Common chickweed: Common chickweed is a mat-forming weed with tiny, star-shaped white flowers. This annual thrives when conditions are cool and moist. Mouse-ear chickweed is similar, however, this weed is perennial with hairy stems and leaves, and is more tolerant of summer heat.
Broadleaf plantain: Broadleaf plantain is a low-growing perennial. It has broad leaves with prominent veins and may smother lawn grass if left untreated, which generally calls for maintaining thick lawn coverage.
Dandelions: Dandelions are well known in many lawns and gardens– their fuzzy yellow blooms popping up nearly anywhere. While their deep taproots make them difficult to control, they generally spread through their easily recognized white, fluffy seedheads.
How to Identify Weed Types
Crabgrass: Crabgrass is a homeowner’s worst nightmare, creeping up throughout the lawn. This summer annual lies flat to the ground and has reddish purple stems (both smooth and hairy). It forms slender spike-shaped seedheads just below mowing height, making it difficult to manage.
Common nettle: This is prolific in soil that borders gardens and open fields. This perennial weed has many varieties, including stinging nettle. While it may look like an ordinary, hairy weed with attractive little flowers, it can cause a very painful sting if you touch it. Nettles can often be aggressive spreaders, with creeping roots.
One of the best ways to identify lawn weeds is by looking closely at the soil in your landscape. Many common lawn weeds can be found growing in certain types of soil, making this an excellent way to identify specific types you may have growing in your landscape. Here are some of the most commonly seen weeds:
Knotweed: Knotweed is an annual weed, common along sidewalks. It usually thrives in dry, compacted soils. Knotweed forms a tough, wiry mat of stems and blue-green leaves with small white flowers. It is often confused with spurge, however, this weed does not produce a milky sap. It does produce numerous seeds, which can be reduced with annual aeration.
Type: Broadleaf perennial
Appearance: This common lawn weed has a long taproot; leaves are deeply notched. Yellow flowers mature into puffballs. Dandelion seeds are like parachutes that fly away in the wind, helping them invade new spaces in lawns and garden beds.
Control: Mulch your garden to prevent purslane or use a preemergence herbicide in the spring. Pull plants by hand or spot-treat with a nonselective postemergence herbicide.
Where it grows: Dry, sunny landscape and garden areas
Size: To 6 feet tall and 3 feet wide
