General Information: Common Sorrel is a perennial weed that belongs to the dock family. It is rarely a problem in well maintained lawns, being more common in low maintenance lawns throughout the UK. The Common Sorrel can grow to nearly 1 meter high.

Leaf: The leaf is oblong in shape bourn on a short stalk. The ears at the base of the leaf point downwards giving it an arrowhead effect.

Flower: Common Sorrel flowers between the months of May & June with small green flowers than turn red as they mature.

Preferred habitat: Common Sorrel prefers soils with a low pH (acid)

Control: Hand weeding is the preferred method for this weed if only a few plants are present in the lawn taking care to remove the roots. Regular mowing should discourage this weed as it doesn't like close mowing typical of lawns.

If chemicals are to be used choose a selective weed killer with MCPA or a 2,4-D mixture and a repeat application 6 weeks later will be necessary.
