Weed Control Tips For Your Lawn

Share This With Your Friends

Below are some of the different types of weeds to identify that could be growing in your lawn and some weed control tips:

  • Annual Bluegrass:
    • Yellow/light green color
    • Boat shaped leaves
    • Grows in clumps

    You may choose to manage annual bluegrass rather than try to eradicate it. Because its most distinct difference is its yellowish color, regular fertilization of your lawn can help mask its presence. Any dead patches in your lawn must be seeded quickly to prevent annual bluegrass from growing back.

  • Virginia Button Weed:
    • Grows low
    • Perennial weed
    • Long, pointed leaves that grow opposite stem and other leaves

    If any portion of its below-ground-stem remains after hand-pulling or herbicide application, it can produce another plant. Controlling Virginia Button weed with herbicides usually requires more than one application in the same season.

  • Smooth Crabgrass:
    • Dull-green color
    • Sprouts coarse grass

    Thriving in cool climates, quack grass flourishes in under-fertilized lawns. It can quickly spread from neighboring yards, but it often hitches along with nursery stock, or contaminated mulch and topsoil. There are no herbicides designed for quack grass. If you see a plant, remove it right away or spot-spray it with an herbicide glyphosate (which will kill all green).

  • Spotted Spurge:
    • Broad-leaf weed
    • Spreads rapidly in dense mats
    • Red spots on leaves

    Common in high-traffic areas, the spotted spurge is a good indicator of compacted soil and will even grow in the cracks of sidewalks if it has enough moisture. It thrives throughout the spring and summer. Eliminating compact soil and ensuring proper mowing height will create a healthy lawn, resistant to this weed. Herbicides in the spring can prevent its initial growth, and are effective when the weed plant is young.

  • Large Crabgrass:
    • Perennial
    • Light green in color
    • Thrives in a dense lawn

    Apply herbicide in the spring, before soil temperatures become ideal for growth. If crabgrass has already started growing, a different variety of herbicide designed for mature plants is needed. Eliminating mature plants in the late summer is very difficult, but they will die with the first frost.

  • Broad-leaf Plaintain:
    • Broad, spoon-shaped leaves
    • Small celery-stalk-like stems

    Broad-leaf plantain is not easily pulled from the ground because of its thick taproot. Even when treated with an herbicide, broad-leaf plantain often has large carbohydrate stores in its roots which allow it to survive. The leaves may shrivel and disappear after herbicide application, but the weed may regrow within a few weeks.

  • Dandelion:
    • Bright yellow flowers
    • White, fuzz ball seed-heads
    • Feather structure that can float a long distance on a breeze

    Apply herbicide in fall, just before or right after tree leaves fall, The herbicide’s active ingredients move directly to the root system, which is the only part of the weed that’s still growing at this time. You won’t see many dandelions dying in fall as the plant stores energy for next spring, but be assured the herbicide is killing the root system.

  • Dallis Grass:
    • Wide leaf blade
    • Grows in clumps
    • Wide diameter
    • Unattended, weed develops a heavy stalk

    Dallis grass is a tough weed to control once already growing in your yard. There are very few herbicides, especially those available to homeowners, which will selectively control Dallis grass within other warm-season grasses. The active ingredients foramsulfuron and sulfosulfuron have been shown to provide some control.

These are all weed control tips that can be used in helping you identify and control the weeds that might pop up in your lawn.
