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.
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 is applied to the foliage of the nutsedge or other labeled weeds you are targeting.
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.
Yes, SedgeHammer Herbicide is best applied outside of higher temperatures. You can apply in the morning if the daytime highs will be above that.
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.
SedgeHammer Herbicide will work in a succulent bed, but you would want to be careful not to let the product touch any of the plants, so you would only need to do spot treatments. The product may do damage to the succulents if it were to get on them.
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.
SedgeHammer Herbicide can be applied 4 weeks after seeding.
SedgeHammer Herbicide would not be recommended to be mixed with other herbicides.
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
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.
We recommend that you apply quinclorac separately from the small Sedgehammer packets since the Sedgehammer packet already contains a surfactant. Since quinclorac products generally require a more aggressive methylated seed oil surfactant, mixing these would cause extra stress on your desirable grass and may be too harsh.
