Weed idenfication, please

I'd appreciate any help in identifying - and treating - this small but persistent weed. Possibly related to Oxalis?

That's a very blurry picture, but I see crab grass and black medic. And maybe some nutsedge.

Re: Weed idenfication, please

Apologies! Didn't see the second part! It does really well in compacted soil. It grows really well in my walkways of the garden.
Treatment for compacted soil is aeration.
It can also indicate poor soil that lacks nitrogen. You could feed your lawn.
They are really close to the ground, and that's where they make seeds, so frequent low cutting won't help.

Lindsay:

Many thanks for both replies, and apologies for the poor photo quality (apart from the soil condition!). Is crab grass the small petalled "flower"?

but I'm not quite convinced that any of those correspond to the little flowering weed you were asking about. A better picture would help.

It looks similar to Spurge. Hard to get rid of.

Re: Weed idenfication, please

It looks a little like one of the chickweeds.

Depending on the grass post emergent weed killers can work.

However, if you have more weeds than grass it is probably better to start over. Use a non-specific herbicide, dig the remains out, water, let the weeds sprout, kill them again and repeat until weeds don't sprout (at least 3 times) before amending the soil and replanting the grass

You could just keep mowing low and before the weeds go to seed and gradually pull the weeds out by hand. This is a tedious job and takes dedication. You will have to commit to a bucket of weeds a day for as long as it takes and you will probably have to go over the same area more than once.
Happy gardening in Hawaii. Gardens are where people grow.

Re: Weed identification, please

Thanks for all your comments and advice. Could it be chickweed, as suggested? I hope these two additional photos might help to confirm a diagnosis!
