## 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
