Nutsedge is one of the most hated weeds for most gardeners, but also the most common. The plant resembles a group of grass blades with a distinctive, triangular shape. Nutsedge often appears slightly darker and taller than the surrounding grass in the middle of a yard. Unfortunately, many herbicides that effectively kill nutsedge also kill wanted grass. When applying herbicide to yellow nutsedge, it's crucial to target only the plant itself. Yellow nutsedge is an extraordinarily difficult weed to eliminate from your yard.
Dandelions are easily identifiable for most people, even those with no gardening experience. Children especially love the little flowers of these weeds. The flower is obvious in the middle of a lawn with its bright yellow flower. After appearing, dandelions are best killed with a broadleaf herbicide. While weeding by hand can work, dandelions have one long root that makes them particularly difficult to remove entirely by hand.
Crabgrass is common in the United States and is best treated after it appears, to kill the seeds before they spread. A decent post-emergent herbicide helps eliminate the crabgrass. This plant appears every year and spreads extremely quickly. Crabgrass, if ignored, can take over your lawn in a single season. Crabgrass looks similar to most lawn grass, except the slender leaves are a light green.
Many different types of clover exist, all of which are prolific running plants. This means lawns that are not healthy are easily taken over by the weed. Clover blooms in early spring and appears with round leaves in groups of three or four. Clover goes dormant during drought or cold weather, but it does not die. Once the weather improves and the area is watered, clover returns. A broadleaf herbicide helps get rid of the weed after multiple treatments.
