Using finished compost or potting mix add it in each time you feed the worms OR take out the top layer of food and worms and add in enough potting mix or compost to bring the level back up. Don't bury the food in the worm farm, it needs to stay near the top with the worms.
Make sure that all food is buried at least 1 inch deep. Cut the food up small or use a food processor so the worms can work through it faster. Remove large chunks of food and any malodorous items.
Bedding should always be about 2 to 3 inches thick above food and worms.
Rotting food scraps not only smell, but also interfere with the lifecycle of the worms and the operation of the bin. Rotting food is anaerobic – or oxygen deprived. Because worms breathe through their skin, anaerobic conditions prevent the worms from breathing properly, and may cause them to die.
The molds that form on most vegetables are usually OK, but the molds on some fruit and bread can be problematic. If you're in doubt, try a small amount first and see if the worms are bothered by it. If not, then it's probably OK to use it, otherwise, you should put them into your backyard bin instead.
Banana peels are an excellent worm food.
There should always be a higher carbon to nitrogen ratio (C:N) contained in the worm bin. For worm composting, conditions are generally ideal with a carbon-to-nitrogen (C:N) ratio of between 20:1 and 35:1. Always remember, you can never add too much worm bedding on top.
Once every week, pour about five litres of fresh water into the Top Working Tray, which will flood down through the lower trays, ensuring the entire worm farm remains very moist. The sudden 'flood' will not harm the worms.
Worms can live for 4 weeks without fresh food. Put damp newspaper in the worm farm and leave in a cool location.
Paper, cardboard, and more paper.
Rip up old envelopes, receipts, toilet rolls, egg cartons, and non-glossy advertising materials and add to the scraps to your kitchen caddy, as well as adding shredded newspaper and cardboard to your worm farm.
Grass clippings are a great addition to a traditional compost pile and worms will eat these as well in their natural setting, but in your vermicomposting system, they will heat up the soil and can kill all of your worms.
Over feeding is one of the most common causes of worm farm problems. We understand that you might be eager to get your worm farm churning through as much of your waste as possible, but too much waste can cause the environment to become too acidic, damp and anaerobic – all things worms don't enjoy!
So in order to keep a compost bin healthy, you need to mix and turn your compost to aerate it and allow oxygen to reach down the deep unreachable places. The aeration not only provides oxygen for the good bacteria, but it also kills off the anaerobic bacteria since they can't survive with oxygen.
It is also important to add a bit of “grit” to the worm farm every now and again. Just a small handful of dirt, sand or soil will do the trick. The grit will help the worms digest their food.
What can I compost in a worm farm? Grains, cooked or uncooked (rice, oats, barley, wheat, etc.) The smaller the pieces, the quicker they'll break down in the compost pile. Be sure to cut cores in half and break down the pumpkin you forgot to eat.
Worms will eat anything that was once living, Leftover vegetable scraps, fruit and vegetable peelings. Tea leaves / bags and coffee grounds.
Foods that Composting Worms Love
They will happily digest a wide variety of organic plant material into nutrient rich worm castings. I put old lettuce in there, rotten vegetables, potato peels, fruit, grass clipping, and leaves, just to name a few. They especially love the fruit.
Worm blankets need to be watered whenever you feed the worms. So long as the bedding has the consistency of a wrung-out sponge, you are doing it right.
Earthworms like moist soil. They can survive in dry soils but they are not active. However if the drought is severe, they will die. In dry conditions, they can burrow deep into the soil to 1 metre, tie themselves in a knot, secrete a coating of mucous about themselves which dries and helps prevent water loss.
Composting worms can absolutely be fed with crushed shells from eggs. You should know that compost worms will eat just about anything that's organic (all except meat, seafood, poultry, dairy, oily, or spicy stuff).
Worms like to eat most vegetable scraps (except raw potatoes and peelings) they love fruit especially melon, pineapple and apple peels (they don't like citrus), they enjoy herbs (but don't like strong flavours like chilli, onion and garlic). Worms will also eat soaked and ripped paper, hair, tea bags and crushed shell.
Worms can't digest meat proteins or lactose, so no dairy products either, like milk or cheese. While worms do like egg shells, the egg cannot go in the bin.
