What do I
mean by that statement? I mean that
historically we are removing excess sand for up to two weeks after
aerification, however, this time with more expense we aggressively rotated the
mowers to hasten the process, performed extremely heavy fertilizations, and the
even more so we have had fantastic weather we are having to expedite the
recovery process with higher than normal heat and humidity. Other than some spot plugging on holes 1, 4,
5, 8, 11 & 15 most of the greens are about a week ahead of plan thanks to
these processes and weather.
12's Green - Slightly Scalping Due to Thatch |
All of
today's processes, along with the starting of the growth regulator application are
for one goal ... increase green speed.
So what else
to expect? Since we have stopped
chemical transition in 2010 in an effort to save funds for the Club, the roughs
and the fairways are still poised for transition. Presently there is an average of 50% ryegrass
remaining in the fairways. Here at
Avondale we purchased a hardier ryegrass since we do not have wall-to-wall cart
paths, which will handle the excess cart traffic during season. This also slows its removal in the summer
thus reducing the spread of the common bermudagrass that we have here. Over the next couple of months this
transition will continue in the approaches, fairways, select (non-328
bermudagrass) tees and roughs. We will
address these areas as they occur.
14's Fairway Going Through Transition |
So the last
question you may ask is “why did we sod the same areas on the greens again this
year?” This is a great question but not
a simple answer but here is the quick and dirty version. New bermudagrass sod requires 100+ days of
growth to improve its chances of survival, and ideally is not overseeded for
one year after. The one year not
overseeded is not realistic for us here at Avondale but the 100 days is
possible. Last year I debated with JC
Resorts to sod early like we did this year, but they decided not to go that
route … I did, however, in July of last year go ahead and sodded these extremely
bad areas to improve the conditions for our summer members. I used funds and savings in other areas of my
budget to pay for this sod work thus I still kept my budget within line. Sadly, 70% of these areas did not survive the
overseeding process since they were not fully established. This summer, we increased the survivability
by given the sod 100+ days of growth.
I will note
that there will always be some problematic areas on the greens during
transition such as on 1, back of 5 & 10, 11 and 12. You may ask why? And what can we do to fix
this problem permanently. On the 1’s
green – remove the large eucalyptus next to the green who’s roots are damaged
that side; same holds true for 5 (the
palms and shade issues on side and back, 10’s back where the large eucalyptus
encroaches the green. On 11’s green
there are two major issues one of which holds true on 12 & 15 as well
… extremely poor percolation issues
thanks to years of tilling in the bentgrass root mass long before the
conversion. Additionally, 11’s green
faces major shading issues on the back and left side, and some root
encroachment.
To address
these issues we also trim the trees surrounding the greens every year just
before overseeding; and lastly aggressive aerifications and deep drilling to
address the percolation issues. Other
discussions to how to best address these issues have been in the Green
Committee for potential rectification.
