My Compost Is Too Hot What To Do About Overheated Compost Piles

The key to managing the heat level is to make sure there is introduction of oxygen and moisture to all parts of the compost. You also need the right balance of carbon and nitrogen materials. Compost is too hot often with too much nitrogen. The proper mix is 25 to 30 parts carbon to one part nitrogen.

What do I do if my compost is too hot?

Compost managers strive to keep the compost below about 65°C because hotter temperatures cause the beneficial microbes to die off. If the pile gets too hot, turning or aerating will help to dissipate the heat.

How do you cool down hot compost?

To cool off a pile, give it a few turns with a pitch fork to allow heat to escape. If after a few hours temperatures start to creep back up, check your ratios of green to brown matter. Add more dried leaves to slow down the bacteria. If you had to set a target temperature for your compost pile it would be 150°F.

How long do compost piles stay hot?

A good, hot pile will reach at least 130°F (54°C) and stay there for two to four days. When the temperature drops back down to about 100°, turn the pile — and watch the temperature soar.

At what temperature does compost combust?

Compost temperatures must reach 300°F to 400°F (150°C to 200°C) for spontaneous combustion of materials to take place.

How often should I turn my compost pile?

By turning more frequently (about every 2-4 weeks), you will produce compost more quickly. Waiting at least two weeks allows the center of the pile to heat up and promotes maximum bacterial activity. The average composter turns the pile every 4-5 weeks.

Can a compost pile get too hot?

Excessive temperatures in compost can cause a spontaneous combustion, but this is very rare even among over-heated compost piles. Properly aerated and moist compost piles, no matter how hot, are not dangerous. Even hot compost bins that are fairly enclosed will not catch fire if they are tumbled and kept moist.

What will happen if you left the compost too long?

If you leave compost in the pile, in a bag or bin too long, it can still be good to use for years as long as you control moisture levels, cover it and store it in a dry place. But gradually it will break down, nutrients will leach and compost can start to rot as well as it can get contaminated with fungus.

Why is my Compost not heating up?

If the compost pile is not heating up, then the pile is too wet or too dry or there is not enough green material (or nitrogen) present. If too wet, the material should be spread out to dry. If too dry, add moisture to make it “spongy”. ... Good luck on your compost.

Why is my compost not breaking down?

A: Here are the top 4 reasons for a compost pile not breaking down: Pile is too Dry: Add water to the pile. For tips on getting the moisture content right see the measuring moisture section. ... Too little Air: Many of the organisms that break down your compost pile need air to live.

Can I keep adding to my compost pile?

ANSWER: Yes, using the cold, or passive composting method, also known as the add-as-you-go method, you can continue to add kitchen waste to your compost pile gradually over time.

Should I cover my compost pile?

In most cases, a compost pile does not need a cover. ... A cover can limit airflow and water, interfering with the composting process. You should definitely cover finished compost. Otherwise, if it's exposed to the elements, the compost will break down further and lose nutrients as they leach into the surrounding soil.

Can you compost in a pile?

If you have too many leaves to incorporate into the compost bin, you can simply compost the pile of leaves by itself. Locate the pile where drainage is adequate; a shaded area will help keep the pile from drying out. The leaf pile should be at least 4′ in diameter and 3′ in height.

Why does a pile of grass clippings get hot?

Grass clippings and yard waste produce heat. This happens as a result of microscopic bacteria and fungi feeding on moist grass clippings. ... The bigger the pile, the more heat is trapped and the hotter the pile temperature.

When should I turn my compost hot?

The temperature will depend on moisture levels, the size of your organic matter and the size of your pile. Once the temperature cools to below 43 degrees Celsius (110 degrees Fahrenheit), which is usually between four and seven days, you will need to turn over the organic matter to introduce oxygen.

What happens if you don't turn your compost?

Not turning the compost will cause anaerobic bacteria to become dominant and slow decomposition down. Turning the compost adds oxygen and helps break stuff apart. The main drawback to having anaerobic bacteria it that they kinda smell bad.

How can I speed up my compost pile?

Turning the pile frequently allows more oxygen to the microorganisms that are creating your compost, which in turn accelerates decomposition. Aerating it every couple of days will create compost faster than aerating it weekly. Water the pile in dry weather to keep it damp, but not soggy.

How do you maintain a compost pile?

6. Maintain Your Compost Bin.

How long does it take for compost to break down?

Depending on the size of your compost pile, what you put in it, and how you tend to it, this process can take three months to two years. With a Compost Aerator, it's easier to add air to the pile. Aeration gives oxygen-hungry microbes what they need to break down materials faster.

How long does Finished compost last?

Both commercial and homemade compost can last for more than one year when sealed, but the volume of compost and microbiological activity may diminish significantly after the first year.
