Making Compost in Trash Cans is Slow

Q. I’m composting in
plastic trash cans with holes. It’s taking a very long time to make compost
despite adding carbon to my grass clippings and kitchen waste. I water and turn
it every few days. What am I doing wrong? 
A. There could be several
reasons why. 

Large Volumes Perform Better

Perhaps the volume of compost is too small. If the amount of
compost is too small, it will never produce enough heat on its own. If the air
temperature is cold and the compost pile small, the composting process will be
very slow.

Wind

            Maybe it’s too windy. Composting is difficult in areas
where there is significant wind or too much sun. Compost develops better in
shady areas of the yard without wind.

Nitrogen

            The compost ingredients might not be high enough in
nitrogen. Compost ingredients are divided into two categories; “brown”
ingredients which are loaded with carbon and “green” ingredients which are
loaded with nitrogen. Compost should have significant amounts of “green”
ingredients or use animal manure.

Too Dry or 
        The compost may be too dry or too wet. Compost
needs to be moist but not sopping wet. Compost is like a living organism; it
needs air to “breathe” and moisture.
            Microorganisms are needed in the mix. I reserve a small
amount of compost from the previous mix to act as a “starter” for the new mix.
Or I will put in a couple of pounds of garden soil just for the microorganisms.
