DRYJECT GREENS AERIFICATION NEXT WEEK

On Tuesday, September 10th the golf course will be closed for a Dryject greens aerification.  This contracted aerification uses a very specialized machine to inject sand into the greens using high pressure water. This is a great tool to get a lot of sand into the profile with minimal surface disruption. 

GREENS AERIFICATION NEXT WEEK

The golf course will be closed Tuesday, September 3rd and Wednesday, September 4th for greens aerification.

TEE AND FAIRWAY AERIFICATION NEXT WEEK

The golf course will be closed Monday, August 26 and Tuesday, August 27 for fairway and tee aerification. 

COURSE CONDITIONS 7/18/19

CART PATH ONLY FRIDAY JULY 19TH - SUNDAY JULY 21ST Due to the extreme heat expected Friday the 19th through Sunday the 21st, and in an effort to protect your golf course, the cart rule will be CART PATH ONLY. We apologize for the inconvenience but allowing carts to drive on the turfgrass could be detrimental. On days of extreme heat, cool weather loving turfgrass may become so stressed that simply driving over them may cause injury or even death.  Please understand that we are trying to save the course for the rest of the year.  Tire tracks like this can take a very long time to heal:

The grounds crew is very busy trying to keep as much turf alive as possible through this period of high temperatures.  You may also see hand watering or irrigation heads running to cool the turf.  The purpose of this "syringing" is to cool the plants through evaporation -- not to wet the soil.  This practice works only in certain circumstances and must be employed carefully.  During these hot periods, too much water is just as bad as too little.  Please be patient if irrigation heads are running or we are hand watering greens during your round of golf.  We will do our best to stay out of your way, but it is not always possible during this time of year. Thank you as always for your continued support of the Golf Course Maintenance team here at Chantilly National!

KILLING KYLLINGA (YEAR 4)

We are now entering year 4 of our targeted attack on the Green Kyllinga in the Ryegrass collars. Our efforts the first couple of years were very effective but not completely successful. The seemingly endless rain of summer 2018 really shifted the conditions to favor the Kyllinga.  A few of the areas, although much smaller than before, have returned.  So, herbicide has once again been applied to the collars and spot treated in several areas throughout the course. The first app went out 4 weeks ago and the second this week. As before, when the weeds die back, seed and sand will be applied to the voids to grow the affected areas back in.

For those that may have missed it, below is a copy of my post from last summer about this challenging weed.

Green Kyllinga

Green Kyllinga is a relatively new problem at Chantilly. Until a few years ago we were fortunate to not have any on the property (or at least not enough to gain my attention). The Kyllinga is aggressively encroaching on several of the greens and fairways but is the most severe on the collars. Chemical controls have been in use since late spring, you may have noticed the bare and thin areas on many of the collars, these are the areas were the Kyllinga was treated.  

The plan has been to treat the Kyllinga with an herbicide and seed the bare ground. So far is has been relatively successful but Kyllinga is a very pernicious weed and does often return after treatment necessitating subsequent herbicide applications.

We will continue throughout the summer and fall months to treat and retreat this invasive species and continue seeding until the Kyllinga is a memory.

The image below shows the untreated Kyllinga.  

This image shows a collar after the Kyllinga has been treated and the voids filled with a sand/seed mixture.

The final image show the weed re-emerging after treatment through the sand and seed mix.  This is the reason repeat herbicide applications are required.
