I got a free bag of “soil media” from a friend consisting of 89% thermally processed wood fibers - it looks like shredded peat or coco coir…very fine and highly processed (not like wood chips at all).
Could I use this for container gardening like a coir mixed with other things like perlite for drainage? Anything to worry about in terms of pH or aeration?
I personally wouldn’t want to use wood in my soil. At least for the plants and trees I grow. It’s hard to avoid using bagged soils. And there may be exceptions for some trees that may require stuff like Orchid bark. Roots don’t want dead rotting medium around them and it’s not common in nature. That all occurs on top of the soil then breaks down and feeds below. Instead of breaking down and turning into an anaerobic disease or death trap like per say an avocado tree would die.
My impression is wood products in soil is one of the biggest scams in the plant world.
And it seems many into believe it’s great while companies get rich selling an inferior product. That’s just my take. I’m sure plenty of nurseries and people that sell trees or plants in containers would disagree since big ag told them so for over 40 years now.
@Lucas what type of medium do you use in your container garden? is there anything special you have to do like refresh the medium every x years or just adding when it sinks and during uppotting? are there plants that you grow that you have to have a special medium for? what is the longest amount of time you have a plant in your medium? their container thread for reference: My container fruit jungle
I would use that as mulch 
100% agree with all of this.
I use Top Pot that I mix myself: peat moss, pumice, perlite, sand, charcoal for all plants. I don’t use coco coir either. There is no sinkage, if anything, the soil rises as the roots grow. I never refresh the soil either, its all rocks and sand lol.
My avocados are in 25g grow bags on their 4th year in the same containers. They will need to be uppotted or rootpruned at this point.
