The ideal moisture content for composting is between 40 and 60 percent by weight. Microbe growth is restrained under low-humidity conditions.

There is a risk of the process becoming anaerobic and odorous at greater concentrations. It’s a good idea to consider the moisture content of your compost elements when selecting and combining them.

How Damp should a Compost Pile be?

For microorganisms to thrive, the surrounding air must be damp. Materials for composting should have a moisture content of 40-60%.

Anaerobic conditions can develop when water fills the pores required for air passage due to excessive moisture. The pace of breakdown is slowed if moisture levels are low.


Is Compost better Wet or Dry?

Dry conditions in a compost bin prevent the growth of the bacteria and fungi necessary for the composting process, thereby halting the decomposition of the compost.

On the other hand, it is possible for a compost pile to become too wet. Dig your compost pile all the way out, turn the materials to distribute the moisture, and then re-stack. A 40-60% moisture content by weight is desirable for composting.


How To Make it Perfect?

To create high-quality compost, you must combine equal parts nitrogen- and carbon-rich ingredients. Green waste products like grass clippings are a good source of nitrogen.

Woody stems and cardboard are brown. Thus they provide the carbon. In order to balance out the green stuff, you’ll need to bring brown stuff in equal measure.

In order to balance out the green material, you’ll need to bring in brown material in equal measure. If you’re going to be using woody stems, shred them first, so they decompose faster.


Common Mistakes You Need to Avoid

If you mess up the composting process even once, you may be in for a tough time. The following are some of the most typical blunders that people make when composting.


Using One Pile/Bin

In order to add additional material to the second bin chamber or pile while the first batch matures, having at least two piles or a double-chamber bin is recommended.


Imbalance of Browns and Greens

Inexperienced composters commonly misstep by not using enough brown and enough green plant material. Mixing three parts brown with one part green is the general norm. If there’s too much vegetation, it will rot and stink.

Furthermore, decomposition will be slowed by an abundance of brown. It doesn’t have to be exact, but for every green kitchen waste bucket you put, you should ideally add three brown ones of the same size.


Using the Wrong Materials

Avoid putting any scraps from foods that contain animals, such as meat, fish, fatty food, or dairy products, in your trash or pile. In addition to attracting vermin like cockroaches and rats, the odor produced by their decay is unpleasant.


Too Little/Much Water

Decomposition can’t happen without water. However, if the pile becomes too wet, the bacteria won’t be able to decompose the material because they won’t have enough oxygen.


Leaving the Compost Pile Open

If you want to build your own compost container, just place a sheet of plywood on top. An open compost pile on the ground can be protected from rain, and unwanted visitors with a tarp stretched over a crude wooden frame.

Keep a few inches of air space between the top of the pile and the cover at all times.


How Can You Tell If It’s Too Dry?

By glancing at the pile, you can tell whether it is too dry; if there is no heat and no signs of organic material decomposition, then the pile is too dry.


Final Thoughts on How Wet Should Compost Be

Although composting isn’t the most difficult thing in the world, some common mistakes can still be made, especially for first-timers.

However, if you keep your browns and greens balanced, keep multiple bins, and cover them up, then there should be little to worry about.
