FEATURED WEED
Yellow Woodsorrel Oxalis stricta
Description This perennial thrives in dry, open turf sites, and it often invades lawns that are stressed from insect, disease or maintenance issues. It is typically recognized by its heart-shaped leaflets, which also resemble clover. In the spring and summer, it produces yellow flowers with five petals that flare outward. Leaves fold down at night and open during the day to harvest sunlight.
CONTROL TIPS
Oxalis, also known as yellow woodsorrel, can be controlled with postemergence herbicides containing triclopyr — such as Turflon® Ester Ultra specialty herbicide. Yellow woodsorrel is a perennial broadleaf weed and is capable of living for more than two years. Proper fertilization, mowing and irrigation are necessary to promote healthy, weed-free turf.
