WeedsWeeds are the enemy of lawns everywhere and can quickly show up even in the best-kept lawn. Making maintaining a beautiful, healthy lawn harder than you think. Weed control is a common challenge for the home landscaper, and even the best gardeners and landscapers continually combat these persistent pests. Why? Because weed seeds easily travel from one area to another by wind, rainwater, animals, human traffic, and even lawn and garden equipment.

Since weed seeds are easily transported, they can pollinate different lawn areas, causing the weeds you thought you had killed in one area of your grass to start to grow again in another area. Weed seeds can also remain dormant for several years before they develop. Other weed seeds take time to reach the soil’s surface and get proper sunlight and moisture before they germinate.

The health of your lawn and its ability to grow and look beautiful depends on how you can identify problems in your lawn and how you choose to respond to the health of your lawn. You are best equipped to fight weeds when you can identify common weeds and the ways to successfully get rid of them.


Weed classifications and weed identification are the first steps to successful weed control.

There are three main classifications of weeds:

  • WeedsAnnuals grow and produce seeds, then die within a single year. Some annuals may survive a second year in warmer climates. Annual are the easiest to kill.
  • Biennials live for two years. The first year is vegetative development, and the second year is flowering and seed development.
  • Perennials live from season to season and produce seeds annually.

Weed Identification & Characteristics

Anything growing in your lawn that isn’t part of your lawn’s normal growth can be considered a weed. Even flowers growing in the yard or grass can be regarded as a weed. However, botanically, there are three types of weeds:

Grassy Weed

Grassy Weed is identified by how it resembles grass in how it looks and grows, one leaf at a time. They are true grasses. Grassy weeds look like grass blades and are considered invasive when they show up in your lawn.

Examples include Crabgrass, Foxtail, Annual Bluegrass, and Goose Grass

Sedge Weed

Sedges also look and grow like grasses but are not grasses. Sedges have solid un-jointed stems and are usually found in wet areas. Sedges are aggressive rapid growers and very hard to control.

Examples Include: Yellow and Purple Nutsedge, Wild Onion or Garlic, and Star of Bethlehem

Broadleaf Weed

These are the most common found in gardens. Broadleafs are identified by leaves that appear broad and flat (not grassy or needle-like)

Examples include dandelion, clover, ground ivy (creeping Charlie), oxalis, chickweed, dollar weed, henbit, plantain, and thistle.


Weed Control, by definition, is the botanical component of pest control, which attempts to stop weeds from reaching a mature stage of growth. All weeds, but particularly mature ones, can take over weak areas of your lawn and landscape.

Common weed control practices are soil cultivation, mulching, and herbicide application. The best way to control lawn weeds is to grow a lush and healthy lawn. But even plush and healthy lawns can and will have weeds. Fortunately, there are a few proven methods for reducing and controlling weeds.

Proven Weed Control Methods

Weed Control By Hand

  • Manually removing unwanted weeds by hand or with garden tools is the most selective and environmentally friendly way to control weeds. Here are some tips to keep in mind when using this weed control method:
  • It is much easier to remove them after a good rainfall.
  • Remove a weed as soon as it shows up.
  • Pull at the base, lifting out as much root as possible.
  • For larger weeds with extensive roots, like thistles and dandelions, use a garden fork, spike, or narrow trowel.

Weed Control & Prevention By Herbicides

Manual weed removal isn’t a practical method for large areas or overgrown places with weeds. The best option may be to use herbicides. When done correctly, herbicides effectively combat weed invasion and eliminate weeds. The challenge for homeowners is correctly identifying the weed type in their yards and understanding the best herbicide type to use at the proper time of the year during a weeds growth cycle. There are two types of herbicides broken into two categories and broken down into two nest times. Using the wrong herbicide can damage and even kill healthy lawns.

There are two types of herbicides:

  1. Systemic herbicides enter the plant through the roots and leaves and travel through the inside of the plant.
  2. Contact herbicides kill from the outside and work their way into a plant. Contact herbicides kill the weed by reducing its ability to feed itself through photosynthesis.

Within these two categories, herbicides may also be selective or nonselective:

Selective herbicides kill only certain plants and only work when applied as directed. These products remove weeds without destroying the lawn where the weeds grow.

Nonselective herbicides kill all plants they come into contact with. These are best used when preparing to establish a new lawn. When used, all living vegetation can be removed from an area, which gives you a clean slate to work with.

Lastly, herbicides are either pre-emergent or post-emergent, and the application timing is crucial. Herbicide application too late or early only wastes the herbicide.

Pre-emergent herbicides are designed for application before the targeted weed germinates and are an effective preventative method for controlling weeds. Pre-emergent herbicides establish a chemical barrier that doesn’t kill established plants but is great when used for preventative measures. The protective barrier breaks down in six to eight weeks, requiring proper timing to be effective. It is a best practice to apply them early in the season. Use caution during application because pre-emergent weed control may harm some plants and turf grasses.

Post-emergent herbicides are designed to control weeds that are already growing. All contact weed killers are post-emergent. It is best to apply post-emergent later in the growing season, after weeds have grown but before they seed.
