Find answers to common questions about lawn care, weed control, and pest management in Oklahoma City.
What do landscapers spray on a lawn?
Landscapers typically spray a mix of selective herbicides and professional-grade fertilizers designed to target weeds while feeding your grass. They may apply pre-emergent products to stop crabgrass and other annual weeds from germinating, plus post-emergent sprays to knock out broadleaf weeds like dandelions and clover. In Oklahoma City, lawn pros also use liquid or granular fertilizers calibrated to local soil conditions to promote strong root growth and rich color. Depending on the property, they may include treatments for nutsedge, grassy weeds, or surface insects. Everything is applied at the correct rate and timing so the lawn thickens up, chokes out new weeds, and stays healthier through Oklahoma’s heat and weather swings.

Is lawn pest control worth it?
Lawn pest control is often worth it because insects and grubs can quietly destroy turf roots and blades before you notice visible damage. When populations spike, you can see brown patches, thinning grass, and bare spots that are expensive and time-consuming to fix. A proactive pest control program helps protect your investment in fertilization, irrigation, and mowing by keeping damaging insects below problem levels. In central Oklahoma, pests like grubs and armyworms can move fast, especially in stressed lawns. Professional treatments are carefully timed and targeted, so you are not blanketing the yard with unnecessary chemicals. Over time, this approach usually costs less than replacing large sections of damaged turf.

What are signs of a struggling lawn?
A struggling lawn often tells on itself with several visible and underfoot clues. You may notice thin, patchy areas, lots of visible soil, and more weeds than grass. Color changes are common: the lawn looks dull, pale, or yellow instead of a consistent, healthy green. The ground may feel hard and compacted, or the grass may crunch underfoot in summer because roots are shallow and dry. You might also see slow recovery after mowing, bare spots that never fill in, or frequent disease spots and mushrooms. When those symptoms show up in Oklahoma City, they usually indicate problems with soil health, watering, fertility, or weed and pest pressure.

Is October too late to spray for weeds?
In Oklahoma City, October is generally not too late to spray many cool-season broadleaf weeds, as long as temperatures are still mild and the weeds are actively growing. Fall is actually one of the best times to treat dandelions, clover, and other perennial weeds because they are moving energy down to their roots. When you apply a quality post-emergent herbicide during this window, more of the product is carried into the root system, giving longer-lasting control. However, results drop off once the first hard freezes arrive or when daytime highs stay too low. A local lawn spraying service can time fall treatments around Oklahoma’s specific weather patterns.

What kills all weeds but not grass?
To kill weeds without harming your lawn, you need a selective herbicide formulated for your grass type. These products are designed to target broadleaf weeds like dandelions, chickweed, and plantain while leaving healthy turfgrass unharmed when applied as directed. Many lawn services use blends that control a wide range of common Oklahoma weeds but are safe on established fescue or Bermuda lawns. Timing matters: spraying when weeds are young and actively growing delivers better results and reduces the number of repeat applications. Always follow label instructions and avoid using non-selective killers like straight glyphosate in the lawn, as those will damage or kill grass right along with the weeds.

What is the hardest lawn pest to get rid of?
Some of the toughest lawn pests are those that damage roots underground, like white grubs, because you often do not see them until the lawn thins out or pulls up like loose carpet. Certain surface feeders, such as armyworms and chinch bugs, can also be challenging because they move quickly across a yard and cause large brown areas in a short time. These pests often require precise timing and the right product choice for effective control. Missing that treatment window can mean another full season of damage. In Oklahoma, a professional lawn pest program that includes monitoring and preventive applications usually works better than spot treating after major injury appears.

Is October too late to fertilize a lawn?
In Oklahoma City, October is often still a good time to fertilize cool-season lawns like fescue, especially early in the month while soil temperatures remain warm. Fall fertilization helps grass build strong roots, store energy, and green up faster in spring. However, for warm-season lawns like Bermuda, the window is earlier, and late fertilization into dormancy can increase the risk of winter injury. The key is matching the fertilizer type and timing to your grass species and current weather. Many professional programs include a well-balanced fall application tailored to local conditions so the lawn enters winter healthier and better able to resist weeds and stress.

What should I spray on my lawn in the fall?
In the fall, most lawns in Oklahoma benefit from a combination of broadleaf weed control and, in some cases, a carefully timed pre-emergent. A post-emergent herbicide helps clean up dandelions, clover, henbit, and other cool-season broadleaf weeds that pop up as temperatures drop. Depending on your weed history, a fall pre-emergent may be applied to reduce winter annual weeds that would otherwise appear in late winter and early spring. Fall is also a critical time for fertilization, which is often applied separately but may be part of a comprehensive lawn program. Having a local lawn spraying company build a fall plan around your grass type delivers the best results.

Is it better to spray at night or in the morning?
For most weed control products, early morning is better than night spraying. Morning applications allow you to take advantage of cooler temperatures, light winds, and active plant growth, which help herbicides absorb more efficiently. There is also time during the day for the spray to dry before any chance of evening dew, rain, or irrigation. Spraying at night can increase the risk of drift if winds pick up, and some products may not perform as well when plants are less active. Always check the label, but in Oklahoma’s climate, calm, mild mornings are usually the safest and most effective window for spraying lawns.

Can weeds be killed permanently?
Individual weeds can be killed, but keeping them gone “permanently” requires ongoing prevention and good lawn health. Even when you kill existing weeds and their roots, new seeds can blow in from neighboring properties, bird droppings, or older seed banks in the soil. A strong lawn with thick, well-fed grass naturally crowds out many weed seedlings before they become a problem. Combining pre-emergent herbicides, targeted post-emergent sprays, proper mowing height, and regular fertilization greatly reduces weed pressure long term. Over time, a professional lawn program can dramatically cut down the number of weeds, but some level of ongoing maintenance is always needed.

How to fix a lawn that is mostly weeds?
Fixing a lawn that is mostly weeds usually requires a step-by-step makeover rather than one quick treatment. Many homeowners start with a full-season weed control program to knock back the existing weed population using selective herbicides. Once weeds are under control, the next steps are improving the soil with aeration, adjusting mowing height, and adding the right fertilizer to encourage thick, healthy grass. In some cases, especially in Oklahoma’s tough soils, overseeding or even partial renovation is recommended to introduce better turf varieties. Consistent maintenance and follow-up weed control are essential; otherwise, the empty spaces left by dead weeds will simply refill with new ones.

What are the worst weeds to have in Oklahoma?
Some of the worst lawn weeds in Oklahoma are those that spread aggressively and are difficult to control once established. Dandelions, crabgrass, nutsedge, henbit, clover, chickweed, and broadleaf plantain are common culprits in Oklahoma City lawns. These weeds compete hard with turfgrass for water, nutrients, and sunlight, often thriving in compacted or thin areas. Many have deep or extensive root systems and can quickly return if not treated correctly. A targeted weed control and fertilization program, timed for local seasons, is the most reliable way to keep these troublesome species in check and maintain a thick, attractive lawn around your home.

What kills weeds down to the root overnight?
Most reliable lawn-safe herbicides do not truly work “overnight,” but some fast-acting products begin showing visible results within 24–48 hours. Non-selective herbicides can burn down weeds quickly, but they will also kill any grass they touch, making them a bad choice for use in the lawn. Selective, professional-grade broadleaf herbicides work systemically, moving from the leaves into the root system to provide deeper, longer-lasting control. While leaves may start curling or discoloring within a day or two, complete root kill usually takes several days to a couple of weeks. Patience and proper application are key if you want a weed-free yard without injuring your turf.

What kills dandelions permanently?
To control dandelions long term, you need to attack both the visible plant and its deep taproot. Selective broadleaf herbicides are designed to be absorbed through the leaves and carried down into the root, which helps prevent quick regrowth. Spot treating dandelions when they are young and actively growing, especially in fall or early spring, gives the best results. Avoid letting them flower and seed, as each plant can produce many seeds that blow across the yard. Over time, regular weed control, proper mowing, and consistent fertilization will help your grass thicken and make it harder for new dandelions to establish in Oklahoma lawns.

Is it better to pull or spray weeds?
Whether pulling or spraying is better depends on the type of weed, how many you have, and how much time you can invest. Hand-pulling can work well for a few isolated weeds, especially if the soil is moist and you can remove the entire root. However, for deep-rooted weeds like dandelions or large infestations across an Oklahoma lawn, pulling alone often leaves root pieces behind and is very labor-intensive. Spraying with a selective herbicide allows you to treat larger areas more efficiently while protecting the grass. Many homeowners use a combination: pull what is easy and visible, and rely on professional sprays for thorough, long-term control.

Can I spray weeds in September?
Yes, September is often an excellent month to spray weeds in Oklahoma, particularly broadleaf weeds that are actively growing in the cooler late-summer and early-fall weather. Treating in September helps reduce weed competition before your lawn heads into fall fertilization and winter. This timing is especially helpful against newly emerging cool-season weeds and any warm-season weeds still hanging on from summer. As always, success depends on using the right product for your weed types and following label directions. A lawn spraying company can fine-tune September treatments around Oklahoma City’s temperatures and rainfall to get the best performance with minimal stress on your turf.

Is it worth spraying weeds in the fall?
Spraying weeds in the fall is one of the most effective strategies for achieving a cleaner lawn the following spring. In fall, many perennial weeds move nutrients and energy down into their roots, which also carries systemic herbicides deeper into the plant. This leads to better root kill and longer-lasting control than many spring applications. Fall weed control also reduces the number of winter annuals and early-spring eyesores, making it easier for your grass to green up and spread. When combined with fall fertilization, a professional weed spray program sets Oklahoma lawns up for thicker, healthier growth and fewer weeds the next year.
