Spring might seem like the perfect time to refresh your garden, but not all perennials agree! Some plants would rather stay put until a different season before they’re ready for a split.
Trust me, I’ve learned the hard way that dividing at the wrong time can lead to some sad, struggling plants.
So, let’s take a closer look at which perennials prefer a different schedule, when they actually want to be divided, and how to do it without stress—because gardening should be fun, not frustrating!
1. Peonies
Oh, how they remind me of grandma’s garden! These beauties should stay put in spring as they fancy a good nap until fall for any dividing adventures.
Why rush them when they can thrive in their own time, right? I once hastily divided them in spring. Lesson learned, they sulked all season.
Wait until fall when their growing energy is low to gently divide them, and you’ll be rewarded with blooms galore. Just keep in mind, they like a bit of patience!
2. Irises
These are like the rockstars of the garden—bold and beautiful. But even rockstars need a break, and spring isn’t their time for division.
Let them enjoy the stage until late summer when they’re ready for an encore.
Dividing them in spring leads to fewer flowers, and who wants that? I’ve seen irises bloom robustly when divided at the right time.
So, grab your spade in August and let these beauties shine anew. Trust me, the extra blooms will be worth the wait!
3. Hostas
Ah, hostas! These leafy wonders thrive in the shade, making them the ideal friend for your shady spots. Spring division? Skip it. Hostas prefer a late summer or early fall refresh.
Dividing now can stunt their growth, and that’s not the kind of surprise you want. Back when I tried spring division, the hostas looked more like sadas!
For a beautiful look come spring, give them a gentle split in late summer. They’ll thank you with their foliage dance.
4. Lilies
Do lilies not just make you pause and admire their grace? It’s tempting to divide them in spring, but resist the urge. Why not ponder the best time over a cup of tea?
Lilies like to be divided in the fall, after they’ve stored up energy. Spring division might lead to a flower fiasco with fewer or no blooms.
So, if you’ve ever wondered why your lilies didn’t bloom, maybe it’s because they were divided too soon. Fall’s their preferred time for a little me-time. Patience pays off!
5. Bleeding Heart
A romantic, yet delicate garden addition. Dividing it in spring? A definite no-go. Instead, let it grow undisturbed until fall for the best blooms.
Rushing these lovely hearts in spring might stop their flowering parade. I’ve let them flourish untouched until fall, and they’ve rewarded me handsomely.
So, when’s the right time? When the leaves start to fade, dig in and give them a gentle separation to enjoy a heart-filled spring next year.
6. Oriental Poppies
Bright and cheerful, Oriental poppies are the life of the garden party. But spring division? Absolutely not! These poppies prefer a summer break for dividing.
Try dividing in spring, and you might be met with a rebellious flower strike. I learned this the hard way when my poppies went on a bloom hiatus.
Wait for mid-summer, when they’re resting post-bloom, to divide them. Your patience will be rewarded with a burst of color the next season.
7. Hellebores
The shy woodland wonders. They are best left alone in spring. I’ve always loved their early blooms in my garden, but dividing them in spring? A rookie mistake!
They’re best divided in late summer or early fall. One year, I divided mine in spring and the poor dears sulked all year.
Give them a rest until late summer, and you’ll have a happy hellebore family. Trust me, they’ll reward you with their charming blooms when treated right.
8. Baptisia (False Indigo)
This one is standing tall and proud. But dividing in spring? Better not. They enjoy a late fall division.
Spring division might lead to a grumpy plant with sparse flowers. I’ve learned to let them bask in their summer glory before dividing.
Wait until fall, and they’ll be ready to multiply without the fuss. Trust these fellows to bring life back into the garden with their striking blue flowers when divided at the right time. You can’t go wrong with baptisia.
9. Monkshood
With their blue flowers, these are best left untouched in spring. They’re not keen on a spring split and won’t shy away from showing it.
Dividing in spring can result in a lackluster display of blooms. I’ve observed a more robust bloom when they’re divided in late summer.
If you wait until the dog days of summer, Monkshood will reward you with their deep blue elegance. They’re worth the patience and promise a stunning show come next bloom season.
10. Lungwort
Do you ever wonder about lungwort’s speckled charm? Dividing them in spring isn’t their style. A late summer division is more like it, wouldn’t you agree?
Attempting a spring split can dampen their spirits and reduce flowering. Have you, too, noticed their reluctance to bloom when divided too early?
Let them thrive through the summer, and when fall whispers, divide them gently. Their unique appeal is worth the wait for a full-flowered display next spring!
11. Columbine
Columbines, with their flowers, bring a touch of magic to any garden. Avoid spring division. These beauties prefer a summer split.
Rushing to divide them in spring can lead to fewer flowers, and who wants to miss out on their enchanting display?
Come late summer, they’re more than happy to oblige a gentle division. Treat them well, and they’ll return the favor with their delightful blooms, making your garden a fairy tale come true!
12. Gas Plant (Dictamnus)
The enigmatic gas plant is best left alone in spring. I once tried a spring division, and they weren’t pleased with me at all!
These plants prefer a fall division when they’re done delighting with their fragrant blooms. They hold a bit of magic, and rightly so, as they can be quite temperamental.
Wait until fall for dividing, and these beauties will reward you with their aromatic allure. Trust me, patience truly pays off with these unique characters!
13. Goatsbeard
This one thrives in the cool shade. Spring division? Not so much. They’re happier with a summer or fall division.
Spring division can be a bit of a letdown, resulting in fewer flowers. I once tried it, and the goatsbeard wasn’t too pleased.
Give them a chance to shine by dividing them in late summer. They’ll fill your garden with their graceful beauty, adding a touch of elegance to any shady spot.

Ever marveled at butterfly weed’s colors? They prefer a late fall division, and isn’t that surprising?
Dividing in spring can lead to fewer blooms, leaving butterflies unimpressed. Have you faced the same perplexing lack of flowers after a premature division?
Allow them to bask in summer’s warmth and divide in late fall. Their bright orange flowers will be back in full force, attracting butterflies like a magnet next season!
15. Russian Sage
Russian sage, with its silvery foliage and purple spires, is a garden staple. But spring division? Better left aside. They prefer a fall refresh for best results.

These won’t take kindly to a spring division. I learned this firsthand when I thought an early division would boost blooms.
Instead, fall is their time to shine when it comes to dividing. Once divided in fall, they flourished, rewarding me with a sea of color.
Patience is key for these beauties. Allow them to enjoy the summer, and they’ll return the favor with their towering spikes come next bloom season.
