What a summer we are having. Despite all of the negatives Mother Nature has thrown at us the golf course is holding up. We do have some battle scars. We hope to keep anymore damage to a minimum. My staff and I are trying to keep the course in the best shape possible. My earlier post I told you how we were taking care of our greens. We will continue alternating mowing and rolling through the month of August. We will be over seeding all of our greens in the middle of August. We are trying to incorporate as much of the newer bentgrass varieties into our older greens. This is the third year we have done this. The newer bentgrass is a much better variety than the older bentgrass the greens were seeded with 30 years ago. The newer bentgrass is more heat tolerant, disease resistant, and finer leafed which gives you a better ball roll. Over time our greens will have more newer bentgrass than old. This has been a very hard year for all golf courses in the Midwest. Dr. Lee Miller our Extension Turfgrass Pathologist from the University of Missouri sent out the letter below to all golf courses in the Mississippi Valley. This explains the difficulty our turfgrass is going through. He explains it very well. Again, thanks for reading my blog. I hope you find it useful and informative.
This Season
Unprecedentedly Sucks
In many cases, a
diagnostic analysis and microscopic scan can’t absolve the weather cards this
region has been dealt… seven-two off suit and in for the big blind. Likewise,
magical elixirs from sprayer boom nozzles don’t alter the growing environment
or provide instant recovery. The fact of the matter is that European born
bentgrass prefers 55 – 75 F, which was nowhere to be found in spring 2018. The
second coldest April, followed by the warmest May on record is one of the
biggest anomalies on record in Missouri, with the last one in back to back
months occurring in a cold December 1989 and warm January 1990. Those growing
grass then, did you care? Probably not, since you probably didn’t even need to
mow it. June did what June does, providing another blow and ringing in as 6th warmest
on record.
Spring, not winter, is
the time to put money in the bank with bentgrass root growth and structure to
get through the summer marathon. Also, recall last fall. The lack of rainfall
had many recharging irrigation systems to get through Thanksgiving and supply
bentgrass roots with enough water to get past old, dry, and cold man winter.
Bentgrass putting green root systems, the fibrous source of quality golf in
Missouri, have not had consistently good growing conditions since spring 2017.
If misery loves
company, know that 59 samples have been submitted to MU since June 1. For
perspective, 4-6 samples on average are processed per week, meaning twice that
have been submitted in the last six weeks. Other than physiological decline,
lance nematodes, Pythium root rot, and black layer are most often observed this
year as being the primary or contributing factor to bentgrass decline. Prevent
root diseases, manage water in the root zone precisely, and don’t get rough
with the surface (no verticutting, smooth rollers, roll instead of mowing if
possible, etc.).
“Survive and Advance”
is an ESPN “30 for 30” production about the magical run of Jim Valvano’s NC
State Wolfpack team. I graduated from NC State so hold that team and its
underdog nature in the highest of regards. While Coach Valvano is perhaps
best known for his bravery and selflessness in the face of cancer, he also led
that 1983 team of young men through nine elimination games in a row, seven of
which they were losing in the last minute (hence the moniker “Cardiac Pack”).
Not to be overly dramatic, but the individual bentgrass plants on your putting
greens are that team this year. Weather in this upper transition zone is
always challenging, but this year it’s like playing against Phi Slama Jama.
Let me know if I can
help. Hang in there. Support each other.
