I sodded 18 pallets of Palisades a couple of weeks ago. Got a stray weed here and there coming up. Some are right in the middle of the square which makes me think it was something from the sod farm and not coming up from beneath. It's not a lot and not a huge deal. I've been pulling them by hand as I see them. I scraped the yard pretty good and applied some Ranger Pro a couple of weeks before sodding.

Should I apply anything yet to knock the weeds down. Sod is doing fine but not quite filling in just yet. How long will it take for the grass to really start filling in to choke out the weeds?

From a little bit of Google searching, it's suggested that you wait a full growing season (3-6 months) after laying sod down. Might be better off pulling the few weeds you see.

Sounds like you really need to let the sod settle in before you decide to put anything down on it, so that's understandable. 3-6 months does seem like a long time though.

That's mostly what I have read also. The company that laid the sod said to wait until July to even cut it (or until it reaches 3" tall).

I also have a pipe fence around the property. The neighbors yard is weeds. He let me spray a line of remedy and diesel along the fence line to prevent weeds from seeping into my yard, but I imagine seeds will get blown in. Is that a good defense to keep the weeds from spreading to my yard, or is there something else I should do?

I had 5 pallets of Empire Zoysia installed in February and the weeds were coming in pretty bad between the pieces but now that it's pretty well rooted most of the weeds are getting choked out. My contractor came and applied some weed control in April but not very much. I'd pull up what you can see and give the sod more time to get settled in before doing anything drastic. Ronk and CrawDude are the experts though.

Burn your neighbors house down.

But seriously, keep a 12" right of way between his yard and his and you should be good until later this year.

Once it is rooted down, it's actively growing, and you've mowed twice you can spot treat weeds. That being said the more chemical you keep off your grass the better. If you can hand pull them do it.

Consider yourself lucky. I have a friend with a neighbor that will lose his mind if he so much as trims an inch into his weeds. He even put up a little garden flag facing his property saying "the weeds are for the bees" and he has string along the property line. But it's only like a 5ft strip between the properties. The rest of his yard is lawn. Weirdo

I've been pretty fortunate with neighbors in my lifetime. If he wouldn't have let me spray a line of weed killer down his line, I would have done it on my side. I'm on 2.5 acres so it's not economically practical to maintain the whole property. Most people in my area just keep their yards as they are.

Think I'd be replacing my well every 2 or 3 years if I tried to water the whole property. I just sodded the pool section of my yard. I have about a 1 acre pasture, and my front yard is 1 acre. The pool yard is about half an acre and I sodded 8,100 of that. Still need about 3 more pallets to finish off the area that I want sodded in the end. Only 18 pallets fit on a truck so that's what I got.

My main 2 problem weeds when first installing sod were Virginia buttonweed and nutsedge.

Virginia Buttonweed will choke out your Zoysia if you don’t keep it at bay. Good thing is it’s really easy to identify and pull when it’s young. Just walk your lawn every few days with a grocery bag and hand pull. I think it prefers a lot of water so look for the low/wet spots.

Nutsedge I didn’t care about initially, it just looked goofy for a few months until I was comfortable spraying Image for Nutsedge and now SedgeHammer.

I hand pulled and bought one of those weed pullers you stick in and twist. Drink a beer and spend an hour a day every few days and just pull.

I put down some Zoysia last spring and had to pull tall weeds all summer. Now onto the second year and I don't see any weeds at all and the Zoysia has completely taken over.

THREAD HIJACK - what would you recommend spraying for weed control on newly laid Bermuda (Tifway419)? Laying 20 pallets as we speak.

Thanks fellas!

Nothing, not even a pre emergent. Just water it a ton and try to stay off of it for the first few weeks.

Walk your lawn every few days and monitor for weeds. Hand pull them when they’re young before they become mature. I wouldn’t spray herbicide for the first 3 months.

More info than you asked for, but your sod should come full of nutrients from the farm so you shouldn’t even need fert yet. Since you have Bermuda, you can fert more often than other grasses. I’d wait 4 weeks to mow and you can put down a fert high in Phosphorus which will help establish root growth.

If you want to get fancy, N-Ext makes some more advanced products and they have a root growth stimulant. I think it’s Sea Kelp, Humic Acid, and Fulvic Acid mix. You can apply this now. You don’t need it though.

Thanks for all of this info.

I was going to put down a 12-12-12 starter fertilizer once it's all laid and before I start watering. Ronk told me that it's probably not needed, but wouldn't hurt.

Funny you mention the RGS - I was considering grabbing some of the 0-0-1 RGS Root Growth Bio-Stimulant, Sea Kelp | N-Ext and spraying that maybe next week.

I was also considering doing a good 24-0-6 at around week 4 after the first cut. I assume I should cut at the 1" mark?

Thanks for all your help. It is much appreciated.

If your lawn is level you can cut at .25. If you want a next level lawn get a real mower, carbon g, and t-nex.

If the sod looks good (as it should), you might just be wasting your money on fert.

You could use a 12-12-12 the first few months, then back off of the phosphorus or you’ll build up thatch quickly over time. This is how I remember the macronutrients:
Nitrogen = Green leaf growth
Phosphorus = Root establishment
Potassium = Health

Whenever I scalp every year, I always apply something high in Potassium. Otherwise, a high N and low P&K is what I do.

Gotcha. Yes, the 419 looks great already.

I was just going to do an initial 12-12-12 one time now along with the RGS...water, water, water. Cut at the 4 week mark then apply the 24-0-6 and water in.

Go for it man, you won’t hurt it. Bermuda loves nitrogen, just be prepared to fork out some money on fert.

Check your local box stores around September/October for deals. They’re trying to get rid of their inventory for the winter, so I stock up in the fall for the following year.

1) Hand pick is always best option
2) Spot spray weeds is a good alternative if needed

I would avoid broadcasting any weed killing/prevent products with turf grasses as they can prevent or slow the thickening/filling in.

Yep - my plan was to spot spray only; was just looking for some insight on a good product since this is my first (and brand new) Bermuda lawn.

Appreciate all the info!
