If we use this adjacent to the grass will it kill the grass? TIA

My patio is adjacent to a grassed area but I was careful not to let the solution run off onto the grass. I didn't want to take any chances and the grass is okay a week later.

Will this damage artificial grass that is next to my patio?

Hi, yes be careful to cover up plastic grass as I found it can turn the edges brown if the product gets orcruns on it. I used an old sheet to cover the grass area where the spay was going. Hope this helps!

Do you need to dilute this with water ?

It’s ready to use. I used it straight from the tub on the patio, but diluted it for use on the decking. Not sure if it’s suitable for decking but it came up great.
