@Powhatan I wonder how ORTHO Nutsedge can have such a long shelf life but when you mix up Dismiss they want you to use it in 24 hours. Think that's BS or is there some herbicide preservatives in Ortho products?
@mjh648 don't have a good answer for you about chemical separation during storage. Good question to post on the forum.

I see on the Dismiss (Sulfentrazone 39.6%) label it says "Use Dismiss Turf Herbicide spray mixture immediately after mixing. Do not store the mixture." That's what I do when I mix up concentrates, only enough for what I'm doing that day, nothing mixed stored.

If you cut it, does it look like a triangle base?

Yes, it has the triangle base cross section.

Those seedheads coming off the plant are interesting.

Google Lens is giving me different results but they all come back to sedge. False hop sedge, Wooly Sedge, Midland Sand Sedge all of which I have never heard of and some actually being listed as endangered plants. Interested to see if the seedhead firms up and grows larger.

I may have discovered what it is - Long-Beaked Sedge. It's one of the components of the wildflower seed mixes I sowed last fall. I'm guessing some of the sown seeds may have blown into the lawn. The sedges I took a pic of are next to a wildflower bed. Need to see what this sedge's seed heads matures in to.

Air temps on the way up, it was 94F today. Mulch mowed @ 3.25". Need to spray N-Ext RGS to help roots grow deeper.

Sprayed N-Ext RGS @ 6oz/M rate, to help roots grow deeper before the summer stress.

I've noticed in years past that latter half of May in my area when air temps and humidity are consistently higher is when fungal disease symptoms (mycelium and/or dark areas) begin to become noticeable. Last year during spring I applied .79#N mostly synthetic fast/slow release blend. This spring I applied .62#N some synthetic but mostly organic majority slow release. Also last year HOC was 3.50", this year so far it's 3.25". I'll go a little lower HOC if disease starts to appear.

To treat the fungal disease I lower HOC to allow more airflow, bag mow to collect disease blades, then spray neem oil on the target area to smother the disease pathogen. Some years ago I did synthetic granular fungicide preventative/corrective applications spending $$$ and alternating MOA for several months, still had disease and the lawn looked anemic. Maybe a foliar fungicide might of been a better approach.

KY-31 producing seeds. From one plant clump ~2 years ago to over 20 today. I use the harvested seeds to help fill the gravel road ditch and other areas in my lawn.

Looks great! I really enjoy your different perspective and maintenance style (especially the photos).

When my kids were young, I went to all organic (from a completely conventional program); which consisted of high HOC, no chemical pesticides (minimal organic pesticides) and overseeded only TTTF for lower maintenance (but I didn't skimp on fertilizer). Now, I have more of a hybrid approach across the board with more maintenance (but not high maintenance)...more of a best bang for the buck approach.

I've always been curious as to your philosophy. You seem to generally have a more naturalized approach, but do use conventional fertilizers and pesticides at times. With seeding clover and K-31, it seems that you look for more natural, somewhat bullet proof varieties that can coexist and keep each other in check, and can survive the scorching heat of summer with minimal-no irrigation. Am I in the ballpark with this?

Thanks. I try to capture things with the camera that I think people will find interesting.

You've hit the nail right on the head. :thumbup: :thumbup: :thumbup: :thumbup: :thumbup:

I'm just basically trying to do more with less by using the naturally available resources than relying on man-made inputs. Grass has been thriving for millions of years without man's "helping" hand.

Mulch mowed @ HOC 3.25".

First time trying sand/soil mix to level some low spots. Did a 50/50 mix of Sakrete Play Sand and Sta-Green Potting Soil. The sand had some small pebbles and the potting soil had some wood chips but both seemed overall adequate for what I'm trying to do. I used the back side of the leaf rake to spread and smooth out the mix in the grass.

Past two weeks received 0.31" rain with high air temps ~80Fs. 80s/90s with slight chance of rain forecasted rest of the month.

In the driest area of the lawn the clover is barely hanging on and the is TTTF checking out. The nearby oak tree is sucking up the soil moisture.

The rest of the lawn showing some drought stress blade curling.

Hot 90sF with high humidity coming next week. Grass has grown ~1.50" from last Friday's cut four days ago. Need a bog mow to lower canopy for good airflow and minimize fungal growing conditions.

Bought two bags of Scotts Natural 11-2-2 All-Purpose Lawn Food to try next lawn feeding.

Not much to do on the lawn except hand-pull orchardgrass weeds. Lawn mostly green with more heat dry stress areas appearing.

This is a Japanese Honeysuckle. It’s an invasive vine plant that is very fragrant.

There's some random blade yellowing appearing. With my soil's low CEC (sandy soil), I believe the yellowing is due to nutrient deficiency chlorosis vs a fungal disease.

Received 0.03" rain this morning, not very much but it registered as precipitation.

A bit more shade in the back which probably helped the grass grow taller there than the front from last cut 6 days ago @ HOC 3.25". High temps 90s past week, 101F on Sunday, according to a local Weather Underground station.
