ᐅ How can I speed up the decomposition of my compost?

Hi,
it seems like we are doing something wrong with our compost. About three years ago, we had a lot of grass clippings and piled them all up. Now, when we wanted to spread it as soil, it turned out to be a slimy, tar-like mass with grass still visible inside. We also used a rapid composter, but it seems to me like a complete scam.
Is there any trick to help the green material decompose faster?

A pile!

Dig up the pile. At the bottom is the new topsoil. Remove the topsoil and put it onto the garden beds. Put the rest back on top, but during this process, it gets “reshuffled,” “mixed up,” or whatever you want to call it. It starts as a pile and ends up just a pile again.

We didn’t even have the pile directly on soil, but on a paved surface. Inside a wooden frame, with a stainless steel grid underneath. This prevents too much moisture from accumulating in case of heavy rain. The wooden frame could be opened at the front for this process. It was simple and always worked perfectly.

Try planting a zucchini or cucumber directly in such a pile! You’ll be able to drown your neighbors with all the long vegetables ;-).

Well, that’s what we had hoped for too. But instead of topsoil, we got this tar-like slime. And by slime, I really mean slime. The texture is somewhat like fresh dog poop, and it almost smells the same. It’s difficult to spread over the beds. 😉

And it’s still not finished.

Grass alone won’t work. But now you know. I would start the compost pile again and practice patience. If started now and enriched with worms, good humus could be available in a year.

Mmmh, we have plenty of tasty worms in the garden. I wonder if they find it amusing when we relocate them into this slime? 😉

How much is left? Do you have other materials (like branch trimmings ...) to mix in?

First, mix the slime with other compostable garden waste (and possibly some kitchen organic waste). Then add the worms along with some soil. That will make it work.
