Your desirable turfgrass is likely under a lot of extra stress due to the summer heat right now, so it would be better to wait the 2 weeks for the Tenacity application to work before applying another herbicide for the same target weeds. Sedgehammer will take about 2-4 weeks to show results on nutsedge, too, so you will need to be a little patient when treating for this weed.
SedgeHammer could contaminate water. It is not recommended to be used in or around bodies of water. According to the product label, do not apply directly to water, to areas where surface water is present or to intertidal areas below the mean high water mark.
No, per the product label, SedgeHammer Herbicide can only be used around established woody ornamentals.
SedgeHammer Herbicide can be applied 4 weeks after seeding.
Yes, SedgeHammer + Herbicide can be used on a centipede lawn safely as directed on the product label.
You will want to mow 3-4 times before applying SedgeHammer Plus Herbicide.
Depending on how established the nutsedge is, it can take multiple applications to kill the actual nutlets, even when using an effective product like SedgeHammer + Herbicide. Ideally, the nutsege that will emerge in the upcoming growing season will be easier to control, because of the treatments you have applied in the last 12 months. Sometimes, it can take multiple growing seasons to eradicate a well established series of weeds from an area, even using the most effective of product.
Please view our Nutsedge Treatmet Guide for more information.
SedgeHammer Plus Herbicide should not injure turfgrasses as long as the lawn is established and sufficient water volume of atleast 1 gallon of water was used to apply 13.5g evenly over a 1000 sq ft area. Applications should be avoided during the heat of the day (65-85 degrees) and recommended to be done in the early morning or late afternoon/evening when temps are at their coolest.
If the turfgrass is under stress from heat, drought, diseases, insects, etc – these are all factors that can cause herbicides to injure turfgrasses.
Please view the full product label for more information.
Sedgehammer Herbicide is safe for use around established ornamentals, such as ornamental strawberries.
SedgeHammer Herbicide 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.
You can plant new perennials/annuals at least 4-6 week after SedgeHammer Herbicide application
SedgeHammer Herbicide would not have harmed the fig tree if used as directed. While it is not labeled to be applied around edibles and applications should be kept outside of the dripline of edible trees, unless you sprayed the tree directly it should not have been affected. There are many possible factors which could be affecting the tree. We would recommend that you contact your local cooperative extension office for advice on what may be causing this appearance and how to best treat it.
According to the SedgeHammer Herbicide label: Allow the turf to develop a good root system and uniform stand before application.
We do not recommend Sedgehammer for crabgrass control as it is only labeled for eradication of yellow and purple nutsedge and kyllinga. You can spot treat carefully with a non-selective post emergent control around Natal Plum and Sweet Pea etc. Sedgehammer is for lawn applications as directed.
SedgeHammer Herbicide is only sold/packaged individually.
