Spring gardening rarely looks like a magazine cover.
It usually starts with me kneeling in half-frozen muck, my lower back throbbing, staring at the decayed, slimy remnants of last year’s garden.
My fingernails carry a permanent rim of dark soil by mid-March.
That damp, earthy smell of thawing compost is your signal to get to work.
If you are wondering what to do for peonies in spring, the answer begins right down in the dirt.
You will see those strange, alien-looking crimson nubs pushing up through the cold earth.
They look delicate, but those “eyes” are tough little survivors that have weathered the winter freeze.
Let us get the unpleasant chores out of the way first.
Sanitation: Battling the Scourge of Botrytis
The biggest mistake you can make right now is leaving last year’s dead foliage sitting on the crown.
I learned this the hard way during a particularly wet spring a decade ago.
I was too lazy to clear the beds, and by May, my entire peony border smelled sour, like old dishwater.
That is the scent of Botrytis blight.
According to the Missouri Botanical Garden, Botrytis paeoniae thrives in cool, wet spring conditions.
It turns those firm, hopeful red shoots into a foul, blackened mush right at the soil line.
You must remove every single piece of dead debris from around the plant.
Do not toss this diseased junk into your compost pile.
Bag it up and throw it in the municipal trash to keep the fungal spores out of your yard.
Carefully pull weeds like bindweed or creeping Charlie away from the emerging shoots.
The satisfying rip of a weed’s taproot sliding out of wet clay is one of the few perks of early spring chores.
Hardware First: Wrangling the Future Beast
Let me back up a second.
Before those shoots get taller than four inches, you need to install your plant supports.
Do not wait.
Trying to shove a metal grow-through grid over a bushy, two-foot-tall herbaceous peony in late May is an exercise in pure frustration.
The stems will snap.
You will curse, your knees will ache from crouching, and you will be left holding a fistful of ruined foliage.
Put the hardware in the dirt now.
Center the metal hoop or grid directly over the red eyes.
As the plant grows, it will push up naturally through the grid, hiding the rusty metal beneath its leaves.
Some folks use twine and bamboo, which is fine if you have the patience to tie them up later.
I prefer the lazy reliability of a heavy-gauge steel ring.
Feeding: The Danger of Loving Your Plants to Death
Over-nurturing is a tough habit to break.
Back in 1998, I managed to rot the roots right off a rare Paphiopedilum orchid collection.
I hovered over them with a watering can every day, convinced my constant attention was helping.
Peonies demand the same hands-off respect.
When considering what to do for peonies in spring, dumping high-nitrogen fertilizer on them is a fast track to failure.
Nitrogen fuels rapid, weak leaf growth at the expense of root strength and flowers.
You will end up with a floppy green bush that falls over in the first mild breeze.
Instead, wait until the shoots are about three to four inches tall.
Scratch a handful of bone meal or a low-nitrogen organic bulb fertilizer into the top inch of soil around the drip line.
Keep the fertilizer away from the actual stems to avoid burning them.
If your soil is already rich with good compost, you might not need to feed them at all.
Real gardening often involves doing nothing and trusting the soil biology to do its job.
Watering: Navigating the Mud and Dust
Spring weather is chaotic and unpredictable.
One week your boots are sinking three inches into the mud, and the next week the wind turns the topsoil to dust.
In 2005, I spent a grueling season trying to acclimatize moisture-loving tropicals in a harsh, dry western climate.
It was a daily slog of dragging a heavy, kinked hose around just to keep things barely alive.
That experience taught me to hyper-focus on soil moisture levels.
Peonies hate standing water.
Their thick, fleshy taproots will turn to mush if they sit in a puddle.
However, they do need consistent moisture as those tight, hard flower buds begin to swell.
If your spring is typically rainy, put the hose away.
If you hit a dry spell of more than ten days, give them a deep, slow soak at the base of the plant.
Never spray the foliage if you can avoid it, as wet leaves invite that wretched Botrytis back into the picture.
The Ant Situation: Leave Them Alone
Every single spring, I get frantic questions from newer gardeners about pests.
They see large black ants marching all over their swelling peony buds.
They ask me what kind of insecticidal soap or poison to spray on them.
My advice is simple: put the spray bottle down.
The ants are not eating your flowers.
Peony buds secrete a sticky, sweet nectar that the ants harvest for food.
In return, the ants aggressively defend the bud from other insects that might actually chew through the petals.
It is a temporary, harmless biological transaction.
Once the flower opens, the nectar dries up, and the ants pack their bags and move on.
Just flick them off if you cut the stems to bring inside the house.
Tree Peonies: A Different Animal
We need to make a quick distinction if you grow woody tree peonies instead of the standard herbaceous types.
Herbaceous peonies die back to the ground every winter.
Tree peonies maintain a woody, shrub-like structure above ground all year long.
Do not chop down a tree peony in the spring.
I did that once in my twenties, thinking I was cleaning up dead wood, and I lost an entire year of growth.
For tree peonies, just inspect the branches and prune out anything that is obviously brittle and dead.
Wait until you see the leaf nodes swelling before you make any cuts.
That way, you know exactly which wood is alive and which wood lost the winter battle.
The Urge to Divide (And Why You Should Resist)
Spring fever makes people want to dig things up and chop them into pieces.
Resist this urge when it comes to your peony beds.
Digging up a mature peony in wet, cold spring soil is asking for trouble.
The roots bleed sap, and the damp soil encourages fungal pathogens to enter the open wounds.
Plus, you will likely destroy this year’s bloom cycle entirely.
If a clump has grown too large or stopped blooming, mark your calendar for late September.
Fall is the proper time to lift, divide, and replant those fleshy roots.
Spring is for observing, cleaning, and supporting.
Managing Late Frosts
Just when you think you are safe, April throws a nasty late freeze your way.
I cannot count the number of nights I have spent stumbling around the garden at 10 PM with a flashlight.
I haul out old bedsheets, tarps, and inverted plastic pots to cover the tender shoots.
The cold, wet fabric clings to your hands, and the wind fights you for every inch.
Peony foliage can handle a light frost.
Those deep red stems are surprisingly resilient to a quick dip below freezing.
However, if the plant has already formed flower buds and a hard freeze hits, those buds will abort.
They will turn brown, dry up, and fall off, leaving you with nothing but leaves for the year.
Keep a close eye on the weather forecast.
If temperatures threaten to drop into the mid-twenties, cover your plants overnight.
Always remove the covers first thing in the morning.
If the sun hits a plastic tarp covering a plant, you will accidentally bake the foliage.
Protecting the Soil Structure
One last piece of advice on what to do for peonies in spring concerns your feet.
Stay out of the beds when the soil is saturated.
Stomping around in wet clay forces all the air pockets out of the dirt.
This process is called compaction, and it slowly suffocates the plant’s root system.
According to the Royal Horticultural Society, compacted soil restricts drainage and leads directly to root death.
If you must get in there to weed or place your metal hoops, put down a wide wooden board.
Kneel or step on the board to distribute your weight.
It makes the chore a bit more cumbersome, but your plants will thank you later.
Gardening is rarely easy.
It is a constant negotiation with weather, pests, and your own physical endurance.
But when those massive, heavy blooms finally open in late May, you realize the muddy slog was worth the effort.
