Taking Geranium Cuttings: My Go-To Method for a Greenhouse Full of Blooms
Every year, as the seasons shift, I get a little sentimental about my geraniums. They’ve been with me through countless springs and summers, and when fall rolls around, I can’t help but think ahead to how I’ll keep their color and cheer alive all winter long in my greenhouse. Over time, I’ve learned that propagation - taking cuttings - is the secret. Not only does it give me a greenhouse brimming with fresh blooms when I need them most, but it also lets me stretch the life of plants I’ve cared for season after season. And if I’m being honest, I get blooms a lot quicker than starting by seed.
Why I Take Geranium Cuttings Every Fall
- A fresh start. I’ve noticed that younger plants from cuttings seem to bloom with more gusto than the older, woody ones. They’re like teenagers - full of energy and eager to show off.
- Saving money. Instead of buying new plants every spring, I love knowing I can fill my greenhouse benches with plants I propagated myself. There’s something so satisfying about seeing rows of blooms and thinking, these all came from my own hands.
- Sentimental value. Some of my geraniums have been with me for years. Taking cuttings feels like preserving a little piece of them.
When I Take My Cuttings
Late summer into early fall has always been my sweet spot. The plants are still active, and I can tuck the cuttings into the greenhouse where they settle in before winter. That way, when the cold arrives, I already have rooted, thriving plants ready to take over. Sometimes, if I’m craving more blooms mid-winter, I’ll sneak in a few cuttings then too. The greenhouse gives me that flexibility.
How I Do It (Step-by-Step)
Choosing the right plant.
I walk through my geraniums and pick the healthiest, happiest one. If a plant has been a star performer all season - constantly blooming, never wilting - that’s the one I go to first.
Looking for the perfect stem.
I’ve learned the hard way not to grab one that’s in full flower. The blooms are gorgeous, but the cutting is more temperamental in growing roots. I aim for a stem that’s about 4–5 inches long, green but sturdy.
Making the cut.
A clean snip just below a leaf node. I always use sterilized scissors - years ago I didn’t, and I lost several cuttings to rot. Lesson learned.
Prepping the cutting.
I strip off the lower leaves, leaving just two or three at the top. If there’s a bud, I pinch it. (That part is still hard for me - pinching a bloom feels wrong, but I remind myself it’s for the greater good!)
Potting up.
I use a light, fluffy mix. I’ve learned to never overwater at this stage. Geranium cuttings hate soggy soil, and more than once I’ve drowned them with good intentions.
Babying them along.
I place them where they’ll get bright, indirect light in the greenhouse. Within 3–4 weeks, a gentle tug usually tells me roots are forming. That never gets old - it feels like magic every time. And, I’ve been known to gently dig one up to see for myself – that may or may not have happened last week.
What I Do with My Older Geraniums
After a few years, geraniums get that woody, leggy look. I used to feel guilty, like I’d failed them, but now I see it differently. They may not bloom like they once did, but they still play a vital role in my greenhouse.
- I prune them back hard, which almost always pushes out new shoots perfect for cuttings.
- I keep them well-fed, because even woody plants surprise me with blooms from time to time.
- Most importantly, I treat them as my “mother plants” - their job is to keep giving me material to work with.
How I Keep the Greenhouse Blooming
Over the years, I’ve developed a rhythm:
- Staggered cuttings. I don’t take them all at once. Every couple of weeks, I’ll start a new batch so I’ve always got plants at different stages.
- Pinching. As soon as the cuttings have a few sets of leaves, I pinch them back. It feels cruel, but it makes for such fuller, bushier plants later.
- Feeding. Once rooted, I give them a diluted liquid fertilizer. I’ve found they really respond, and the blooms keep coming.
Walking into my greenhouse in January and seeing it alive with geranium blooms feels like stepping into spring long before the calendar agrees. Taking cuttings has given me not just more plants, but more joy. And those older, woody plants? They may not be the showstoppers they once were, but they’re the quiet heroes of my greenhouse - steady, dependable, and generous.
If you haven’t tried propagating your geraniums yet, trust me, it’s worth it. A little patience, a few snips, and you’ll have your own winter wonderland of color waiting for you.
