what's this weed?

This is growing all over my lawn from next door.

 

Looks like Creeping Cinquefoil Kay.

 

Yes I just googled and it really looks the same. How do I get rid of it. Its coming from my neighbours garden

 

Its not specifically listed on the label of either of these, but the two most commonly available selective weed killers for lawns around here are:

Verdone Extra

Vitax Lawn Clear

Brilliant so this should kill the weed off. (Fingers crossed) may slip some over the neighbours fence.

 

Beware that using clippings from a treated lawn (e.g. composting them or using them as a mulch around other plants) will kill plants - even after 9 months or so composting ... so probably best not to use on lawns where the owners are not aware.

 

Yes, I would let them know before although considering you could hide a small child standing up in their 'garden' I don't think they will mind.
