Substitute shredded pine for pine bark?
I've tried really hard, but I cannot locate bark fines. The bark mulch I can find is way too big.
As an experiment, I put a bag of pine mulch through a screen. I threw the large stuff on my paths, and mixed the fine stuff with peat and pearlite. It seems like a nice, fluffy, structural mix.
Could this work? From what I can read, the downside could be the use of N by the breaking down of the pine. Could I just make sure there was enough additional N for the plant?
Is there another problem I don't see?
Thank you for your help.
