Strange weed that has overtaken my lawn in southern NH

Nashua, NH

Good afternoon all,

I was wondering if you could all help me out. I have a very strange weed that has completely overtaken my lawn (approx. 3/4 of an acre here in southern New Hampshire). I'm not sure what it is, but, it completely chokes out my grass. Besides ripping out my lawn and re-seeding, are there any other options of getting rid of this weed, while keeping the healthy grass that is around? If anyone is familiar with this weed and has any information on how to completely get rid of it, I'm all ears. I have tried picking it out from the root source, using a broad leaf killer, etc. It just continues to come back, spread out and choke out the healthy grasses. This stuff also spreads into my plant beds as well. It's really a nuisance!

Thank you all for your help, I greatly appreciate it!! Image attached

it could be a prostate spurge. usually freezing weather kills it. applying a preemergent herbicide in the spring will keep most of it in check.

I agree with nel5397. A prostrate spurge.

You may also want to consider using Preen in your perennial beds in the early spring. Spurge throws out thousands of seeds, all of which seem to be viable, especially in dry soil.

Yes, these only affect men - very hard to root out.

this plant is growing in my neighborhood in Toronto. The look like white flowers but they are variegated leaves. It seems they grow from seeds since most of the homes in that street has the same plant. But i have never seen this in garden centre. I would like to know the name and how it is propagated.

ashamathai - I think your plant is a Euphorbia, but I don't know which one. You should start a new thread rather than adding your mystery plant to a pre-existing thread. You will get more viewers that way and increase your chances of a staisfactory outcome.
