Lawn Weed Identification for Athens, Alabama

Almost every failed weed spray in Limestone County comes down to the same thing: the weed was not what the homeowner thought it was, so the product was never going to work on it. Nutsedge shrugs off broadleaf killer. Dallisgrass shrugs off almost everything. This page is how to tell them apart before you buy anything.

Turf Haven treats lawns in Athens, Alabama. We wrote this because the question we get on the phone is almost never “what should I spray,” it is “what is this stuff.” Product lists for every one of these live in the Alabama Cooperative Extension System home lawns chemical weed control guide.

The three groups, and why the group matters more than the name

Every lawn weed falls into one of three buckets, and the bucket decides the chemistry.

  • Broadleaf. Wide leaves, visible veins, often a flower. Clover, chickweed, henbit, dandelion, wild violet, spurge, dollarweed. The easiest group to kill and the one most store products are built for.
  • Grassy. Looks like grass, because it is grass. Crabgrass, goosegrass, dallisgrass, annual bluegrass. Hard, because anything that kills a grass tends to kill your grass.
  • Sedge. Looks like grass and is not. Nutsedge, kyllinga. Needs its own product, and this is the group that makes people think their sprayer is broken.

The sedge test takes two seconds. Roll a stem between your fingers. A sedge stem is triangular and will not roll smoothly. Grass stems are round or flat and roll fine. Sedges are usually a lighter, faster growing green that sticks up above the mow line within a day or two of cutting.

What kills nutsedge

A sedge specific herbicide, and nothing else. A general purpose broadleaf product will not touch it, which is why so many people conclude nutsedge is unkillable.

Two things about it that catch people out. It grows from tubers in the soil, so what you see is the top of a network, and pulling it can trigger the tubers to send up more. And it is slow. Two to three weeks to see a treated plant go down is normal, and a second application is usually part of the job rather than a sign the first one failed.

Nutsedge also tells you something. It thrives in wet, compacted ground, so a patch that keeps coming back in the same spot is often a drainage or irrigation problem wearing a weed costume.

What kills dallisgrass

Honest answer, this is the hardest common weed in north Alabama and there is no clean one application fix.

Dallisgrass is a perennial clumping grass, so it comes back from a crown that survives whatever you sprayed on the leaves. It grows in coarse, flat rosettes with tall seed heads that shoot up between mows, and it spreads by seed from those heads. Control is repeat applications over more than one season, plus stopping the seed. Anybody who tells you it goes away this summer is selling something.

The reason it beats crabgrass for difficulty is exactly that perennial crown. Crabgrass dies every winter whether you do anything or not.

How to get rid of weeds in bermuda grass

Bermuda is the most forgiving lawn grass to spray, which is genuinely useful. It tolerates selective herbicides that would damage fescue or St. Augustine, so most of what is on the shelf is safe on it when the label is followed.

Timing does more than product choice. Pre emergent in the second half of February stops the summer annuals before they exist. Post emergent handles what is standing. Both are covered by date on our north Alabama lawn care calendar.

The thing nobody wants to hear is that a thick bermuda lawn is the actual weed control. Weeds win on bare dirt. Fix the thin spots and the spraying matters less every year.

How to get rid of weeds in zoysia grass

Same principle, less tolerance. Zoysia is more sensitive to herbicide injury than bermuda and it is much slower to recover when something goes wrong, because it does not spread aggressively enough to fill a damaged patch quickly.

Read the label for zoysia specifically rather than assuming a warm season product is a warm season product. Rate and temperature restrictions matter more here. Extension’s maintenance notes on zoysia and bermuda are a reasonable starting point on the cultural side.

What kills poa annua

Annual bluegrass is a winter annual, so the real answer is the September pre emergent, not anything you spray in February when you finally notice it.

By the time it is visible as light green clumps with white seed heads in a dormant lawn, it has already set seed for next year. Post emergent options exist and they are limited and grass type specific. This is a weed you beat on the calendar or not at all. Extension covers the fall window in its fall and winter lawn care guidance.

How to get rid of dollarweed

Round, shiny, coin sized leaves with the stem attached in the middle, like a tiny lily pad. It is a broadleaf, so broadleaf products work on it, though it usually takes more than one pass.

Dollarweed is a water indicator. It shows up where the ground stays wet, so if you are treating the same patch every year, look at your irrigation schedule and your drainage before you buy more chemical.

What kills wild violets

Wild violet is the most stubborn broadleaf in this area. Heart shaped leaves, purple flowers in spring, and a waxy leaf surface that sheds herbicide.

Expect multiple applications across more than one season. Fall is generally the better time to hit it, when the plant is pulling resources down into the roots and takes the product with it. A single spring spray on violets is close to a wasted trip.

What kills chickweed but not grass

A selective broadleaf herbicide. Chickweed is a winter annual with small oval leaves and tiny white flowers, and it forms low mats in cool weather, so it is easy to kill while it is young and much harder once it has matted.

The better answer is that chickweed is a pre emergent problem. September application, and you never meet it.

How to get rid of henbit

Henbit is the purple flowered weed that takes over dormant lawns and roadsides here every February. Square stems, scalloped leaves stacked around the stem, related to mint.

Selective broadleaf products work, and they work far better on small plants in late fall than on a field of it in bloom. Same story as chickweed. It is a winter annual, so the September pre emergent is the real control and everything after that is cleanup.

How to get rid of goosegrass in lawn

Goosegrass looks like crabgrass and gets treated like crabgrass, which is why it survives. The tell is the centre. Goosegrass has a flattened white or silver base, sometimes described as a white star, and it grows in a tight rosette. Crabgrass sprawls out flat with no white centre.

It germinates later than crabgrass and it favours compacted ground, so it often shows up in the same tracks and edges every year. Later germination is why a single early pre emergent sometimes stops the crabgrass and misses this.

What kills spurge

Spotted spurge is the low, flat, fast spreading mat with small oval leaves, often with a dark spot, and stems that ooze white sap when you break them. It is a summer annual and it loves heat and thin turf.

Broadleaf products handle it. The reason it keeps coming back is that it goes from seed to seed producing plant very fast, so a patch left alone for a few weeks reseeds itself several times over in one summer.

What is the best herbicide to kill Virginia buttonweed

Buttonweed is a perennial with a deep taproot and it also reproduces from stem fragments, which is why mowing spreads it. Opposite leaves along a sprawling stem, small white flowers.

Control is repeat selective applications over a season or more. There is no single product that ends it in one pass, and any list of options is grass type specific, so the Extension guide linked above is the right place to pick from rather than a shelf at the store.

How to get rid of torpedograss

Torpedograss spreads by sharp, pointed underground rhizomes that push through everything, which is where the name comes from. Stiff, upright, blue green blades that stand out from the surrounding lawn.

This is another multi season problem. Selective control in a home lawn is limited and slow, and the honest conversation is usually about suppression and containment rather than elimination.

How to get rid of wild onion in lawn

You will smell it before you see it. Thin, hollow, upright tubes in clumps, and the mower makes the whole yard smell like onion.

Do not pull it. It grows from small bulbs and pulling leaves the bulblets behind to come back thicker. It is also waxy and upright, so spray coverage is poor, and repeat applications in late fall and again in late winter are the normal path.

What to put on your lawn to get rid of clover

Clover is a broadleaf and standard broadleaf products handle it without much fuss.

Worth knowing why it is there. Clover fixes its own nitrogen, so it competes best in lawns that are underfed. A yard that is thick with clover is often telling you about your fertility program rather than your herbicide.

Best treatment for crabgrass

Pre emergent in the second half of February, before the soil warms. That is the treatment. Everything after that is damage control.

Once crabgrass is standing you are into post emergent products that work best on young plants and get progressively less effective as the plant matures through summer. By August you are usually better off planning next February than spraying.

How to get rid of dollar spot in bermuda grass

Dollar spot is a disease rather than a weed. Small, roughly silver dollar sized bleached patches, and on close inspection an individual blade shows an hourglass shaped lesion with a tan centre.

It is associated with low nitrogen and long leaf wetness, so the first two moves are correcting fertility and watering deep in the early morning rather than lightly in the evening. Identification detail is in the Extension home lawns disease control guide.

How to get rid of brown patch

Also a disease, and close to the opposite cause of dollar spot. Brown patch shows up as larger circular patches in hot, humid weather and it is made worse by too much nitrogen, not too little.

That is exactly why guessing costs people money. Feeding a brown patch lawn because it looks hungry makes it worse.

How to get rid of armyworms in lawn

Late summer into fall. The tell is a ragged edge advancing across the lawn rather than a round dead patch, and birds working one area hard.

They can be treated, and warm season grass generally recovers when it is caught. The lawn killer is misreading it as drought and watering it for two weeks while they finish.

How to get rid of grubs in lawn, pet safe

Grub damage shows up as turf that lifts like loose carpet, because the roots holding it down have been eaten.

On the pet question, the honest version is that safety is about the re entry window rather than the word on the bag. Ask any company for the re entry interval off the label of the specific product going down, and treat a vague reassurance as a no answer. Our whole program is built around pets and kids and the rule is the same one: stay off until it dries. That is its own page.

How to treat fire ants in yard

Two approaches that do different jobs. A broadcast bait treats the whole yard including the mounds you have not found yet and works slowly. An individual mound treatment is fast and only handles the mound you can see.

Most yards here need both, in that order. Ours runs $49.

What causes bare spots in lawn, and what to put on them

Work out the cause before you buy seed, because the same bare patch has completely different fixes.

  • Shade. Bermuda will not grow in real shade and no amount of seed changes that. Either thin the canopy or accept a different ground cover there.
  • Compaction. Foot traffic and clay. Aeration is the fix, not seed.
  • Grub or armyworm damage. Treat the insect first or you are feeding the next round.
  • Dog urine. Small, dark green ring around a dead centre. Water heavily to dilute.
  • Disease. Patch shape and blade lesions tell you, see above.

For a warm season lawn, the fix is usually helping the surrounding turf spread into the gap rather than seeding, because bermuda and zoysia fill in on their own when the underlying cause is gone.

When to call somebody

If you have identified it, bought the right product, applied it on time, and the same weed is back a third season, the problem is usually not the product. It is the calendar, and keeping a calendar for a lawn is a genuine chore.

Our program runs $49 a visit, eight visits a year, roughly six weeks apart, and if weeds come back between visits you call and we come back out at no charge. We do not sell a one time spray, because a single application on a thin lawn buys a few weeks and we would rather not take money for that.

What we do not do

We do not mow. We do not treat flower beds or hardscape as part of the lawn program. We do not do termite work. If your question is about beds rather than turf, ask and we will tell you straight whether it is something we handle at your property.
