Three Steps to Making a Compost Pile and a Confession

A compost pile is often built up in a specific way to be effective and here are a few of the guidelines.

The first is that the minimum size for effective “hot” composting is 4 feet by 4 feet by 4 feet tall. Anything smaller than this will not heat up enough to kill off bacteria or weed seeds. Smaller piles will “rot” down or produce what is sometimes called “cold” compost.

This obviously creates a bit of a problem in that few of us have enough organic material to create this large a pile with our day to day refuse. I note the exception to this is our leaf collections in the spring will often fill this size of container quite nicely.

As an aside, I note the feral cats on the island consider our topless compost bin as their personal feeding station. I really do not have much of a problem with this, even if the odd raccoon comes and visits as well, and I look at it as just another method of recycling.

Step One: Building A Super Compost Pile

A compost pile then is built up of carbon and nitrogen sources in the ratio of 30 percent nitrogen to 70 percent carbon. Some resources tell you that “green” organic sources such as grass clippings or lettuce leaves are “green” while other material such as leaves are “brown”.

Dare I confess, I seldom worry about this but find if I’m mostly using house scraps, it all breaks down just fine. But that’s what the manuals all say.

Bacteria & Fungi in Your Compost Pile

This usually works this way because bacteria break down the nitrogen or “green” sources while fungi break down the cellulose or “brown” organic matter. And we need both to create good compost as they work in tandem in breaking down organic matter.

When I was building large bins at the farm, I would usually start with something quite coarse and fibrous at the bottom of the pile. I usually used straw and leaves down there if possible. I’d build a foot thick layer.

Then I’d add a 6-inch to foot thick layer of green material whether it was household waste or barn manure.

Then a few inches of garden soil would be spread equally over this mix. The garden soil provided the necessary starter bacteria and fungi to get the pile composting.

This would be repeated until the 4×4 bin was full.

I’d water it and then walk away. The bin would start to heat up and I’d simply let it do its thing.

Step Two: Turning the Compost Pile

The compost pile would invariably heat up and if I waited a month or so, it would start to cool down again.

As soon as it started cooling down (use your hand as a guide – when the internal temperature lowers down to where you can put your hand in there comfortably) you can turn over your compost, mixing it up and getting it ready for a second heat cycle.

It will heat up again.

At this point, you’re going to notice your compost pile has shrunk considerably. This is fine and expected.

Step Three: Really? I Don’t Like That Much Work

Some gardeners repeat step two – turning the pile- again. I never did because I was too lazy and was happy to let the compost work itself. I was happy with the product I produced and the plants never seemed to complain.

Doug’s Summary Notes and Confession

Having said all that, I have a confession to make. While I used to do all of this stuff, now the bulk of the house produce is simply tossed onto the top of a compost bin of the correct size and allowed to sit and freeze over the winter.

The spring and fall cleanup debris was used to top up the bin and get it to the right amount of material for composting but I do not spend the time or energy to turn it.

The compost produced is fine without the turning although it takes a little longer to make.

I now only have one very large bin (about 10×4 feet) and keep filling as it settles. When it doesn’t settle anymore, I toss the top uncomposted layer from one onto the other and dig out the compost.

So while you will read the recommendations to do all this turning work, it really isn’t necessary on the home scale unless you really need the heat to kill off weed seed.

In my relaxed way, I’m not a role model for industriousness and politically correct composting but it all gets done. The cats are still fed and we still recycle and produce compost. It all seems to work out.
