The RU I used came in a one gallon(?) jug that's white with a yellow/gold label and spray nozzle. Says *Poison Ivy and Brush killer*.
I didn't read through the whole label - that could take forever and a jeweler's loupe - but I didn't see anything about being able to plant again in 2 weeks. I think this may be strong than that.
But I only sprayed the leaves and nothing on the ground around the plants died. My gardens are elbow to elbow plants. I just shot at the leaves I could hit and it still killed off what I wanted.
Except the mint bed. I mass sprayed the ivy and elephant ears 2-3 times (I mean I hosed that stuff) so far, and they're about dead. The mint is growing back over the dead stuff though. Mint is like that.
I'm like you, never did poison, just manually weeded. I am just too busy to do it this year and the place needs to be decent - I'm gonna sell it. So far so good.
Good luck.
