I bought some RoundUp concentrate today to make 5 gallons. What's the most effective way to use this stuff? Use it when its hot and sunny?
The RoundUp spray gun with the 1 gallon jug costs more than this? Why would people buy one over the other?
About all you need - weather wise - is to NOT have it rain on the weeds you sprayed until at least several hours after you spray. Preferably a day, but sometimes you're not that lucky.
RoundUp now sells their stuff in every conceivable concoction. You can get the premixed stuff in a simple spray bottle, pick it up and start spraying weeds. You can get the same premix in a bigger bottle with a separate spray head.
You can also get concentrate, super concentrate, ultra concentrate, and (probably) Ninja Kick The Balls Off The Weeds Concentrate. That stuff has to be mixed with water, and you use your own sprayer.
I have always gotten the "regular" concentrate. It's much cheaper than the premixed stuff, and I can always go back and re-spray the same weeds a day or two later.
