This is the grass sorry I cannot for the life of me figure out how to put a picture in the first post I create on garden web using my phone.

I'm not sure you can edit an old msg and add a photo, but that doesn't matter. I'm sure you can look at the grass itself and see what you're looking at, but when you take a picture of a lawn, the best ones are taken in the shade or overcast day. There is too much contrast in the picture to see. Would you mind taking them again but with something blocking the direct sunlight. Here's an example of the difference.

To move toward an answer to your question, I don't see any crabgrass in the picture. Where (in PA) do you live and what kind of grass do you have?

Crabgrass does not grow taller than other grasses. It is a very low growing grass. There might be some nutgrass/nutsedge in there. I'll add a picture of that for your reference.

This stuff does grow tall and fast. If you feel the plant near the base it will feel triangular. That is a sure sign of nutsedge. There are two products I am aware of which will kill it. One is called Sedgehammer and the other is Image for Nutsedge.

When cloudy ull get another. Thanks!

Not sure if those pictures are any better and I did find this seed I'm pretty sure I put this down and some sort of Scots I have no idea that's what I am seeing.

By the way the second picture is where it's the worst and where I aerated and overseeded. It's where the snow ends up when we snow blow our driveway and I think that's what killed most of it last year plus the drought last yearbefore that...not sure but it's dying out again this year. Except for whatever that light green grass is!

Sorry to trouble you again, but now that you're getting really good at taking pictures, can you please take another from about 6 inches away? And if it is not in focus, take another picture.

Also, while we're looking at your lawn, what is your watering schedule? How often and for how long do you water? Have you fertilized this year? What did you use and when?

Sure . This evening I will. When I zoom in pics they seem good to me but I will add more. Fert in spring with haltz and in summer with weed and feed. We had so much rain I gave it a second shot of straight fert early on. The photo is of the worse area of my law just off my driveway. I overseeded here last fall and this spring. It always dies out here but I never had that lighter green taller thicker grass before unless that is Kentucky blue or whatever crap was in the Scott's I put down. No watering schedule...when it rains. We have had a lot of that this year in Eastern PA.

“It sounds like what you’re seeing could actually be crabgrass or coarse fescue. Both tend to look lighter, with wide blades, and they grow taller and faster than your main turf. Because you overseeded, it’s possible the seed blend had some of those grasses mixed in—or crabgrass just took the opportunity to fill in bare spots.

Since you’re in PA and had a very rainy year, crabgrass pressure would be higher than usual. If it pulls easily and has a lighter stem, it’s likely crabgrass. If it clumps and is persistent, you may be looking at a fescue variety.

My suggestion:

• In late summer/early fall, use a pre-emergent next spring to block crabgrass.
• Overseed again this fall with a high-quality cool-season blend (look for Kentucky bluegrass, perennial rye, or turf-type tall fescue).
• Mow at 3–3.5″ to shade out weeds.
• Spot treat crabgrass if needed.”

Thanks..the stuff pulls out of the ground pretty easily. So crab grass feed this fall and next spring? I should reseed this fall again?
