Hi to all,
I am making a super soil mix for future use. I have some potash which is a little course, not like a powder. Is this something that I could put into the super soil mix? If so, do i need to grind it up into a powder before doing so? Or is Potash more for treating deficiencies as they arise?
I see information about potash but can not seem to find anything on it in super soil. It seems to be something that would slow release so thought it could be used.
