Timarron Golf Course Update March 2020



       
         
            This winter has certainly been challenging with the amount of rain and cloud cover.  Bunkers have washed out several times, clogged drains have become normal, weed pressure is high, and greens have been slower than you’re accustomed.  That being said, the golf course is in a good spot to have a wonderful 2020.
            Ive been at Timarron for 6 months and have brought some new ideas.  The ideas I present have worked well at my previous properties and will continue to work in the future.  Prior to making any major decisions, discussions are had amongst the Timarron Golf Committee members.  Last August a golf course maintenance blog was created to help with the communication process and we have had 4000 page views since inception.

Greens

            The first 6 weeks of 2020 the course received 100% more rain than average.  With heavy rains comes high disease pressure that can kill grass.  December through February is the worst possible time to lose any grass on our putting surfaces because recovery will not begin until the temperatures begin to warm up.  A conservative mindset was taken during this period and the speed of the greens reflected that.  Not adapting our putting green maintenance practices to the weather significantly increases the chances of patchy, dead turf, that needs to be replaced with sod.
            Our putting surfaces are where they need to be this time of year.  They are healthy, growing, and look great.  Over the last 2 weeks we have increased our aggressiveness of putting green management.  We have been double mowing, rolling, and lowing the mowing heights.  We will begin to verticut, sand topdress, and apply growth regulators soon.  March to October is the best time to be aggressive with the putting surfaces because the grass is growing vigorously and can recover from stress.
            The goal for Timarron is to have a daily Stimpmeter reading of 10.5 to 11 feet, 365 days a year.  At this speed we can achieve consistent ball roll and turf health on a long-term basis.  Over the last week we have begun to fall into that range.  As a reference, a PGA tour event will stimp at a minimum of 12 feet.  Bermuda grass loves the sun so when we get into a weather pattern of extended cloud cover and rain we must adjust accordingly.

Driving Range Tee

            We've been keeping the members on the left half of the DR tee for the last 3 months on Friday, Saturday, Sunday when the grass is being used.  In March, we will switch to the right half of the DR tee.  At that time, the plan is to aerify and aggressively fertilize the left half of the tee box to encourage bermuda grass growth and recovery. 
Once the turfgrass on left half of the tee is fully recovered, we will switch back and do the same process to the right half of the tee.  This will allow members to have good driving range turf on a consistent basis.  In order for this to be successful, members are encouraged to utilize the small driving range at the far end of the range especially for practice versus pre-round warm up.  It has received very little use this winter and the turf quality is terrific.

Chipping Green

The decision was made not to overseed the chipper approach this winter.  The reason for this was to help control the winter weed poa annua.  Poa is a huge problem weed that will take over putting greens.  Poa is a prolific seed producer and adapter.  Many herbicides that have worked in the past are now ineffective.
Poa cannot be removed from overseed.  Any herbicides that are applied in an attempt to kill the poa will also kill the overseed.  So, the overseed acts as a safe haven for the poa.  The poa seeds then get tracked onto the green.
            We have hand picked thousands of poa plants out of our greens this winter.  The chipping green has been by far the worst.  By not overseeding the chipper approach in the future, we have some pre and post emergent herbicide options that will help contain the spread of poa.
