How long does it take for it to kill the nutgrass after spraying?

It takes about a week, maybe a little more, to see it begin to work. Within 2 weeks the nutsedge is obviously dead or close to dead. This stuff works great on this weed that I can't otherwise kill. There isn't much I can us on my floratam (version of St Augustine) grass. Sedgehammer (which goes by a couple other names as well) finishes what the atrazine doesn't touch. Be prepared to spray a few times though because the first pass will miss some. It only kills the sedgeweed that is actively growing.

Almost immediately...it will . stunt growth and will turn yellow within 2-7 days. If you truly have nursed he, this will . absolutely work...I was so pleased with this product....bc it out grows the lawn and made it look unkempt even 1 day after mowing. As you know this stuff grows fast....and you will notice that it won't grow even before it turns yellow.

The grass started turning yellow within 10 days. I then mowed and it was gone. Dave

In about two days the Nutsedge blades all turned yellow. A week later I mowed the lawn including the nutsedge blades. The Nutsedge did not grow back. It has now been at least a month and there is no sign of regrowth.

Like any insect; you have to follow their cycle. The first spray should be followed by several more, at least once a week up to four weeks depending on your infestation. If in your lawn you can sight grub damage easily; the grass picks up like loose hair shaved off. Make sure you have a mix that includes grub control.

This product deals effectively with weeds and crabgrass without harming your lawn provided you follow dilution instructions. The first application will help ridding good percentage of the weeds, then you should follow with a second application 3-4 weeks away then as needed.

Takes about 1 1/2 months approximately. I really liked the results be sure and hose off your lawnmower off after each cut.hosing off any and all seeds that can stick to the underside of your lawnmower will help help also. Don't be discuraged it definitely works.

It will definitely kill the Bermuda grass, but I'm not sure about the irises. I know that it killed my calla lilies but did ok on the azaleas and my other trees.

It kills everything, even grass. I add 1/4 dishwashing liquid and 2 TBS salt. Apply with a sprayer when the sun is out and it's hot.

Most likely it's too late! This is a pre-emergent. It has no effect on crabgrass that is already growing, even though it states on the bag it will work for 4 weeks after germination... at least that was my experience. If you already see crabgrass in your lawn, you should find a post emergent product specifically formulated to kill crabgrass.

I do not know. I do know it will kill St. Augustine Grass here in Florida. It also controls torpedo grass in my junipers. I lift up the juniper runners and spray directly on the torpedo grass/ Sorry I could not be of more help.

I'm not sure what buckthorn is by that name, but I use 2 oz. per gallon and it kills everything I spray it on. Since the growing season is about over, I would spray it two days in a row and sit back and watch it die--takes about 2 weeks to see it withering up, but will die and disappear.

hello . the way this stuff works is all broad leaf plants have a tiny cup at the very bottom of the leaf cluster , water and nutrients puddle there and are absorbed by the plant . and a grass is a straight shoot no puddle there . so when you spray the active weed killer drips into the puddle , the plant drinks , and BAM dead weed or flower oops . this type of herbicide has a fairly short lifespan (normaly a 3 to 6 days depending on rain) whereas weedkiller like roundup is super sticky and has heavier molecules , so it sticks to everything and stays alot longer (depending on rain 4 to 8 weeks) so yes this will murder you flowers . and it's fun to be a farmer . hello . the way this stuff works is all broad leaf plants have a tiny cup at the very bottom of the leaf cluster , water and nutrients puddle there and are absorbed by the plant . and a grass is a straight shoot no puddle there . so when you spray the active weed killer drips into the puddle , the plant drinks , and BAM dead weed or flower oops . this type of herbicide has a fairly short lifespan (normaly a 3 to 6 days depending on rain) whereas weedkiller like roundup is super sticky and has heavier molecules , so it sticks to everything and stays alot longer (depending on rain 4 to 8... » Read More hello . the way this stuff works is all broad leaf plants have a tiny cup at the very bottom of the leaf cluster , water and nutrients puddle there and are absorbed by the plant . and a grass is a straight shoot no puddle there . so when you spray the active weed killer drips into the puddle , the plant drinks , and BAM dead weed or flower oops . this type of herbicide has a fairly short lifespan (normaly a 3 to 6 days depending on rain) whereas weedkiller like roundup is super sticky and has heavier molecules , so it sticks to everything and stays alot longer (depending on rain 4 to 8 weeks) so yes this will murder you flowers . and it's fun to be a farmer . « Show Less

have tried this 2x. did not kill entire yard, seeds took temporarily. the grass later died or diapeared & the weeds came back or a bald spot appeared. in other sections of yard had almost 1/2 yard cleared, all that hapened after temp.growth was the ST AUGUSTINE & BERMUDA pushed out new grass. my guess is that your yard has 2 be as bald as the MOON!

According to the label it works by going to the roots of the plant. It is only "active" for a short time. In most cases it would ideally dry and be drawn into the leaves and travel to the roots in a day or so and kill the plant. The label says "replanting" can take place then or within 3 days in most cases. In my experience you may have to reapply for full kill of "tougher" growths. So in my opinion you should schedule a few weeks for spraying in the warm spring and then can replant a few days after the last application. You may not notice the "results" for a few weeks and some grass (in my case mostly canary grass) was a little hard to kill and need a few applications, although generally re-applying is only necessary for "new" plants or old seeds.

If label includes centipede grass, it will take two or more sprays about 2 weeks apart to kill it. It is safe on broadleaf plants so probably is okay on this juniper.

One gallon is WAY more than enough for 1750 sq ft.... The concentrate dissolution is 3 tablespoons per gallon (1.5 oz per gallon) I put 3 gallons of water and 5 oz of Killzall in my 4 gallon backpack sprayer (3 gallons because I don't want to carry 24 pounds around at first as I spray....) Those 5 oz cover about 1/4 acre, the way I spray (a little over 10,000 square feet_ I spray my entire 3/4 acre grass area in February/March when the Bermuda is dormant.... killing everything green in about 3 weeks.... wilt starts in 3-4 days depending on temperature. Surrounded by pasture, I have a lot of noxious weeds and grasses that stay green in winter. Great product! One gallon is WAY more than enough for 1750 sq ft....

yes it will kill Johnson grass. Mix according to label (5 tablespoons per gallon) mix well, spray foliage surface, wait 10-14 DAYS, then it will be dead.
