When aerifying greens we use 1/2-inch hollow tines on 2-inch centers. That gives us 49 holes per one square foot. Amazingly, this amounts to just under 5% of the surface being disrupted. That's it! It looks much worse then it actually is.

Once pushed to the sides of the greens they are picked-up:
Plan on checking out the blog tomorrow (Tuesday) with pictures of fairway aerification and an update on where we are at in the aerification process.
