You can absolutely split lavender and replant it to create more plants and keep your garden thriving.
If you’ve been wondering whether you can split lavender and replant, the short answer is yes, but timing and technique matter a lot.
Splitting lavender is a fantastic way to rejuvenate older, woody plants and multiply your stock without spending a dime.
In this post, we’ll dive into why you can split lavender and replant it successfully, the best methods to do it, and the common pitfalls you’ll want to sidestep.
Let’s get your lavender looking lush and full again.
Why You Can Split Lavender And Replant It
You can split lavender and replant it because lavender is a hardy perennial that responds well to division when done under the right conditions.
Many gardeners worry that lavender is too fragile to split, but with a careful approach, you’ll find it’s quite doable.
Here’s what makes lavender division work and when it’s truly worth the effort.
1. Lavender’s Growth Habit Allows Division
Lavender grows from a central crown that sends out multiple woody stems over time.
When you split lavender, you’re essentially separating that crown into smaller sections, each with its own root system.
Younger, vigorous lavender plants have plenty of healthy roots to support each divided piece.
So when you split lavender and replant it, you’re giving each new section the chance to establish itself as an independent plant.
That’s why splitting works best on plants that are between three and five years old.
2. Splitting Revives Woody, Tired Plants
Older lavender often becomes woody at the base with sparse foliage and fewer blooms.
When you split lavender and replant it, you’re removing that old, unproductive center and keeping only the healthiest outer growth.
This reinvigorates the plant because each new division has fresh energy to push out new leaves and roots.
So rather than ripping out an old lavender, splitting can actually extend its life for several more productive years.
But keep in mind, if the lavender is extremely old and mostly dead wood, splitting might not save it.
3. Timing Is Everything for Success
You can split lavender and replant it successfully, but only if you choose the right time of year.
Early spring is your best window, just as new growth begins to appear but before the plant puts on too much top growth.
Alternatively, early fall works too because the soil is still warm, giving roots time to establish before winter.
Avoid splitting lavender during hot summer months or freezing winter weather.
The stress of division combined with extreme temperatures will likely kill the split lavender.
How To Split Lavender And Replant It Step-By-Step
If you’re ready to split lavender and replant it, follow these simple steps to give your divisions the best chance of survival.
Grab your gardening gloves, a sharp spade, and some good compost, and let’s get started.
1. Prepare the New Planting Spot First
Before you dig up your lavender, prepare the new location so roots aren’t left exposed for long.
Choose a sunny spot with well-draining soil because lavender hates wet feet.
Dig a hole that’s slightly wider than the root ball you expect to plant, and mix in a little grit or sand if your soil is heavy.
This prep work makes it much easier when you split lavender and replant it quickly.
2. Lift the Entire Lavender Plant Carefully
Use your spade to dig around the plant, about six to eight inches away from the base.
Loosen the soil gently until you can lift the whole root ball out without breaking too many roots.
Try to keep as much soil attached to the roots as possible.
Once it’s out, shake off excess dirt so you can see the natural divisions in the crown.
You’ll often spot where the plant naturally separates into distinct sections.
3. Divide the Root Ball into Sections
Now for the main event: you can split lavender and replant it by pulling or cutting the root ball into pieces.
For smaller plants, you might be able to gently tease the roots apart with your hands.
For larger, woodier plants, use a sharp knife or spade to cut through the crown cleanly.
Aim for divisions that have at least three to five healthy stems and a decent clump of roots attached.
Don’t make the pieces too small because tiny divisions struggle to survive on their own.
Bigger sections establish much faster after you replant them.
4. Trim the Foliage and Roots
Before replanting, trim back the foliage by about one-third to reduce water loss.
The roots need time to regrow, so they can’t support all that top growth at first.
Also, snip off any damaged or rotting roots with clean scissors.
This simple step dramatically increases the chances that your split lavender will thrive.
5. Replant and Water Thoroughly
Place each division into its prepared hole at the same depth it was growing before.
Backfill with soil and press down firmly to remove air pockets around the roots.
Water deeply right after planting to settle the soil.
After that initial watering, let the soil dry out between waterings because lavender prefers drier conditions.
You can split lavender and replant it this way, but don’t overwater in the following weeks.
Common Mistakes When You Split Lavender And Replant It
Even though you can split lavender and replant it, many gardeners fail because of a few avoidable errors.
Let’s walk through the biggest mistakes so you don’t lose your precious divisions.
1. Splitting During the Wrong Season
Splitting lavender during its active bloom or in the heat of summer is a recipe for disaster.
The plant is already stressed from flowering, and the sudden root loss is often too much.
Stick to early spring or early fall as I mentioned earlier.
That’s the only time when you can split lavender and replant it with high success rates.
2. Planting in Heavy, Wet Soil
Lavender originates from the Mediterranean, so it thrives in poor, sandy, well-drained soil.
If you replant your divisions in heavy clay or soil that stays soggy, the roots will rot quickly.
Amend the soil with grit, perlite, or coarse sand to improve drainage.
When you split lavender and replant it, good drainage is non-negotiable.
3. Overwatering After Transplanting
It’s tempting to pamper your newly split lavender with lots of water.
But overwatering is the number one killer of transplanted lavender.
Water deeply once right after planting, then wait until the top inch of soil feels dry before watering again.
Too much moisture encourages root rot, and your split lavender will wilt and die.
So, Can You Split Lavender And Replant It?
Can you split lavender and replant it? Yes, you absolutely can split lavender and replant it successfully when you follow the right steps.
The key takeaway is that you can split lavender and replant it best in early spring or fall, using healthy plants with strong root systems.
The process revives older lavender, multiplies your plants, and keeps your garden full of fragrant purple blooms.
Just remember to prepare new spots in advance, trim foliage, and avoid overwatering after you replant.
Now you’ve got all the know-how you need to split lavender and replant it with confidence.
So grab your spade, pick a mild day, and give your lavender a fresh start through division.
