Burr medic

What to look for

• Creeping stems carry leaves divided into three leaflets, often with small teeth near the edges.
• Small yellow pea-shaped flowers differ from the white ball-like heads of white clover.
• The fruit coils into a pod; the familiar burr-forming type develops hooked spines.

Confirm it before you treat it

Photograph the leaflets, flower and pod together. White clover, oxalis and several other medics also have three-part leaves. Spotted medic can show a dark leaflet mark, while black medic has a different mature fruit. Burr medic is not bindii, even when both make walking uncomfortable.

What to do next

1. Remove small plants with their crown and roots before burrs mature. Wear gloves where prickles are present.
2. Collect loose burrs and check footwear, pet coats and mowing equipment before moving between lawn areas. Avoid spreading seed-bearing material into clean turf.
3. Repair thin patches when the lawn can recover, and ask for a species- and turf-specific product match if the infestation is extensive.

Conditions matter more than dates.

Open lawn areas allow creeping stems and seedlings to establish. The coiled pod is a stronger clue than three leaflets alone; use it to avoid confusing several different weeds.

In southern references, the spiny form flowers from late winter into early summer. Scout after autumn growth begins and before spring burrs harden. Warmer areas and rainfall can shift that timing.
