Common waterhemp, a weed that grows during the summer, can reach heights of up to 8 feet. It features glossy, alternating leaves that can vary in shape from oval to lanceolate. The stems, which lack hair, can come in bright colors like red, pink, or green.
This weed is dioecious, which means that there are separate male and female plants. Male plants release pollen, while female plants produce seeds. Astonishingly, a single common waterhemp plant can produce up to 500,000 seeds, which can stay viable in the soil for up to a decade.
Known for its competitiveness, common waterhemp can outcompete crops for essential resources such as water, nutrients, and sunlight. It can also host diseases and pests that can harm crops.
If you spot common waterhemp in your field or garden, it's important to take action to control it. There are various herbicides available to manage this weed, but make sure to use one that's specifically labeled for common waterhemp. Cultural methods like hand-weeding or mowing can also be effective.
Common waterhemp is a serious problem as an invasive weed that can severely damage crops. Identifying this weed and taking measures to control it will safeguard your crops and your profits.
