landscapingWhat You Need To Know About Winter Weeds In Your Charleston, SC Lawn


The winter season is near and the color of your lawn and landscaping is brown aside from the pesky dallisgrass and henbits that pop up in your yard. You’re probably wondering how they got there.

Winter weeds such as annual bluegrass, dalligrass, corn speedwell, henbit, and hairy bittercress survive in a poor turf environment. Many of them begin to germinate during the fall, create into a full blown weed when the colder season comes and to continue to propagate.

During this time, you have three methods of attack. Manually pull the weeds out of your yard, apply a post emergent herbicide, or renovate your lawn and make it denser and healthier so it’s more resistant to weed growth.

Lawn care and landscaping tips for winter weeds in your Charleston, SC lawn

  1. Identify the type of weeds that are plaguing your lawn. Always remember that there is a specific herbicide for every type of weed. Weeds can be:
  • Grass weeds – They look a lot like grass but instead of growing up in the soil, they branch out. These weeds can either be perennial, biennial, and annual.
  • Broadleaf weeds – They have a taproot that comes with short stems, flowers, and broad leaves. They can also be perennial, biennial, or annual weeds.
  • Sedges – They come from tubers, roots that branch out, and seeds. They come with 3-sided stems and they tend to grow higher compared to normal grass. They resemble a small river reeds instead of a grass plant. These weeds are difficult to eliminate because of their seedlings, rhizomes, and nutlets.
