|That's right, the temperature coming from our irrigation system is a tepid 84 degrees.|
I never dreamt our hand watering of wilted collars would precipitate further decline of putting surfaces and is the principle reason you no longer see us out "cooling" our greens. It can't be done when using this luke warm bath water! With soil temperatures at 78 degrees, we found we were compromising root systems by making the soil profile warmer! Not good for the plants, not good at all.
If you were with us in 1988 you might remember we did not struggle with our greens like we have this year when all watering was done by hand. Then 100% of our water came from a spring feed quarry, one semi tanker load at a time! That was a very bad year, this year by my estimation has been much worse.
Pray for a good soaker of cooling rain that lasts all day. No wind storms please. _Mk
