I live in San Antonio, Texas so the temps are way hotter. With your chart and temps between 95-100 every day it says i would need to reapply in like 10 days. Does that sound right?
Sorry for the delay in response, I had to figure my own stuff out. I’m experiencing the same conundrum as many of you with this GDD calculation. The GDD formula works great if the temps are within the growing rage. When we start pushing into the summer with the high temps, I have learned that I need to adjust a bit. Let me explain, the base temp used in the GDD is basically the minimum temp at which the plant starts growing. The issue I experienced is with the high temps during the day, I was calculating very large GDDs, causing me to apply the PGR far to regularly. After reading a few studies, I found that farmers adjust their max temps based on the crop. I know that my max growing temp for my perennial rye is 87 F, so when my temps go over that number, I use 87 F as my max temps. Example, let’s say the today’s temp range is 97 F - 66 F. Using what I know now, the temps I enter in my GDD calculator will be 87 instead of 97 which will give me a far lower GDD number. Currently, with the temps rising and fluctuating in the Midwest, I have been getting away with a 350 GDD instead of the 280 GDD I used in fall. Now, everything I just talked about was for perennial rye, so you will have to determine the growing temp range for your own grass type. This is working for me now based on grass I’m colleting when mowing. Good luck!
Thank you so much for this!
You are most welcome. Hope it helps! Cheers!
This was helpful, Thanks for posting.
Glad it was helpful!
One Question. In row 27, because you have a negative, you lost a couple GGD's. Is that correct? All other calculators I've seen treat a negative as a "0" instead of subtracting GGD's. Probably not a big deal but just curious.
That is correct, anything in the negative I zero out that GDD. Basically I just move the previous positive GDD down so it does not mess with the formula. Now, even if the GDD is 0.1 it’s positive so I still keep it. Have a great growing season! I’m dealing with some ridiculous tnex rebound right now with the warmer than normal temps this month.
Im going to go 1/2 rate every 2 weeks to keep it simple. Its Bermuda, it wont die
That sounds about right for summer. In my area as the weather gets colder I can stretch that out to every 4 weeks. Going to try Monaco Bermuda spring 2025! Cheers!
@@MidwestLawnGoals-in2gv good luck!!!! I just seeded 11,500 sq ft of Monaco 13 weeks ago, had my very very best seeding when I pre germinated until I saw many roots shoot then mixed with humichar, I seeded 3 different times, thunderstorms lol the longer I kept the seeds wet the better. This grass is dark green lol
@@kkevinj1 Can't wait to test it out. I will post my process for comedic value. Cheers!
@@MidwestLawnGoals-in2gv lol Ul do fine
What website shows us when to apply PGR?
I believe the most popular one is greencastonline.com. It will give you the GDD but you still have to add it up yourself based on when you applied it. If you have questions on how I did my tracking contact me through my email and I can do a 1 on 1 walkthrough with you. Cheers!
Play 1.5x to 2x speed
Yeah, I need to speed things up, lol
Why "-0"?
I live in North Carolina. Going by ACC GDD, I would have to apply every week (approximately). This appears to be PGR OVERKILL. Are you sure this method is accurate?
Thanks.
