I would really like to know what the active ingredient is in the products you have used and are planning to use. I'm assuming it was a liquid product. There's one herbicide that is very tricky to use and should only be used once to the exclusion of all others.

I assume you mean Weed n FEED, not seed. Weed n Feed products usually don't feed or weed very well. There are reasons for that. We tell people if they need fertilizer (which you do not at this time of year) then use fertilizer. If you need herbicide (which you likely do at this time of year), then use a spot spray type liquid. Some herbicides will wipe out everything, so again, really need to know what you've used and what you have in stock. I would return the Weed n Feed, get my money back, and plan to fertilize in another month or so.

Here's a picture of the seed heads and flowers on buffalo grass. Is that what you see in your grass?

Where are you? Central Texas covers a lot of ground.

I am in Schertz, TX. Yes, I did mean weed and feed, sorry I had to write that post twice and did it in a rush. I used Weed-B-Gon for Northern and Southern Lawns, active ingredients are as follows:

2.127% MCPA
8.658% 2,4-D
0.371% Dicamba

Although the grass in the picture looks very much like mine, I do not have any of the brown stuff (seed heads?) at the top. I do not know how to identify weeds very well, but it seems like dandelion is my main problem, but I have a LOT of spots of what looks like the beginning of dandelion with no flower coming out. It looks just like this without the flowers. I must be misinterpreting something then, I thought now was the time I needed to get the fertilizer out, before it starts hitting 90+ every day? I have heard it can burn the lawn if you put it out while it's too hot.

Okay I'm in San Antonio and moving to Bandera. Hold off on the fertilizer unless you want to use an organic like alfalfa pellets or corn meal.

If you've never seen those flowers then you don't have buffalo. Can you take a picture on a cloudy day from a height of about 3 inches. If the grass has flowers or tassels or anything on it, that would help.

You have not used the really hard stuff, but then you did use 7x too much, so I'd let things rest for a couple weeks. Today's herbicides often don't show progress for at least a week. If you have St Augustine, for example, 2,4-D will kill it. Applying anything at 7x the rate would probably wipe out St Aug. St Aug is a very hardy grass, but one weakness is sensitivity to most herbicides. It's weird.

Let's figure out what grass you have before going crazy with treating it. If you water the fertilizer in immediately after applying, it should not hurt a normal grass. The problem comes if you don't water it and then the morning dew creates a very salty solution that will kill most grass (but not usually St Augustine - weird). If you have a hand sprayer of Weed b Gon, you could spray those dandelion looking weeds. Just spray the leaves - don't drench the soil. They might be thistle, which looks very similar before it flowers. As for fertilizing the lawn, I'd just enjoy the bluebonnets for a couple more weeks.

Sorry it took so long, but here are the photos. I hope the quality is good enough, if not I'll take more. Still none of those flowers or anything, but it was mowed not long ago. Most of the dead stuff is just clippings, it's starting to look a little better actually.

Blurry, as you know, but you have the right idea. Tap the focus next time.

You might have hybrid bermuda or zoysia. For the next month everything is going to look better on a daily basis.
