Diffrent colors of grasses on greens?

That's RIGHT! Our greens are predominantly poa annua greens (annual bluegrass). Predominantly meaning almost 100%. We strive to maintain a true roll throughout the day as well as an average green speed of 10+. Knowing this we want to inform you that although we mow, verticut, roll, topdress, apply plant growth regulators, there are 20+ different strands of Poa annua grass growing on are greens. This means that given the right temperature there are certain strands that grow when its cool, hot, wet, dry, etc. Optimum temperature for poa annua grass is not to exceed 85F ambient, and 75F soil because it will start to wilt if it does not have enough moisture in the soil. We are constantly checking greens everyday even 3 times a day for this. As we get more consistent with warmer temps you will see many shades of Poa annua. One grows more than the other and vice verse. After a mornings mow, roll, etc. this is when you will see the most consistency. As the day progresses so does the turf. Inconsistent growth, slower speeds, and not a true roll. Bottom line: The more we mow, groom. roll, verticut, topdress, and apply growth regulators it will "trick" the plant to be as consistent from morning to afternoon. Warmer temps equal inconsistency, cooler temps equal consistency.
