Sedgehammer is meant more for nutsedge control in turf grass and it cannot be used near a vegetable garden or anything edible. For nutsedge in landscaped areas it is recommended to spot treat the sedge with a glyphosate or Round Up type product directly. We recommend Roundup QuickPro 1.5 oz. packs for ease of use
Sedgehammer Herbicide is applied to the foliage of the nutsedge or other labeled weeds you are targeting.
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.
Sedgehammer Herbicide should not be used over any desirable ornamental plants, including roses. You could spot treat with a product like Roundup in the area.
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.
SedgeHammer Herbicide would not be recommended to be mixed with other herbicides.
You can use a spray indicator when applying herbicides like SedgeHammer Herbicide. We would recommend using a product that is specifically made for this use to ensure that it does not interfere with the efficacy of the herbicide. You can browse our Spray Indicators here.
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.
It is safe for pets to be in areas treated with SedgeHammer Herbicide after the treated areas have completely dried, which is usually about 4 hours after application.
There should not be any issues using Tenacity Herbicide and Sedgehammer Herbicide at the same time as long as the turf is established and not under other significant stress. Tenacity Herbicide states the following in reference to tank mixing. We always recommend doing a small tank mix test before application.
Per the manufacturer, you may need to wait a few months in order to plant as you may need to do multiple treatments of SedgeHammer Herbicide. If you do make multiple treatments, you can plant new perennials and annuals at least 4-6 weeks after your last application.
SedgeHammer Herbicide is labled to control only the broadleaf weeds listed on the label. However, since flowers are considered a broadleaf plant species as well, you would want to not spray over the top of the desireable plants. Try to limit sprays to only the weeds you wish to eliminate and be cautious of any drift of the product to nearby flowers.
