Oh, they’ll come back on their own—no intervention needed.
The more you ignore them, the stronger they get.
I’ve been battling them for 4 years now. They live under my deck and come out to strangle my azaleas.
It’s quite simple: just pull them out in the fall. I’ve been doing this around my front porch for 30 years. It only takes about an hour before they go to seed, and you just need to pull up a few as they appear. It’s not difficult at all.
The harder you try to get rid of them, the more stubborn they become.
For a moment, I misread “Winterize” as “Weaponize” and got really excited about the potential responses!
Thanks, now I can’t stop picturing roving columns of morning glories taking over in an apocalyptic scenario.
I suppose you could weaponize the seeds since they contain LSA, which is similar to LSD.
