Key takeaways
- Dandelions, clover, daisies, and plantain are the four most common UK lawn weeds
- Mowing below 3cm weakens grass and creates gaps for weeds to colonise
- Autumn overseeding with quality grass seed is the single best organic prevention method
- Selective herbicides work best when weeds are actively growing, between April and September
- White clover fixes nitrogen and supports pollinators, so many gardeners now choose to keep it
- Most lawn weeds indicate an underlying problem such as compaction, poor drainage, or low fertility
