Question
I get an accumulation of grass clippings thru the lawn care season. I have made a bin out of steel fence posts and chain link fencing. It works great but it doesn't make compost.

I'm pretty sure from my research that it's because I use all grass clipings.

I know I need to mix in some soil and some brown carbons? such as leaves, or broke down wood. My problem is access to such materials. I really don't have a stock pile of dirt to use but I could probaly find someone to give me some brown carbons.

Could I use straw to mix in with the fresh grass clipings to make compost?

Any info is greatly appreciated.

Answer
Hello Tim

Yes you have answered you own questions rather well.

First, yes you may add Straw as a Carbon filler. Next if Carbon matter is a problem, just save your Leaves from the Fall, put them in a Bag with enough holes in it to get some
air into it, and mix it in with the grass clippings in the summer.

6 good size bags of Leaves should be enough for you, if you have an average size lawn.

Your Carbon to Nitrogen Ratio should be about 25-1 for Ideal conditions for Compost, that should equate to about 4-6" of Leaves for every 1" of Grass. Layer this starting with Grass Clippings, then Leaves, then 1" of regular garden soil. Garden Soil is your activator, and spark for the process to commence. No need to buy Activators at the Garden Centers, they are a waste of money. Water each Layer well, but do not Soak. Stack to a Height of 3-5 Feet. When you sense Heat, the process has begun turn the Whole Pile over until fully Decomposed. How long is that? It depends on many factors. Locate the Pile in Direct Sun, and it should be Decomposed in 4-6 weeks.


The Best of Luck
