Expert Response

Hi, Eric Roost:

Fir is fine, although it will break down over time.

As a comparison, I have black plastic composters, one 35 years in constant use and others of various ages - but all more than 20 years in use.

I also have raised bed sides in constant contact with soil; these have been completely replaced at least 3 times in 35 years, with plenty of little repairs here and there besides the complete replacements.

For me, having the light weight and reliability of the plastic is a priority. BUT there is no compost process nor quality reason that fir would not be equal to or superior to the plastic.

It's a matter of choice. However, DO NOT use wood that has been pressure treated or dipped in any kind of preservative.
