Can Lavender Be Split

Yes, lavender can be split easily, and doing so is one of the best ways to keep your plants healthy and vigorous.

If you’ve ever wondered whether you can split lavender to make more plants or simply to rejuvenate an older, woody specimen, you’ll be happy to know that it’s a straightforward process.

You can split lavender, but the timing and method are key because lavender has a unique root system that responds best to gentle handling.

In this post, we’ll explore exactly how you can split lavender, when you should do it, and what steps you need to take to ensure your divided plants thrive.

So let’s dig in and get your garden full of these fragrant, beautiful shrubs.

 

Can Lavender Be Split Successfully?

You can split lavender successfully, but there are a few important details to understand first.

Unlike many perennials that can be ripped apart with a shovel, lavender requires a more refined touch due to its woody base and sensitive root structure.

You can split lavender to propagate new plants, but you should focus on younger plants because older lavender often becomes too woody to divide successfully.

When you split lavender that is still green and supple at the base, you have a much higher chance of each new section rooting and growing well.

 

1. Why Splitting Lavender Works Best on Young Plants

You can split lavender that is between two and three years old with great success.

Younger lavender plants have flexible stems and a fibrous root system that handles division without going into shock.

You can split lavender every few years to prevent it from becoming leggy and to maintain that compact, bushy shape we all love.

Once lavender reaches four years or older, the center of the plant often becomes dry, cracked, and completely woody.

Splitting this old growth rarely works, and you might end up with sections that simply won’t root.

 

2. The Best Season to Split Lavender

You can split lavender in early spring or early autumn, but timing does make a difference.

Splitting lavender in the spring, just as new green growth emerges, gives your divisions the entire growing season to establish themselves.

You can split lavender in the fall as well, but you need to allow at least six weeks before the first hard frost.

This gives the new roots enough time to anchor into the soil before winter dormancy.

Avoid splitting lavender during the peak of summer heat because the stress of transplanting can be too much for the plant to handle.

 

Steps to Split Lavender the Right Way

If you want to know exactly how you can split lavender without damaging the parent plant, follow these simple, gardener-friendly steps.

You can split lavender with nothing more than a sharp spade, a clean knife, and some quality potting mix.

Let’s walk through the process so you can split lavender with total confidence.

 

1. Prepare the Ground Before You Split Lavender

Before you split lavender, water the plant thoroughly a day in advance.

Moist soil helps the roots hold together better and reduces the shock of division.

You can split lavender more easily when the root ball is slightly damp rather than bone dry or soaking wet.

Gather your tools and have new planting holes ready before you lift the plant out of the ground.

This minimizes the time the roots spend exposed to the air.

 

2. Lift the Plant Gently

To split lavender, start by digging around the base of the plant to loosen the soil.

Insert your spade at a 45-degree angle and work your way around the entire root ball.

You can split lavender by lifting the entire plant out of the ground once you’ve loosened the soil all around.

Gently shake off excess soil so you can see the natural crown and root structure clearly.

You’ll often find that the plant has already formed natural divisions that you can use to split lavender cleanly.

 

3. Divide the Root Ball Carefully

Now it’s time to actually split lavender.

Use a sharp, clean knife or a pair of pruning shears to cut through the root ball.

You can split lavender into two, three, or even four sections as long as each section has a healthy amount of roots and several green shoots.

Try to avoid tearing the roots because ragged cuts invite disease and rotting.

Each divided piece should be about the size of a large fist to give it the best chance of survival.

 

4. Replant Your Lavender Divisions Immediately

You can split lavender, but we always recommend replanting the divisions right away.

Place each new section into a prepared hole that is just slightly larger than the root ball.

Backfill with a well-draining soil mix that has some sand or grit mixed in.

Lavender hates wet feet, so drainage is absolutely critical after you split lavender.

Water your new plants in well, but then let the soil dry out completely before watering again.

 

Common Mistakes When You Split Lavender

You can split lavender successfully, but only if you avoid a few common pitfalls that lead to failure.

Let’s look at the biggest mistakes gardeners make when they split lavender so you can sidestep them.

 

1. Splitting Lavender Too Late in the Season

You can split lavender in the spring, but if you do it too late in the fall, your plants won’t have time to recover.

Late divisions often freeze out over the winter.

Timing your split lavender project just right is more important than any other single factor.

 

2. Overwatering After You Split Lavender

Many gardeners panic after they split lavender and water too frequently.

Lavender actually prefers dry, poor soil, and overwatering after division is the number one killer.

You can split lavender perfectly, but if those new roots sit in soggy ground, they will rot.

Instead, water deeply but infrequently to encourage deep root growth.

 

3. Splitting Old Woody Lavender

As we mentioned earlier, you can split lavender that is too old, but the success rate drops dramatically.

If your lavender is more than four or five years old and woody at the center, it’s often better to take cuttings instead.

You can split lavender for propagation, but young, green, semi-ripe cuttings actually root much more reliably than woody old divisions.

 

So, Can Lavender Be Split or Not?

Yes, lavender can be split, and you can split lavender to increase your stock or renovate an overgrown plant.

You can split lavender successfully as long as you do it at the right time and on plants that still have plenty of green growth.

You can split lavender into several healthy new plants by lifting the entire root ball, dividing it gently, and replanting immediately.

The secret is to keep the roots moist but not wet, plant in gritty, free-draining soil, and give them plenty of sunshine.

Splitting lavender is a rewarding and cost-effective way to fill your garden with more of these wonderful aromatic plants.
