Yes, you can absolutely split lavender and replant it to create new plants.
In fact, dividing lavender is one of the easiest ways to multiply your garden favorites.
If you have an older lavender shrub that’s looking woody or sparse, splitting lavender and replanting the divisions can give those plants a fresh start.
When you split lavender and replant, you’re essentially taking one established plant and turning it into several healthy new ones.
This is a common question from gardeners, and the good news is that yes, you can split lavender and replant it successfully with the right timing and technique.
In this post, we’ll walk through why you can split lavender and replant it, when to do it, how to do it step by step, and what to avoid so your lavender thrives after the move.
Let’s dig into the details.
Why You Can Split Lavender And Replant It Successfully
Lavender is a hardy perennial that responds well to division when done correctly.
Many gardeners wonder whether lavender can handle being split, since some woody perennials don’t recover well from root disturbance.
But lavender is different because it grows from a central crown that produces multiple stems and root clusters.
When you split lavender and replant those sections, each piece retains enough roots and growth points to establish itself as an independent plant.
Here are the key reasons why splitting lavender and replanting works so well.
1. Lavender Produces Multiple Crowns Over Time
As lavender matures, it naturally forms several crowns at the base of the plant.
Each crown has its own set of roots and shoots.
When you split lavender and replant, you’re separating these crowns so each one gets its own space to grow.
That’s why splitting lavender isn’t just possible, it’s actually beneficial for older plants that have become overcrowded.
2. Division Rejuvenates Woody Lavender
Older lavender plants often turn woody at the base with fewer leaves and fewer flowers.
When you split lavender and replant, you remove much of that old woody growth.
This encourages fresh green shoots to emerge from the roots of each division.
Splitting lavender gives the plant a second chance at vigorous growth that it might not achieve on its own.
3. Root Health Improves After Splitting
Lavender roots can become tangled and compacted if left alone for too long.
When you split lavender and replant, you’re trimming those roots and giving them room to spread into new soil.
This leads to better water absorption and nutrient uptake.
Healthy roots mean a healthier lavender plant that will bloom more profusely.
4. More Plants Means More Blooms
Splitting lavender and replanting means you multiply your lavender supply for free.
Instead of buying new lavender plants, you can divide one large plant into three or four smaller ones.
That gives you more fragrant flowers for drying, sachets, and cooking.
So yes, you can split lavender and replant to expand your garden without spending a dime.
When Is The Best Time To Split Lavender And Replant
Timing is everything when you split lavender and replant.
Lavender is sensitive to transplant shock, so you need to pick a season when the plant is most likely to recover.
The best time to split lavender is in early spring, just as new growth begins to appear.
You can also split lavender in early fall, but only if you live in a mild climate.
Here’s why spring is the ideal window for splitting lavender and replanting.
1. Spring Gives Lavender Time To Establish Roots
When you split lavender and replant in spring, the soil is warming up and rain is usually more abundant.
This gives the newly divided roots a chance to settle in before summer heat arrives.
If you split lavender too late in the season, the plant won’t have enough time to root before winter.
2. Avoid Splitting Lavender During Flowering
Never split lavender while it’s actively blooming.
Flowering takes a lot of energy, and when you split lavender and replant during bloom, the plant is too stressed to recover.
Wait until after the first flush of flowers has faded or before buds appear.
This way, the lavender can focus all its energy on root production after you split it.
3. Mild Fall Days Work For Warm Climates
If you live in zone 8 or warmer, you can split lavender in early fall.
The cooler temperatures reduce stress, and the plant has a few weeks to establish before frost.
But in colder regions, you should stick to spring when you split lavender and replant.
Winter frosts can kill newly divided lavender that hasn’t rooted properly.
How To Split Lavender And Replant Step By Step
To get the best results, follow this straightforward process when you split lavender and replant.
Gather a sharp spade, pruning shears, and fresh potting soil before you begin.
Here are the steps you need to take to successfully split lavender and replant.
1. Water Your Lavender A Day Before Splitting
Hydrated lavender is easier to split.
Water the plant thoroughly the day before you plan to split lavender and replant.
Moist soil clings to the roots better, reducing damage during digging.
Dry lavender roots are brittle and break easily when you split the plant.
2. Dig Around The Lavender Root Ball
Use a spade to dig a circle around the lavender, about 6 to 8 inches from the stem base.
Dig deep enough to loosen the entire root system.
Once the root ball is loose, lift the plant out of the ground gently.
Now you can split lavender into sections using your hands or a clean knife.
3. Separate The Crowns And Roots
Look for natural divisions where stems and roots separate.
Make sure each section you split lavender into has at least a few healthy roots and green shoots.
If the center of the plant is woody and dead, discard that part.
You only want to replant sections that show signs of new life.
4. Replant Each Section Immediately
Don’t let the roots dry out while you’re deciding where to plant.
Dig a hole slightly wider than the root ball of each division.
Place the lavender in the hole at the same depth it was growing before you split it.
Backfill with soil and press firmly to remove air pockets.
5. Water Well And Mulch Lightly
After you split lavender and replant each piece, water them deeply.
This helps the soil settle around the roots.
Add a thin layer of gravel or coarse sand around the base to improve drainage.
Avoid heavy mulch, as lavender hates wet feet, and too much moisture will rot the roots.
Common Mistakes When You Split Lavender And Replant
Splitting lavender is simple, but a few common errors can lead to plant failure.
Avoid these pitfalls to ensure your divisions survive.
1. Splitting Lavender That’s Too Young
Don’t split lavender that’s under two years old.
Young plants haven’t developed enough root mass to survive division.
Wait until your lavender is at least three years old before you split lavender and replant.
This gives the plant time to build a strong base that can handle splitting.
2. Planting Divisions Too Deep
When you split lavender and replant, don’t bury the stems.
Lavender needs good air circulation at the base.
If you plant too deep, the stems will rot quickly.
Keep the top of the root ball level with the surrounding soil.
3. Overwatering After Splitting
Yes, you should water after you split lavender, but don’t overdo it.
Too much water right after splitting lavender and replanting can cause root rot.
Let the soil dry out slightly between waterings during the first few weeks.
Lavender prefers dry conditions, even when it’s recovering from being split.
4. Splitting Lavender During Hot Afternoons
Always split lavender in the morning or on a cloudy day.
Direct sun and heat stress the plant immediately after you split lavender and replant.
If you have to split on a warm day, do it early and provide temporary shade for a few days.
This reduces transplant shock significantly.
So, Can You Split Lavender And Replant?
Yes, you can split lavender and replant it successfully if you follow the right steps.
Lavender responds beautifully to division when done in early spring and with proper care.
The key is to split lavender into sections that each have healthy roots and shoots.
When you split lavender and replant, you rejuvenate old plants and multiply your lavender for years of fragrance.
Remember to avoid young plants, don’t plant too deep, and water sparingly after you split.
Hope this guide helps you confidently split lavender and replant with excellent results.
