What to do if compost isn’t breaking down?

If you find that your compost pile isn’t breaking down as quickly as you expected, there are a few steps you can take to remedy the situation. First, it’s important to understand why the compost might not be breaking down effectively. Typically, compost needs a balance of carbon-rich materials (such as leaves, straw, and cardboard) and nitrogen-rich materials (such as grass clippings, vegetable scraps, and coffee grounds) to decompose properly. If your compost pile lacks nitrogen, it may not heat up and break down efficiently.

One solution is to turn and water your dormant pile. By turning the compost, you introduce oxygen and mix the materials, creating an environment that is more conducive to decomposition. This helps to distribute moisture and heat evenly throughout the pile. Watering the compost ensures that it has adequate moisture, which is essential for the microorganisms responsible for decomposition to thrive. A good rule of thumb is to aim for a moisture level similar to that of a damp sponge.

If turning and watering the compost doesn’t seem to make a difference, it’s possible that the pile is lacking nitrogen-rich materials. In this case, it may be necessary to take more drastic measures. One option is to tear the whole pile apart and assess its composition. Look for an imbalance between carbon and nitrogen materials. If there is an insufficient amount of nitrogen-rich materials, such as grass clippings or vegetable scraps, it may be necessary to add more.

To give the compost pile a boost, consider incorporating nitrogen-rich additives such as manure or bloodmeal. These materials provide the necessary nitrogen to kickstart the decomposition process. Manure, whether from cows, horses, or chickens, is an excellent source of nitrogen and other nutrients that can help break down the compost faster. Bloodmeal, which is made from dried animal blood, is another effective option for increasing the nitrogen content in the pile.

Once you have added the necessary nitrogen-rich materials, pile the compost back up and ensure that it is properly aerated and moistened. Turning the pile regularly, about once a week, can help maintain a good balance of oxygen and moisture throughout the compost. Additionally, be mindful of the size of the compost pile. A larger pile tends to heat up more efficiently and decompose faster.

In my personal experience, I have encountered compost piles that were slow to break down due to a lack of nitrogen-rich materials. By adding manure and turning the pile regularly, I was able to rectify the situation and achieve a more balanced decomposition process. It’s important to be patient and persistent when dealing with compost, as it can take time for the organic materials to break down fully.

If your compost isn’t breaking down effectively, start by turning and watering the pile to promote decomposition. If that doesn’t help, assess the balance of carbon and nitrogen materials in the pile. If nitrogen is lacking, add manure or bloodmeal to provide the necessary nutrients. Remember to turn the pile regularly and maintain proper moisture levels. With time and attention, your compost should eventually break down into nutrient-rich soil amendment for your garden.
