Common Lambsquarters Defined

Lambsquarters is an annual weed that grows in many parts of the world. It can grow as tall as 6 feet but 3 feet is more typical. It can produce thousands of seeds and is identified by a white powdery coating and triangular or diamond-shaped leaves.


Weed or Dinner? Lambsquarters is a common weed in many parts of the world. Strange as it may seem, many people consider it a delicacy. After all, it's a close relative to spinach, and is reported to be rich in Vitamin C and A, as well as calcium. Of course, this raises a dilemma: Pull it out? Or put it in a salad?

Prevention and Maintenance

Help Prevent Lambsquarters. A healthy, maintained lawn is the first defense against lambsquarters. A well-fed lawn grows thick and is better able to crowd out weeds and prevent weed seeds from germinating by blocking sunlight's access to the soil.

How to Control Lambsquarters. You can apply a broad-leaf weed control, such as Ortho® WeedClear™ Lawn Weed Killer Ready-to-Use with Comfort Wand to control lambsquarters in your lawn. Of course, before you apply a control, you might want to nibble on a leaf to see if you like it. Who knows? Maybe you'd rather have it on your dinner plate.
