Greens Staff Update
With the recent foggy weather, I thought I’d dust off another posting from the past.
The course has been socked in with fog over the last 2 weeks, which has positive and negative benefits. The cool temperatures have allowed us to greatly scale back on the irrigation of the course and not use as much water. The grass definitely loves the cool weather too. That’s pretty much where the positives end and the negatives kick in. There are some excessively wet areas popping up all over the place, especially in the rough and under trees. One instance is when the fog is low enough and gets hung up in the trees it actually rains in many of these areas and becomes excessively wet. The other problem is the excessive wind; it never stops blowing up here and this time of year is just off the charts. I’m constantly looking at the wind forecast and researching the previous night’s wind record to find out the best and least windy time to run the irrigation cycles. The photo below will help me explain what happens. The prevailing wind comes from the bottom of the photo and goes to the top (West to East). The red star indicates the location of the sprinkler head. When the sprinkler is spraying into the wind it doesn’t throw at its maximum capacity and is thrown back causing the area to receive excessive water (yellow arrow). When the sprinkler is throwing with the wind the water actually overshoots the target and causes the area to dry out (blue arrow). This becomes even more pronounced on hills and open areas.
We do our best to adjust sprinklers and many times turn them off when this seasonal occurrence is in full swing. Please be mindful that we are trying to isolate these excessively wet areas and not overwater areas as best we can.
Quad-tine aerating the practice green…all set for Monday.
Greens Staff Update
Take 2…On Monday, August 25th, we will be quad-tine aerating the greens. This process will involve pulling a 1/4” plug out of the greens. Once that is complete we will apply a small amount of sand on the greens and water them in just as we have in previous trials. This practice has many benefits, including proper air and water movement that will stimulate root growth. It will help eliminate the sealing off that occurs during the summer months, allowing water to move more freely to the roots. It also helps control thatch that could become a breeding ground for insects and disease. I’ve posted a video on my blog, mvgreens.blogspot.com, from the USGA that helps explain the process. We tackled the clubhouse practice green this morning to dial in our machines for Monday morning. This will give you a good idea of how the process will look. Have a great weekend.
