If you have a compost pile and it has started to get a little bit smelly, well, you're probably

0:18.9

not alone.

0:19.9

I think Tony, this is probably a thing that happens to almost everyone making compost for the

0:23.7

first time.

0:24.7

So Tony O'Neill is back on the show, founder of Simplified Gardening, and author of the

0:28.3

upcoming Web Composting Masterclass.

0:30.5

Tony, what would be the main reasons at least why someone's compost starts to smell?

0:36.7

Again, I think that the main controlling factor here is moisture, as I've spoken about

0:43.5

earlier on, the compost if it gets too wet, this pushes or fills up the air pockets with

1:31.8

And the best way to do this is we need to absorb that moisture.

1:36.8

To do this, we need to literally turn that pile out onto, you know, a tap or something

1:42.3
