Pics would be helpful.

Here you go.

That's not bermuda. I had the same thing come up in an area where I seeded bermuda this summer. I don't know exactly what it is. Your only options right now is to pull it all, or keep mowing the bermuda short. I pulled some of mine, the rest I am mowing off 2 to 3 times a week. Next season after the Bermuda is established, you can use a selective herbicide to take care of it.

What type of seed did you use? I am not positive, but I do not think that is Bermuda. When I planted my Bermuda seed, it did not mature into a large plant that quickly. It was more like hair stems by this time. In the far background of the 2nd pic, that is possibly Bermuda, but hard to tell. Where are you located? I am in the DFW area of Texas, and in May, I do not think the ground temps. where ideal for Bermuda seed to sprout.

I could be wrong, but what you are looking seems to be some type of weed.

Yes pics were helpful. That's defs a weed. Where do you live? Why is the soil green and the grass so thin? Is this area getting a lot of shade? If so then no amount of aerating or seeding will make the shade go away. Can you post a picture taken from a distance?

I used common Bermuda seed. That particular patch of soil has some fungus problem that I am trying to deal with. Thankfully it is isolated. And yes that patch is in a bit shady area (right next to the house). The rest of the lawn is in full sun. I will try and post some more pics tomorrow. Thanks all!

Here are a couple more pics. I am in the Charlotte NC area. After looking at the grass more closely it may be crabgrass. I did not put down a pre-emergent this season because I was afraid it would keep the Bermuda seed from germinating. I have been reading up as much as possible (this site has been especially great) to learn what I need to do to get my lawn in shape. I had determined this seaso would be the one where things would come together. Any help is appreciated.

I don't even see any bermuda in the closeup pic. Did any of it sprout? If so, continue watering and start mowing low when appropriate. If none sprouted, you can spray the entire area with roundup and reseed. It's not too late to do that.

Did you scalp the area before you planted, or was it bare dirt? I am not familiar with your area, but what have the temps and rain been like when you seeded? In Texas prime time to seed Bermuda would have been this month, especially with the rainy May we had down here. I would figure that your area did not reach ideal ground temps for Bermuda to sprout in May.

I was curious, so I looked up your temps and possibly if you planted at the end of May you have had some success with the seed germinating, but hard to tell from the pics. If it has been a month, it should be ok to cut and then re-examine what you have a little closer. If you see none or very little Bermuda, maybe do as blackdirt suggest or you could scalp and then re-seed. Round-up may work better if in fact all that is weeds. You still have plenty of time to get most Bermuda established before winter. Just my 2 cents.

I cut it down to about 1 1/2" before seeding. The temps are more ideal now for seed germination (90's during the day and 70's at night). I have kept the soil damp. Reseeding is not an option. If it doesn't work out this season I will probably just try again next season. Will putting down a pre-emergent prevent Bermuda grass seed from germinating?

I wouldn't use a preemerge before seeding.

That's what I thought and that's why I held off on the preemerge this season. Once I planted, I started off watering every 6 hours for 20 minutes each time. Did that for about 3 weeks till I started seeing some seedlings. I admit, though that the temps were still a little cooler back then. I have since cut back to every 12 hours for 30 minutes each. Does this sound about right? I thought about going back to the former watering schedule since the temps are so much hotter now. What do you think?

Also, I have some hoses that I need to trench and bury before I start cutting lower but I plan to start cutting down to about 2" ASAP. I tried to do this with the hoses above ground and tore one up. I read somewhere that this will starve the rest of the grasses for lack of photosynthesis while the Bermuda will thrive (being a creeper). Any other advice is appreciated as I am really making an effort to get the lawn established this season.

Thanks again for everything!

OK, I'll mow as low as possible. Do you think that going back to the more frequent but shorter watering just for a week or two is a good idea (I was thinking to take advantage of the hotter temps and maybe get some more of the seed to sprout).

Not sure how much water your sprinkler puts out, but every 6 hours for 20 min. sounds like too much. I watered for about 3-5 min. 4 times a day while the sun was out. I have a sprinkler system installed, this may vary with hose attached sprinklers, but shouldn't need 20 min. The results you are after is keeping the soil moist, not saturated. This may be why the fungus showed up in your first 2 pics. Of course that is an after thought now but you can consider if you need to re-seed next season. For now, since you are a month in and about to mow, you should be able to cut back to possibly ever other day or every 3rd day. You want to eventually get to 1" per week when the temps are 90+.

If you haven't found the Bermuda Bible, google it and it will help you once you have grass that you are trying to maintain. With the heat and infrequent watering, you will start to see less weeds and more Bermuda as it spreads. Bermuda spreads very fast when properly maintained with fertilization and proper watering techniques.

Remember Bermuda is hard to kill. Once established it goes dormant to protect itself.

OK cool. I will keep things as they are for now and probably try 30 minutes every morning later on. I'll keep an eye on the soil to see if it becomes too dry or saturated. I read that once the grass is growing you should water less frequently but more deeply to establish deep roots.

If it's been a month or more since you seeded, all the seed that was going to sprout has sprouted. At this point I would turn my focus to the grass that did sprout and water it accordingly.

Chiming in from up near Raleigh, NC, where I did something similar at about the same time as you (seeded my entire front yard with Bermuda on May 23) and a bunch -- I mean, a BUNCH -- of those exact same weeds popped up on me.

In spots I got some very good Bermuda growth while in others there's definitely some Bermuda growing but those weeds are threatening to overrun it. I'm determined to either crowd them out, or wait them out, but I'm keeping an interested eye on this thread for any other ideas on getting rid of those weeds.

Can you post some pics to compare?

Sure -- the first pic here is what those weeds of yours will probably grow into. I mowed yesterday (my third mowing) at a height of about 1.25" and this is what those weeds look like after that mowing. Very leafy and soft, looks like a rather disgusting salad. If you look closely you'll see blades of Bermuda in the middle of those weeds. Hoping that bit of Bermuda survives and gets strong enough somehow to crowd out the weeds.

My second pic is one of the good spots where the Bermuda came in very strong with little or no weeds. I planted that spot exactly 4 weeks ago today.

That's some nice coverage. My lawn looks like the top pic. I have pretty much lost hope for a Bermuda lawn this season.

deeciple, how are you watering it now? How often and for how long?

Did you have bermuda to begin with and you just seeded more in because it was thin?

Is there some bermuda in among the crabgrass?

That really looks like crabgrass. Nothing can compete with crabgrass in the summer heat, but you might be able to take it out once the bermuda is established. You'd need something like Celcius (expensive for a lifetime supply). Or you might be able to nurture the bermuda in the fall, but those two grasses really have similar requirements.

The best control for crabgrass is to develop a really dense stand of grass along with infrequent watering and preemergent. Getting the dense grass is your current hard part. Infrequent watering means monthly in the winter, every 3 weeks with temps in the 70s, every 2 weeks with temps in the 80s, and every week with temps in the 90s. Crabgrass seed needs continual moisture for about a week to germinate. By allowing the soil surface to dry completely before watering again, you break the crabgrass life cycle and give the bermuda a chance to thrive and fill in. Growing bermuda in hot climates is still a lot of work with 2x per week mowing and monthly fertilizer, but it makes a great turf.

I am definitely watering too much then. Every 12 hours for 30 minutes. I will cut back to every 7 days. How long to water for? I know Bermuda is drought resistant but will it be able to handle that stress?

I had a mixture of Bermuda and fescue to begin with. I was hoping to eradicate the fescue this season but then I got this broadleaf junk (well at least the fescue is gone lol). There is Bermuda mixed in the crabgrass because I can see it if I pull the crabgrass back with my hand. This Monday I hope to dig trenches for the hoses I have running to my sprinklers and then I will start mowing really low. I have purchase some Scotts Southern Lawn Food (very high in nitrogen) which I will feed into the lawn after the next cutting (it will be about 1 1/2 months by then).

Bury hoses for a sprinkler? Why not use PVC pipe like everyone else? There is a general problem with using rubbery hoses instead of solid materials. Hoses expand circumferentially ever so slightly due to the pressure of the water. That expansion saps pressure away from your system. That means your sprinklers will not shoot water as far. Solid pipe also expands but much (MUCH) less than hoses. That expansion is called capacitance just like in electrical circuitry. Ideally you would use solid pipe above ground to water with your sprinklers, but it's much more practical to use a flexible hose. Undergound it is best to use something more solid.

When you bury the pipe, be sure all the soil that comes out of the trench goes back into the trench even if it mounds up above the level of the rest of the lawn. When the soil settles it will all be level again. That can take 3 years. if you don't mound it up then the soil will settle showing you exactly where you buried the pipe.

Silly question... Where can I get the fittings to go from the PCV pipe to the sprinklers. How are these attached to the pipes. I have never done or even thought of doing it this way.

Lowe's. Home Depot. Take in the parts you have and find a clerk. You might have to push the button to get help. They can tell you what parts are missing.

Did some more research. It looks like our mystery weed may be Japanese Stiltgrass.

Interesting reading, deeciple. I did have an encouraging development the other day. I've been determined to maintain my Bermuda at 1.25" and Sunday marked my fourth mowing. After that mowing I noticed much of the CG was starting to turn yellow while the young Bermuda is looking healthy.

We've been in the middle of an intense heat wave here in NC (temps in the mid-90s/low 100s for 9-10 straight days now). I gave the lawn a deep inch of water early this morning and mowing #5 is scheduled for tomorrow. Here's hoping the yellowing continues.

Joedy McCreary, I remember the heat wave. I am in Charlotte and we had it down here too. Happy to hear that your CG may be dying off. My Bermuda is starting to thicken up a bit too but my CG is putting up a fight. After my next mowing and feeding I am hoping the Bermuda will spread more and dominate.

I have exactly the same crap in my front yard along the sidewalk. It's the first year I haven't put down any preemergent and the stuff is threatening to take over the area. If it's really crabgrass then I don't see any way this is going to die off on it's own without some "help". Mine has yellowed a bit too but it's still growing like crazy. Within a day after I mow, it has shot up above any of my Bermuda grass and could use another cut.

I've hit it twice with Drive over the past month or so and some areas of it have browned. The roots apparently have not gotten the memo because it's all still thriving. I hate to hit it again in this Texas heat but plan to do it. I'm pulling what I can in the meantime. Nasty stuff.

I have the same thing going on. I killed and rototilled the entire backyard, starter fertilizer and Dune bermuda seeded. The crabgrass emerged beautifully and even. Some bermuda was noticed withing the dense crabgrass areas. Now I have a ugly yard of crabgrass with few bermuda grass blades peaking through in areas. I started to dehydrate the soil for 5 days and then rehydrate while mowing 2 times per week but the crabgrass grows so fast.

How are your yards now 5 and 6 years later. What worked for you?
