Bindii
Soliva sessilisA low-growing annual weed with finely divided leaves. It grows over winter and forms prickly burrs in spring, so the time to deal with it is before it seeds.

Weeds
Common lawn weeds: how to recognise them, when they germinate in your climate zone, and how to control them without harming your grass.
Use the Weed IdentifierClover
Trifolium repensA creeping perennial with three round leaflets and white flowers in spring. It spreads by runners and is good at holding its own in lawns that are short of nitrogen.
Nutgrass
Cyperus rotundusA sedge, not a true grass. It has shiny leaves, a triangular stem and underground tubers ("nuts") that let it regrow again and again.
Onion weed
Nothoscordum borbonicumA clumping weed with narrow leaves that grows from bulbs. Each plant produces many tiny bulblets, so pulling it out usually leaves some behind.
Winter grass
Poa annuaA soft, light-green grass weed that germinates in autumn, grows through winter and seeds in spring. Prevention in autumn works far better than trying to kill it once it's up.
