When is the Earliest that Glyphosate can be Applied to Hardscaping?

Hello all

I Hope you are Well.

I have just had a Walk around the Back Garden to see what I am in for once Spring comes around and I have noticed a few areas of the Patio, and Paving, where Grass is Growing between the Tiles.

The Grass seems to be actively Growing, so, when is the Earliest that Glyphosate can be Applied?

Thanks in advance

Kevin

 

Hello Kevin, if the weeds are actively growing then they'll be able to absorb the chemical and it will do it's work. The main constraint is weather. It needs to be done during a dry spell with little or no wind, to prevent drift onto nearby plants.

 

Hello @noisette47

Thanks for the Reply.

So Temperature is not a concern?

It will be a relatively Dry Day here Today and the Patio and Paving have Dried so I may go out now and Apply it, if it Works, Great, if not I will just wait and Apply it again.

Thanks

Kevin

 

The grass will be growing more slowly in cold weather, and it might stop growing if it turns cold again, so it might take longer for the glyphosate to do its job than it would in warmer weather. If it doesn't seem to be working, I would give it a month or six weeks at least before even thinking about reapplying.
