Greens Update.

The greens continue to heal from last weeks aerification. I have had a few comments and questions about their speed and want to assure everyone that everything is going as planned. Following aerification we allow the greens to rest for a full week, giving time for the plant to grow into the sand topdressing. We began mowing on Monday 5/26, but at a higher height of cut, without baskets, as to not pickup any remaining sand. On Wednesday we began cutting with baskets and on Friday we sharpened and lowered the greens units to our regular mowing height. It will take a few more days for the greens to return to their normal speed. All things considered, everything went as smooth as one could hope.

Greens Aerification

Due to last weeks heat, greens aerification was postponed, taking place this Monday. We slightly adjusted our process to be a little less invasive, making sure the greens would be healed on schedule. Instead of larger holes on a tighter spacing with a heavy topdressing, we decided to go with a double verticut, followed by smaller holes at a medium spacing. A fair amount of topdressing sand was applied to complete the process. The guys put in a long, hard day on Monday and the greens are looking great at this time. Although it is not what we had originally planned, I think our amended process just might be exactly what the greens need at this time. I appreciate everyone understanding our need to move this process back a week.

Greens Aerification Update

It looks like, for the first time in my career, that we are going to postpone our greens aerification until the following week. The weather forecast is calling for several days of excessive heat and the risk of lasting damage to the greens is too great. Our original plan was to go with 1/2" tines, tightly spaced, and a lot of sand. However, to have the greens healed on schedule, we will adjust our process by using smaller tines and less sand. Although this is not ideally what I would like to do, in the long run it will make little difference to the quality of the putting surfaces.

Heat Stress

The stress from the recent heat and wind are beginning to take their toll on the golf course. Although we have been working very hard to improve our irrigation uniformity, inefficiencies are easy to spot when the system is put to the test. While I do believe that we have improved how well we are able to water, we still operate at about only 80%. The greens are doing well, with only minor stress showing in a few locations.


Drought stress #14 green

Fairway aerification and seeding was wrapped up today, and we continue to water nightly to help germination and keep the new seedlings from going into drought stress. The poa obviously struggles the most in high temperatures. With a root system of only about 1/2 inch, poa quickly dies without repeated light watering.

Hopefully, such extreme weather is only an isolated event and not an indicator of a tough summer ahead.
