Description
European wood sorrel is an invasive perennial weed characterized by its clover-like trifoliate leaves and small yellow flowers. It spreads both by seeds and small underground bulbs, making it difficult to control and allowing it to quickly form dense colonies.
Family: Oxalidaceae
Type: Annual or perennial
Appearance Season: Spring to autumn
Causes
Wood sorrel thrives in poorly drained soils and thin lawns, often made worse by overwatering.
Prevention
- Improve drainage and avoid excess moisture.
- Overseed bare spots to thicken the lawn.
Control
- Manually pull out the plants, making sure to remove the rhizomes as well.
- Mow regularly to prevent seed formation.
- Overseed damaged areas if necessary.
