How do weeds affect plant growth?
Answers
Answer:
While some weeds are not particularly aggressive and blend in with the surrounding plants, making them hardly noticeable, others are distinctly destructive. Invasive weeds are often very noticeable with different textures, colors and growth habits. These weeds can overtake your lawn or garden in a single growing season leaving it unattractive and sparse. Some weeds can also be harmful if eaten by pets and livestock.
Plants that are not necessarily considered a weed in the true sense, can also wreak havoc on neighboring plants by attaching themselves and sapping its nutrients. These parasitic plants are either stem or root parasites, with the root variety being more common. Mistletoe (Viscum album) is a prime example of a parasitic plant that attaches itself to a host plant in order to obtain water and nutrients. Mistletoe can leave a host plant weak, causing it to eventually succumb to starvation, disease or pest infestation.
Weeds are undesirable plants that compete for nutrients and other elements with agricultural plants. As a result, they harm crops by interfering with their growth.
Weeds compete with the primary crop plant for air, water, sunlight, and nutrients in the soil, depleting the main crop's resources. They're also useless to humans. As a result, they hinder the plant's growth, requiring their removal.
