When to apply post emergent after seeding Bermuda?
Posted on 6/27/24 at 12:23 pm

Greetings all. I've been a 20+ year lurker, first time poster.
I've been following many of the posts about seeding Bermuda. Like most, my yard was a disaster after the drought last summer. I bought some Hancock Royal TXD for the backyard and put that down April 13th to overtake the mix of Centipede and St. Aug. It's filling in great however so are the weeds now and surprisingly, the Centipede seems to be doing great again also. I've read to wait until things are well established before applying post emergent. I've got Celsius, Sedgehammer and a surfactant I've used in the past to control the weeds. Would you think I'm at that point now based on the pics below? Really itching to clear out the weeds but I don't want to harm the new Bermuda.
Appreciate the feedback!
Where it started - April 6
After leveling & seeding - April 13
Where we are - June 21

Well done
Your best allies will continue to be frequent low mowing, fert, and water.
I personally would be willing to apply low rates of celsius and sedgehammer (combine them), but without using the surfactant.
If this does not acheive desired results after 3 weeks, do it again. Then leave it alone. By that point you'll just want to start thinking about a fall pre emergent.
Additionally, Centipede hates phosphorus so give it a good 20-20-20 on your next round of fert. The bermuda won't care.

Let it fill in and hand pull the weeds.

Can't do much with sedges or kylinga though, which will only spread if pulled.

Thanks for the info. I've been mowing every 2-3 days, along with fertilizer and watering.
The VBW isn't bad to pull but some of the other stuff is getting out of control I can't keep up with pulling it by hand.
I have Prodiamine that I plan to put down come fall.

Yea rotary mower for now. I'm at the second to lowest setting which is about 1.25"-1.5" cut.
I'll probably look to get the Earthwise 7 blade reel mower at some point that I've seen mentioned on here.

I have a 7 blade and it is awesome.

Is it not too early? His grass is only a couple months old. I planted in the same time frame and have been advised not spray anything. Just fertilize and mow low and frequent.
To the OP

Get you one of these and do little by little. Something is very satisfying about it.

That looks great, I am going to seed my disaster of a lawn and the other areas with no grass next year for sure.

Can you seed in late September early October?

You won’t be able to use a pre emergent so you’ll be playing catch up in the spring with winter weeds. That’s assuming a best case scenario that you are actually able to grow a stand of grass with dropping temps and sun angles.
This fall, focus on dirt work/leveling to prepare for seeding around April or May.

Thanks for the feedback. I have used pre emergent for years but my yard is always full of weeds. I don't have confidence in those products. I guess I was thinking that if I seeded in spring and fall that bermuda would choke out the weeds.

You’re correct in thinking that the best weed preventer is a thick stand of grass.
Have you already seeded this spring?
Am I understanding correctly?

Yes, I overseeded with bermuda in May. I am currently trying to follow advice of the board to fertilize monthly, mow often, and water regularly to promote bermuda growth. I was thinking I could overseed in spring and fall instead of pre-emergent applications.
When should I stop applying monthly fertilizer? I'm assuming Oct?

As a rule, there is no need to overseed Bermuda. Is it thin or something?

Sorry I'm overseeding centipede with bermuda. Trying to get the bermuda to take over.
Posted on 6/29/24 at 4:11 pm to armytiger96
Can you just overseed the centipede with Bermuda, fert with nitrogen, and cut low? Is that the process for trying to get it to take over?
