How to Get Rid of Doveweed (Identification, Prevention, and Control)

Doveweed or dove weed croton?

Two different plants share the name, and which one you have depends a lot on where you live. The lawn weed in this article is Murdannia nudiflora, a glossy, grass-like creeper of wet Southern turf. Out West and across Texas, "dove weed" often means a croton. The U.S. Fish and Wildlife Service lists Croton texensis under the common name doveweed, and Texas A&M describes that plant as an annual with grayish to yellowish green leaves, 1 to 4 feet tall, whose seed crop is "very valuable to dove, quail and other seed-eating birds." In California the name goes to turkey mullein (Croton setiger), a low greenish-gray mat covered in dense pale hairs that prefers dry, disturbed ground.

The quick test is texture and site. Fuzzy, gray-green, and growing in dry, sunny ground points to a croton, a native plant whose seed feeds doves and quail. Shiny, hairless, bright green blades creeping through a soggy patch of St. Augustine or centipede point to Murdannia, and everything below is for that one.

Why Doveweed Is So Hard to Kill

Understanding why doveweed wins is what separates people who beat it from people who fight it all season. It has three advantages working together.

It loves wet soil. Doveweed thrives where soil stays soggy from overwatering, poor drainage, frequent rain, or a low spot that puddles. That habitat stresses your desirable grass while giving doveweed an open, sunny, moist seedbed. An outbreak is usually a drainage message, not a random invasion.

Its leaves shed sprays. The same waxy, slightly succulent surface that makes doveweed look glossy also causes herbicide droplets to bead up and roll off, so a single light application often does little. This is why repeat treatments and the right timing matter so much.

It germinates late and in waves. Doveweed comes up later in the season than crabgrass and most summer annuals, and it does not all emerge at once. New seedlings keep appearing for weeks, so one treatment rarely catches the whole population. On top of that, the creeping stems root at the joints, which means mowing or pulling can chop and scatter pieces that take root and spread the patch.

Its seed outlasts your patience. UF/IFAS notes that doveweed growth slows once temperatures fall below 70°F, and that is usually when it sets seed. Those seeds can survive in the soil for several years, which is why UF tells turf managers to plan doveweed control over two or three years. A summer annual dies back with the cold, so a clean-looking lawn in January only means the next wave is waiting in the soil.

Step 1: Fix the Moisture First

This is the highest-leverage move against doveweed, and it costs nothing but attention. Skip it and you will be spraying forever.

• Water deeply and infrequently. Let the top inch of soil dry between waterings instead of running light daily cycles that keep the surface constantly damp. Doveweed struggles when its favorite wet habitat dries out.
• Correct drainage and low spots. Track down areas that puddle after rain, downspouts dumping onto the lawn, and sprinkler heads that overshoot or leak. Core aerating compacted soil also helps water move down instead of sitting on top.
• Mow a touch higher and keep turf dense. Taller grass shades the soil and starves doveweed seedlings of the light they need, and a thick stand leaves no open ground to colonize. Do not scalp the lawn, and avoid mowing wet doveweed, since cutting its fleshy stems can spread rooting fragments.

Mowing heights that help the grass win

Mowing is where doveweed quietly gets its edge. UF/IFAS says turf cut too short and too often pushes doveweed leaves to grow flat to dodge the mower blade, and those flat leaves shade out the grass underneath. Height of cut, which is simply the mowing height, is the fix. Here are UF's numbers for the grasses doveweed invades, with the one-third rule on top: never take more than a third of the blade at once.

Set the deck at the top of your grass's range while you are fighting doveweed. UF also notes that a light to moderate nitrogen feeding with or right after a herbicide application helps the turf recover and close the gaps faster.

Step 2: Prevent It With a Well-Timed Pre-Emergent

Here is the part most guides bury: doveweed is far easier to prevent than to kill once it is established. The catch is timing. Because doveweed germinates late, once soil temperatures reach 65 to 70°F in late spring, UF/IFAS warns that a February or March crabgrass pre-emergent may be fading right when doveweed comes up. University extension programs recommend a split or sequential program, a first application just ahead of that soil temperature and a second about 45 days later, so the barrier is still active when doveweed actually emerges.

Getting pre-emergent down is like getting the tarps on before the storm. Once the rain is falling, you're late. Clemson publishes its indaziflam (Specticle G) dates by region, and they make a good rough guide for the rest of the Southeast.

Further south the soil usually warms sooner, so let a soil thermometer move those dates. UF/IFAS adds two more options for a split program: dimethenamid-P (Tower) at two applications 5 to 6 weeks apart, and S-metolachlor (Pennant Magnum), which on St. Augustine is registered only for sod farms. Soil-acting products need water to reach the seed zone. The Hi-Yield atrazine label, for example, calls for rain or irrigation within 7 to 10 days to stop weeds from seed.

Step 3: Post-Emergent Control by Grass Type

If doveweed is already up, the safe product depends entirely on your turfgrass, and this is where people cause real damage by spraying the wrong thing. Here is the extension-backed breakdown.

• St. Augustinegrass and centipedegrass: these are the most doveweed-friendly grasses to treat. Atrazine gives good to excellent control and can be used on both, applied after full spring green-up. A product containing thiencarbazone, iodosulfuron, and dicamba (sold as Celsius WG) gives good control, and Clemson calls it the only doveweed product you can use on warm-season lawns during spring green-up. A standard three-way broadleaf product can also be used, but only at a reduced rate, because both grasses are sensitive to it. UF notes some three-way labels exclude Floratam St. Augustine entirely.
• Bermudagrass and zoysiagrass: these tougher grasses tolerate a standard three-way broadleaf herbicide at the full labeled rate, and Celsius WG is also labeled for them. UF/IFAS adds metsulfuron-methyl plus dicamba as an effective combination that is safe on both. Keep atrazine off growing Bermuda: UF says it will significantly harm the grass, and consumer atrazine labels allow it on Bermuda only while the lawn is dormant. Simazine works the same way as atrazine and UF lists it as safe on Bermuda.
• Bahiagrass: this is the honest gap. No university extension source recommends a doveweed-specific herbicide that is safe on bahia, because the products that work on doveweed are not labeled for bahia. If you have a bahia lawn, lean entirely on the moisture fix, dense turf, and careful spot removal, and do not gamble with a product that can wreck your lawn.

Whatever your grass, plan on more than one application a few weeks apart, since doveweed's waxy leaves and staggered germination defeat single treatments.

Here is every product the extension services and labels name for doveweed, lined up by grass. Ratings are the extension service's own words.

What the Celsius WG label says about doveweed

Celsius comes up in nearly every doveweed conversation, so here is what the label says, straight off the Envu sheet. Doveweed sits in the label's hardest tier, controlled at 0.113 oz of product per 1,000 sq ft, and the label caps the whole year at 0.17 oz per 1,000 sq ft. Do that math and you get one full-rate application plus a follow-up at roughly half rate, which is exactly how a stubborn doveweed patch tends to play out. For a spot or zone job, the label mixes 0.057 to 0.113 oz into 1 gallon of water, and that gallon covers up to 1,000 sq ft.

Expect weeds to stop growing within hours and die over 1 to 4 weeks, faster when soil is above 65°F and the weeds are not drought-stressed. Do not mow until the spray has dried, and know that rain before it dries may mean a retreat. Heat still matters: the label warns that spot treatments on St. Augustine above 90°F can cause temporary growth regulation, and it bans spray adjuvants, such as surfactants, above 90°F. Spray early on a mild morning and let the label's numbers set the rate.

What Most Guides Get Wrong

Most doveweed articles tell you to spray a broadleaf weed killer and move on. Here is what actually decides whether you win.

Prevention beats post-emergent control. Because doveweed germinates late and in waves and resists sprays, chasing established plants is the hard way. The people who beat doveweed are the ones who fix drainage and run a properly timed split pre-emergent program, so most of the weed never comes up.

Mowing and pulling can spread it. The creeping stems root wherever a joint touches moist soil, so chopping a wet patch with the mower or yanking plants apart scatters rooting fragments. Treat the patch, do not shred it.

There is no one-size product. The right chemical depends on your grass, and on bahia there may be no safe chemical answer at all. A blog that names a single product for everyone is setting someone up to damage their lawn. If you want the exact product and week for your specific zip code and grass type, that is what a personalized care plan is for, and you can start with a free photo diagnosis.

Your Doveweed Action Plan

1. Confirm the ID. Check for thick, smooth, lance-shaped leaves and fleshy creeping stems in the wettest part of the lawn. If unsure, get a free diagnosis from a photo before buying anything.
2. Fix the water. Switch to deep, infrequent irrigation and correct soggy spots, low areas, and drainage problems. This weakens doveweed more than any spray.
3. Strengthen the turf. Mow a notch higher, aerate compaction, and keep the stand dense so doveweed has no open, sunny ground.
4. Prevent next year. Run a split pre-emergent program timed to soil temperature, since a single early application wears off before doveweed germinates.
5. Treat by grass type. Match the post-emergent to your turfgrass, confirm the label lists your grass, and respect temperature and atrazine limits. On bahia, rely on cultural control.
6. Repeat and be patient. Expect several treatments a few weeks apart and a two to three year program on a heavy stand, since the seed survives in the soil for years. Keep the soil drier so the problem does not return.
