All over my lawn! What are these?

Hi all

Literally hundreds of these have popped up over my lawn since the new year. This is the first time it has happened, never before.







How do I get rid of them? Will mowing the lawn over them help or do they have to be picked out individually? Its really annoying because every year my lawn is gorgeous and this just makes it look untidy.

PLease help :gaagh:

Those seedlings in your lawn look like tree seedlings to me. Sycamore maybe. They can be a real nuisance.
You could try just mowing and see how it goes.
