The Weather's Slow Start

Although technically spring is here, the cold weather confirms it is off to a slow start.  This March has been extremely cold with the high temperatures only averaging 36 F.

The snow has finally melted from the greens.  I'm pleased to report the turf has come out from winter free from any winter disease or ice damage.  The turf remains dormant, as temperatures haven't been warm enough to initiate any growth.

If you remember from previous posts, growing degree days or GDD are a way to measure heat accumulation.  The growing degree days this year are lagging 458 days behind last year's rampant pace.

The data below looks at where the GDD were on March 27th over the past five years.  As you can see, we are off to a slow start.
 
3/27/13 GDD =  41
3/27/12 GDD = 499
3/27/11 GDD = 105
3/27/10 GDD = 232
3/27/09 GDD = 170
