Picture worth a thousand words

Here you can see the difference between the center of the green with less traffic and moisture stress and a plug taken from an edge with high traffic. The short one was taken at the walk-on on #14. The long one was taken from the center of the green.

It doesn't take a turf expert to tell which one is healthier.

This is the major battle with new greens. Keeping the edges healthy and alive. As the green ages the difference between these areas will become less and less severe.
