Dealing with Summer Stress

Turf decline during the summer months usually is a combination of many factors. Here at PDS our turf issues usually revolve around mechanical stress(frequent mowing and cart traffic) during prolonged periods of high temperatures(not enjoyed by cool season turf), and disease from high humidity after heavy rainfall during the monsoon season. Some of the practices we do before and during this time to try and stay ahead of the game are:    hand watering and syringing, needle tine venting of greens, solid tine aeration of hard compacted areas in fairways, spoon feeding nutrients, applying preventative fungicides, spraying wetting agents/penetrants to needed areas and alternating between rolling and mowing greens during high stress periods.

Needle tine venting..... it's all about the root zone

This process creates a small hole in the green surface without removing any material. A relatively painless process that helps relieve compaction and more importantly increasing oxygen content in the soil for better root and soil health and displacing harmful excess build up of CO2(carbon dioxide). 
We alternate every 2-3 weeks during the summer stress periods with either a 5 or 8 mm tine at a depth of 3" on a 2" x 2" grid.

Summer stress and the Poa(annual blugrass)

The poa in our fairways usually starts to check out once we start getting extended periods of tempertatures around 90F and soil temperatures in the 70 -77F range.... and then you factor in the high humidity during the monsoon and our cool season turf is NOT very happy. Cool-season turfgrasses optimum growth level is at temperatures between 60 and 75°F . So when we get these extended periods of heat the already weakened plants will be extremely susceptible to damage from pressures such as heat, drought, traffic, disease, and insects. I'm sure many of you have noticed these areas in our fairways. In these areas we will continue doing a few different things. We will continue syringing these areas in the mornings and afternoons to help keep the canopy cool. We will also aerify with solid tines to increase oxygen levels in the soil and help with water penetration. We have also started to slit-seed the really bad areas in the fairways to try and establish some new growth during the monsoon.

In Remembrance.......Oscar Perez

I was deeply saddened to hear of Oscar's passing on June 20th and would like to take a moment and extend my deepest condolences on behalf of the entire staff of GMS to the family of Oscar Perez. My sincere sympathy to his wife Martha and son Oscar Jr.

Oscar started out as a groundsman for my father back in 1990 when Castle & Cooke still ran golf operations and was eventually promoted to lead mechanic. He held that position with C&C, Valley Crest golf maintenance and GMS. Oscar retired in 2017.

Oscar's contributions during his 27 years here at Pueblo del Sol are far to numerous to name. Working with Oscar for 20 of those years I can tell you his strong work ethic, integrity and willingness to help others in need always stood out for me and personally will never be forgotten.

Thank you Oscar, not just for the things you did here but for being my friend. 

When I'm Gone

When I come to the end of my journey
And I travel my last weary mile
Just forget if you can, that I ever frowned
And remember only the smile
Forget unkind words I have spoken
Remember some good I have done
Forget that I ever had heartache
And remember I've had loads of fun
Forget that I've stumbled and blundered
And sometimes fell by the way
Remember I have fought some hard battles
And won, ere the close of the day
Then forget to grieve for my going
I would not have you sad for a day
But in summer just gather some flowers
And remember the place where I lay
And come in the shade of evening
When the sun paints the sky in the west
Stand for a few moments beside me
And remember only my best Mrs. Lyman Hancock
