Commonly known as Common melde, goosefoot, manure weed, and fat-hen
Common Lambsquarters is a native of Eurasia that is common in gardens, waste areas and fields. It is an invasive weed that can compete with desirable crops for water and nutrients. On the other hand, it can also attract some insects such as leafminers away from crops and control the spread of disease. Lambsquarters is an edible but should be eaten in moderation as it can be toxic in large quantities.
Most Lambsquarters germinate in the spring and flower throughout the summer. Killed by frost, the plant will reproduce from seeds dropped the previous season. Seeds can live for up to 20 years before germinating. Young plants are easily pulled up by the roots. Pre and post emergent herbicides are effective. Some selective herbicides are effective and non-selective are most effective against growth.
