FALL AERATION COMING SOON!

Labor Day is nearly upon us so we thought we would provide a friendly reminder that fall aeration will take place on September 7 & 8.  We will have 9 holes closed each day to allow the greens to be aerified.  We have already begun the green healing process: we have applied fertilizer and have withheld application of plant growth regulators.  This (along with cooler weather) will provide a flush of growth which will aid in speedy recovery of aeration holes.  We will also be diligently assessing ball roll and will topdress the greens until they are rolling smooth and true.

The fairways and tees will be aerified once the greens are finished and should be completed by September 16- depending on weather.  These areas will not require closures and should cause minimal disruption to play.

USGA VISIT

Our Midwest Region USGA Agronomist, Ty McClellan, visited Wakonda on Wednesday, August 17.  Ty spent the day with John Temme and the green committee discussing the golf course.  Ty was complementary of the condition of the golf course given the extreme heat experienced in July.  He said that our collars looked better than average and said we are taking the correct measures to promote overall collar health and recovery.  Ty also added that our greens once again had the best roots he has visited this season.  

Roots on #11 green extend well beyond Ty's soil sampler.

 The entire grounds crew is currently enjoying the cooler weather.  With the drop in temperatures we have begun our efforts to seed various areas of the course which died this summer.  Areas seeded include: low- lying fairways, 10 tee, and small patches in the collars and first cut of rough.

Areas like this one on #8 have been seeded and should recover through the fall.

 We have also started a few other projects this week:

Drainage being installed in front of the indoor practice facility.

We are also cleaning up bentgrass invasion along pond banks.

You may have also noticed that climbers from Perficut removed a large dead oak near the 13th fairway.

August Update- Hot and Dry is Better Than Hot and Wet!

It has been a hot, dry second half of summer 2011.  Earlier this year we were quite wet- in May and June we received over 15 inches of rain.  July was a month that was touted as the "Hottest July since 1955" by KCCI.  While some areas in the state received rain, Wakonda did not. We observed only 1 inch the entire month.  The hot and dry conditions had us battling to keep the irrigation system running smoothly so we could give our turf the moisture it desperately needed.

When conditions are hot and humid, turf disease pressure skyrockets.  It is a daily struggle to 'walk the fine line' between giving the turf enough water to handle the heat while avoiding over watering which exacerbates disease issues.  To avoid this scenario each green is scouted every day, checking overall soil moisture and for localized dry spots.  Each green receives an individual watering plan- countless hours of checking and hand watering and the result is healthy turf.

While the past several weeks have been a challenge, we are much happier with the condition of the course than we were this time last year.  Summer 2010 was a very wet and hot season.  Turf everywhere struggled to survive the many pressures- at least this July we were able to control how much water falls on the course.

Greens- are performing phenomenally!  Roots are strong and deep (8+ inches).  Ball marks are slow to recover but we are masking their appearance with green sand.  Speeds are holding steady.  You may have noticed a slight dip in speeds during the hottest days in July as we were forced to back off our maintenance a bit to avoid over stressing the turf.  With the cooler temperatures we are back to our normal routine.

Collars- have responded to aeration and traffic control efforts.  Their condition is slowly improving.  Cooler weather will be the key.  We will continue our efforts to the nurse them through summer.

Tees- are doing well.  We have seen some minor disease issues pop up but were able to handle them quickly with fungicides.

Fairways- are also performing well.  Our new bentgrass varieties handle the summer months much better than the fairways did in years past.  We do have a couple areas that are struggling.  The wet spring and early summer left the turf in low lying areas without strong roots- these areas are struggling with the hot weather.  You will also notice other small areas where we have some dead turf- this is to be expected.  We do have some Poa annua in the fairways and treated with Velocity Herbicide in May and June.  The heat has really added a knockout punch to a lot of Poa!

Number 8 fairway Aug. 6, 2011.  Some turf here is struggling.

The same area August 13, 2010- looking much worse.  Hot and dry is MUCH better than hot and wet!

Rough- is struggling in areas without good irrigation coverage and without the protection of turf fungicides.  The good news is this turf is better equipped to handle summer stresses and will bounce back on its own with the arrival of cool fall temperatures and a little rain.  Weeds are the most visible sign of stressed turf.  Crabgrass and nutsedge have carved out a niche the past few weeks- they love the hot weather.  We will selectively treat these weeds in areas of high priority to avoid using a lot of herbicide.  October frost will kill theses summer annual weeds for free!

We are using portable sprinklers to keep the rough green, as best we can.

Yellow Nutsedge.

Crabgrass.

Bunkers- We're glad to have been able to take a break from repairing storm damage.  We will give them more attention once the weather cools down a bit and we can divert our attention from the turf.  We will be inspecting them individually to redistribute sand and add sand where needed.
