This grass weed has tried to take over my beds the past few years. What is it and tips to get rid of it? Thanks!

That is a sedge. I wish I knew how to get rid of it.

Get a dedicated Nut Sedge killer.
It will take more than one application, or years.

Can I smother it?

Maybe, I have not tried that. Part of the reason it is so difficult to eliminate is that it grows from a little, practically immortal tuber or "nut" that can be deep under ground; when you pull it up, you ordinarily will not get that part.

I just pull it out whenever I see any shoot up in my garden. With a taller size like yours, a trowel will do the job.
I avoid any chemical weed killer/pesticide in my garden.

NO, I have had it for years.
I will poison it and think it is gone.
A year or so later , POOF, there it is again in the same location.
You pull it , then the bulb will put out two or more where there was one.
My other half pull out a large area before I could poison it, is one reason I have been fighting it for so long.
You can take a spray bottle, bend over and put drops or droplettes on on individual or a cluster , if you do not want to do a general spray.
It MUST BE a weed killer dedicated to Nut Sedge or you are wasting your time.
This is all from years of experience.

I use a dandelion weeder to remove them. It's a long tool with a little v shaped notch on two points at the end. Works pretty good getting the "nut" out. It can be pulled by hand successfully if the soil is wet.

@RpR, do you know which chemical you used? I know there are several, and I thought they had to be applied to the soil to get a pre-emergent effect on the dormant tubers as well to be effective.
I've been pulling by hand for years but always lose the battle once it starts getting really hot outside and the sedge likes it more and I like it less. I'm looking into alternative options now. Glare

I use Ortho Nut Sedge killer most often, but if you check online there are a few .
NONE of it is cheap..

And in my experience, none of it works long term. The tops die back, but the nut does not.

Nut sedges love wet ground! I didn't ever see it in my neighbors lawn, until she decided to soak it... then the sedge popped up all over. Working on freeway landscape it was always in low spots, ditches, and places that didn't drain well. That "nut" is really like a bulb. It can lie dormant until the water is right for it to grow. When that neighbor moved , I never saw the sedge again because the new owners never watered at all, and eventually put in astro turf. Hilarious!
