Grow superior variety of blue berries

Asked May 17, 2020, 10:54 PM EDT

I have 2 questions: 1. What is the preferred soil pH for superior variety of blue berries? (Currently my soil is 7.5 pH,) 2. My soil has a lot of clay. I was going to dig out a bigger hole and replace much of it. Will adding Sphagnum Peat Moss make the soil more acidic or alkaline?

Thank you for writing.
Here is some information. https://extension.umn.edu/fruit/growing-blueberries-home-garden
This site answers your question about mosses. Note the very odd labeling which has a big effect on acidity. https://garden.org/ideas/view/drdawg/1972/Sphagnum-Moss-vs-Peat-Moss/ You want Spagnum Peat Moss or Peat moss. You do not want "Milled Sphagnum Moss," or "Long-fibered Sphagnum Moss."
