    I don't know the answer either. One thing that seems to hold the general consesus is that: Ph changes s-l-o-w-l-y........

    I see your point about waiting till next year's blossoms - then going from there. :) I thought about that my self.

    The pinks are very easy for us here... especially with the crustacean marl left in many lake beds mixed in.
    The regular clay soil with composted leaves and such are easily purple, but have been unable to get blue yet. I am still afraid to use wood ash for potash (K).

    What is a good K fertilizer?
