Anyone know what this stuff is?

[macoop]

This stuff is taking over my yard and I don't know what it is or how to kill it. Any suggestions?

Looks like Poa annua grass, also known as annual bluegrass, is a annual weed that is commonly found in lawns, but can be found in gardens as well. It is rather difficult to control because the plant will produce several hundred seeds in one season, and the seeds can lay dormant for several years before sprouting.

The identifying characteristic of poa annua grass is the tall tasseled seed stalk that will typically stand up above the rest of the lawn and becomes visible in late spring or early summer. But, while this seed stalk can be tall, if it is cut short, it can still produce seeds.




Poa annua grass is typically a problem in the lawn because it dies back in hot weather, which can make unsightly brown spots in the lawn during the height of summer. It also thrives during cool weather, when most lawn grasses are dying back, which means that it invades the lawn at these susceptible times.

Controlling Poa Annua Grass

Poa annua grass germinates in the late fall or early spring, so timing of poa annua control is critical to being able to effectively control it.

Most people choose to control poa annua with a pre-emergent herbicide. This is an herbicide that will prevent the poa annua seeds from germinating. For effective poa annua control, apply a pre-emergent herbicide in early fall and again in early spring. This will keep the poa annua seeds from sprouting. But keep in mind that poa annua seeds are tough and can survive many seasons without germinating. This method will work towards reducing poa annua in the lawn over time. You will need to treat your lawn for many seasons in order to rid it completely of this weed.

There are some herbicides that will selectively kill poa annua in lawns, but they can only be applied by certified professionals. Round-up or boiling will also kill poa annua, but these methods will also kill any other plants that they come in contact with, so these methods should only be used in areas where you wish to kill plants on a wholesale basis.

Just great. Sounds like I need to rip up my lawn and start over.

Just build one of your stone blinds on top of it. It will look great and keep you preoccupied.

I gave up on having a nice yard after trying for forty years to have one. When it doesn't rain the yard dies as our well water is not fit to irrigate with. When it does rain, millions of weed seeds are moved from the pasture into the yard. We are on the side of a hill and I have done earth work to divert the water flow, but it is not totally effective.

Now, if it is green and covers the dirt it is pretty much tolerated in the yard. We just mow short and don't worry about it much.

Every spring I hit my yard with "Ortho Weed B Gone" Weed killer. The one with the yellow handle. It is something like 8.5% 2-4d and hooks right on to the hose.

Water the yard and kill the weeds at the same time

Your best bet is the pre-emergent during the fall and winter. If it's growing, you can kill it with Image.

Not sure it it dies off quick once it starts warming up.

crab grass need MSMA sprayed on it.

Ha.....If I didn't live in town that would be an option. My neighbors might get a little ticked if I did that.

In my yard I am fighting a large amount of junk grasses and weeds. I spray round up or one of the generics every spring before my Bermuda turns green. It will not kill anything that is dormant. Here if I spray in the middle of march and kill the clovers and rye. It takes several days to work due to the cooler Temps but once the Bermuda starts it doesn't have to fight through all of the junk I don't want anyway. I will then spray msma or 24d in the summer.
