Finished compost should be dark and crumbly with a sweet earthy smell. Generally, you shouldn't be able to identify the original materials you added to the pile — those broccoli stems and leafy greens should have "disappeared," although egg shells and woody materials can persist. You can use a wire mesh screen to sift the compost and return the larger pieces back to your compost pile.
If you only have room for one bin, harvest finished compost from the bottom of the pile and keep layering fresh material on top of the pile. Some compost bins have a door at the bottom for easy harvesting. With other bins, use a pitchfork to scoop out the actively composting material into a pile until you reach the finished compost. Fork out the finished compost into a wheel barrow. Return the active pile into your bin. This can be a bit of work, but it's a great way to turn your pile while reaping the benefit of finished compost.
No. Don't add pet waste because it can carry harmful pathogens.
You may have too much brown, carbon-rich material. try adding more greens — nitrogen rich materials, such as food waste or fresh grass clippings. Check the moisture of your pile, it may be too dry. Add water until the pile is slightly damp and turn.
Yes and no. If you are hot composting, the hot temperature of the pile will kill weed seeds. If you are more of a laid-back composter, it is best to avoid weeds that have gone to seed. In general, it is best to avoid noxious weeds in the compost pile and instead place them in your green waste cart.
A pile heats up because of the activity of the decomposers (bacteria, fungi, and bigger creatures such as sow bugs and worms), not because of the heat from the sun. It is best to place your bin out of direct sunlight so that the pile doesn't dry out too quickly.
Although meet and dairy products are compostable, you shouldn't put them in your home composting bin because they can attract flies, rodents and other pests.
Large-scale composting facilities that process the food waste from curbside collection programs are designed and managed to handle all food waste, including meat and dairy.
Check the moisture. Ants are not harmful to the compost process but can be discouraged from nesting by adding moisture and turning the pile.
The most common cause for odor and fruit flies is exposed food waste. Make certain that all food waste is covered. When adding fruit and vegetable trimmings to your pile, dig a hole in the center of the pile and mix in your food waste. Then cover with a layer of brown material (dry leaves or straw for example). If you have a fly infestation cover with dry brown materials and refrain from adding more fruit and vegetable trimmings for 3 weeks.
