wasted money on crabgrass preventer from Lowes

Interesting, late Jan should have been early enough but we had a warm winter and crabgrass seeds germinate at soil temps of 55 F. Dimension (dithiopyr) is an effective crabgrass pre-emergent with the added benefit will kill young crabgrass up to the 3 leaf/tillering stage. I had a significant crabgrass issue in my lawn, no longer. Try using Dimension next year.

If you have a centipede lawn you can kill the crabgrass with sethoxydim.

I don't understand the big deal about getting rid of crabgrass. I had a lot of it in my back yard a couple years ago and I went and pulled it all up in an afternoon. Never came back after that.

I used that same kind last season and it worked great. So good that I didn't even use it this year and yard still looks good. Granted, I didn't have a real bad crabgrass problem to begin with.

Man that never was going to work. Your application has to be precise especially with pounds on the ground.

Get to spraying chemicals and your crabgrass with be a thing of the past.

Pre emergent at least twice a year rotating between prodiamine and gallery.

Post emergent MSM turf with atrazine

Craw, is crabgrass up already in south louisiana? I am in Dallas so I don't know if it has germinated down there yet. I know it was a warm winter but for people to have crabgrass before the end of March is early. We don't worry about that in north texas until the end of May. I am wondering if some of these clumps of crabgrass are actually dallis grass.

ronk good question - I’m not seeing in my yard or neighbors in Baton Rouge, though I use pre-emergent, but I know some of my neighbors do not. However, some posters reporting this are from New Orleans area and you’d surprised at the difference in temps between New Orleans and Baton Rouge. But I will say this from my own personal experience with my lawn prior to using pre-emergents, crabgrass wasn’t that noticeable this early in the year.

But I’m like you, I’m now thinking some posters are generically calling any grassy looking weeds they are now seeing in the lawn “crabgrass” when it could be a perennial grassy weeds like Dallisgrass that is now greening up. Probably would be best to suggest posters post photos of “crabgrass”.

Like the OP who stated he applied Crabgrass Preventer from Lowe’s in late Jan and it didn’t work - it was unusually warm this winter - but I’m now questioning if it’s really crabgrass he is seeing and not something else. Seems to me late Jan application should have been early enough, even further south than BR.

OP if you are still following why don’t you post a closeup photo of your “crabgrass” so posters can try to ID it so see if you you are really dealing with crabgrass or perhaps another perennial grassy weed.

I usually have large patches come up around my muscadine vines in the back due to the fertilizer and that hasn't shown itself yet. Either the barricade worked well or it's not up yet. I did nothing to control it last year outside of an early dose of Sethoxydim.

Dallis grass is growing nicely though

Dallis grass is some tough shite.

That and annua poa. I've learned more in the last 2 years about weeds than in all my 40 plus years of life. Talk about information saturation.

But it's what it takes.

This shite is growing well whatever it is

I have used the same stuff for about a year and it has done decent on crabgrass and woodsorrel, and excellent on henbit but does absolutely nothing on chickweed or poa, it actually seems to fertilize and encourage chickweed and poa.
