Shade: Why it is bad even in winter...
Chris Tritabaugh, Northland Country Club, Duluth, MN:
"Yesterday I woke up to 37 degrees and a slight drizzle. Soon the drizzle turned to rain and after a couple of hours became snow. In the afternoon the wind turned from the NW and the temperature sunk like a stone. By the time I went to bed last night the temps were just above zero.
When it comes to turf, the weather we experienced yesterday has the potential to create disaster; especially when snow is present. This morning as I walked our daughter to pre-school I took note and a photo of the boulevard in front of our house. Our house is a two-story traditional and faces north. Due to this the front lawn of our house spends this time of year completely in the shade. With the constant presence of shade the small amount of snow we have had this winter has not completely melted here, as it has in non-shaded areas. If you click on the photo above you can see after yesterday's rain and immediate freeze, much the turf on the boulevard is covered in ice.
Now project this situation to the golf course. The photo below right shows 11 green on October 11th when the sun was much higher in the sky than it is now. The 11th green is in the same position to the trees as the boulevard is to our house; meaning in the winter the 11th green was shaded for most of the day, not allowing the sun to do its work. The trees shown were removed this fall and the 11th green is now almost completely free of shade.
The advantages of full sun on turf surfaces in the summer are well documented both on this blog and though countless university research projects. However, any turf manager in snowy climates will tell you shade is just, if not more, detrimental to turf in the winter. If the winter weather is warm enough that sun is melting snow then it is imperative for it to be able to due so. This winter the sun has been melting snow in mid-January, typically this happens at the end of March. Anytime the melting of snow is extended or suppressed by shade the potential for ice damage to our turf increases exponentially.
The tree removal completed this fall was done for a number of reasons, not the least of which was the elimination of shade from our putting surfaces."
