 Now, I've always talked about soil tests. This is where that comes in key. It tells us exactly where our pH level is so we can say these are the plants that are going to grow here, these are the plants that are going to grow here. So if you've done all that, you're probably already ahead of me. But if you didn't do it, now you're wishing you did because we need to know what the pH level is to determine how much we are going to use to bring that pH level up.
