It was just a quick razz.
Actually in reality PH does fluctuate in a major way in my area...i learned PH in the old days...plant in areas which you know the trees and plant naturally live in soil with proper PH. Try to plant in a cedar or pine forest and you know what you get!! On the other hand a maple, oak or birch forest has tremendous dirt proper PH and does a fantastic job on grass. I learned outdoor growing the old school way...trial and error. No fancy meters or fertilizer...just instinct and learned skills.
