Q: Can I add cooked food waste to my worm composter?

I would avoid this – first of all there’s the trudge to the bottom of the garden but also this sort of waste has a tendency to attract pests if anything is going to. The best methods for kitchen waste are Worm Composting or Bokashi and for cooked waste Bokashi is the most flexible - the Japanese fermentation method is fantastic for all sorts of waste and can deal with bulk amounts in one go (unlike a worm composter).

Question 1

How do I encourage worms in my garden?

Accepted Answer

If you can get a healthy population of worms in your soil they will make you an ongoing supply of topsoil so to encourage them to breed avoid disturbing the soil where you can and feed them!

You can add garden worms as well of course but also making your own worm compost and adding this to the soil will also encourage a natural increase in your worm population.

Question 2

Can I Add Cardboard To My Wormery?

Accepted Answer

Cardboard is great for your worm composter (as is a sprinkling of lime mix) A ratio of 25-30% volume of cardboard or equivalent will ensure speedier worm composting. Avoid the really shiny boxes like soap powder and go for newsprint, egg boxes etc.

Question 3

What shouldn't I feed to my worms?

Accepted Answer

Avoid grass clippings (as they heat up), glossy printed paper and cardboard (lots of chemicals) Non Biodegradables (of course), Dog and Cat droppings (can carry human pathogens) and raw meat.

Question 4

Why use worms to compost.

Accepted Answer

In the UK it's estimated that households throw away about a third of the food they buy. Around half of the 6.7 million tonnes of food thrown in the bin each year is edible and the rest comprises waste such as veg peelings and food scraps.

All this waste then gets transported to landfill sites around the UK. These sites are nearly full and account for a large percentage of the greenhouse gasses that pollute our atmosphere.

Even if they centrally compost the waste it is still a huge waste to transport waste and compost back and forth from people's houses back to their gardens. Worms are efficient at turning all organic material into a valuable soil fertiliser called vermicompost.

Question 5

What should I do once I have filled one tray in my worm composting kit?

Accepted Answer

Once you have filled one tray in your worm composting kit, there are a few things you can do to continue the composting process:

Add another tray: If your worm composting kit has multiple trays, you can add another tray on top of the filled one. The worms will eventually migrate up to the new tray and begin processing the new food. NB: Check for gaps between the trays as sometimes as the worms work on the waste it reduces in volume and sinks so that it’s more difficult for the worms to move up. If this happens just add more waste into the gap.

Question 6

What pH level should my wormery be at?

Accepted Answer

A well maintained worm bin should have a pH measurement between 6.0 and 7.0, which is perfect for many types of composting worms. Most can handle pH conditions up to 8.0, but its always best to play it safe and try to maintain a pH in the 6.0-7.0 range. The easiest way to do this is to add a handful of lime mix into your kit every couple of weeks. Don't worry about over liming as your lime mix is a mix of calcified lime and fibre rather than conventional garden lime which is too strong.

Basically to ensure your kit isn't too acidic look out for the signs of acidity - these are flies being attracted to the kit, a putrid smell, a really wet kit, or sometimes even swollen bits all over your worms (which is protein poisoning). If you see or smell any of these issues just add a few more handfuls of lime mix - add crushed egg shells for a similar affect and all will be well.

Question 8

What Do Worms Need To Survive And Thrive?

Accepted Answer

Basically worms need food, air, and moisture – all of which are pretty easy to provide. Once you’ve understood that your wormery is not a waste disposal machine but a living, working ecosystem you will find it provides a service as well as providing some great worm compost and liquid feed.

Question 9

I'm looking for extra spare trays for my Can-O-Worms - do you have some?

Accepted Answer

I’m sorry we stopped stocking Can-O-Worms in 2013 so have sold out several of spare trays (although we still stock moisture mats, lime mix, worm treat and complete rescue kits. The best way to source hardware parts including trays is usually ebay or gumtree.

Question 10

How do I harvest my worm compost without the worms?

Accepted Answer

There are a few methods to harvest worm compost without the worms:

The "bottom tray" method: This method involves removing the bottom tray of the wormery and placing it on top of the top tray and removing the lid. This will allow the worms to migrate downwards. The compost in the bottom tray can then be harvested without disturbing the worms.
The "windrow" method: This method involves creating a "windrow" (a long, narrow pile) of the worm compost on top of a piece of plastic sheeting. The worms will migrate to one end of the windrow, leaving the compost at the other end ready for harvest.
The "casting" method: This method involves allowing the worms to work the compost for a longer period of time, until the castings (the worm manure) have dropped to the bottom of the tray, where they can be harvested without worms.
The "screen" method: This method involves using a screen or sifter to separate the compost from the worms. The worms are placed in a new container with fresh bedding and food scraps, while the compost can be collected and used.
