I have never bothered to test mine, I just plant it where I want and watch it grow. I am surrounded by hemlock,fir,pine,alder trees and they tend to make soil acidic so does scotch broom tons of that crap around here too. If you do the lasagna beds they stay balanced all the time and you don't have to add extra stuff to them. they just do things perfect from the get go.
I was able to start a raspberry seed right now it's about 2 inches it doesn't seem to be growing very fast I'm going to move it to a larger pot hopefully that will do it
From what I've been reading pH levels testing is very important
I tested my pH soil level today it was 6.5 this tester is inexpensive and gets good reviews.
