Yeah, I'm a master gardener through the Clemson extension program. They really push those soil tests hard! Lol! But I've never taken one from my yard! I'm pretty sure they are free up in NC! I need to make it up to the JC Raulston arboretum one day, hear it's great! I'm more of a plant and tree guy as opposed to turf! Y'all have some great nurseries up around the Raleigh area! Made it to Cam Forest open house in October, would like to get to Plant Delights nursery one day!
