Yes, you should generally have a lid on a compost bin to manage moisture (prevent it from getting too wet in rain or too dry in sun), keep pests out, retain heat for faster decomposition, and control odors, though some prefer open systems for better airflow or to let in rain; it depends on your climate, composting method, and goals. A lid helps regulate the essential air, water, and material balance, especially if using a contained system.
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.
Covered bins and heaps allow waste to heat up quickly and compost faster. A lid also keeps out heavy winter rains which can chill or overly wet your compost heap. Although garden waste does eventually compost in a heap, a bin is much more efficient. Even better, use two bins so one can 'cook' while the other fills.
Home compost piles that are well constructed and maintained properly should not attract pests or rodents. If using a bin, it is important to reinforce the bin with a lid and potentially a floor. There should be no holes or gaps in your bin that are larger than ¼ inch.
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.
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.
Breaking Down Composting and Understanding the Basics
However, compost can only effectively improve soil quality if the organic stream remains clean. When non-compostable materials, such as conventional plastics, glass, metals, and produce stickers end up in the compost mix, they can easily derail the entire process.
Don't:
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.
Compost bins often require a lid that keeps away excessive rain that can slow down the decomposition.
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).
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.
Toptex Protection Fabric offer the perfect protection cover for compost, logs, wood chippings and bark. The toptex protection cover is designed to shed water, while also being breathable. The fabric cover is Non-woven, decay resistant fabric produced with 100% UV-stabilised propylene.
There is no need to turn the compost pile in the winter months, as doing so will only result in heat loss in the interior of the pile. This can slow the decomposition process further. Instead, wait to turn the pile in the spring once it is completely thawed.
7 mistakes that could ruin your compost
Spread several inches of compost on top of the existing bed, then till it into the soil in the springtime. Put a handful of compost in each hole when you're planting. Once plants begin to grow quickly, you can add a half-inch layer of compost around the base of the plants.
Urine contains important nutrients for plant growth, including carbon, phosphorous, potassium and nitrogen, and when handled properly, it makes a darn fine plant food.
Paper towel and toilet paper rolls can be recycled or composted. Toilet paper and paper towels cannot be recycled and go in the compost cart.
You should not compost onions, garlic, and citrus peels in large amounts (they're too acidic/repel worms), diseased plants (spreads illness), Black Walnut tree debris (toxic juglone), and any vegetables cooked with oils, fats, dairy, or meat, as these attract pests and disrupt the balance, but many vegetable scraps like peels, stalks, and leaves are great for compost.
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.
Some things, like grass cuttings and weeds, rot quickly. They work as 'activators', getting the composting started. Older and tougher plant material is slower to rot, but gives body to it, and usually will make up the bulk of your compost heap.
What weeds shouldn't you compost?
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.
