When should I apply SedgeHammer?
For optimum results it is best to apply SedgeHammer to young, actively growing nutsedge plants (plants that have emerged within the last 6 weeks). SedgeHammer works by killing the foliage and underground tubers. However, nutsedge plants that survive longer than 6 weeks can produce new nutlets. There may also be nutsedge that has emerged and sprouted above ground since the time of your application. SedgeHammer applications must be made consistently to ensure eventual eradication. Read the label for specific directions regarding maximum number of applications and rates.
How long does it take SedgeHammer to work?
Sedgehammer is absorbed into the leaf tissue within 24-48 hours and enters the vascular system. It travels to the base of the leaves where the growing point is located. Critical amino acid production within the plant is then halted. Yellowing and browning of leaves usually occurs within 10-14 days. It may take an additional 2 weeks before the nutsedge dies. If the nutsedge is not actively growing or is stressed in any way, this process may be delayed or interrupted.
How often do I need to use SedgeHammer?
Sedgehammer often works with one application, but depending on the size and age of the nutsedge, multiple treatments may be needed (always read and follow label directions).
What is the shelf-life of SedgeHammer?
Left intact in the original package, SedgeHammer kept in a cool, dry place can be stored for a few years without detrimental effects. Always use SedgeHammer the same day it is blended. SedgeHammer begins to degrade once it is mixed in water.
Does SedgeHammer need to be watered in?
No, for application on emerged and actively growing nutsedge, watering is not required. It is important that the SedgeHammer mixture completely cover the nutsedge until it glistens.
Is SedgeHammer safe to use on my grass?
Sedgehammer is one of the most “gentle- to- turf” products around. It has proven to be safe to most commonly used grasses of North America and has been successfully used for many years. Many other products are safe to only warm season or certain kinds of turfgrass. Turf should be well established with a good root system prior to application.
Can SedgeHammer be used in my vegetable garden?
No, SedgeHammer can not be used in vegetable gardens or in or around annual plant beds. It can be used in landscapes around established woody ornamentals as a directed spray on the sedge. Avoid contact of SedgeHammer with the leaves or plant parts of desirable plants.
How long to I need to wait before tranplanting into a treated area?
The woody ornamental should be transplanted at least 3 months prior to an application. Avoid contact of SedgeHammer with the leaves or plant parts of desirable plants.
Can I use SedgeHammer on a new lawn?
It is recommended that the grass be allowed to establish a good root system prior to applying SedgeHammer. If overseeding, wait a minimum of two weeks before applying. If sodding or reseeding allow at least 4 weeks before an application.
How soon can I mow my lawn after application?
For best results, do not mow for two days before or two days after spraying SedgeHammer.
How soon can I water after application?
SedgeHammer is rainfast within 4 hours of spraying. Wait 4 hours after application before watering your lawn.
How soon can I resume normal use of the treated area, including allowing pets on it?
It is best to stay off the turf until the spray droplets are dry.
What other weeds will SedgeHammer control?
SedgeHammer will also suppress horsetail (Equisetum arvense) and kyllinga.
