Lambs Quarters is a quick-growing broadleaf summer annual plant in the family "Amaranthaceae” and Genus “Chenopodium" It grows through all 50 states of the US from the sea level up to 6000 feet elevation. Lambs Quarters is also called Chenopodium, and it is a favorite food in India and Pakistan cooked mixed with Spinach to enhance food taste. It usually grows on disturbed and moisture-rich soils and is considered a rich source of protein and fiber for livestock. Lambs Quarters also houses several plant viruses and bacteria on vegetables and crops. Rough estimates prove it very competitive weed that could decrease up to 48% yield when not managed properly.
Lamb's Quarters is native to Europe and East Asia. But, it has naturalized throughout the cultivated areas of the world. Lamb’s Quarter flourishes in the soil with rich organic matter and plenty of moisture. Its pervasiveness in crops, garden beds, turfgrasses, and landscapes makes it a top-notch competitor for gardens and landscapes throughout the US and its neighborhood. It also grows near waterways, distracted yards, and newly cleared forest lands in the country. Lamb's Quarters is also a giant resource hunter in warm-season turfgrasses due to the multiple applications of a higher amount of Nitrogen fertilizers.
The upper sides of the first true leaves look bluish-green, while the lower sides of the leaves are purplish-red in seedlings, while mature plants may have greyish-green leaves. The leaves that bear floral structure are narrow and square with a cut at the leaf margins and a size equal to 1/6th of an inch. The egg-shaped leaves are arranged opposite each other. Leaf edges are smooth with the shining granules that later become white powdery surfaces. Lamb’s Quarters can grow erect and tall up to 5 feet based on the moisture and nutrients available from the soil. Blooming starts during mid-spring that ends in early autumn. Tiny green flowers appear in clusters at the tips of branches. No petals are observed around granular seeds but, a white powdery coating can be seen.
Since Lamb’s Quarters is a summer annual and seed emergence takes place at 50°F. Mid-spring to late summer is often an ideal time for growth. The plants that emerge in spring can flower in summer as Lamb's Quarters takes only 6-weeks for the seed set. Infertile soils and less moisture triggers early maturity and early seed set. Lamb's Quarters is a self-pollinating plant. Otherwise, birds and pollinators also induce cross-pollination within the species. Propagation takes place only through seeds, and an individual plant produces between 70,000 to 125,000 seeds. Seeds could remain viable for several years and germinate on receiving favorable conditions.
The only cultural control for the turfgrasses is repeated Mowing throughout the growing season. Usually, the rich fertile and managed turfgrasses may allow Lamb's Quarters heavily sprout but, their flowering, seed production, and dissemination delays due to the fertility of the soil in such lawns. Mowing turfgrasses after 2 to 3 weeks clear the established stands of Lamb's Quarters, and its growth remains checked. For garden beds, a mulch will not only stop its germination but help to retain soil moisture.
