Will rotting apples lower the pH of soil?

Asked July 8, 2019, 11:20 AM EDT

I will be putting in a row of blueberries soon at my place. I was told that rotting apples will lower the pH of soil for blueberries. I'm skeptical - I could not find any information that suggested using apples to lower soil pH. My guess, is the best solution is to use elemental sulfur. I appreciate your advice.

I'm on the same page with you.

While composting plant materials do produce organic acids during their decomposition, ultimately they will rise to neutral.

For a lasting change of soil pH, use sulfur. Is your idea to change soil pH based on a soil test? How long since there has been a soil test?

Yes, I have a soil test kit meter and have used it before planting my other blueberry plants.
I used elemental sulfur to bring the soil to the correct pH level for blueberries.

I plan on planting about 50 ft of berries. Can you recommend two different varieties with the same blossom time and is suitable for zone 6? I'm in Eastern Oregon.

Ach, I am the LAST person to ask about a variety recommendation. the berry specialist is out on vacation for most of the rest of the month. Have you seen this publication by OSU Extension?
