When I looked at the hourly weather forecast on Saturday morning, I had my doubts that we would be able to aerate greens on Monday 3/25/19 as planned. However when checking again on Sunday I was pleasantly surprised to find the impending storm had pushed to later into the afternoon, and we were just able to get greens 1-18 & Upper PG completed before it started raining.

Below is a quick pictorial of the process we just completed. We've provided this step by step pictorial before but for those who might just be starting to follow these updates and are interested, here you go.
| Second step is to remove the cores. We remove the cores with a machine |
called a core harvester. This is the machine that allows us to complete
19 to 21 greens in a day.
|Core Harvester first lifting, then ejecting cores and soil into the back of a utility vehicle|
|Third step is to apply sand topdressing. We purchases a very high grade |
USGA spec, kiln dried sand to fill the aeration holes and firm the surface.
|Fourth step for us is another type of aeration called deep tine aeration.|
The above mentioned core aeration penetrates to a depth of about 4"
whereas deep tine aeration penetrates up to 8". Even though this process
does not extract a core it facilitates deep drainage and air deeper in the
root zone hopefully encouraging deeper rooting.

rain started. Much better overall filling of the aeration holes.
There is still allot of what we call "tweaking" that we do to the greens after this initial aeration to get the holes covered and the surfaces firm, and back to pre-aeration putting quality. These "tweaking" practices include additional lighter topdressing's, fertility applications, seeding, rolling and vertical mowing which helps get the sand into the turf canopy and grass to cover the holes. Weather permitting we can usually get the holes covered in a week to two and back to pre-aeration putting quality in four weeks.
