What's the easiest, most effective way to add St. Augustine grass to my lawn?

I already have St. Augustine, but I had some MAJOR weeds this year that I've been treating. I would like to come back in the areas that are bare and add some St. Augustine. I understand that they don't make St. Augustine seeds. So, is the easiest way to do this, just to buy some pieces of sod and dig up a little dirt in the spots that I want it and then put the sod down in that spot? I was thinking about just laying the sod down without digging, but it seems like that would make uneven/high spots in my lawn. What do you lawn guys recommend?

Yes, dig out the spot so when you put the sod down it’s level.

Or just water those spots a lot and the st aug will creep in by the end of the summer. You will need to water a lot with the sod as well.

Can I checker them like plugs to save a bit on money? If I water it really good...the runners should spread fairly quick right?

Yes that’s how I did my yard after Katrina. Lots of watering.

I had the same issue and used plugs every 2 ft in the back yard. I watered heavily and the grass spread quick.

I will say though that it depends on the soil. I had extremely sandy soil (almost pure sand) so the grass spread easier than in compact, clay soil.

Is it a significant portion of the yard or just random spots?

In the back yard, it's a pretty big portion in the center of the yard. I'd say about 10ft wide x 40ft long which had a ton of weeds like thistle, dandelion, etc. The front yard has more random spots. I just sprayed the entire yard earlier this week, so I was going to give it about 30 days to kill everything, then lay down the sod patches in spots.

I would plug the front and sod the back then if I was in your shoes.

Would probably just roundup the entire big section in the back, give it a bit, then rake and sod it up.

Plugging in the back would definitely work, it would just take longer. But if you're patient (unlike me) you shouldn't have a problem with plugs. You would just have to watch for other weeds attempting to fill while the plugs spread.

Good points. Another thing to think about is shade level. If it is in full/mostly full sun, it should spread quick. If it is part shade/dappled shade, it will grow, but will grow much more slowly. In such a shade situation, I'd go with the sod.

If you use plugs, take a few minutes per plug and loosen up the sod/root system on the bottom. They can get really compacted in those plastic trays. I used a handheld 3-tine fork tool; the plugs rooted/established and started spreading much quicker that way.

You’ll want to get an action hoe and scrape the area to clean out the weeds and crest a nice edge. Don’t plant the sod at ground level. Always make sure it is 3/4 of an inch higher so it can settle.

Since you already have St Augustine in other parts of the yard. Buy a bulb planter and cut plugs from the good part of the yard and transplant them.

Cut pieces of your healthy grass and plant them in the bald spots.

because st. augustine spreads with runners, you will likely kill a much bigger area than the area you actually spray.

Many years ago when I was just a kid my mom decided she would like a St. Augustine lawn, so we'd head out with shovels and cane knives and find houses that were abandoned that had St. Aug lawns and we'd edge along the sidewalk and take the grass that was growing over the walkway and getting scraggly along fence lines.

We'd take them home and dig spots in the yard and bury most of it under the soil and keep it well watered. By summer's end we had a pretty good lawn of St. Aug and in 2 years, it was a complete lawn.

Runners, that is all it really takes, along with the patience to water them until it all fills in.
