How To Take Hydrangea Cuttings Monty Don

You know those hydrangea bushes? The ones that look like they’re wearing fluffy pink or blue ballgowns in the summer? Yeah, those. The ones that make your garden look like it's hosting a fancy garden party, even if your only guests are the neighbourhood squirrels who are probably judging your taste in garden gnomes. Well, turns out, you can basically multiply those magnificent floral displays without selling a kidney or entering a horticultural lottery. And the best part? It’s surprisingly easy. Like, “accidentally ordering too much pizza and then realizing you’re actually okay with it” easy.

Now, before you picture yourself wrestling with a thorny rose bush, let’s talk hydrangeas. These beauties are famously generous. They’re practically begging you to share their fabulousness. And the secret to doing that? Taking cuttings. It sounds fancy, doesn’t it? Like something you’d only do in a pristine, climate-controlled greenhouse with a lab coat on. But nope. You can totally do this from your own garden, probably in your gardening wellies that have seen better days.

My first foray into hydrangea propagation was a bit of a ‘wing it and see what happens’ situation. I’d seen Monty Don, bless his tweed-clad heart, doing his thing on Gardeners' World, making it look as simple as making a cuppa. He’d just snip, snip, and voilà, a new bush was born. I figured if he could do it without breaking a sweat (or at least without his perfectly coiffed hair falling out of place), then surely I could give it a go. After all, what’s the worst that could happen? A bit of leaf litter? A slight sense of mild horticultural disappointment?

Turns out, the worst that could happen is that you end up with a whole new army of hydrangeas, which, honestly, is more of a problem for your neighbours who are going to start giving you that look when they see your driveway overflowing with potted plants. But let’s not get ahead of ourselves. First, we need to get these little beauties started.

When to Strike Gold (or Pink, or Blue)

The golden rule, according to the wise (and often rain-soaked) sages of the gardening world, is to take your cuttings when the plant is in its prime. Think late spring or early summer. This is when the new growth, what we botanists (okay, what gardeners call) softwood cuttings, is flexible and full of life. It’s like they’re at their peak performance, ready to take on the world, or at least the potting mix.

You're looking for those bits of stem that are green and bendy, not the woody, old stuff that feels like it’s about to break your secateurs. Imagine a teenager – full of energy, a bit bendy, and definitely not ready to be put out to pasture. That’s the kind of growth you want. If it snaps with a satisfying crack, it's probably too woody. We want a gentle bend, a subtle sigh of flexibility.

And here's a little tip: the best time of day is usually in the morning, after the dew has dried. This is when the plant is most hydrated and perky, like you after your first coffee. Trying to take cuttings in the midday sun is like trying to have a deep conversation with someone who’s just run a marathon – they’re probably not at their best. So, early morning, sunshine… it’s a date.

The Tools of the Trade (Don't Panic, It's Not Rocket Science)

Now, let's talk tools. You don't need a fancy arsenal. A sharp pair of secateurs is your best friend. Clean them! Seriously. Bits of old plant goo can carry diseases, and we’re trying to create new life here, not send it to the great compost heap in the sky prematurely. Think of it like washing your hands before you prepare food – a basic hygiene thing, but crucial for success.

You'll also need some small pots or trays, some good quality seed and cuttings compost (this is important – regular garden soil is too heavy and can compact, like trying to jog in concrete boots), and a bit of enthusiasm. Oh, and maybe a nice cup of tea to fuel your gardening adventures. Because gardening is always better with tea.

Some people swear by rooting hormone. It’s like a little pep talk for the cutting, encouraging it to sprout roots. You can get it as a powder or a gel. If you’re feeling adventurous, give it a go. If not, don't stress. Hydrangeas are pretty forgiving. Think of it as optional sprinkles on your horticultural cupcake.

The Snipping Ceremony

Alright, the moment of truth. Find a healthy-looking stem. You want to make a cut just below a leaf joint, or a node. This is where the magic happens, where the plant is primed to send out new roots. Imagine it’s like finding a secret doorway on the stem. The cut should be clean and at a slight angle, just to give it a bit more surface area to get its roots going. Think of it like giving the little guy a good handshake.

When you're selecting your stem, aim for one that's about 10-15 cm (4-6 inches) long. It doesn't need to be a skyscraper. And crucially, remove the lower leaves. You only want to leave a couple of leaves at the top. Why? Because those leaves will drink up all the moisture, and if there are no roots to replace it, your cutting will shrivel up faster than a raisin left in the sun. We want to preserve moisture, not drain it dry. So, strip those bottom leaves like you’re getting ready for a spa day, leaving just the essentials.

If your cutting has any flowers or flower buds on it, snip them off too. They’re energy-sapping divas. We want all that energy going into root development, not into putting on a premature floral show. Let them focus on the important stuff first, like getting established. Think of it as saving the best for last.

Potting Up the Tiny Terrors

Now for the planting. Grab your pots and fill them with that special seed and cuttings compost. Give it a gentle water so it’s nicely moist, but not sodden. You don't want it to look like a mini swamp. Nobody likes a soggy bottom, not even a plant cutting.

Make a little hole in the compost with your finger or a pencil. If you’re using rooting hormone, dip the cut end of your hydrangea cutting into it now. Just a little dip, don't go overboard. Then, gently insert the cutting into the hole. Firm the compost around it so it stands up straight and proud. It’s like tucking a baby into bed – snug and secure.

You can put one cutting per small pot, or several in a larger tray. If you’re putting multiple in a tray, give them a bit of personal space. They don’t want to be all up in each other’s business just yet. Imagine them as housemates who haven’t quite bonded. They need their own little corners.

The Greenhouse Effect (Without the Greenhouse)

This is where the magic really starts to happen, and it’s surprisingly simple. To keep the humidity high and stop those leaves from wilting, you need to create a mini greenhouse effect. The easiest way to do this is to pop a clear plastic bag over the pot. You can use a zip-top bag or even a cut-off plastic bottle. Just make sure it’s clear so the light can get through, and try to keep the bag from touching the leaves too much.

You can use little stakes to prop up the bag if needed. Think of it as creating a cozy little bubble for your cuttings. It’s like giving them a warm, humid hug. This is crucial for them to survive and thrive.

Place your pots in a bright spot, but out of direct sunlight. Direct sun will cook them faster than a poorly timed BBQ. Think dappled shade, or a bright windowsill that doesn’t get blasted by the afternoon sun. It’s like finding the perfect spot for a sun-worshipper – warm, but not scorching.

Keep an eye on the compost. It should stay consistently moist, but not waterlogged. You might need to mist the inside of the bag occasionally if it looks a bit dry. You're basically trying to recreate that perfect, steamy greenhouse environment. It’s the spa treatment for your future hydrangeas.

Patience, Young Grasshopper

Now comes the hardest part for most of us: waiting. Hydrangea cuttings can take anywhere from four to six weeks to start showing signs of rooting. You might see new leaf growth, or if you gently tug on the cutting (and I mean gently, like you're testing if a marshmallow is toasted), you might feel a bit of resistance, meaning roots are forming.

Don't despair if you don't see anything for a while. Some plants are just fashionably late to the root party. Keep them in their warm, humid environment and resist the urge to constantly poke and prod. Gardening is a lot like parenting in this regard – sometimes you just have to trust the process and let things happen.

When you see clear signs of good root development – sturdy new growth, and the cutting feels well-anchored – it’s time to graduate them to slightly bigger pots. Be gentle when you transplant them. Think of it as moving into their first apartment – a bit of a shock, but exciting!

And that, my friends, is how you can end up with a whole jungle of hydrangeas, all thanks to a bit of snipping and a lot of patient waiting. It’s a wonderfully satisfying way to fill your garden with those gorgeous blooms without spending a fortune. Plus, you get to brag about your horticultural prowess. And who doesn’t love a good brag, especially when it involves beautiful flowers?

So, next time you’re admiring those magnificent hydrangeas, remember this little trick. You too can be a hydrangea-producing machine. Just grab your secateurs, a cuppa, and get snipping. Your future garden, and your neighbours’ envy, will thank you for it.
