Is this scenario happening to you? It's late spring and it has been 2 or 3 days since you have mowed the lawn. It looks pretty great except you ask yourself… "What is that fuzziness on the top of my lawn? Is my beautiful, green lawn getting some weird weed infestation?"
Most likely, no. Just like we see our trees and shrubs going through their annual reproductive cycle (i.e, seedlings flying around everywhere!) it is the time of year that annual Bluegrass goes to seed. The top of the blade will begin to flower and from a distance, looks like a fuzzy weed has overtaken your lawn. This seed is not viable, just a phase in the life cycle of the plant. Be patient and keep mowing as normal and soon this "flowering" phase will pass.
