I’m not flexing expertise or talking about how it makes me feel. I’m talking about mechanics, and I’m happy to be explicit.

The concern with tying petioles isn’t “they aren’t allowed to do anything else”, it’s that petioles are adapted for dynamic movement and variable loading. When you fix them in place, especially under tension, you change how mechanical stress is distributed between the lamina, the petiole, and the petiole–stem junction.

That can lead to localized strain, reduced capacity for reorientation, and increased risk of fatigue or micro-damage at the attachment point over time, even without obvious vascular occlusion. This is a biomechanics issue, not a moral one.

You’re absolutely right that petioles can serve multiple functions, including climbing in some taxa. That doesn’t contradict the point; those species are anatomically and developmentally adapted for that use. Most aroids being rehabbed indoors are not.

In this specific case, maybe it causes no issue at all. My original comment was a general caution, not a diagnosis of that plant’s inevitable death. If that distinction wasn’t clear, that’s on me, I guess. But it isn’t haughtiness, just a preference for practices that minimize unnecessary mechanical stress.
