Please help with identifying

Post by Snaclerio11 »

So I’ve been going back and forth with a lot of people and have not really received a solid answer on if I have poa triv or orchard grass. I did a tenacity app on the 22nd no surfactant and I have a lawn that’s bleached. I don’t want to miss the opportunity to kill off the lawn for a renovation next year. Should I do a tenacity app with surfactant to light up the problem areas again ? Thank you in advanced.

Poa triv or orchardgrass removal in a cool season grass is the same: dig it out with roots or spray glyphosate to kill down to the roots, then sod or re-seed.

You might be able to send in digital samples to your state extension office so they can ID the plants.

I'm in the same boat as you - and that boat is fully of frustration and misery.

After 2 years of a beautiful dark green carpet-like yard, it's now blotchy with poa triv. I'm torn between nuking it and looking at brown dead spots all summer or waiting to nuke and re-seed in the fall.

I dont think thats Orchardgrass. Orchardgrass is a really really coarse bladed grass with a flat stem and its blades have a bluish green color.

What you have looks like Triv to me. Your stems are rounded and have that crinkly appearance of Triv in that last photo.

@Snaclerio11, that does look like Triv to me...
Front: Northern mix - mostly TTTF, KBG, TTPR. Back: Firecracker and Bullseye TTTF with America, Rugby 2, Bewitched KBG. Upper Side: Mostly TTPR, KBG. Lower Side: similar to front. Low-input: TF/FF, KBG, PR. Always seeding somewhere or fighting Triv.
