I have a dumpy bag of conifer chippings which have been sat there for seven months. It looks the same as it did seven months ago. I am intending to use it as a mulch on a woodland, mainly rhodedendron border. Will the tannins have gone now and will it be ok to use? would it be a good idea to mix it with grass clippings to speed up the composting and reduce the anticipated uptake of nitrogen when put on the soil?
You don't really need to worry about it taking nitrogen when used as a surface mulch, Judith. If you wanted to mix it with the soil to improve the soil structure, that's when you could come across this problem.
Thank you. Have had conflicting advice.
