St. Augustine lawn rehab advice
Posted on 5/11/22 at 9:50 am

Back story: A little over a year ago, I brought in a load of dirt to fill in some low spots. My intention at the time was to fill in my low spots and come back in a year with mason sand to level. The dirt I could source at the time was fill dirt. I wanted top soil, but my local trucking companies only had river silt and fill dirt on hand, and I definiatly didnt't want riversilt. The dirt had a good amount of clay in it. I did what I could to break it put as best as I could. It also brought in some dallisgrass, a little crab grass and some nutsedge. All of which I been fighting since.
Present day: As previously stated, I intended to bring in mason sand to level a month or 2 ago. But I decided not to because I dont think my lawn is really ready for it yet. The areas that I filled are now mostly bermuda with a mix of the previously mentioned weeds. My St. Augustine hasn't really attempted to spread into those areas much. The dirt seems pretty hard as well. Where do I go from here?

Kill all weeds with heavy dose of glyphosate, multiple sprays if required, lightly till area(s), complete leveling with mason sand, and place St Augustine sod in bare/leveled areas.
You didn’t say large the area(s) are, and I know this is the most expensive approach, but many of us, have been down this road before, looking for the least expensive way to do this, but short of sodding these “bare” areas, you’ll continuously fight weed issues, common Bermudagrass for years, waiting for the St Augustine to fill in on its own from the surrounding area and at the end of the day you won’t be happy with the time and effort it’s going to take for StAug to fill in on its own.

I don't have advice specific to your concerns, but I had a similar problem. I hired TruGreen to get things under control, and it was a huge mistake. They killed my entire lawn. So, I'm posting here just to make sure you don't make the same mistake I did.

@TSmith: Thanks for the heads up
@CrawDude: Its roughly (8) 50-60sqft areas in a ~9000sqft front lawn. After killing the existing vegetation, would attempting to transplant plugs from healthier areas in lieu of sodding be a waste of time?

I wouldn’t say it’s a waste of time, it will work and I’ve, and many others have done it, but I’ll be honest, you’ll continue to fight weeds on a larger scale until the areas fill in with St Aug. Given the cost of herbicides and your own personal time, is it worth it? Only you can answer that.
8, 60 sq ft areas is 480 sq ft, is for all practical purposes really 1 pallet of St Augustine, 450 sq ft. It’s been about 1 1/2 years since I bought some St Augustine and then it was $250 a pallet, I suspect somewhat higher today. If you have access to 1/2 ton pick up, you can put a pallet in it to avoid a delivery fee.
You won’t/shouldn’t use pre-emergent, and very limited use of post-emergent herbicides for 3 or 4 months while either sod or plugs are becoming rooted and established (that info is clearly stated on just about all herbicide labels) which again provides an opportunity for weeds to be present. They’ll be fewer weed issues with full coverage sod compared to plugs. But plugs will be better than letting the areas fill naturally from surrounding lawn.

I've had good success with Image Southern lawn weed killer and using sand for low spots and bare spots.

Common Bermuda SUCKS! Been fighting that in my lawn for 4 years. Even after going nuclear on it last summer.

I bought one of the "pro plugger" devices this year for the same reason. It let's me transplant from the good areas of my yard to the bad pretty easily, and for free. I got the wife and kids in on the job, so I've been increasing the density of the plugs. Can't comment on long term success, but the plugs are doing well so far, and beginning to "run".

I bought one last year. I took about 500 plugs from my dad's yard. They didn't do well last year but this year they're really starting to grow and spread now. It's also kind of therapeutic to crack a beer and start plugging after work.

how long do you have to wait before sodding? tia

Pretty much “immediately” if using glyphosate - it doesn’t have a residual effect, so after the “weeds” die, and one tills, you can lay sod or plugs.

As said, if you want it done this summer you can have a nice sodded lawn in 30 days. Otherwise you are realistically looking at a 2-3 year project. Drop some pre emergent, get some post emergent spray, and round up with a paint brush for the bigger/ hardier stuff.
The best way to allow St Aug to outgrow everything is to cut your yard long 3.5-4 inches and get your St Aug healthy. It will eventually start to crowd everything out. You gotta be patient though.
Nothing wrong with plugging also. I’ll buy 2-3 pieces of sod and use a machete or hand saw and make 20-30 plugs per piece of sod. Lot cheaper then buying actual plugs.
