As you know spring aerification is a necessary evil. In the spring at DMGCC we use solid tine to just poke a hole in the turf. This hole gives the ground a chance to breathe and it gives it a great opportunity for good gas exchange. The tines that we use on greens and tees are just .25" in diameter so they heal over very quickly are and they are very minimal in the disruption to the golfer.
On the fairways we use a bigger diameter tine .75" and we go a little deeper. But these also heal over very quickly and are very little concern to the golfer. We have the South greens done, tees and fairways will be completed this week and the North golf course will be done next week.
