By now, you've probably seen this graphic relating to divot patterns on practice tees. The point is that from a surface area standpoint, an "in-line" divot pattern consumes far less square footage of turf compared to that of the scatter pattern or the concentrated divot pattern shown above. The more square footage of turf that is saved, means the tee itself will last farther into the season and remain in good condition. Studies also prove that divots heal faster this way compared to other hitting patterns. This is a simple practice that you can do to conserve the turf on the practice tee.
Place your golf ball immediately behind your last divot in order to continue the straight line divot pattern. These photos show how it's done. It's important to leave turf between the divot lines because vegetative growth is one way the turf grows to fill these voids. The other method is by the growth of seed, which is mixed into the divot filling medium.
