Why is new perennial Rye grass turning yellowish?

I’m also in MD.

My PRG is starting to yellow as well. Dormancy is coming.

Judging by the leaves in the lawn, as well as the dormant looking lawn across the street, I’m going to guess that it’s turning yellow because we’re in the middle of fall, and your lawn is starting to go dormant.

You yourself had a post 2 weeks ago where you talked about the last cut of the year.

You’re located in Maryland, and a quick Google search says that it is in the mid 50’s to mid 30’s the next few days, and in the 30’s and 20’s later this week.

I mean, is it really that hard to understand dormancy?

@Skylar
It’s wild how difficult it is to understand for people that are obsessing over their lawns to the point they frequent this subreddit and post in it.

The lack of critical thinking in society or ability to search for an answer before posting is truly wild.

@Skylar
I feel this is a “look at how nice my yard is but I don’t want to sound arrogant” post, disguised as “why is it turning yellow?”

Where do you live? How much rain have you been getting? What’s your watering regime? What have soil temps been?

:smile: good eye

Because winter is coming.

Window reflection? Is this facing West? Or it could just be dormancy, as others have suggested.

It needs to get pretty cold for it to go dormant. This kind of grass likes to eat; I dare say it needs a good fert and/or water.

OP is in Maryland. Forecast this week is anywhere from mid 20s to mid 50s.

In short, the lawn is going dormant.
