Topping Peppers: What does the science say, yay or nay? - Ep. 299
Episode 299
Tuesday, 5 May, 2026
The subject of whether you should top your pepper plants can bring on a pretty strong debate among gardeners. That’s because this is one of those topics where the answer genuinely is: it depends. And I mean that in a very specific, evidence-based way that comes down to two things: your climate and your pepper type. I’ll be straight with you, I do not top my peppers. We are in a zone 6b in west central Missouri and our season is just short enough that for our large sweet peppers, by the time a topped plant recovered and loaded up with new fruit, I’d be in a race with the first frost, so I don’t love my odds of winning. And for our smaller peppers, both hot and sweet, they branch naturally. They’ve never needed my help getting bushy and they generally end up so loaded with fruit there’s no need for me to create new growing points. But that does NOT mean topping is wrong. In fact, if your growing season is long enough and you are growing the right type of pepper, there is a solid, research-grounded argument for it and I want to make that argument fairly today.
