Japanese knotweed seems who just laugh off roundup. Is there anything that will kill this? We have this in a no-man's strip between a neighbor and I. It is hard to access the area.
Always looking for interesting plants for pollinators and food! Bonus points for highly, and pleasantly scented plants.

I have had an ongoing fight against Japanese knotweed ever since my neighbor planted some as a screen. My best advice is to use Groundclear. It will most likely take several applications but it is the only thing I've found to knock it back significantly. You won't be able to plant anything there for at least a year after the last application but it sounds like that won't be an issue for you. Good luck!
