Question for the group is - What is the general rule of thumb on applying plant growth regulator in the winter months to perennial rye overseeds? It's growing fast and I'm not really feeding it. I sprayed my bermuda the day before I seeded with 0.25oz/k to stunt it a little and give the PRG time to light off.

GreenKeeper has my current app on the bermuda at 194/255 GDD for what that's worth.

Any feedback is appreciated.
Great question that I'll be following. Down here in Texas PRG grows insanely fast all winter long. It never gets cold enough for it to shut down.

For those like me who were worried their PRG wouldn't be thick enough, just give it time. This Friday will be 4 weeks since seed down and this last week it has changed completely. I just needed patience.

Question:

I'm planning on over-seeding next week with some Champion GQ PRG(Provided that temps are okay). My question is ? Do you think it would be too much stress on the lawn to level a little bit after the grass has grown in? I was thinking about taking advantage of the cooler temps and doing a little leveling.

Thank You for any insight !!
I did some spot leveling and then seeded. Prg is coming up good on sand. These were areas that a groundhog came in and then it rained and washed up some tunnel holes, so I filled them in with sand and seeded over it. It seemed to work well, I wish I would have done a little more.

What's your HOC? I scalped my bermuda to .375 and have been keeping the PRG at .675 and im seeing a lot of bermuda starting to reach the same height as the PRG now. It's been 15 days since seeding. Wondering if the PRG will tolerate a scalp or will I be ok?

@mha2345 HOC is 5/8”. Did you spray PGR before the scalp? I sprayed a double rate on mine the day before I scalped and no Bermuda has grown up to the ryegrass height.

For the Phoenix-area folks, where are you buying your seed? Have about 10k sqft to tackle immediately after Halloween. Thanks!

I was reading an article and apparently Augusta guys are already expecting a lack luster turf compared to normal

That's awesome! Great job. Understatement to say the weather has been perfect?

I didn’t apply PGR :(. I read through @Ware thread and saw he cut at .5” due to this issue, so I may try that and bump back up.

Nice!

That's the issue when you plant too soon. You are basically trying to time when Bermuda goes dormant.

IMO, a lot of guys on here went fairly early. In PA, and NJ I was planting seed in September. I planted on 9/26 up here in Charlotte and am finding that was even early up here this year. I hit the tiftuff with PGR a couple days before as well and started with an HOC of 0.75. In 20 days we have had 312 GDD only 1 day with GDD < 10. I was mowing daily until the seed started germinating and cresting above the tiftuf. We have had days of rain and my rye is now 4 inches in some spots.

Anyway. Established cool season grasses tolerate short haircuts fairly well. However, I'd take it all down 0.5 then to 0.375 after a watering then let it grow back to desired height.

I'm going to warn you, this stuff grows way faster when the temps drop to the low 50's overnight. Mine grew all winter long up here last year. I had a 4 or 5 days of rain and had to go to a rotary mower it got so long. Stayed at 2.5" the rest of the year and still have the nicest lawn in the neighborhood.

It takes 2x the PGR as Bermuda to tame this stuff. 200GDD reapply rates and that's using a base of 0 C (that's right freezing)

I’m sure this has been answered somewhere else, but how often and how much do y’all water once the PRG has established itself?

How long does it take rye to stand back up if it got laid over while mowing?

First cut today. Spread 8-1-8 XGRN and mixed up some micronutrients, humic, and kelp and sprayed. Going to water it in later on.

Not long but can’t say definite time. If your notice it’s laying over and not standing back up then usually that’s a sign it needs more water
