Does round up work on moss on tarmac?

[fitzykev]

I was out doing the garden and put round up down as the weeds along the edge of the house are just crazy. Part of the path is tarmac and is covered in thick moss which I sprayed with round up. Will it do the job?

Should do

It will.....but it’ll be back again!

No, glyphosate doesn't kill moss

It doesn't kill my moss.

I have heard biological washing powder does. Have you heard this?

 

[scbk]

Yes, or soda crystals, about a £ a bag in tesco

Happy days thanks

I use warm water with a handful of salt dissolved in a bucket, a yard brush and vigorous action to keep it down. Moss is very difficult to kill.
I don't mind having it on the drive but have to do something about it on the yard when it builds up and becomes slippery.

"Wet and Forget" will treat it.

There are other products but I don't remember the name.

I had never heard of Wet & Forget until John mentioned it. What I have used it is Patio Magic, it (and Wet & Forget, probably others) are c. 7-8% benzalkonium chloride that you dilute down to 1-2% and apply by spray / watering can.

Once the moss is dead, it will turn brown & shrink but will still be there. And it will come back!

I'm not an expert but I would be very surprised if glyphosate worked. It is designed to kill quite different types of plants.
