Light green grassy weed
Comments (12)I'm currently battling a very similar weed after a complete lawn restoration in September 2013 so it looks like we could have the same problem. By the end of January it was completely weed free but I noticed these weeds popping up by mid February. The stuff I have is very easy to pull up after a rain when he soil is very moist and it doesn't appear to be spreading from the roots. I was thinking its crabgrass that germinated in the fall and sat dormant through the winter. Only problem with that theory is that we have had several heavy frosts and a couple snows which didn't kill them. I would have thought this would have killed crabgrass, right? The seed I used was the Hogan Tall Fescue blend from the Hogan company which clearly states on the label 0% weed and 0% other crop so I'm positive this weed didn't come from the seed. I did use straw I purchased from a local company so I'm thinking if this weed is orchard grass the straw is most likely where it came from. Some of these weeds in my lawn are just individual while there are others in small groups which to me indicates they were in the straw, some as complete seed heads while others were just individual seeds. Last weekend I put out an application of Prodiamine 65 WDG (Barricade) pre em in hopes it would keep more of this stuff from germinating but it doesn't say anything about controlling orchard grass. So far I have manually pulled about 50% of it but that's not much fun on 20,000 square feet of lawn with my beat up old knees! I did spot spray a week ago with Ortho Weed-B-Gon crabgrass killer which seems to be hurting it a little. Going to wait another week and do a second spot treatment and see what happens. Here's the photo of my weed for comparison: This post was edited by ForsheeMS on Sat, Mar 8, 14 at 9:42...See Moreidentifying a grassy weed
Comments (5)Looks like Poa Annua (Annual Bluegrass). I will let you google that one and you'll get the bad news - it is a prolific SOB that produces seeds like mad and anything you might use to kill it kills your 'good' grass. The good news is that it is a cool season annual and dies out once the heat comes but then it can leave brown patches all around. A pre-emergent helps but the seeds last for years so you'd need to do it more than usual. What is the rest of your grass? Most desirable turf grasses compete poorly against poa in cool and damp weather but have deeper roots and compete well once things heat up. I have it BAD this year in my Texas Bermuda lawn and the Bermuda is just now outgrowing it. You can't cut low enough to get rid of poa but when your desirable grasses are long enough to shade the ground the poa doesn't germinate well. Your best bet right now is to water only when your 'good' grass needs it. Poa has shallow, bunched roots and likes things wet. I will guess that this booger was green and growing before your lawn came out of dormancy? One trick for getting rid of it BEFORE your good grass comes back is to get a gallon of vinegar - the 20% acetic acid type they sell at Lowes is stronger than you need. Ideally some dollar store apple cider vinegar would be cheap and easy and good for the soil. I can cut the 20% 3:1 with water and it works fine so any cheap vinegar ought to work. Put it in your tank sprayer and give each little clump a shot - oh, a drop of liquid dish detergent or baby shampoo will act as a wetting agent and coat things much better - a drop in the sprayer and shake well will do. Spray that in the morning on a sunny day and it burns up the poa. It will kill anything growing above ground - my Bermuda is a tougher grass so the amount of vinegar that burns up the poa doesn't wipe out the bermuda but knocks it back. I don't bother once the Bermuda is actively growing (soil temp up to 65). It's a pain in the ass unless you just want an excuse to enjoy the weather and get some think time but I will sit down with a bucket and yank out the poa clumps where they are really bad then throw them in the compost bin so the seeds will get cooked and broken down... this stuff is prolific as a seeder! If you are amenable to another 'natural' solution I would not mention to the neighbors, a 'high urea liquid fertilizer' will burn poa too but if you aren't into the whole organic thing then collecting your pee and spraying it in the yard might be unappealing. Looking at your grass though I would bet it is too tender to handle it just like poa so once the good grass is growing there ain't much to do except wait for heat and keep it dry - it will die out and come back in fall as your lawn starts to go dormant and it's during the dormant stage of the good grass when you can really attack that crap....See MorePlease help identify this grassy weed.
Comments (3)It's green kyllinga. You can tell by the flower head. It is a sedge like nutsedge but this one is drought tolerant and harder to get rid of than regular nutsedge. The sedge killers may hurt the bermuda but the bermuda will grow back. It's called tough love. Be sure the bermuda is well fertilized before you spray. Or you could wait until the bermuda goes COMPLETELY dormant and spot spray the sedge killer the weeds....See MoreBright Green Weed! HELP
Comments (5)The crabgrass will die in the fall after frost. So you don't have to kill it now. Herbicides will stress your grass somewhat and summer puts the lawn under stress anyway. So you have to decide whether the herbicide or the growth of the crabgrass is more stressful to your good grass. If you use an herbicide (like Weed B Gon with Crabgrass Killer), read and follow directions. I haven't used it (I've had success with pre-emergents). Some herbicides require that the air temperature be under a certain level....See Moregrass1950
