Cool Season Grasses in Full Flower

Cool season grasses across Minnesota are now in full flower. It’s June 14 and grass pollen is in the air! Occasionally a homeowner will ask what is happening to their lawn, if they get a bit behind in mowing, bluegrass will go to seed quickly. Grass flowering stems turn brown and die after flowering, but the leaves and non-flowering culms remain green and growing.

 

 

 

 

 

Smooth bromegrass, Bromus inermis, is common throughout the state and is considered a weed.
