Last spring, a reader from the UK emailed me a photo that stopped me mid-coffee. It showed what looked like a fist-sized cluster of knobby stumps at the top of a mulberry trunk, all sprouting a wild, chaotic halo of whip-thin new shoots reaching in every direction. Her message was worried: Is my tree dying? Or did someone do this on purpose?
It was pollarding — done years ago and clearly maintained since — and I realized right then that I needed to write this post. Because yes, someone had done it on purpose, and it is genuinely one of the oldest tricks in the mulberry-growing book. But here’s the part that matters: it is almost certainly not the right choice for what you actually want to do with your tree.
I get some version of this question every single year. Usually from someone who inherited an old, oddly-shaped mulberry tree. Sometimes from someone who saw a pollarded street tree in Europe — those elegant, knobby-topped specimens you see along old parks and village greens — and decided they wanted that look at home. So let’s talk about what pollarding mulberry trees actually is, where it came from, why it works so well on mulberries, and most importantly: why most home fruit growers should think very carefully before trying it.
What Is Pollarding, Exactly?
Pollarding is a pruning method that sounds far more complicated than it is. Here’s the straightforward version: you cut a tree’s main branches back hard — really hard — to a consistent framework of permanent knuckles or stubs every single year or every other year. Those cut points are the same ones each time. Year after year, the tree responds by pushing dense, vigorous regrowth of new shoots from those exact same spots, creating a characteristic knobby, branching crown at the top of a permanent trunk.
It’s been done for centuries, particularly in Europe and Asia, and mulberries were one of the preferred trees for the job. But here’s the historically important bit: it wasn’t typically done to grow fruit. It was done to grow leaves. Specifically, soft, young leaves for silkworms. In the sericulture trade, pollarded mulberries were the leaf factory — consistent, predictable, fast-regenerating. The fruit was almost always secondary.
If you’re wondering how pollarding differs from coppicing (another term that gets thrown around), here’s the key difference: coppicing cuts the entire tree back to near ground level and lets it regrow from the roots, which is fast but delays fruiting significantly. Pollarding keeps a permanent trunk and maintains those knuckles at a consistent height, which matters for mulberries because it affects how quickly your tree can get back to producing berries after you’ve cut it hard.
Why Mulberries Tolerate Pollarding So Well
If you’ve read my complete guide to pruning mulberry trees, you already know that mulberries are unusually tolerant of hard cuts. They’re vigorous, fast-healing, and almost aggressively eager to push new growth. That’s actually why they became the tree of choice for pollarding in the first place.
A well-established pollarded mulberry can push several feet of new growth from each knuckle in a single season. I’m talking dense, healthy, enthusiastic regrowth. The tree doesn’t sulk. It doesn’t decline. It bounces back like you just gave it a pep talk and a strong coffee. This is genuinely impressive from a horticulture perspective, and it’s why the technique has survived so long on this particular species.
But — and this is a big but — that vigor comes with a condition. Pollarding must start while your tree is young. You establish your knuckle framework on 2–4 year old wood, and then you commit to maintaining it on a regular annual or biennial cycle forever. If you start pollarding on an old, never-pollarded tree, or if you stop partway through and then try to resume years later, you can trigger weakly attached regrowth or significant dieback. It’s a technique that demands consistency.
The Real Problem: Pollarding Sacrifices Your Harvest
This is where I need to be direct with you, because this is where most home growers make their decision.
If your goal is to eat mulberries — to fill bowls with sweet, dark fruit every summer — then pollarding mulberry trees is almost always a poor fit. When you cut those branches back hard year after year, you’re removing most or all of that season’s fruiting wood. The new shoots that regrow are energetic and leafy, but they’re less likely to set fruit that same year, or if they do, you’re trading quantity and quality for the sake of maintaining those knobbles at the top of your trunk.
This is why pollarding was traditionally used for sericulture and ornamental management — not for harvest-focused home orchards. If you want leaves for silkworms, or if you want a particular aesthetic look in your landscape, pollarding is brilliant. But if you want berries, it’s fighting against your own interests.
I’ve also written about the top pruning mistakes that ruin a mulberry harvest, and the impulse to over-prune — which is what pollarding essentially is — tops that list. It’s not that you’re doing something wrong, technically. It’s that you’re optimizing for the wrong outcome.
When Pollarding Actually Makes Sense for Home Growers
That said, there are genuine scenarios where pollarding might be right for you. Let me paint them:
- You inherited a pollarded tree and want to maintain it for its historical or ornamental value
- You have extremely limited space and need a mulberry that stays very compact and controlled
- You’re growing mulberry primarily for the leaves (maybe you keep silkworms, or you forage the leaves for tea)
- You love the aesthetic and accept upfront that you’re choosing looks over quantity of fruit
If any of those describe you, then yes — I can absolutely walk you through how to establish and maintain a pollarded mulberry. But if you’re reading this because you want to maximize your berry yield, I’d genuinely encourage you to explore standard pruning techniques instead. You’ll get more fruit, faster regrowth to productive size, and far less work in the long run.
Understanding what to realistically expect from your tree is important here too — what to realistically expect from mulberry tree growth rate changes dramatically depending on how you prune it. A standard pruned tree reaches productive size much faster than a heavily pollarded one.
What I Use for Heavy Pruning
If you do decide that pollarding is right for your situation, you’ll need good tools. Heavy pruning work — especially the kind needed to establish pollard knuckles — demands equipment that won’t make you want to cry halfway through.
The Fiskars PowerGear2 Bypass Lopper — 28″ with 2″ Cut Capacity has been my workhorse for years. The 28-inch length gives you reach and leverage, and that 2-inch cut capacity means you can handle the branches you’ll encounter on a mature mulberry without wearing your hands out. The bypass action is clean and doesn’t crush the wood, which matters when you’re making those precise cuts on your pollard knuckles.
After you’ve made those cuts, protecting them matters. Tanglefoot Tree Wound Pruning Sealer and Grafting Compound — 12 oz is what I use to seal fresh cuts on my trees. It encourages proper healing and keeps out moisture that could otherwise invite disease. Mulberries are tough, but they appreciate a little aftercare when you’ve cut them hard.
The Real Question: Is It Right for Your Tree?
Here’s what I want you to take away from this: pollarding mulberry trees is not a bad technique. It’s a legitimate, historically proven method with real uses. But it is a specialized technique, and it has genuine tradeoffs that don’t always align with what home growers actually want.
Before you commit to establishing a pollard framework on a young tree, ask yourself honestly: am I doing this because I want the aesthetic, or because I want to maximize my harvest? Your answer determines everything. There’s no judgment either way — I just want you to make the choice with your eyes wide open.
That reader from the UK with the photo of those knobby stumps? I advised her to leave the tree alone and let it recover to a more productive form. The pollarding had been abandoned, and the tree was halfway between two different growing habits, which was making it weak. Once we reframed her goal — from maintaining a historical structure to getting berries — the path forward became much clearer. Last I heard from her, she had a beautiful, productive tree again.
Whatever you decide, I’m here for it. Want to talk through whether pollarding is right for your specific situation? Drop me a note. Want to explore other pruning approaches that maximize your harvest? Head over to my guides and let’s dig in together. Your mulberry tree is worth getting right.
