It is late spring, and we have been getting a lot of common phone calls of people asking us how to get rid of this weird looking fuzzy weed. 99 times out of 100 this funny looking weed is not a weed at all. It is usually bluegrass going to seed. Kentucky Bluegrass is the most common type of grass that you will see in the Boise/Meridian/Nampa area, so if you haven’t seen this problem on your lawn, you have probably seen it at your neighbor’s. Most often people will notice it a few days after they have mowed their lawn. Kentucky Bluegrass is a unique plant because it can spread and germinate its posterity through its seeds as well as through its rhizomes. Interestingly enough this plant can send its rhizomes around the dirt of your yard in a direction that is parallel to the surface of the lawn and will then occasionally produce a node that can grow a new blade of grass.

When does Kentucky Bluegrass go to Seed?

Kentucky Bluegrass going to seedDuring the late spring when the outside heat is warming up the temperatures in your soil are doing the same thing. When the average temperature is around 60-65°F the seeds will start to germinate and pass into the seed producing phase of the grass’s life cycle, causing the fuzzy looking appearance that worries so many home owners that they have an infestation of weeds growing in their yard. Another thing that adds to this “problem” is that when a grass is going to seed, that process requires energy from the plant, and since there is only so much energy that a plant has, it has to steal that energy from somewhere. Usually the grass will take that energy from the processes that keep your lawn thick, so not only will your grass have the fuzzy looking seeds on the top, but more than likely it will thin out at well.

The best part about all of this is that since it is a naturally occurring process you do not need to do anything to fix it. Some people will try and lower their mowing height to fix this, others will try and put some weed killer or fertilizer on their lawn to fix it. Don’t do any of these things. Nature will take care of all of it on its own. You just have to have a little patience, and realize that only healthy grass is going to go to seed, so if you have this problem every spring, then you also have healthy grass and you will be able to enjoy that for the rest of the summer. Generally the germination phase will last a week to a week and a half, and Bluegrass will only go to seed one time every year, so you won’t have to worry about it again until next May or June.
