Looking for ways to grow your garden and keep plants happy without breaking the bank? Dividing perennials is essential to a healthy garden. Today I’m sharing how to divide perennials in 5 easy steps.
How Dividing Perennials Has Grown My Garden
My home started with a few plants when we first moved here.
One of the reasons I have so many gardens is because I divided plants and created new beds.
My gardens started with one small flower garden and grew to several.
Fast forward 22 years and now I have expansive gardens throughout the property.
What I love most is that I divided easy care plants that didn’t need a lot of coddling from me to grow and thrive.

Why Dividing Perennials is Important
Dividing perennials is a great way to keep the garden looking good and share the bounty with others.
There are several reasons why we need to divide perennials every few years.
For starters, dividing perennials keeps plants growing and healthy.
As they mature, perennials start growing in larger clumps that start to separate.
Sometimes these clumps form a hole in the middle of the plant.
When gardeners see this natural division, it is time to divide the plant.
This Sedum ‘Autumn Joy” needs to be divided. This is one plant but looks like five.
The plant is letting me know it needs to be divided.
Moreover, as perennials grow they start overcrowding themselves as well as neighboring garden plants.
Overcrowding leads to fewer or smaller blooms due to receiving fewer nutrients, light, and air circulation.
Therefore, dividing more vigorous plants keeps them in check so they don’t take over the garden and crowd out other varieties.
Finally, dividing perennials saves a lot money because it multiplies the stock. One plant can be divided into several.
This means gardeners have more plants to enjoy in their own gardens or their divisions can be shared with others.
As much as I love to create more gardens in my yard, I love sharing my plants with others.
It is so fun to see how they grow in my friends’ gardens and even more fun to receive new plants or varieties that I didn’t already have from others.
When to Divide Perennials
NOTE: I live in New Jersey so my perspective is based on the climate here in New Jersey. Please check with your local cooperative extension if your climate and hardiness zone are different as timing may or may not differ.
In general, dividing perennials should be done in spring or fall when the temps and weather are most seasonable.
It is better and easier to transplant divisions while plants are small or as they begin to go dormant.
I highly recommend avoiding summer divisions and transplants. While it can be done, the success rate is very low.
Most of my gardens were started with perennials that were divided.
Since New Jersey weather is more seasonable during early spring or mid-late fall, I divide and transplant my perennials at that time.
I prefer to do it when I don’t have to coddle transplants through the re-acclimation process.
For me, it’s much easier than doing it in late spring through early fall when the weather is hot and humid.
This is not to say it can’t be done from late spring through early fall because it can.
However, for me, it is much more work to establish transplants as the temps, heat, and humidity soar.
Since I prefer less work and maintenance to establish divisions, I divide in early spring or mid-late fall.
I also like to divide perennials in early spring when they are smaller in size. It is easier and less damaging when you work with younger plants.
However, if I don’t get a chance to divide in early spring, I’ll wait until the plants start to go dormant in mid-late fall when I don’t care what the plant looks like after I divide and transplant it.
Another benefit to waiting until mid-late fall is that plants have more time to grow stronger root systems from fall through early spring.
How to Divide Perennials
- Depending on the size of perennials, you’ll either need a trowel or spade shovel to divide perennials.
- Look at the plant and determine where the natural lines of division are.
- Start with an outer edge of the plant. Dig the shovel underneath the plants and avoid slicing the roots as much as possible. Some plants will lift out very easily with one simple dig and use of your hands. Others will require more effort where you will need to dig around the entire section of the plant.
- Don’t worry about injuring plants during this process. They will regenerate, bounce back, and thank you for the effort you put in.
- Once the divisions are out, transplant them as soon as possible.
Start with an outer edge of the plant.
And try to avoid slicing the roots.
Then work your way getting the shovel underneath the plant.
Once it’s under the plant, try to lift it out gently.
Sedum typically comes out pretty easily.
But other plants need a little more work.
Once the plant is divided, it looks so much neater than before.
Plus we have more plants to add to other gardens or give away to friends.
I relocated two of the divisions to the mailbox garden.
Isn’t that so easy?
Some plants are much tougher to divide than others.
But it is well worth the effort.
