My little bro lives in rented accomodation and the garden was horrendous. He cut it all down from waist height, but didn't dig the roots out. It is mainly brambles& sticky weed. Obviously he wouldn't listen to his big sister who told him to dig the roots out hehe. He then put a load of gravel down. Anyway obviously it is growing back and he was asking about using glyphosphate on the new growth. He has a dog. Would it be safe if he sprayed the ground and then kept the dog out of the garden for 2 days?
I would have thought so, providing the dog is not in the habit of chewing plants.
If you do it on the morning of a dry day all should be OK the following day!
It neutralises when it touches the soil so if it is a dog that likes to root around in the soil then again I would think things should be OK
