if you had kbg and especially a spring seeding, I'd be doing several applications of Tenacity. Not sure if Tenacity would take care of that but there is a good chance it would along with dozens of other weeds.

Probably doesn't much matter what it is other than a broadleaf weed. Sounds like you didn't prepare the soil correctly. You are supposed to water the bare soil before seeding and give it about a week. When the weeds sprout you spray them with round up and then, do this again if you have time. That way when you put down the seed you will have much less of this to deal with.

Not convinced it is a broadleaved weed. With the leaves/blades lacking any petiole and wrapping around the stem, that is more the characteristic of a monocot or grass-like plant than it is of a broadeaved one (dicot).

The only reason it makes any difference is the type of herbicide needed to control. Unless you opt for a broad spectrum type like RoundUp that kills anything, weed killers are typically directed at one or the other.

Greetings, Sorry but everyone here is confusing me. Are you saying mix the seeds in with a starter fertizler then spread? I looked up Milorganite and it says that it is an organic fertilizer. Don't I need a turf crawling with microbes and living organisms to use an organic fertilizer? If so then I would have to put around two yards of compost on my lawn first so I have microbes that break down the proteins in organic fertilizer which in turn releases the nitrogen, no? Wouldn't any Starter fertilzer high in Phos and Nitr also work? Can anyone answer my other question about the seeding rate for my particular Mix? Is it 2lbs per 1,000 sq feet or 3lbs or 4lbs? Shoud i use all 6 lbs for 2,200 sq feet or use 5 and save a lb for overseeding any spots that don't germinate so well- Thanks, Dan

Bahiagrass is something we curse, causing our lawn to look unmowed after just days. The seed stalks get a foot tall in that short time, covered with black seeds that stick to legs, feet. If not for bahiagrass, we would only need to mow about every 3-4 weeks. We don't care what kind of grasses or other soft plants grow in our mowed areas, there's tons of Tradescantia (spiderwort,) dandelions, bulb Oxalis, but I dig out the bahia when I can, at least where we walk a lot. No, it doesn't spread quickly by rhizome, but by seed, it can take over a lawn in just a few years because nobody wants to mow that often. You don't need to do anything to the ground to get the seeds to sprout. Here's a pic of bahia in other, regular grass.

It is unfortunate that misinformation continues to be repeated about glyphosate. Denmark has not banned glyphosate, nor have "many European countries". Denmark at one point thought that some of the monitoring they were doing showed that glyphosate could move into agricultural field drainage water in autumn but once they looked at their data and related it to the methodology they used, they enacted no ban whatsoever. As the Danish Environmental Protection Agency specifically stated: http://www.egeis.org/home/main/Evaluation-GlyphosateDEPA.PDF "Against this background, the Danish Environmental Protection Agency believes that no unacceptable risk of pollution of the groundwater is associated with the currently approved agricultural use of glyphosate. The Agency thus does not consider that the updated state of our knowledge provides any technical grounds for the imposition of restrictions on the autumn application of glyphosate." Used properly, glyphosate will not pollute drinking water nor will it have adverse effects on humans. Once applied, it binds tightly to soil particles and is not herbicidally active. If it is applied to hard surfaces such as sidewalks it can move offsite of course. It can also move if there is active soil erosion carrying soil off site. It is of very low toxicity, and breaks down completely into natural constituents over time. It is of equal or lower toxicity than most household products such as detergent, soaps, shampoos, cleaners etc. and far less toxic than some of the "alternatives" often discussed such as bleach, kerosene, high strength vinegars and so on. There is so much misinformation being repeated on the web that it is difficult to get reliable information. This link provides an published overview of the available literature.

You should be doing the first mow shortly and the second one a week after. If you didn't apply fertilizer at seeding you need to do so, they need to develop properly to survive summer. By day 60 after germination you should have mowed 4-5 times. Use a pre-emergent as described here in spring (since it's perennial, this will not affect already established goosegrass, see below for post control): http://lawniac.com/conquering-crabgrass-and-annual-weeds Use the method described here for post-emergent control( yes, I know it says Bermuda, same combo is used for goosegrass): http://lawniac.com/eliminating-bermuda-from-your-lawn Multiple treatments may be needed to achieve control. Avoid spraying fluazifop in hot weather, it will wipe out the fescue as well.

True, maybe not broadleaf. I jumped the gun, assuming the photo showed a plant larger than grass that had leaves ready to open. There's no scale to the image, like a quarter. A photo of the lawn might answer the question. It's hard to say what to do about it without seeing anything. If there are individual shoots here and there I'd leave them be and let the KBG grow undisturbed. If it is a carpet of weeds that might require some action.

What state are you in? I assume it is northern since you seeded KBG. In most areas of the country this is the wrong time to seed a lawn. Unless you are in Canada or PNW it is likely that the new lawn will die out in July. If that happens then you will have an opportunity to prep the soil properly before reseeding. Is it a large area?

Did you use straw or anything like that to cover the seed?

May be one of the nutsedges-invasive sedge grasses that are a little tricky to get rid of. If it’s nutsedge, best waiting til spring and when the leaves are young, using nutsedge killer. Sometimes need multiple applications, but you can eventually get rid of it. Don’t try pulling it up-the “nut” is usually down fairly deep and you just snap off the top.
