During the winter each year I seem to get more Poa annua in my zoysia lawn. How do I reduce the Poa annua in the first place, and how do I control it once it's in the lawn?

We have zoysia grass in our yard and it is always the last in our subdivision to turn green and the first to turn brown. Right now(April) it is brown. Is there something we can do to make it really green for a longer period of time? We really don't do anything to it other than mowing.
Unfortunately, zoysia grass is known for this in cooler areas. You can try fertilizing and de-thatching to make for a healthier lawn, which may prolong how well it performs.
What is the northern limit for Zoysia grass?
You can also grow Zoysia in Zones 5 and 6 but it will not turn green until June in those areas.
While there have been same varieties that have been developed for northern climates, such as the Zoysia Japonica or the varieties of ‘Meyer’ and Emerald’, it is generally not suggested that this warm-season grass be planted up north. At the first hint of cold weather, even the cold weather varieties will turn yellow. It is not very appealing to most people to have a brown lawn for most of the year.
We had Zorro zoysia installed about 30 days ago. We are experiencing many brown spots in quite a few areas. We are concerned about this situation since we live in San Antonio, Texas and had to replace the dead St. Augustine lawn. Please advise us on the watering schedule for this grass, including the length of time for each application and the frequency as well as any other suggestions that you may have. My current watering schedule is two times a day for five minutes -late morning and late afternoon.
I would water once or twcie a week. This creates a healthier grass as the roots grow deeper. The amount you water should be between 1-2", depending on how hot it gets in your area. Based on your area, 2" twice a week is appropriate. Once it gets above 90F, you can up this to three times a week.
My neighbor has zoysia grass, which has jumped his driveway and it now growing in to our front lawn. How can I get rid of it?
Zoysia is extremely difficult to get rid of. You can either mow it down as close as possible to the ground and treat with herbicide or remove the sod with a sod cutter. Small areas or patches of Zoysia in a lawn can be treated with a non-selective type herbicide, such as Round-up. However, this type of herbicide can potentially kill any plant it comes in contact with. So be careful when spraying around plants you want to keep.
For best results, apply the herbicide when the Zoysia grass is still green, actively growing and not dormant or under drought stress. Since Zoysia grass may regrow, more than one application will probably be needed.
I have unidentified brown colored grass growing all over my lawn. They are about 8 inches tall in spots with seed pods growing on them. Is this the way Zoysia grass begins to spread and germinate? They started to grow in early April. Should I let the seeds continue to grow? I planted my plugs about two years ago, and now I see some growth. I have purchased Zenith seeds for another section of my lawn and already placed 8 yards of topsoil down. I am trying to shorten the length of time for my Zoysia to grow over my entire lawn. Am I going about this the right way?
I suspect the grass you see is poa annua, which is a cold germinating grass that would have seeds at this time. This article will have more information:

Planting the seeds should have it take over faster and the topsoil will help them establish well.
