You should generally keep the lid on your compost bin to retain heat and moisture, control pests, and manage odors, but ensure there are air holes for necessary aeration; leave the lid open only if your bin is getting too wet from rain or if it's an open pile needing airflow, otherwise, a lid or cover (like a tarp with gaps) helps regulate moisture and temperature for faster decomposition.
No compost bin needs a lid, however, a lid does aid you in controlling, better, what goes on in your pile. A lid does help control the amount of moisture in your compost, although many people have composted, successfully, for years without lids.
Compost bins often require a lid that keeps away excessive rain that can slow down the decomposition. On the other hand, these containers are usually open or come with an additional compartment at the bottom for easy compost harvesting.
Forgetting the Balance of Ingredients
Indoor composting still relies on a mix of “greens” and “browns.” Too many food scraps turn into a wet mess, while too much paper or cardboard slows the process.
Turning – or mixing – the composting material adds air, which is necessary for the composting process. If the material is too wet or becomes compacted, then composting will be slower as less air is available.
Don't:
The Bottom Line On Covering Compost
Many gardeners have composted for decades and never covered a pile. They get good compost that makes a wonderful addition to planting beds and seed starting mix. If you're building your first compost pile, it's perfectly okay to let the pile remain uncovered.
Can you compost Toilet paper rolls? Toilet paper rolls are made from cardboard, so they are compostable! As long as these rolls aren't contaminated, they're a great addition to your compost bucket.
10 things you shouldn't put in your compost (and why!)
Avoid sprouted or rotten potatoes: While you can compost potatoes, it's best to avoid sprouted or rotten ones. These can sprout in your compost pile or attract unwanted pests.
Using pee: a how-to guide. Keep in mind that urine is very high in nitrogen. You may need to pee daily, but your plants don't need your daily pee. Choose plants that need lots of nitrogen, such as corn and squash, tomatoes and cucumbers during their fruit-bearing stage, and older plants that need a boost.
Banana peels are packed with potassium, phosphorus, and calcium — nutrients that are essential for plant growth. They decompose quickly, making them a fantastic addition to your compost pile. Plus, by composting peels instead of tossing them in the trash, you help reduce landfill waste.
Bag composting
Put everything in a plastic bag, and forget about it for a few months. Again, ideally don't put anything too smelly in it, or pests will break in. Don't smell it either before it turns into compost!
Potatoes contain nutrients such as nitrogen, phosphorus, potassium, and magnesium. Composting potato peelings adds these nutrients to the pile and benefits the plants that will eventually be grown using that compost.
The 5 common mistakes in worm composting are overfeeding, which causes smells and pests; incorrect moisture, making it too wet (anaerobic) or dry (dehydration); wrong food choices, avoiding meat/dairy/oils; poor ventilation/temperature, leading to suffocation or extreme heat; and ignoring bedding balance, failing to mix carbon ("browns") and nitrogen ("greens") for proper bedding. These errors create unhealthy environments, stressing or killing worms, and leading to system failure.
While you can keep your outdoor compost bin in direct sunlight, it's recommended to place it somewhere in the shade. While a nice sunny spot can make your compost decompose faster, it can also severely dry it out (via Milorganite).
7 mistakes that could ruin your compost
No Dairy and Eggs
The resulting smell of rotting milk or eggs will attract unwanted visitors. Eggshells, on the other hand, do provide valuable calcium to the resulting compost. It's best to rinse and dry the eggshells before reducing them to a fine grind or powder.
Certain citrus, most notably the Sour or Seville Orange, will not break down if the peel is perfectly intact. My guess is that the oils and acids of the rind prevent the entry of composting micro-organisms.
Paper cartons are compostable!
If you have a home compost, rip up your paper egg carton into small pieces and add it in! These cartons are made from paperboard, which works as a “brown”, carbon material to help the pile break down more quickly.
Eating any food while on the toilet is forbidden. After defecating, the anus must be washed with water using the left hand, or an odd number of smooth stones or pebbles called jamrah or hijaarah (Sahih Al-Bukhari 161, Book 4, Hadith 27). Many jurists agree that toilet paper suffices in place of these stones.
Yes, you can use the compost toilet when you have diarrhea. If that's the case, we recommend that you change the bags more often and add more cover material than usual to help bind the extra liquid. If the diarrhea is due to an illness, do not compost the solid waste.
Without proper aeration, microbial activity will be limited since most of microorganisms participating in decomposition are aerobic (oxygen loving). With limited microbial activity, composting would be slow. With adequate aeration, the temperature of pile rises quickly hours after composting started.
Reduce turning frequency or stop turning when temperatures dip below freezing for sustained periods of time. Add a layer of insulation on top of the compost pile. This could include finished compost, compost covers, woodchips, or other dry feedstock like straw. Insulate the compost bin.
