Can You Split English Lavender

Yes, you can split English lavender, and doing so is one of the best ways to rejuvenate an older, woody plant and create new ones for free.
 
Splitting English lavender, also known as dividing lavender, is a straightforward gardening task that can breathe new life into a tired shrub.
 
If you’ve been wondering whether you can split English lavender without killing it, the answer is absolutely yes, as long as you follow a few important timing and technique rules.
 
In this post, we’ll explore exactly how to split English lavender, when to do it, and how to care for your new divisions so they thrive.
 
Let’s dig into the world of lavender splitting and get your garden ready for more of that amazing fragrance.
 

Why You Can Split English Lavender

You can split English lavender because it responds well to division when done at the right time and with the right method.
 
Unlike some other woody perennials that resent root disturbance, English lavender has a fibrous root system that handles splitting surprisingly well.
 
Here’s why splitting English lavender works and what you need to know before you grab your spade.
 

1. English Lavender’s Growth Habit Makes Splitting Possible

English lavender grows as a woody-based perennial with multiple stems emerging from a central crown.
 
As the plant ages, the center often becomes woody and sparse while the outer sections remain vigorous and green.
 
When you split English lavender, you’re essentially separating those younger, healthier outer portions from the old, tired center.
 
These younger sections have plenty of roots and shoots, which means they’re primed to grow independently once you split English lavender into new plants.
 

2. Splitting Rejuvenates Older Lavender Plants

If your English lavender looks straggly, has a bare middle, or just isn’t flowering as well as it used to, splitting is your answer.
 
When you split English lavender, you remove the dead wood and encourage fresh growth from the roots.
 
This process effectively gives the plant a fresh start, making your lavender splitting efforts worthwhile for garden health.
 

3. Splitting Is a Free Way to Multiply Your Lavender

Instead of buying new plants, you can split English lavender to create multiple new plants from one parent.
 
Each division you take can become a mature lavender bush within a season or two.
 
So not only can you split English lavender for maintenance, but you can also expand your lavender hedge or share divisions with friends.
 

When You Should Split English Lavender

Timing is everything when you decide to split English lavender.
 
Getting this wrong can stress the plant too much, but getting it right gives you strong, healthy divisions.
 
Here’s the best schedule for splitting lavender in most climates.
 

1. Early Spring Is Prime Time for Splitting Lavender

The absolute best time to split English lavender is in early spring, just as new growth starts to appear at the base.
 
This timing allows the divided plants to establish roots before the heat of summer arrives.
 
When you split English lavender in spring, the cooler, moist conditions help the transplants recover without wilting.
 

2. Early Fall is Your Second Window for Splitting Lavender

If you missed the spring window, you can split English lavender in early fall, about six weeks before the first hard frost.
 
This gives the divisions time to root in before winter dormancy sets in.
 
Splitting English lavender in fall works best in milder climates where winters aren’t too severe.
 

3. Avoid Splitting Lavender During Active Bloom or Heat Waves

Never split English lavender during the peak of summer or when the plant is in full bloom.
 
The stress of dividing while the plant is pushing flowers or coping with high heat can be fatal.
 
If you must split English lavender during these times, you’ll need to shade the divisions and water them religiously.
 

How to Split English Lavender Step by Step

Now that you know you can split English lavender and when to do it, let’s walk through the actual process.
 
Following these steps keeps your lavender splitting successful from start to finish.
 

1. Prepare the Plant Before You Split Lavender

Water your English lavender thoroughly a day or two before you plan to split it.
 
Hydrated plants handle root disturbance much better than dry ones.
 
Also, trim back the top growth by about one-third to reduce water loss after you split English lavender.
 
This tip is crucial because fewer leaves mean the roots don’t have to work as hard to support the top.
 

2. Dig Around the Root Ball Carefully

Use a sharp spade or garden fork to dig a circle around the plant, about six to eight inches away from the stems.
 
Lift the entire root ball out of the ground gently.
 
Once it’s out, you can see the natural divisions in the crown, which show you exactly where to split English lavender.
 

3. Divide the Lavender Root Ball Cleanly

You can often pull the root ball apart with your hands, especially on younger plants.
 
For tougher, older roots, use a clean, sharp knife or a spade to cut through the crown.
 
Each section you create should have a good mix of roots and several healthy shoots.
 
This is the heart of splitting English lavender, so take your time and avoid tearing the roots.
 

4. Replant Your Lavender Divisions Immediately

Plant each new division at the same depth it was growing before you split the lavender.
 
Choose a sunny spot with excellent drainage, as lavender hates wet feet.
 
Water the divisions in well after planting, but don’t overwater as this can cause rot.
 
Your freshly split English lavender will appreciate consistent moisture for the first few weeks until new roots form.
 

Care Tips After You Split English Lavender

The work doesn’t end when you split English lavender; proper aftercare is what ensures survival.
 
Here’s how to pamper your new divisions so they settle in nicely.
 

1. Keep the Soil Moist but Not Soggy

In the first month after splitting lavender, water regularly to keep the root zone lightly moist.
 
Once the plants show new growth and establish themselves, taper off watering.
 
Your split English lavender will quickly become drought-tolerant once it roots well.
 

2. Hold Off on Fertilizer

You just split English lavender, so the roots are sensitive, and fertilizer can burn them.
 
Instead of feeding, focus on giving your divisions good light and water.
 
If you want to encourage growth later, apply a light layer of compost around the base in the following spring.
 

3. Protect New Divisions From Harsh Weather

If you split English lavender in early spring and a late frost threatens, cover the new plants with a sheet or cloche.
 
For fall divisions, a layer of mulch around the roots helps insulate them through the winter.
 
Your split English lavender will bounce back quickly in spring with a little protection.
 

So, Can You Split English Lavender?

Yes, you can split English lavender successfully, and it’s a rewarding practice for any gardener.
 
You can split English lavender to revive old plants, multiply your stock, and fill your garden with more of that calming scent.
 
Just remember to split English lavender in early spring or early fall, keep the divisions well-watered but drained, and give them time to establish.
 
With the right care, the lavender you split will reward you with abundant blooms and healthy growth for years to come.
