How to Fix a Wet Compost

First try adding more brown matter and less green matter and additionally aerate your compost by stirring it often. You can also try improving water drainage in your compost by making the holes in the bottom larger and in worst case scenario, you can empty the contents of your compost onto the ground to let them dry.


Depending on where you live and how open you leave your compost, your compost could get very dry and thus it is important to regularly water your compost so it is about as moist as a wrung out sponge. However, your compost could easily gather lots of water especially if you do not have a proper water drainage system in the bottom of your compost bin. Too much water can attract maggots and possibly even ruin your entire compost so today we are going to look at a few ways you can fix thix very problem.

Add More Brown Matter

Brown, carbon-rich matter such as cardboard or paper are very good at absorbing liquids and so adding dry brown matter can help absorb some of this moisture. Green matter also contains a decent amount of moisture so adding less green and more brown, will also help dry your compost.

Aerate your Compost

Another reason your compost is very moist could be because your compost is very dense and does not have enough air incorporated into it. Be sure to regularly mix your compost in order to help aerate it. You can also keep the top of your bin open so not only does air enter the compost, but the compost also dries quicker.

Improve Water Drainage

If you have noticed that the majority of the water in your compost is collecting at the bottom, it could be that your bin is not draining enough water from the bottom. Make sure your water drainage holes in the bottom are large enough for water to exit through and also make sure the holes are not getting blocked by anything.

Worst case scenario

If none of the above worked for you then you may want to look into emptying you entire compost bin onto to ground, spreading everything out, and letting the compost dry. Of course, this would be a very long and grueling process so please try all the above tips before you do this.


While a soggy compost may not be a problem itself, it can lead to other problems, such as maggots, which could be more serious so it is good to fix the problem before others begin. Please let us know what you think about our solutions and if you have any questions about anything. Happy Composting!
