I have been trying to figure out what is wrong with my Bermuda. For background, I treated with headway G thinking it was possible fungal issue. I aerated thinking it was a compact soil issue a month ago. I’ve treated with fertilizer. Sprinklers work and I’ve done the tuna test. I officially have no clue what to do. It just keeps getting worse. The first picture was when I started trying to improve. Second is recent. It’s just getting worse. Any ideas on what this issue is???

(Firstly, a single experiment doesn't prove anything. It's just a good demonstration... Extensions have long since proved it)

Background:

Had a 10 day stretch with no rain or irrigation. My kbg was doing weirdly well, despite growth potential getting into the teens for several days straight... Darn clay holds water too well.

This section along the driveway was starting to wilt a bit faster because it's got a deep sand base from the driveway. So it's hot and dries out faster. Still green, but it was getting that dark dull hue of drought stressed grass.

This spot gets about 80% sun.

What I did:

Saw we had some rain coming the next morning. So I applied propiconizole, chitosan oligosaccharide, azoxystrobin, and chlorothalonil (for science 😉). Let it dry for a few hours.

Next I hand watered slowly for 20 minutes. Just a slow but really heavy drench.

Then I took a leaf blower and dried off the foliage and stems... This is the step that essentially guaranteed ascochyta would be favored over any other disease (assuming the fungicides didn't do that already), by kicking up any dormant ascochyta spores and avoiding the leaves being wet *all* night.

Rain came over night. Didn't check the totals, but it was plenty.

Next day was sunny and still warm. Gave it 2 light midday mistings to ensure the results weren't obscured by heat triggering actual dormancy.

Leaves began going more brown.

After the syringing, I did another bit of chlorothalonil because I assumed it was probably all washed off by that point.

More rain over night.

Next day, it was all a sickly gray.

2 more midday waterings.

Rain in the morning.

Next day (today) it's in full blown ascochyta breakout. Active lesions on everything, confirm ascochyta pycnidia under microscope. The effected area perfectly aligns with the spots that were hit by the blower.

Neat!

Hey folks so I have this front lawn and it was pretty green a few days ago but now it's becoming brown. I didn't change anything. Is it because of heat ? Water cycle is Monday and Thursday. I also water sometimes during the weekend.

One thing I noticed is that the sod patches that I put are not now becoming thin and brown. Like grass blades on the sod are thinning. Is that normal ?

Hello,

I over seeded last fall and things looked incredible in the spring but the grass was fragile. After the multiple heat waves and I left the water sprinkler on for 1 hour a week. It has gotten to this point and I want to know what I can do to nurse this back if possible. I got some milogranite to add but now I don’t even know what the point is.

The lawn in the backyard that get partial sun is doign great , this side gets the sun until 2 pm directly.

Last year my first year fine fescue had a ton of what was believed to probably be brome. We dug a lot out, and the grass is denser so there's not much left.

Now my first year fine fescue in back has this different looking weed. It's more upright instead of sprawling, and the root ball is smaller. It grows quickly, popping up above the cut grass since it's so upright. Is this just another kind of brome, or something different?

Assuming it's not an annual, I plan to try the glyphosate paste on the leaves trick.

I swear this stuff comes from the seeds.

Hi all,

I am currently looking for any assistance on how to improve my backyard grass. I have sir Walter grass and am based in Central Queensland Australia. It is currently winter where I am but the temperature is 25-30 degrees each day.

Below is currently what I am doing to improve my grass but I am unsure if it’s the best thing to improve my grass:
Watering every second for 20 minutes before moving the sprinkler to a different spot.
Mowing once a week.

I have done a bit of research and am looking at potentially doing the below to improve my grass but wanted to check to make sure that it’s the best thing to do:
Purchasing dog rocks as I know there are numerous urine burns in the garden.
Purchasing organic based top dress lawn soil and applying an even layer over the yard.

Please let me know anything on how to improve my grass!

Thanks heaps!

I'm in zone 8B and overseeded with superturf II last season but forgot to use mesotrione. I've been seeing a lot more of this weed this year... Can anyone help me identify this weed?

So, I mowed this area down to basically dirt but there was still 0.5-1inch left when I got done. I then cultivated it using a tool I got at Ace Hardware. I think the weed is Daligrass but the roots grow horizontally and not vertically if that helps any and they tend to be pretty long as I pulled a few spots out. After this I spread some seed on top and have been watering 2-3 times a day. Will this work I’m guessing not. What should I do instead? Is the weed Daligrass? Quackgrass? May need to zoom in sorry for the poor photo in advance.

I nuked and renovated my lawn with TTTF/KBG mix last fall.

The deep roots of the Bermuda I thought was dead have pushed it back through and created patches.

How can I gain control of it this fall and work towards eradicating it? I’m in Charlotte, NC.

Does anyone have any idea what is causing the brown spots on my lawn?
My buddy gets animal urine even though I do not own pets. It may be reoccurring becauseI this happened last year as well. But not sure if it was the exact same patch. This was green just a few weeks ago before the browning b

My back yard is PRG seeded last fall and has been dowing well all year but I now have some brown spots creeping in, I thought it was water related but have increased watering volume and still have these spots, thoughts?? In the Pacific Northwest.

I think I have a mix of grass types in my yard. Would like to know what I have to try and figure out a plan moving forward! Thanks in advance.

I am trying to get on a schedule and follow it. I’m based on Long Island NY. The app recommended me the following. Curious your thoughts?

It might be biased (or they make $$) on the product brand but I’m thinking I can buy a different product brand

I'm specifically asking for feedback on how I'm fertilizing my small lawn. I'd love to dial it in. Due to the size it doesnt take much cost or time. And easy enough to water through the summer. I'm actually quite confused tbh

As I side note, the attached is a before and after. A few weeks apart. All it too was 2 days of straight rain in my clay soil shitty Brooklyn soil to get disease. I'm addressing that. Whole lawn is looks like that now lol

4lbs of N/1,000

Questions

1. Currently have nothing scheduled for October but can't remember why. Especially if Fall is supposed to be the biggest push?

2. Curious about my next application for July. I had severe fungal disease and its looking a little rough right now so thinking maybe extra N would be good for now. Note: I did try a half rate of PGR literally right before I was hit by all the fungal disease so its def not outgrowing it fast or at all..yet...perfect timing :)

3. Flagship seems fine, doesnt push insane growth, feels moderate to generic things like Scotts. Open to other suggestions.

________

April
24-0-6 (Flagship, full label rate .27lbs N)

May
24-0-6 (Flagship, reduced rate .19lbs N)

June
24-0-6 (Flagship, full label rate .27lbs N)

July
Not sure what to do here, maybe it should be a stress blend (ie. 7-0-20) or maybe i can just keep using flagship since thats what I have on hand (.05N)

August
n/a - anything?

September
I'll be fixing spots so I guess i should buy a starter or maybe just use the flagship i have. (.27lbs N)

October
n/a

November
Flagship or some kind of "winterizer" blend

all adds up to about 4lbs/1,000 sq ft which is ideal for KBG. So I'm not tracking how some people have told me to just apply 3 times a year. I'm doing at least 6. yikes.

Any thoughts or resources is appreciated. I see lots of suggestions all over but I get a bit lost when actually trying to map out the year.
