Growth regulators and over seeding.

Post by turf_toes » August 23rd, 2014, 8:14 am

Along with my backyard renovation, I have overseeded the lawn on the north side of my house with Bewitched KBG.

The lawn there is pretty thick still. So I wasn't sure this was going to work. But two weeks into the project, I'm seeing lots of new grass seedlings.

Here's what I did.

1) applied a growth regulator to the overseed area. Then I waited four days.

2) I scalped the overseed area down to 1.25-inches. Scalp probably isn't the right word though. Blueberry is a great grass for handling the stress of sudden changes in cutting height. It lost a lot of color when I lowered the mowing deck. But it still looked decent. I waited two weeks.

3) I reapplied the growth regulator at the higher dosage level. I waited one day.

4) I overseeded.

I've been cutting the grass once per week with a reel mower. It's been great so far.

I wanted to throw this out there as an option for anyone who wants to give their new grass a better chance of getting established in an existing lawn.

I sure hope your project works out and you have good results with the overseeding into existing grass stand. Maybe the addition of the PGR will show that it h as been the missing element. Which PGR product did your choose?

I have had some thoughts on trying it with a few additional steps. I have considered putting down some compost (1/4") to create a better seed bed. Then blow some peat moss over it and add some very fine soil moist to that to create a moisture retention blanket. Any thoughts on the additional steps?

Just like the Reno. Five times a day.

That might work. I've just never been a big top dressing fan. I've always gotten best results just rolling the seed into the seedbed, then watering.

I think top dressing is critical when in ground irrigation isn't available. But for my recent projects (all renovations until this one), I have gotten great results without it.

I've used embark and generic primo on overseed. Generic primo worked great for me.

Embark on the other hand was very harsh and I had damage to the existing turf to the point that it turned into a renovation.

Never rule out human error but my embark days are done after using primo.

Yeah. Sorry. I forgot to answer that question. I'm using generic Primo Maxx.

The process you're using us very typical of an overseed situation on high maintenance warm season turf. A lot of turf managers have figured out that regulating and then scalping is the way to go. The existing turf is usually on the road to recovery by the time the rebound from the Primo kicks in and by that time seedlings are up and growing. The real key is timing. With goid documentation and observation, you'll get a little better each time. Nice work.

Just wondering how you got turned on to Embark? That is a very limited use PGR that is primarily used to inhibit seedhead production on golf turf during the spring months. Get it on high cut turf, especially KBG and you'll kick the crap out of it for 8-10 weeks.

Did you keep it cut at the 1.25" for the two weeks also or let it grow out?

I have to get some generic Prino Maxx for the future. I have Embark. Bought it a couple years back because it was cheap. I sprayed a strip of TTTF, KBG and PRG next to my back renovation and over seeded with KBG. That was August 1st. Seedlings are already higher than the established turf. In fact I'm wondering if the established turf will ever start growing again!
TT's methods are right on though. I think the only way to get good results over seeding KBG with KBG is to use a plant growth regulator. Now where can I get some generic Primo in case I want to do this again in the future?

In your neck of the woods, check with Atlantic Golf and Turf.

Any experiences with paclobutrazol on KBG?

I'm cutting once per week with a Scott's reel mower back to 1.25-inches.

Why did you overseed the blueberry on the north side?

Because it is the north side of the house.

It tends to get less sun there.

Since I was already doing a Bewitched mono stand renovation, which as you know has great shade scores, I thought 'why not try to overseed it into that section of lawn?'

It was a couple years back. It was cheap and I think it was mentioned on here. I don't remember a generic primo at a reasonable price at the time.

I see Embark mentioned still in the renovation section still, so this thread can serve as a warning.
