I was looking into testing the soil in my yard so I knew how much I needed to prepare it for blueberry plants. I came across a method I hadn't heard of before, that I thought was interesting.
It involved boiling cabbage leaves in distilled water, then placing the soil in the juice. Then supposedly the juice will change colors based on the soil's pH level.
It sounds pretty easy, but I was wondering if that's an accurate method for testing the pH of soil? Is it accurate enough for a general idea of where the pH is at, or should I not use that method at all?
