Update: I believe that the main reason we are seeing the seedheads on the greens this year is because usually we would of already made three growth regulator applications on the greens. This is a chemical when sprayed it slows the growth of the plant, it also has a good side effect of prohibiting seedhead production. We use the same chemicals on our fairways throughout the summer to cutdown on mowing frequency, clippings as well as the seedheads we are now seeing in abundance. I am still in the investigation stages about the patches and will pass more information along as I get it.
We will be making an application of the growth regulator to the greens tomorrow morning. while it will not make the current seedheads disappear it will keep any new ones from sprouting. In the future we will be sure to start this program before the seedheads start producing.
I was asked Saturday, what are those patches on greens #5 and #12?
As of this morning those patches are turfgrass with the grain growing in a different direction then the rest of the green. The real issue is that the turf is seedheading in these patches. I am currently doing some research on the patches in hopes of finding a way to take them out without killing the turf. There are only a few different reasons they may be growing. The most likely would be that they are mutations of the TifEagle turf. A secondary reason may be some of the old 328 tifway that used to be our greens may have survived the killing off of the greens when we replanted back in 1999. Our greens are 11 years old and would be just about the right age for mutations though. Since this turf was invented by the USGA by bombarding tifway with radiation I suppose anything is possible. I am trying to get the USGA to answer my questions about seedheading or mutation of this turf. Once I get an answer I will post it here for all to see. for now we will continue to verticut and topdress the greens as scheduled and the seedheads will eventually go away since they generally only seedhead during the spring.
