Common Weeds in Flower Beds of Lawns and Gardens
Crabgrass is an annual summer plant that spreads by seeds and nodal roots that develop in the soil. It may grow to be around 2 feet tall if not clipped. It usually occurs around the middle of spring to early summer, when the surface is warmer and the topsoil is soft.
It grows best in hot, dry environments, although it may thrive in a variety of situations. Because it is annual, it withers out at towards the end of each season and therefore must reseed itself at the start of the following warm season.
Lambsquarters is among the most prevalent flower bed weeds in North America. It is a broadleaf weed that grows in the summer and is often seen in food crops as well as flower beds. It develops fast and has seeds that are tiny enough to be carried by air.
Pigweed is a particularly troublesome annual weed. It is extremely invasive, especially in broadleaf plant crops such as cotton and soybeans.
It reproduces by seeds and is recognized by its crimson, fleshy taproot. Because it prefers warm temperatures, it emerges in the late spring season or early summer.
Chickweed is really a winter weed which prefers moist soil. Chickweed infestations are rife with plant pathogens and insects. Chickweed may generate up to 800 weeds in a single season.
Severe chickweed infestations might take up to 8 years to remove after they have become established. It grows into a thick, mat-like cover that suffocates vegetable crops and different flowers.
