Q.How To Get Rid Of Passion Flower
Greetings, I’m hoping you can help me–I planted a passion flower vine last year that became so overgrown that I pulled it out. Unfortunately, I hadn’t realized that it’s a terribly invasive plant and so probably did not take out the taproot since I have seen suckers sprouting everywhere this year that I have tried to control by digging out whenever they appear. I discovered one that took hold against the concrete foundation wall under our outdoor deck. Will this compromise the foundation if not eradicated? What is the best way to permanently get rid of this pesky plant? I read that glyphosate might help. Someone told me that bleach would work. I am at my wits’ end now, and I fear I might be pulling out shoots for a long time. Will these never end? Many thanks!

If your passion flower produced fruit that was left on the vine, it is also reproducing by seed. I have found the vines pull up easily, but as you say, there could be bits left behind to regrow. You can spray with glyphosate, 2,4D and others as noted in this article. Read and follow all instructions exactly.
