If
I were a corn grower right now, I'd be loving this hot weather! But I'm
not, I live turfgrass, and it's sort of ironic that they classify the
grass in this region of America, cool season turfgrass. Corn is a
monocot also, but it loves really hot days. Turfgrass not so much.
Yes,
that's me in my in-laws cornfield a couple of weeks ago. They are Bill
and Sharon Wintz of Milford, Iowa, and as you can see, they have a
beautiful piece of America's heartland. They tell me you can almost see
the corn growing on a real hot day. The classification of cool season
turfgrass for our area is correct though, as we're growing grasses that
grow best in cooler temperatures.
This extra hot weather we're
experiencing now, increases the need for irrigation of our turfgrass. We
would prefer not to water as much as we've been forced to, as playing
conditions and the health of the grass are both compromised. Soft greens
occur when we have to cool the turf during the day, and roots actually
become shallower and weaker with the constant availability of water at
the surface. Each time we've attempted to withhold water for the sake
of playing conditions recently, it's come back to bite us, with wilt
occurring in the hot afternoons.
We're between a rock and a hard place,
as the surface needs to be cooled, but the soils beneath are already
saturated. Unfortunately no one wins under these conditions. We are also
nursing along certain areas on greens right now that are suffering from
a number of damaging conditions, including poor surface drainage, poor
water percolation, weak roots, shade, and increased traffic levels.
Turfgrass thrives in temperatures between 55 and 75 degrees, and we're
well beyond that right now. Our turfgrass will hold up though in the
majority of areas on the course and the course will continue to play
nicely.
We are evaluating some of the weakest areas on greens this
summer, and determining what steps or procedures we can take to
alleviate any poor conditions that exist that is contributing to the
decline of turfgrass. Glass half full, as we will improve these areas
once more favorable weather arrives and we determine the correct
cultural methods to alleviate some the detrimental things occurring in
those areas.
