how does this herbicide work once it gets on the weed

Technically I do not know - It works really well as long as you mix according to the instructions - Killed all the weeds and did not touch the lawn. I waited three weeks and then used it again to kill what came up since the first treatment. I typically will use it now as the only plants growing inn the lawn right now are the weeds.

We actually bought three products from Amazon and combined them according to online recommendations. We have no creeping charlie at all for the first time ever! Together the products worked perfectly.

Well directions say it has to happen during germination ... Which I assume to be spring. I'd test it on a small area and see the results. It did not seem to kill crabgrass on the spot. Kind of seemed to help the other parts of my lawn from the crabgrass invasion so to speak.

Did you use it full strength? Sun or shade is a non-factor. The acid works by burning the foliage but does not necessarily kill the entire plant like an actual herbicide does. It will kill a very young tender plant, but probably not a hardy established one, and especially not if the plant has a moderately thick or woody stem.

It is a physical killer and will only kill what it touches, so it will not kill weeds before they come up.

First you have to wait for it to take effect. (kill the bad area) Then the area needs to be prepared. If it's a small area, it's simple, if it's a whole lawn, it's not so much. And the area of the country you live in will determine timing of things. It's not something that can be answered favorably without more information. I would suggest to contact your local state agriculture extension agency. They are experts in what works in your area. I've followed their advice for years and have excellent results. (I'm in Tennessee) It's a bit of work, but certainly worth it.

It takes a while to take effect. I have battled weeds for years in a gravel drive in a self storage. I always sprayed but this works better for me. I just walk through an apply to weeds and grass. I normally cannot keep up spraying but I have applied this twice.

I am not a lawn professional, just a home owner. I usually use this product to spot spray the weeds, not the complete lawn. In those cases the product is concentrated on the weeds. I usually wait two days, and it works very good for me.

I would suggest that you read application schedule on the weed and feed you applied ! The Bayer product has application rates and frequency of application suggestions on Label ! No weed killers work immediately, most take several days or more before you start to see results ! Read the instructions before using any Herbicide, Insecticide, or Pesticide and apply as directed !

I would wait at least 2 wks once it yellows and wilts to the ground to allow the herbicide to fully permeate the root system and kill the nutlets. I sprayed it twice one day apart to insure it got a lethal dose. Be sure to apply it when the plants are growing vigorously.................TJ

Don't make the solution any stronger than called for. The grass will get brown, but should come back. When spraying put on stream so you can get to the root. Don't just spray up in the air, such as lifting up the wand and higher than I or 2 inches from grass.

Depends on temperature and what your target weeds are. Read the fold out on the container. It's pretty explicit. but, don't expect this stuff to work. It used to be a wonderful product but something, I suspect the EPA, happened to it.

Seven days after application. No reason to wait until everything is completely brown. Glyphosate works faster in warm weather but it does kill what it is sprayed on in cool weather if the plant is green and growing.

You need a hose end sprayer with a dial on top. Fill bottle with product, attach, set dial at 2.50. Do not add water to mix let sprayer do work. Start at far end of yard work your way out with an even motion.Don't spray too early.let the weed warm up so the product enters If you have to spray in temps over 80 degrees set dial a little lower maybe at 2 knowing you will need a second application later in season good luck it is a great product

You can spray the whole yard but I applied it to the weeds I wanted to kill. It may take a couple applications too so you don't want to spray it where it's not needed.

depending on the size of the weed it can take a good week. I have never used a weed killer as good as this one .... it's worth the cost. I waited about 3 weeks before I planted anything

It depends. If it's hot out, 5 parts water to 1 part weedkiller works. If its cooler (less than 80F?) you need to make it stronger, maybe 3 to 1.

Yes it will kill everything, follow instructions, if you increase the concentration you can actually watch the grass die as you spray ityou should follow up with spot spraying in 5 to 7 days
