I’ve just seeded a lawn about four weeks ago, and two days in I saw some green growth. I thought it was one of the clover varietals, but it turns out to be a plantain weed.

Fast forward, it has spread across the lawn and is choking out the new seedlings. Problem is, I underseeded and had to add more so I still can’t step on the lawn without damaging new seedlings.

Should I manually remove by hand and potentially kill new seedlings, or let it continue to run rampant and pull it out when the lawn can take me kneeling on it (3+ weeks)

  • How do you feel about chemicals? Weed-and-feed would make short work of that stuff. – Harper - Reinstate Monica Jun 11 at 16:44
  • I will try that when it has a few more weeks - The lawn had to go undergo a second seeding, so there are young seedlings that you can’t see in other areas that wouldn’t live through weed-and-feed – beeudoublez Jun 11 at 20:15

That looks more like violets than plantain (too high to be plantain, which is about a half-inch tall rosette at this point in the year, assuming that you're in the Northern Hemisphere). The first photo also shows something with a fern-like leaf (Queen Anne's Lace maybe?). The grass itself looks old enough to walk on, so if you're careful you can try to manually remove the violets, but you'll have a heck of job trying to eradicate them - no chemicals that I know of will kill violets (and an herbicide at this time is likely to harm the lawngrass).

EDIT - Well, the third picture shows that they're not violets. The venation on the leaves in that photo shows, also, that the weeds are not plantain either (plantain leaves don't have a central vein). They're certainly quick growers, which has me thinking "annual". Because they were already in the soil when you reseeded it, I also think they're either a common weed in the PNW or native to the area.

Whether annual or perennial, keep those plants from flowering and setting seed. I would also try an herbicide in a few weeks (probably something like Weed-B-Gone) if you don't want to hand-pull them.

  • Thanks, I added a third photo to make it clear what the leaves of the weed look like. I googled the violet and didn’t see a matching leaf pattern, but am not an expert. And yes, we are in the PNW. – beeudoublez Jun 11 at 2:21

I also think it is not a plantain.

I would mow the lawn regularly. As you see, the weed is tall, leaves exit the steam from a relatively high position. I would expect that such weeds will not survive if you cut often their leaves. The worst weeds are the the weeds which make a lot of stolons, ant they run lower on grass.

So mow your lawn regularly (maybe often then normal, and maybe the first time on lower setting). After you did it for one or two months, you should check again: maybe you may need to add some lawn seeds (and/or lawn fertilizers).

  • Thanks. Given there are still new seedlings that would get killed by walking on it, I’ll have to wait to mow. For now I’ll see what I can get by leaning from the path over to the weeds! – beeudoublez Jun 11 at 20:17
