  • Asked by Nick from San Gabriel,california
    08/21/2014
    Q
    After applying SedgeHammer to some nut grass in planter area, how long do have to wait to put in azalea plant?
    I want to put azalea plants in area where nut grass is located.
    A
    Per the manufacturer, you would need to wait a few months in order to plant the azaleas as you will have to do multiple treatments of SedgeHammer. When you do plant them, make sure you are not using the soil that was treated with SedgeHammer. Use either topsoil or untreated soil from another area on the property. They did also recommend that you plant the plant first, get the roots established and then use the SedgeHammer. Do not spray direct on the azaleas to avoid damage. Please let us know if you have any additional questions.

    Yes, you can apply sedge hammer herbicide to your bermuda lawn before the temperature reaches 85 degrees.  Apply with enough time to make sure it’s dry before the temperature reaches that point or apply in the evening after temps have cooled off.

  • Asked by Alma from El Paso, Tx

    Q
    Is it safe to use Sedgehammer directly around the base of established trees in the lawn?
    I have a lawn that is almost completely nutgrass. I have mature mulberry and ash tress in the lawn as well. I don't want to kill my trees but the nutgrass has completely taken over. Is it safe to spray Sedgehammer directly over the lawn that covers the roots of my trees? Thank you for such an informative website!!!
    A
    Sedgehammer may be applied to nutsedge that is at the base of a tree without harming the tree as long as you do not spray over top the tree as a broadcast. Try to be careful of overspray that may get on the tree as the label states that sprays directed over-the-top of trees may lead to damage of the tree.

    Q
    Is it safe to use SedgeHammer Herbicide on an established bed of Liriope?
    A

    SedgeHammer Herbicide should not be applied around groundcovers, ornamentals, vegetables, shrubs, trees, or flowers. It is to be applied to turf areas only. You can look at using a product like Image Kills Nutsedge Concentrate as it is labeled to be applied to Liriope.

  • Asked by Cindy from Scottsdale, Az
    08/24/2014
    Q
    Will Sedgehammer harm our fruit trees
    Grapefruit, orange and Lemmon
    A
    The Sedgehammer herbicide kills nutsedge without injury to turfgrass, established ornamentals, shrubs, and/or trees. 

    Certain products are not labeled for use around edibles as it could cause harm to the plant either through absorbing it into the food you are going to eat, or by killing the plant. Unless it has an agricultural label you can not use it around edibles or near the drip line. If you want more details on how using SedgeHammer to close to edibles can affect them, you can contact the manufacturer Gowan at (800) 883-1844.

    Q
    If you spray SedgeHammer in the fall, will it keep nutgrass from coming back the next year?
    A

    SedgeHammer is a post-emergent herbicide, so it will work on actively growing nutgrass, but will not prevent future growth.  Pennant Magnum and Echelon 4SC would be pre-emergent options for nutgrass.

  • Asked by Jose from Miami, Fl
    03/14/2016
    Q
    What can I use to control and kill Nutsedge and creeping signal grass on St Augustine grass?
    Miami Fl area
    A

    For nutsedge control it is best treated using something like Sedgehammer Herbicide which is specifically designed for it and is also for some other broadleaf weeds.  For signal grass is it best treated with a pre-emergent like Prodiamine 65 WDG but complete control is not always possible with this weed as it is a very difficult weed to control.  You could also spot treat with a glyphosate based product like GlyPhoSel Pro and then reseed/so the area.  The University of Florida has some information here about.

  • Asked by Clint from Rosedale, Ny
    08/14/2017
    Q
    Do I have to pull up weeds after applying Sedgehammer?
    A

    No, you do not have to pull the weeds after applying SedgeHammer Herbicide, however, continually removing shoots eventually depletes the energy source reserves in the tubers.  Tubers are key to nutsedge survival. If you can limit production of tubers, you’ll eventually control the nutsedge itself.

  • Asked by Josh from Woodbury, Mn
    09/17/2017
    Q
    How late in the season can Sedgehammer be applied?
    I have a nutsedge problem in my yard in Minnesota and just overseeded at the beginning of September. Is October too late to apply Sedgehammer to a yard?
    A

    Sedgehammer will only control weeds that are actively growing, so it likely will not kill anyting in the winter once the plants are dormant, and it may only give partial control in the fall. It is best used in the warmer spring and summer months and early fall.
