Sheep Sorrel

Image of Sheep Sorrel

Problem Info

Arrow-shaped leaves, 1 to 3 inches long, form a dense rosette. Erect, upright stems grow 4 to 14 inches tall. Two types of flowers appear in midspring; one is reddish green, the other yellow-green. Sheep sorrel is also called red sorrel or sourgrass because of its sour taste. It grows in dry, sterile, sandy or gravelly soil and is usually an indication of acid soil or low nitrogen fertility. The root system is shallow but extensive and is not easily removed.

Analysis

Rumex acetosella This cool-season perennial is also called red sorrel or sourgrass because of its sour taste. It grows in dry, sterile, sandy or gravelly soil and is usually an indication of acid soil or low nitrogen fertility. Sheep sorrel reproduces by seeds and red underground root stalks. The root system is shallow but extensive and is not easily removed.

Solution Advice

To discourage sheep sorrel, test the soil pH and correct to between 6.0 and 7.0 if necessary. Improve the soil fertility by following a program of regular feedings during the growing season.
