Just got a Pro-Plugger and have a 2 questions (Pic Below):
1. Does this look like a good core? Visually, I notice a top layer of sand from my top dressing efforts, but otherwise I don't know enough about what to look for.
2. I have a Soil Savy test kit - Not sure if this is the ideal soil testing option but I had thrown it in my Amazon cart last week. When providing them a sample, which part of the core should I be getting my sample from? Or do I mix all the soil up first? this is a 4" deep plug.
