Acidity of spaghnum peat moss
I would like to use some hardwood ash (I’m aware that ph of peat moss is 4-4.5) in my spaghnum peat moss/vermiculite for starting seedlings this coming spring (in containers) but I cannot find a formula anywhere on how much to use. I was just going to use a tablespoon or so but I decided I better check first. I am only using a 2.2 cubic ft. bag of peat for the project. Any suggestions on a proper amount to use? Thank you.
