Sedgehammer is labeled to kill nutsedge without injury to listed established turfgrasses. You should not apply over-the-top of desirable ornamentals, shrubs, and/or trees. We are not sure how the product would effect prairie so we recommend calling the manufacturer who is the expert on their own product. The manufacturer is Gowan Company and they can be reached at (928) 783-8844.
Sedgehammer can be used in St Augustine grass per the product label but is not labeled for wandering jew and we do not have a product that is labeled for this weed. It might be best to spot treat this weed with a glyphosate based product and reseed the areas.
Sedgehammer Herbicide should be applied to established sod that has an established root system or until it can stand the application under these guidelines.
As long as SedgeHammer Herbicide is not restricted to your state, you can purchase and apply to your own property with a license.
Areas treated with SedgeHammer Herbicide may be overseeded with annual or perennial ryegrass or bermudagrass 2 weeks after application. Seed should be applied as directed on the seed packaging. Sedgehammer often works with one application, but depending on the size and age of the nutsedge a second treatment may be required 6 to 10 weeks after the initial treatment. You do not want to dig up the treated sedge as it will take time to completely kill and you may need to do another application.
SedgeHammer Herbicide can only be applied to established turf. It should not be applied to ornamental or landscaped areas or edible vegetation.
SedgeHammer Herbicide is labeled for eradicating Purple Nutsedge, Yellow Nutsedge, Kyllinga only.
SedgeHammer is a post-emergent herbicide to control nutsedge and listed broadleaf weeds. You will need to spray existing exposed plants for the active ingredient to be absorbed systemically down through the roots and nutlets of the plant. If used correctly on the lawn areas, then this product would not harm an above-ground pool in the area.

SedgeHammer Herbicide is not an organic weed killer. We carry Avenger Weed Killer Concentrate which is organic but it's also a non-selective weed killer.
