Funny you of only a few see my view. I have so many "green" that it can start green early and finish late in the winter, if its not green all year, which is A Good Thought. But some get aggresive like this one, which is not responding to my efforts toward balance. I think it is a form of speedwell.
It could be. I'd just pull it out if you don't want it. We don't bother much with our lawn it's a mixture of everything. But I read that if you feed the grass it could stifle the other plants that are growing.
Just what my husband says..and also says don't dig all them out and make bald patches everywhere..at least its green. so is some molds...
Husband had just cut the lawn..haha..lawn that's a joke....here it is at it's best.. I have a lot of a clover creeper type.weeds..plus thistles, daisies, creeping buttercup and dandelions and some like yours @Dirtmechanic with the fine lots of fern like leaves in miniature and quite similar to my Californian Poppy's or Parsley. I can see you have some chickweed also. .. the large leaves in your photo approx. in the centre base, looks like something I have, it has small pleasant mauve flowers and deep roots, I have seedlings of these everywhere, so do spend a lot of time removing them whilst they are still harmless babes.hoping these are not what we have.. which is a small bindweed....they have deep roots also.. this is the temporary answer though... or he will eat any stuff also... ...must run got weeds to study......
