Unknown Weed – Green With Parsley-Like Leaves
Q: An odd weed was growing in my neighbor’s centipede lawn. It first showed up last winter and now we have it. It is green and growing now and the leaves look like parsley.
A: You have lawn burweed. In December you can spray with any broadleaf weed killer. Next spring, be sure your lawn maintenance practices are top-notch. Thickly growing grass shades seeds, preventing germination, and will crowd out new seedlings. It’s a winter annual plant so preventing seed germination each year is absolutely vital. Spread a pre-emergent that contains isoxaben in early September to prevent the seed from germinating. Burweed will die when temperatures approach 90 degrees, usually in late May or early June.
