Short story.....new construction in a recently built subdivision. Many of the houses are having trouble with sod taking hold and growing properly. I have not had such a problem except for one section of my lawn (about 20%). One neighbor mentioned he was going to apply a liquid aeration product to break down the clay. Wondering if this works or is snake oil.

I have St. Aug, but many of the homes are having the same problem regardless of the grass type.

Any experiences with these products are much appreciated.

TIA

Mechanical aeration with a core aerator. You all could go in together and rent one or maybe get a deal from a lawn service company that does this if they can do several or more lawns on the same trip.

It's not snake oil, but it's very inconsistent and relies heavily on the very specific soil type, existing moisture content, tenps, etc.

Your a lot better off using a mechanical aerator to solve issues, and try liquid for bi-annual maintenance

As the other HG brothers have pointed out. Core aeration is the way to go. For St Aug I would suggest aerating and top dressing with compost.

I just went through this exact same issue. The real problem is the clay that’s sitting underneath the sod. The grass can’t root because the roots can’t penetrate what the builder left behind.

The liquid aerator will help water flow through the clay layer but it’s not going to break it up enough for the rooting to take place. You need to core aerate, top dress with 50:50 black kow/sand and do this repeat again next year.

is it too late to core aerate?

Thanks for all the replies. Figured there was no real substitute for aeration.

The grass is doing fine right now and it's been down about 8 weeks... Wondering if aeration in the fall might be a better time or is it advisable to do it when the grass is actively growing?

I’d do it asap so it has time to root and establish before fall or youll be fighting the same battle next spring.

Is store bought bagged compost loaded with weeds? I worry about spreading it for that reason, interested to hear others experience…

I aerate ever April/May depending on when I feel like my aeration truck over to my house. Aerate when it’s growing.

To the compost question. I use Mason sand because I have Bermuda. I don’t use compost because bermuda is not prone to fungus which st Aug is. Compost has been shown to help with fungus. I would prefer to see what I am buying. Granted I can’t see weed seeds but j can see the facility and see how finely screened what I’m buying is.

I tried regular compost and composted manure (black kow).

It was about the same price point and the areas with black kow exploded with growth while the regular compost and sand improved, but more modestly.

I can’t recommend the manure option enough it was like a cheat code after a ton of other things failed.

This thread got me to test out liquid aerate. I applied on a section of my lawn where some spots need to be aerated and others do not. It’s been a week and there’s a slight difference in the parts that did NOT need to be aerated, and zero difference in sections that DO need to be aerated.

I used the screwdriver method. Just my anecdotal evidence. Screwdriver measurements are obviously not scientific

Gypsum will loosen clay soils, they sell pelletized gypsum at nurseries for this specific purpose.

That had nothing to do with what you applied. March isn’t even green up time. That was a result of dormancy vs out of dormancy.
