Last fall before we closed the golf course down for winter, we deep-tined our putting surfaces.  We went with 7/8" tines that went down about 10-11".  The main reason we did this was to avoid water ponding on our greens over winter.  The picture below will indicate we have another side benefit from last fall's deep-tine procedure, deep elongated roots.  The last couple of weeks we have noticed roots like the one in the picture coming out of the deep-tine holes.  This will have long lasting benefits as it is a great indicator of plant health. 

Next week we will again be deep-tining our putting surfaces.  No need to worry about playability since the tines will be much smaller and will have almost no impact on play.  But it will have a HUGE impact on increased root depth.  Look at it this way ... roots live in air not in soil.  Our soils here at Ridgeway are a heavy clay mixture, which makes it hard for roots to find away to go deeper because the pores (air spaces) are so condensed.  Our putting greens have about 3" of sand topdressing on top of a heavy clay subsurface layer. By poking holes down 8-12" we allow easier access for roots to grow deeper.  With that we also have many side benefits of less compaction, better water infiltration, and better gas exchange. Deep-tining is something we will do on a regular basis and I think you will like the results.

This is a picture of our cup-cutter.
Notice the long white roots hanging out the bottom!
The roots in the deep-tine holes are about 9-10" deep.
All the more reason this has to become a staple in our management program
