CDGA Weekly Update - May 20

May 20, 2011 Scouting Report
Clear Skies and Sun! Bentgrass is Green, Bentgrass Seed Germinates, More First Dollar Spot, Waitea Progresses, and Tim's Research Work for 2011

Chicago/Northern Illinois Update: Derek Settle - Weather Blog
Wed 50 low /60 high and Thu 46 low /73 high. A pair of nice days and Friday is just as nice - warmer nights and how about full sun? It means this season has just turned the corner and is in a direction that creeping bentgrass likes (i.e., bentgrass needs average soil temperatures at 2 inches to stabilize at about 55 degrees or higher for good growth). Also, good germination of seed has begun and continued to accelerate into this week. Areas injured by season 2010 that were without complete recovery are now looking better - Chicago's inner roughs especially hard hit.

It turns out low-mow Kentucky bluegrass was also slow out of the blocks in 2011. The negative impact of repeat frost events in May did not help. Next up, we will try and experience good weather for June? June is arguably our most important month of root/shoot growth given what July can bring cool-season turf in Chicago. Such as, repeat daytime highs of 90+ degrees and, during a hot and humid summer, midsummer physiological decline that begins as July transitions to August. But wait, it's still May and this week felt like heaven on earth = clear skies and sun!

Have a great weekend, and exactly where's the sun?
