I just put down my first application (1/2 rate) about a week and a half ago so I can't really report on much yet. I have Tifway 419.

Make sure to add some iron to your application to help with possible tip burn.

I planned on it! Do you mix? Add a surfactant?

I did not add a surfactant. I do not recall that being something recommended with PGR?

I added NutriSolve (Ron Henry product) which has 2% iron in it as well as other micronutrients.

Did you do full rate for your first application?

I haven’t done it yet. Strange weather, early greening followed by a stall, I have been trying to aerate the last 4 Saturdays and it rains, I’m sand leveling May 31st and June 1st so I want the grass to grow through. 46-0-0 should expedite that.

Up, down, all around. 21% ammonium sulcate to push growth. Can grow vertical so must grow horizontal

Editing this thread title now to be more general.
Did you start PGR last season though? I saw a thread from last year where you talked about it.

For Zoysia, it’s rated at 11 oz an acre.
You’d probably start with 6.5 until you get comfortable with it.

Label rate could stunt growth for quite a long time, or so I’ve read.

T-nex is almost $1.25 per oz. When you buy a gallon. Roughly $160.

So label rate will run you a little less than $13.75 per acre per application. Or, about 31 cents per thousand sq ft per application.

Usually apply every two weeks.

My own update for St Augustine.
I suck at spraying, but that tells me that it clearly works as some areas are growing faster than others. I pulled this stolon.

When is the best time to apply?

---

I believe it is 4 hours before a mow or 1 hour after a mow.

I wouldn't apply it right after scalping - I'd wait until your turf is filled in and is actively growing at a level you want to maintain.

That NutriSolve works great. I bought some from Ron last year. I tried his new blend of stuff similar to NutriSolve that he worked with Anderson’s on. Seems like the NutriSolve worked a little better.

OP I haven’t tried what you are talking about, but I did buy some granular fertilizer from Ron Henry and it did turn it green during last summers heat wave and it definitely didn’t need to be mowed as often which was nice. Ron specifically told me it wouldn’t make my grass grow too fast. I don’t have time to cut my grass 2-3 times a week. I actually just set my cutting height higher and my yard seems to be okay with topping it off at 3”. That breaks a lot of these so called cutting height rules but I’ve done that for 35 years or more. I travel a lot for my job so I do the best I can on the yard. It’s not cut short but it stays nice and green.
