When the fall season arrives, what you do with daisies in the fall depends on the type you’re growing and how much effort you want to put into next year’s bloom.
The main thing you do with daisies in the fall is to cut them back, divide them, and prepare them for winter dormancy so they come back stronger in spring.
If you’ve been wondering what you do with daisies in the fall, the short answer is simple: you tidy them up, protect their roots, and let them rest.
In this post, we’ll walk through the exact steps for what you do with daisies in the fall, including pruning, dividing, mulching, and even saving seeds.
Let’s dig in.
What You Do with Daisies in the Fall: The Core Care Steps
The most important thing you do with daisies in the fall is to get them ready for cold weather without stressing them out.
Daisies are hardy perennials, but they still need a bit of help to survive harsh winters.
Here’s the breakdown of what you do with daisies in the fall to keep them healthy.
1. Cut Back the Foliage After the First Frost
One of the first things you do with daisies in the fall is to prune the spent stems and leaves.
Wait until after the first hard frost has killed off the top growth, because cutting too early can encourage new shoots that will just die in the cold.
Once the foliage turns brown and crispy, use clean pruning shears to cut the daisies down to about two inches above the soil line.
This is a key step in what you do with daisies in the fall because it removes any hiding places for pests and reduces the risk of fungal diseases overwintering in the plant debris.
2. Divide Overgrown Clumps
Another important thing you do with daisies in the fall is to divide them if they’ve become crowded.
Daisies spread quickly, and after a few years, the center of the clump can die out while the outer ring keeps growing.
When you divide daisies in the fall, you’re essentially giving each plant more room to breathe, which leads to better airflow and more vigorous blooming next season.
Carefully dig up the entire clump with a garden fork, then split it into smaller sections with your hands or a sharp spade.
Each division should have a healthy chunk of roots and a few sets of leaves.
Replant the divisions immediately at the same depth they were growing before, and water them well to help the roots settle in before the ground freezes.
This is truly one of the most rewarding things you do with daisies in the fall because you get more plants for free.
3. Apply a Layer of Mulch for Winter Protection
When you think about what you do with daisies in the fall, mulching should always be near the top of your to-do list.
After the ground starts to freeze, apply a two to three inch layer of shredded bark, straw, or leaves around the base of each plant.
The mulch acts like a warm blanket, keeping the soil temperature steady and preventing the freeze-thaw cycles that can heave daisies right out of the ground.
Just make sure you don’t pile the mulch directly against the stems, as that can trap moisture and cause rot.
So when you’re deciding what you do with daisies in the fall, remember that mulching is your insurance policy for a successful spring.
4. Water Deeply Before the Ground Freezes
It might seem counterintuitive, but one thing you do with daisies in the fall is to give them a deep watering before winter sets in.
Evergreen roots stay active in late fall, and they need moisture to store up energy for the long dormancy ahead.
If you live in a dry region, water the daisies thoroughly after pruning and dividing, then let nature take over once the ground freezes.
Aim to stop watering once temperatures consistently stay below freezing, because waterlogged soil can suffocate the roots.
What You Do with Daisies in the Fall for Different Daisy Types
Not all daisies are the same, so what you do with daisies in the fall varies slightly depending on the species you’re growing.
Let’s break it down by the most common daisy types.
1. Shasta Daisies
Shasta daisies are the classic white petal yellow center flowers, and what you do with daisies in the fall for these is straightforward.
Cut the stems down to the basal rosette of leaves near the ground, and remove any dead foliage.
Shasta daisies are quite hardy, so a light mulch is all they need.
If you want to propagate them, this is also the perfect time to divide them, as they respond well to fall division.
2. Oxeye Daisies
Oxeye daisies are often considered wildflowers, and what you do with daisies in the fall for these is pretty minimal.
You can leave the seed heads on for birds to enjoy, or you can cut them back to tidy up your garden.
Since oxeye daisies are so tough, you really don’t need to mulch them heavily, just a thin layer is plenty.
3. Gerbera Daisies
Gerbera daisies are tender perennials, so what you do with daisies in the fall is a bit more involved.
In colder zones, gerbera daisies won’t survive outdoors, so you need to dig them up and pot them indoors for the winter.
Place them in a bright, cool room and reduce watering drastically until spring arrives.
If you live in a mild climate, simply cut back the foliage and apply a thick layer of mulch to protect the crown.
4. English Daisies
English daisies are low-growing and often treated as biennials or short-lived perennials.
What you do with daisies in the fall for these is to cut back any dead flowers and remove damaged leaves.
English daisies appreciate a light mulch, and you can also divide them if they’ve formed dense mats.
Common Mistakes to Avoid When You Decide What to Do with Daisies in the Fall
Even with good intentions, gardeners sometimes make errors when figuring out what you do with daisies in the fall.
Here are the most frequent ones to steer clear of.
1. Cutting Back Too Early
If you trim the daisies before the first frost, you risk stimulating new tender growth that will get zapped by the cold.
Always wait for the foliage to naturally die back before you prune.
2. Skipping Division
Many gardeners skip division because it seems like extra work, but this is one of the most valuable things you do with daisies in the fall.
Without division, daisies become woody, bloom less, and can even die in the center.
3. Mulching Too Early
If you pile on mulch while the soil is still warm, you might trap heat and encourage rodents to nest near the roots.
Wait until the ground has started to freeze before applying your winter mulch.
4. Leaving Dead Foliage
Leaving the dead stems and leaves can harbor fungal spores and insect eggs.
Part of what you do with daisies in the fall is to clear away all that debris to give your garden a clean slate.
So, What Do You Do with Daisies in the Fall?
What you do with daisies in the fall is to prune them down, divide overcrowded clumps, mulch their roots, and water them deeply before the freeze.
These simple steps ensure your daisies survive the winter and return with a burst of color come spring.
So the next time someone asks what you do with daisies in the fall, you’ll have the full answer ready.
Just remember to tailor your approach based on the type of daisy you have, and you’ll be set for a beautiful bloom season ahead.
Happy gardening.
