Note : This information is base on experience in the Mid - Atlantic commonwealth ; good word in other area may vary .
Broadleaf dock and curly dock are introduced perennials with strike tooth root that grow all over North America and are common in the Mid - Atlantic region . Seedlings come up all year , but the most add up up in the spring and twilight , when daily temperature changes are the biggest . fall down emerge seedlings will winter and resume development in the outflow . plant can grow back from the taproot as soon as five to eight workweek after they sprout , but they can only produce back from the rhizome for two to three years . Both species are very resistant of frost .
Dock weed , also known as broadleaf bob or curly loading dock , is a persistent and invasive weed that can quickly take over gardens , lawns , and flowerbeds . With its foresighted taproot and ability to regrow from the smallest base fragments pass on behind , dock weed can be notoriously difficult to control . However , with some perseverance and the right techniques , you may get disembarrass of dock sens for good .
What Makes Dock Weed Hard to Eliminate
There are a few key characteristics of dock weed that enable it to spread readily and evade removal attempt
Taproot – Dock grass has a long taproot that can extend several feet hush-hush , take manual removal difficult .
Regenerates easily – Even small sections of dock weed ’s taproot left in the ground can resprout into new plants
ego - seeding – Dock mourning band make 1000 of seeds that dissipate and sprout Modern weeds
Tolerates mow / press clipping – Removing top maturation does little to stop dock weed as it just regrows from the intact roots .
produce sharply – In ideal condition , dock weed can pass on up to 5 understructure tall , shading and crowd out desirable plant life .
Organic Ways to Remove Dock Weed
For gardeners who want to debar chemical herbicide , here are some constitutional options to try :
deal prod roots – apply a shovel or trowel to dig at least 3 inches down and take away as much of the taproot as potential .
strangle with mulch – covering patches with 3 - 4 inches of mulch to hinder sunlight and prevent ontogeny .
solarise the soil – Cover the area with light plastic in summertime to “ bake ” weed seeds and roots .
Apply Zea mays gluten meal – Works as an constituent pre - emergent herbicide to inhibit seed sprouting .
assert healthy turf – A thick , vigorous lawn will serve crowd together out sorrel weed seedling .
Stay on top of removal – Do n’t give up plants to go to seeded player and continually remove newfangled sprout .
Chemical Herbicides for Controlling Dock Weed
When organic options fail , certain chemical herbicides can be in force against dock green goddess :
Glyphosate ( Roundup ) – Systemic weed killer that kills the integral plant when apply to leaves .
Triclopyr ( Turflon ) – Selective broadleaf locoweed killer safe for grass that will shoot down dock Mary Jane .
2,4 - D – Kills broadleaf skunk like bobtail but not grass . May require repetition applications .
Pre - emergents ( Pendulum , Barricade ) – make a chemical substance barrier to prevent wharf weed seed from shoot .
acetum – eminent concentrations ( 20 % acetic acid ) provide non - selective Mary Jane mastery .
Always translate weedkiller label carefully and take safety precautions when using chemicals .
Timing of Dock Weed Removal
Spring – Hand dig first flush of young plants when filth is moist and roots are short .
summertime – As plant make maturity date , mow or enforce systemic weed killer for best translocation to the roots .
Fall – Spot do by any last remnants before plants go hibernating for winter .
Late descent – hold pre - emerging herbicide to suppress next year ’s seedlings .
Control and Prevention Tips
Eliminate germ product by cut or mowing plants before they flower .
Do not rototill or train areas with dock weed as this spread the roots .
After herbicide treatment , replant with native plants beseem to the environment .
uphold healthy soil and avoid compacting root word zones where dock weed flourishes .
Buy weed - free seed intermixture and mulch to fend off introducing dock gage .
supervise on a regular basis for novel seedlings and remove immediately before roots instal .
How to Recognize Dock Weed
identify dock smoke is the first step in insure it on your property . Here ’s how to recognize it :
grow as a basal rosette in the first year with large ellipse exit up to 6 inch long .
Mature plant can reach 5 feet magniloquent with reddish , carinated stem .
Leaves are alternate , fizgig - shaped , with curly or crinkled margins . Often have red vein .
Tiny dark-green flowers prime on branched stubble in summertime , bring forth hard browned seeds .
Forms dense stand and populations from an extended underground root system .
Most often found in moist domain like stream Sir Joseph Banks , ditch , meadows and worried sites .
Persistence is Key
While dock weed may seem impossible to get rid of at first , do n’t get discouraged . It can take persistence over multiple mature seasons to fully eradicate . Use a multi - fork-like approach compound manual remotion , maintenance of healthy sward or landscape plants , and smart app of constituent and chemical controls . With vigilance to identify and snipe each unexampled generation of ejaculate and sprouts , you may rid your yard of dock weed for good .
How important are herbicide rotation and tank-mixing?
farming professionals often say that to delay resistance , it ’s best to flip between herbicide MOA and utilise two or more good MOA in tank car mix . When used together , the chance that a weed will become resistant to two different herbicide MOA is lower than the chance that it will become resistant to just one herbicide MOA . Also , changing the MOA during and between seasons glower the amount of time the flora are exposed to the combat-ready element and the selection pressing it might put on them . In the next example ( Table 1 ) , two good MOA are used to do by only Palmer amaranth , one of the three weeds that are being place .
Table 1 . Introduction to multiple in force modes of action .
Multiple in force MOA can help manage weeds and delay weedkiller resistance , but only if there are n’t any biotypes of weed that are already repellent to weedkiller from sure groups . As an instance , Table 2 render that several effective weedkiller MOA can be used to get rid of waterhemp that is n’t tolerant . However , as multiple resistance becomes more problematic , good herbicide mode of military action become circumscribed . Without resistance , there are weed killer from seven style of natural action groups that can direct waterhemp . However , if you see six - way resistant waterhemp which has been identified in at least two U. S. states , only glufosinate ( Group 10 ) stay to help moderate the six - way of life - resistant biotype . Some of our most troublesome weeds already have multiple resistance , which make it much hard for us to use herbicide selection strategies that work for managing resistance .
Table 2 . Effectiveness of seven different MOA groups for control of herbicide - susceptible and herbicide - repellent waterhemp in corn or soy . Waterhemp ranges from susceptible to have six - direction herbicide resistance . In Missouri , Minnesota , and Illinois , waterhemp has been found to be resistant in six dissimilar ways . In Ontario , Canada , and North Carolina , it has been found to be resistant in five different direction .
New research on rotating vs. army tank - mixing herbicide has shed young light on which method is good for contain weedkiller electrical resistance , including ohmic resistance at the target area situation and resistance at other site . For an overview of this , watch this GROW video with University of Illinois weed scientist Dr. Patrick Tranel :

What does it cost to manage herbicide resistance?
It ’s not probable that herbicide - resistant biotypes will vary back to susceptible biotypes within a farming propagation , even if you break using the herbicides that they are resistant to . This is especially true if the resistant biotype becomes ground for several years and is produce source per annum . Once opposition is determine up , fields usually have a mix of biotype that are susceptible and biotypes that are resistant . We ’ll call these biotypes S and R. The ratio of these individuals could change over time bet on weedkiller use . Over clock time , using the same mathematical group of herbicides over and over will make the universe of a biotype that is insubordinate develop and become the dominant biotype .
There is a phenomenon in plants be intimate as a “ fitness penalty , ” wherein the resistor trait come with deficient maturation and/or breeding . But in most instances , herbicide resistance does not appear to enclose a material seaworthiness penalty . As a issue , even if the problem herbicide group is no longer used , and a portion of the susceptible seedbank continue , the population will likely retain to be a mixture of R and S biotypes . Depending on the mintage and other direction input signal , weed source can persist in the soil for several eld . Seeds buried deeperin the plow layer incline to remain executable longer than seeds nearer to the soil surface . Of course , seeds bury below the depth they are capable of egress pose fiddling endangerment , unless they are bestow back near the dirt surface with tillage . The seed of some mintage , such as gargantuan foxtail grass and other annual skunk , generally survive for only a few years . Others with harder seed coat , such as uncouth lambsquarters and butter-print , might survive for decades in the stain under the right consideration . bet on the grass species , this could impact the longevity of both R and S biotype seeds in the soil . If there are no weed seeds grow at the ending of the growing time of year , the sizing of the Mary Jane seed camber will decline as source die , and the frequency of R and S biotypes should stay the same .
