Can You Split Lavender And Replant

You can absolutely split lavender and replant it to create new plants and keep your garden thriving.

It’s one of the most rewarding tasks for any lavender lover, and honestly, it’s easier than you might think once you understand the plant’s needs.

If you have an overgrown lavender bush that’s looking woody and bare in the middle, splitting it is a fantastic way to rejuvenate it and multiply your supply.

In this post, we’ll walk through exactly why you can split lavender and replant it, the best time to do it, and a step-by-step guide to ensure your new divisions thrive.

Let’s dig in.

Why You Can Split Lavender and Replant It Successfully

The main reason you can split lavender and replant it is because lavender is a woody perennial that responds well to division when done correctly.

But there’s a huge caveat: you can’t just yank any lavender plant apart and expect success.

You can split lavender and replant it only if the plant has a healthy, non-woody base with plenty of new green growth emerging from the crown.

Older lavender plants with thick, entirely brown and brittle woody stems are nearly impossible to divide successfully because they lack the active growth points needed to form new roots.

So, while the answer is a clear yes, the success of your split depends heavily on the age and condition of your plant.

Let’s break down the crucial factors that make splitting lavender a winning strategy.

1. Young Plants Divide Best

The absolute best candidates for division are lavender plants that are around 2 to 3 years old.

At this age, the plant has developed a solid root system but hasn’t become excessively woody at the center.

When you split lavender and replant at this stage, you’re working with vigorous, actively growing sections that recover quickly.

Older specimens, say 5 years plus, often have a large, woody crown that is tough to cut through and doesn’t produce new roots easily.

For those, taking cuttings is a much better propagation method.

2. Look for Natural Divisions

When you dig up your lavender, you’ll often notice it naturally forms clumps with distinct crowns.

You can split lavender and replant these separate crowns easily by gently teasing them apart with your hands or a sharp knife.

These natural separations are perfect because each one already has its own set of roots and shoots.

Splitting along these natural lines minimizes damage and gives each new plant the best possible start.

3. Timing Is Everything

The best time to split lavender and replant it is in early spring, just as new growth begins to appear.

This gives the divided plants the entire growing season to establish their root systems before the heat of summer or the cold of winter arrives.

You can also divide in early fall in milder climates, but spring is generally the safest and most reliable window.

Splitting during the heat of summer stresses the plants excessively, while dividing during winter dormancy often leads to rot.

Step-by-Step Guide on How to Split Lavender and Replant

Now that you understand the why and when, let’s get into the actual process of division.

Following these steps will give you the highest chance of success when you split lavender and replant it in your garden beds or containers.

1. Prepare the New Home First

Before you even dig up your lavender, have the new planting holes ready.

Lavender hates wet feet, so choose a spot with full sun and excellent drainage.

Amend heavy clay soil with plenty of grit or perlite to improve drainage.

Dig your holes slightly larger than the root balls of your divisions and space them about 18 to 24 inches apart to allow for air circulation.

2. Carefully Lift the Parent Plant

Use a garden fork to gently loosen the soil around the lavender plant.

Start about 6 inches away from the base and work your way around in a circle.

Once you’ve loosened the roots, carefully lift the entire clump out of the ground.

Try to keep as much soil around the roots as possible to minimize shock.

Shake off excess soil so you can clearly see the plant’s structure and natural division points.

3. Split the Root Ball Cleanly

Now comes the main act of splitting the lavender.

Identify the natural sections in the crown, each with its own stems and a portion of roots.

For smaller plants, you may be able to pull these sections apart with your hands.

For larger, tougher clumps, use a sharp, sterilized knife or a spade to cut cleanly through the root ball.

Make sure each division has a good amount of roots attached and at least a few healthy green shoots.

Don’t make the divisions too small, as they’ll struggle to survive.

4. Replant Your Divisions Immediately

Holding the roots of a division, place it in a prepared hole at the same depth it was growing before.

Backfill the hole with soil, gently firming it down to eliminate air pockets.

Water the newly planted lavender thoroughly to help settle the soil.

Then, let the soil dry out slightly before watering again, as lavender prefers drier conditions.

Do not mulch around the base, as this can trap moisture and cause the stems to rot.

Best Practices After You Split Lavender and Replant

Your work isn’t done once you’ve split lavender and replanted it into the ground.

Proper aftercare is critical for helping your new plants recover from the shock of division and establish strong roots.

Here are some essential tips to keep your divisions healthy.

1. Keep the Soil on the Dry Side

It’s a common mistake to overwater lavender after transplanting.

While a good initial watering is necessary, you should then allow the top inch of soil to dry out completely before watering again.

Overly wet soil is the fastest way to kill a newly divided lavender plant through root rot.

Your goal is to keep the roots slightly moist, but never soggy.

2. Hold Off on Fertilizing

Lavender is not a heavy feeder, and it actually prefers poor, lean soil.

Do not fertilize your newly replanted divisions for at least a month.

Applying fertilizer can encourage soft, floppy growth that is more susceptible to disease and cold damage.

Let the plant focus its energy on root development first, and it will reward you with vigorous growth.

3. Provide a Little Temporary Shade

If you’re splitting lavender in early spring and a sudden heatwave hits, your new divisions might stress out.

You can provide some temporary shade for the first week or two using a shade cloth or a strategically placed patio umbrella.

Once you see new growth appearing, you can remove the shade, as this indicates the plant has successfully rooted.

So, Can You Split Lavender and Replant It?

You can split lavender and replant it successfully, but only if you pay attention to the plant’s age and overall health.

The best candidates for division are vigorous, 2 to 3-year-old plants with non-woody growth.

Splitting in the early spring, using clean cuts, and providing proper aftercare are the keys to success.

While it’s not something you can do with every old lavender bush, dividing younger plants is a fantastic, free way to expand your lavender collection.

Hope this guide gives you the confidence to split lavender and replant it with great results.
