Common Lawn and Garden Weeds

Broadleaf Weeds

• Aggressive plants that do not resemble grass and appear on the weaker areas in your garden.
• Examples of broadleaf weeds include chickweed, dandelions, and plantain.

• Tend to grow on lawns and are hard to tackle.
• Nimblewill, wild fescue, bluegrass, and zoysiagrass are a few examples.

Grass-like Weeds

• Look similar to grass but are not really grass.
• Nutsedge, pampa grass, and Bermuda grass are a few examples.

• Quackgrass – A creeping perennial that has deep roots and broad leaves. The best way to get rid of quackgrass is to smother it or use a herbicide.
• Dandelion – They can grow in any soil type. The best way to tackle them is to uproot them completely.
• Purslane – An annual weed that grows in summer and has reddish stems with yellow flowers. It is best to remove it completely when it hasn’t developed strong roots.
• Clover – This perennial plant is disputed as a weed. To prevent growth, feed your lawns regularly, do not allow any space for clover to take over, and let the grass grow taller so that it blocks sunlight.
• Ragweed – A soft-stemmed, upright growing weed that produces a large amount of pollen. Improving the soil by adding compost will prevent its growth. Also, broadleaf weed killers will get rid of it.
• Field Bindweed – Also called creeping jenny. Visible along streams, roadsides, and grasslands. The best way to tackle them is to remove them along with roots.
• Common Mallow – Usually found in lawns, gardens, turf, and cultivated fields. It is best to pull it off when there are less than four leaves on it, or you can use herbicides to control the growth.
• Black Medic – A low growing summer annual weed that has yellow flowers. Typically found next to the sidewalks or by the roadside. Improve the soil by adding compost and aerating to prevent its growth.
• Prostrate Spurge – Also called spotted spurge, it is a summer annual with reddish stems that grow on newly established lawns and sun-baked areas. Use broadleaf herbicides to remove them.
• Yellow Wood Sorrel – An annual summer weed that resembles clover. Dig it out from the soil or use herbicide that contains triclopyr to get rid of it.
• Common Chickweed – A winter broadleaf weed found in yards, vineyards, and gardens. The best way to kill it is to remove as much of the weed as possible by hand.
• Corn Speedwell – Typically infests gardens and lawns. Use herbicides labelled to control speedwells to get rid of them.
• Broadleaf Plantain – Can be found in parks, along roadsides, and cracks in sidewalks. They have shallow roots which can be removed by hand.
