We have begun our typical summer rain pattern. Glorious mornings, heats up fast, cloudy afternoons, and rains in the late afternoon....YEAHHHHHHHHH! As you may recall from the last posting, even though it was summer water was in short supply. Now, Mother Nature is lending a helping hand.
We are still rolling along with the summer plans. Next week we are closing again for aerification. I am anticipating this time to go even more smoothly than the last time since we now know what to expect with the new course. The only thing different this time is that we will verti-cut the fairways and then topdress them. I eliminated this process in June since we were still unsure about available irrigation water. Now that its raining, there should be plenty of available water from the City so we can move forward with all of our plans.
A few things have happened recently that I thought I would share / educate everyone on. One being a recent application of a product called Curfew. Curfew is a soil injected pesticide that kills microscopic root parasites called nematodes. These parasites severely inhibit the grass roots from being able to supply the leaves with enough water and nutrients, thus causing drastic thinning of the canopy as seen below in a picture of #6 tees.
The material used to control nematode populations is sliced into the ground 6 inches deep and injected as a liquid. The liquid then volatilizes and diffuses up through the soil profile to reach the targeted pests. Here is a pic of #1 after treatment. The brown lines are not burns from the applied product, they are from where the injector cut the grass that was laying over and the leaf tissue died. Similar to if you cut a branch from a tree, the leaves will die because they can't receive any water or nutrients from the roots.
This is a pic of #14 fairway where the nematode population devastated the turf. These areas will be put on a heavy fertilizer diet to promote rapid recovery now that the root system can supply the leaves with what they need. Notice the lines running through the bare area. Again, that's from the process of injection.
A couple of days ago I was asked about our green's verti-cutting process. The person had seen it happening while playing, but didn't understand what all the machines were doing. Take a look at this short video I shot to help explain what we do to manage the thatch on the greens. Notice all the people and machines, this process takes 10 people to do it.
