Review: Very satisfied with the spray effectiveness. It took about 5 days to see good results. The sprayed area kept looking more brown indicating that it keeps on working. I sprayed this with a garden sprayer and my helper used an electric spray wand. I mixed it as 3 Tbl spoons per gallon to ensure it was non-selective. It was very easy to mix as hi-yield includes surfactant pre-mixed. I started with water and then added the herbicide. It was fast spraying. I had also tried concentrated vinegar at first, but realized I needed something that also got to roots and nodules. The kill speed using herbicide is as expected. It has been several. I recommend wearing gloves when handling this concentrate as well as during spraying. This is quality herbicide concentrate. It has been weeks after the spray and there is no fresh growth in the sprayed areas. I still have plenty herbicide concentrate for the next season. This was a good purchase.
Review: Great all around grass and weed killer. Use it to treat the perimeter of my fence and it works in a day or two.

## Questions & Answers

**Q: will this still work if weeds are already cut to the ground?**
A: Like all glyphosate products, the spray is put on the leaves and is taken up by the plant.  It is translocated thru the plant and kills it.   Less foliar area means less surface to absorb the herbicide.   So you should expect less effectivness if the weeds are cut to the ground.   Why bother cutting them, if you are going to poison?  After application of glyphosate you will not see any effects for about 14 days.  Works best in warm weather (active weed growth).  good luck.

**Q: WILL THIS PRODUCT KILL JOHNSON GRASS**
A: 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.

**Q: Waiting period to replant grass sod ?**
A: KillzAll only has a residual of about 2 weeks on the soil so you just have to wait 2 weeks before reseeding/sodding

**Q: how long before pets can go out after it is sprayed?**
A: when dry so does not stick to paws. No licking

I bought this to kill stubborn weeds in my gravel driveway after trying all season with other products. I didn't diluted it as instructed. I had it stronger and mixed with vinegar instead of water. That killed my weeds!
