Weed control in autumn is one of the best things you can do to your lawn. You can create lush lawns by treating weeds in the fall, regardless of whether you are working with cool- or warm-season turf. Fall treatments can be used to kill perennial and annual weeds, and they can even be used as a way to eradicate perennial invaders like clover and dandelion.
Different types of weeds
The winter annual, a type of weed, germinates in the late summer or early fall. They can grow from fall through winter heat spells and then into the spring. They germinate in the middle to late spring just before daytime temperatures rise. Henbit, Annual Bluegrass and Chickweed are all examples of winter weeds.
Fall-germinating weeds such as Chickweed and Henbit are what you should be targeting when you treat your lawn. Although Dandelion germinates in autumn, it is less common than in spring.
Perennial weeds can also be controlled in fall, as this is the season when perennial weeds are most active, as per lawn care experts. Treating perennial weeds in fall with herbicide will move the chemical from the leaves to the roots, effectively killing the weed at its root.
Timing and Treatment
You will need a combination of a pre-emergent and post-emergent herbicide if you are using fall weed treatment to kill both perennial and annual weeds. Because some weeds may already be present, the post-emergent herbicide can kill them. However, weeds that are still growing will be killed by the pre-emergent.
Depending on where you live, the timing of your application will vary. For northern areas, you should treat your lawns by Labor Day. However, the warmest areas might apply until October.
Air temperature is a key factor in determining the best time to apply herbicides in your area. Herbicides work best when the air temperature is at least 50 degrees F. You can also seek out the help of a pro from Conway Lawn Care Services to ensure proper timing. They will know the best time for your location.
Annual Bluegrass is a common problem in warm-season lawns and should be treated. Crabgrass can invade both cool- and warm-season turf. Crabgrass is a seed-setter that can be found throughout the year. It’s worth taking the time to apply a pre-emergent herbicide to stop any late-season-released seeds from germinating.
Crabgrass preventer is the best treatment for Annual Bluegrass and Crabgrass. This pre-emergent herbicide combats grassy plants and can be used in spring or autumn. These products are not available year round in most regions. It’s best to buy a Crabgrass Preventer in spring if you are certain you will be dealing with weeds during fall.
Wild Onion, as well as its relative Wild Garlic, could be used to punctuate dormant warm-season lawns using brightly colored exclamation points. These weeds can be eliminated with post-emergent herbicides. The lawn Burrweed, a winter-annual weed that plants spurred seeds in spring and makes mowing a lawn difficult for both people and animals, is an annoying weed. This prickly weed can be controlled by a fall application of a pre-emergent herbicide.
Apply a post-emergent herbicide to perennial weeds like Knotweed, Plantain, Dandelion and Clover in the fall to kill them directly at their roots. This will reduce the number of these weeds in spring.
