Will wood bark as a mulch cause nitrate deficiency?
Hello, this autumn I planning on planting a few trees(hazel-holly) and bushes(elder - all of them will be bare root), I want to apply a nice hearty mulch to these to protect them, I was planning on using cocoa shell nibs but they're way out of my budget! The next thing I can use is wood bark, obviously cheaper, one worry I hold is that I've been repeatedly told that as this mulch breaks down it removes nitrate from the soil. Will this cause nitrate deficiency? I only plan on mulching until they're established Thanks
