I would recommend a soil structure "jar" test. Instruction can be found here: https://aroundtheyard.com/index.php?option=com_content&view=article&id=70:soil-management&catid=9&Itemid=117 If you have a clear soil horizon at ~2 inches, it is likely worthwhile to jar test above and below the horizon to...

What is the percent cost increase on the total project going with the more expensive seed? It might not be as much as you think.

You can have a good lawn without irrigation if you have perfect conditions for a good lawn such as perfect soil, the correct type of turf, the right temperatures, rainfall and management. That won't happen every year. Give it a try. The worst thing that will happen is that you will have a dead lawn ...

You can use grains at pretty much any time. Alfalfa has a natural growth hormone, Triacontanol, so you may want to limit its use to monthly at most. Alfalfa is also among the more expensive grains. Soybean meal is less expensive and has a higher nutrient content and is a popular choice. Commercial o...

I would increase the seeding rate in areas with no grass coverage. Essentially treat them like new lawn establishment in the rate. I don't know the rates for TTTF off the top of my head, but (I think these are correct) if the new lawn rate is 8 lbs/1000 and the overseed rate is 4 lbs/1000, then you ...

People use it, or something like it, on Zoysia in the St. Louis area all the time to cover winter dormancy. I personally hate Zoysia, so don't have any personal experience. My city also uses a green paint/dye on common areas that go brown in the summer.

Looks like fungus as there are definite lesions on the blades. It doesn't look extensive enough to require an overseed. If you have sandy soil, consider watering 1/2 as much twice as often. Instead of trying to get 1 inch down on Tuesday/Wednesday, for example, apply 1/2-3/4 inch to the whole lawn e...

That south facing hill is going to be hell on any cool season turf - especially if it gets sun from 10:30 on.

I think the issue is determining why the current lawn isn't performing. It may be much better with a change in management without the need to renovate.

Alfalfa has a touch more nutrients than clippings. It also contains a natural growth hormone good for grass called Triacontanol.

Household vinegar (like what you use on your salad) is unlikely to be effective at killing plants - at least it never worked for me. Horticultural vinegar is a much higher concentration of Acetic Acid (~30% vs ~5%) and will work better, but is also potentially dangerous. You don't want to eat it, an...

PGRs definitely can make diseases worse - mostly, I think, because they slow the ability of the grass to grow out of the disease and recover. Add in a new lawn that is more susceptible to problems and it just compounds things a bit.

That last line should read "0.4 oz", not "4 oz". Typo. My bad.

I edited your original post for you. It prevents misinformation from propagating if someone finds it with search and doesn't have the context of the whole thread.

Propiconazole is a systemic. It can be absorbed by the roots and will be transported up to the leaves. You should be fine as long as it wasn't washed past the root zone. Fungicides won't bring back dead or brown turf. You will need to allow the damaged blades to grow out before the lawn returns visu...

I have never found syringing to be terribly useful on my lawn. That may be because of the humidity so it may work better in dryer climates.

I always used a hose end sprayer for Serenade. Accuracy is not critical. I use a backpack with a calibrated fan tip for Heritage. Accuracy matters a lot more at the much smaller doses of Heritage.

Daconil does not have a significant growth regulatory effect, unlike Propiconazole. I would be surprised if you saw an effect on growth rate.

What type of lime (brand and/or label info), over what area and how much did you apply? How much fertilizer, what was the N/P/K (should be on the label) and over what area was it applied? How do you know you are applying 1 inch of water? I'm not trying to be condescending, but most people have no id...

What was there before the renovation, and how did you kill it? Had you overseeded that area in the past before the renovation. If so, when did you overseed and what did you seed with? I'm not any kind of expert on PR, but that doesn't look like KBG seeding. I'm leaning toward some undesirable that s...
