all the juicy pieces, leaving all the hard to eat bits for the bacteria to keep composting. Worms eat the food once it is nice and rotten, that’s how they like it!
As the worms and bacteria eat the waste, the water inside it is released and drains to the bottom. It is called worm tea (‘pee’) because of its colour.
The worm castings (‘poo’) look like soil and contain an amazing amount of nutrients and trace elements. These castings are 5 times richer in nitrogen, 7 times richer in phosphates and 11 times richer in potash than average topsoil! These castings are very valuable to plants, and more suitable than regular fertilizers as they increase a plants resistance to pests and disease.
Worms really like:
- Most fruit & vegetable scraps
- Teabags & leaves
- Coffee grounds and filters
- Bread scraps
- Paper towels
- Biscuit crumbs and cake
Worms are fussy eaters, they don’t like:
Meat, fish, dairy products, lots of garden waste, shiny paper, citrus or acidic fruit, onions (who would!), garlic, or spicy food.
Benefits to worm farming
Kitchen and garden rubbish is great for compost but not so good for putting in landfill. As it breaks down it produces a nasty greenhouse gas called methane. It also produces liquid known as leachate that can pollute our waterways.
Other ways we dispose of food waste also cause problems – burning waste causes air pollution, and in-sink waste disposal units put pressure on our sewer systems and treatment plants.
Worm farms avoid all this and provide the added benefit of producing a nutrient-rich compost-like substance (worm castings) and ‘worm juice’ that can then be used in our gardens – saves us having to buy extra supplements to help our garden looking beautiful and our herb garden lush!
Make your own worm farm
There are many easy ways to make your own worm farm. From raised old baths to compact units made from recycled products that are even suitable for indoors. Ours is a commercial sized unit from Worms R Us.
- A worm has 5 hearts, no eyes, no arms and no legs!
- Worms breathe through their skin
- Worms can eat their body weight in food each day
- If everyone had their own worm farm we’d each save 1 tonne of compostable waste going to landfill each year
