Every couple of weeks during the summer, once a month over the winter. Used to do it weekly, but decided I should probably let it heat up more between turns.

I do it by getting a fork and properly turning and mixing it. Very physically demanding!

I only really have the one 800 litre bin though. I think the let it sit strategy works better when you have 2 or more, just layer well and let nature do the mixing!

I’m usually really bad about turning it, perhaps once a season. I’ve been doing it more monthly lately though, my piles are definitely running warmer now.

I spin the handle on my drum composter every time I add to it. The other bins seem to be turned every 6 months.

I rarely ever turn my pile often enough…

I wish I had a bobcat or other bucket loader, or the motivation to build enough hand crank tumblers to handle the volume I have

I live in Phoenix and just started to water and turn my compost daily during the summer. It looks a heck of a lot better. However, I always regard my “summer” compost to be nothing more than topsoil by the end of the season. At least it’s good for something.
