The Case For Tolerating Wild Violets

How to Control Weeds in Your Lawn

Because wild violets have pretty flowers that bloom early and often, not everyone regards this plant as a weed. Many homeowners choose to let these wildflowers grow in their lawns and elsewhere.

There are several reasons for tolerating wild violets in the lawn:

  • It makes for a low-maintenance lawn.
  • It avoids the use of herbicide.

Managing Weeds In Lawns

  • Identifying weeds and understanding why they’re growing where they are is key to controlling them.
  • Try to tolerate a few weeds as long as your lawn is generally healthy.
  • Some non-chemical cultural practices favor desirable grasses over weeds.
  • If you do use chemicals, different lawn situations may need different types of herbicides.
  • When using herbicides, follow the label directions exactly as printed on the product container.

A weed is described as “a plant out of place.” What may be a hated weed invader for some, might be a tolerable ground cover to someone else.

While sustainable lawns may have some weedy plants in them, having well-adapted grass varieties will help keep weeds to a minimum.

  • A few weeds in a lawn are not a serious threat to lawn health.
  • You can adjust cultural practices to keep plants healthy when controlling weeds with reduced or no use of herbicides.
  • Find out the reasons behind increased weed growth before using an herbicide to kill weeds. Killing weeds without correcting underlying problems only invites continued and often increased weed invasion.
  • Promote plant health to create a vigorous lawn that can prevent any serious weed problems from taking over.
  • Knowing which weeds are invading your lawn is important when deciding whether or not control measures are needed and when they need to be carried out. It is also important in determining the most appropriate herbicide product to use, if needed.

These steps are one example of a simple weed control plan:

Chemical Control By Weed Species

Herbicides or combinations of herbicides used to control weeds are listed, by weed species, in Tables 4 and 5. For convenience, additional information is provided on tolerant species, dates of application, and methods of application. These suggestions are not a substitute for pesticide labels. The label provides detailed information on safety and proper use of the herbicide. Read the entire label before applying any pesticide.

Control Of Broadleaf Weeds In The Lawn

Dandelion, plantain, and white clover are common perennial broadleaf weeds in lawns. Broadleaf weeds in lawns can be removed manually by pulling and digging or destroyed with broadleaf herbicides.

In small areas, some weeds can be controlled by pulling and digging. This method is best accomplished after a heavy rain or deep watering. Unfortunately, pulling and digging is often ineffective on deep-rooted weeds.

In many situations, herbicides are the only practical method of weed control. Effective broadleaf herbicides include 2,4-D, MCPP, and dicamba. The most effective broadleaf herbicide products contain a mixture of 2 or all 3 of these compounds. Combination products control a wider range of broadleaf weeds than a single compound. For example, 2,4-D does an excellent job on controlling dandelions, but is relatively ineffective against white clover. MCPP, on the other hand, provides excellent control of white clover and only fair control of dandelions. Products containing 2,4-D and MCPP effectively control dandelions and white clover. Triclopyr is another broadleaf herbicide. It is typically used on hard-to-kill broadleaf weeds.

Why Diy Weed Control Can Be Costly And Time

Many homeowners will purchase do-it-yourself home treatment options from local retailers, such as fertilizers or herbicides, for controlling weeds. Unfortunately, sometimes these individuals will apply too little or too much product, generating poor outcomes.

Chemical Control Of Broadleaf Weeds

Benefits of Organic Weed Control

Broadleaf weeds are usually controlled with selective postemergence herbicides. The most common broadleaf herbicides used in turf include 2,4-D, 2,4-DP , MCPP , dicamba, clopyralid, and triclopyr. There are many different commercial formulations and mixtures of these compounds .

*Products containing clopyralid should not be used on residential lawns, but they can be used on institutional grounds, athletic fields, and golf courses.

It is extremely important to identify the weed to be controlled before selecting one of these herbicides. All have the potential to damage trees, shrubs, flowers, and vegetables if they contact the foliage. Trees and shrubs are particularly sensitive to dicamba since this herbicide is mobile in the soil and can be taken up by tree roots.

Liquid postemergence broadleaf herbicides are available as salts and esters. The most popular salt formulation is the amine salt. The amine salt is soluble in water and suitable for spray applications. Amine formulations are nonvolatile, but they can react with calcium and magnesium ions to form insoluble salts.

How to Control Weeds on Your Lawn

Many of us want our lawns to be weed free and contain only the cultivated grass types that we would associate with a well-managed lawn which looks pleasing to the eye.

In terms of keeping weeds under control, there are a variety of things that can be done by the home owner before the application of any chemicals is considered. Any lawn management programme which brings about complete grass coverage will help greatly with keeping the weeds at bay. This ought to include regular cutting and lawn feeding several times per year, as well as routine cultural activities such as scarification and aeration.

Where practical, regular irrigation of the grass during spells of dry weather throughout the growing season will also help with maintaining healthy grass coverage. This becomes particularly apparent during prolonged dry spells, when lawns become drought stressed and the thinning turf provides a gateway for a fresh crop of weeds.

If you have a lawn full of weeds like these, then in all reality the only effective means of control at your disposal will be to use a selective herbicide. Selective, because its intended to provide effective control of the weeds ONLY and is NOT to be confused with a systemic herbicide such as those containing glyphosate. These are designed to control everything.

Managing Weeds In Warm Season Lawns

Factsheet | HGIC 2310 | Jul 13, 2022 | |

Annual trampweed is a winter annual weed that becomes established in lawns that are mowed very low and not irrigated or fertilized adequately. The fluffy seeds will blow in the wind. For more information, see HGIC 2319, Annual Trampweed.Joey Williamson, ©2015 HGIC, Clemson Extension

Bermudagrass, centipedegrass, zoysiagrass, and St. Augustinegrass are the most popular warm-season turfgrasses grown in South Carolina. Warm-season refers to the fact that they prefer the warm temperatures of spring and summer to grow. In the winter months, they do not actively grow, but become dormant and the foliage turns tan.

The Weed Control Timing Chart

Herbicides may be almost completely ineffective if applied at the wrong time of year. There is an optimum time frame to apply an herbicide to each weed. In most cases, this time is early in the weeds life cycle, but in some cases, herbicides should be applied during a different growth stage. Generally, weeds should be actively growing when an herbicide is applied. In certain instances, only a pre-emergent herbicide may provide effective control. Remembering when to apply herbicides for the many different weeds can be a challenge. The herbicide label provides definitive information concerning the turf growth stage, time of day, and weather conditions when the product may be applied, but this simple chart can help in making a plan for the timing of lawn weed control.

The Lawn Weed Control Timing Chart was developed to help remove confusion and guesswork when determining the recommended time of year to control various weeds in lawns. The chart is arranged with a list of common weeds in rows on the left, and months of the year in columns on the top of the chart. The row for each weed listed has a colored bar in the row, indicating the time frame when the weed may be most effectively controlled. Green bars indicate application time ranges for post-emergent herbicides , and goldenrod bars indicate application time ranges for pre-emergent herbicides.

Using A Lawn Weed Killer

If you have a lot of weeds to get rid of, then using the best weed killer for lawns is the most effective method of control.

Lawn herbicides are selective. This means they target weeds without killing common types of turfgrass.

Theyre formulated to be effective at killing:

  • Broadleaf weeds such as dandelion, clover, and chickweed
  • Grassy weeds such as foxtail, quackgrass, and crabgrass
  • Grass-like weeds such as nutsedge, wild onion, and wild garlic

But you still have to be careful when using them. Not all products are safe to use on all grass types. So check first to make sure your grass is recommended.

Also, stay away from non-selective weed killers containing ingredients such as glyphosate. These kill all vegetation, including your grass.

Herbicides are easy to use. Just mix the concentrate with water and add it to a good weed killer sprayer. Then make sure you soak the target weeds as you spray your lawn.

The weeds should turn brown and die. But, depending on the herbicide, the time taken can vary.

Systemic weed killers are best for killing the plants to the root and preventing them from growing back. But you have to be patient when using them, as they can take from 2-4 weeks for a complete kill.

After the weeds have died you can use a rake and tilling fork to clear the leftover plant from the soil in preparation for reseeding the area or laying sod if necessary.
