First, a crucial warning: do not just yank at the pretty green leaves. I learned this the hard way, like a cartoon character who thinks they can pull a tablecloth without breaking the dishes. Ivy’s roots are like superglue dipped in concrete. If you pull the top, you’ll just snap the stem, and the root will laugh at you.
That little jerk will then regrow, stronger than ever, just to spite you. You need to get personal with its dirty laundry.
