How To Grow Lavender From Existing Plant

You can grow lavender from an existing plant, and it’s actually one of the easiest ways to expand your lavender collection without spending a dime.
 
If you’ve ever wondered how to grow lavender from existing plant cuttings, the answer is simpler than you might think.
 
Lavender is a hardy herb that roots well from softwood cuttings, and with a little patience, you’ll have new plants ready to thrive in your garden.
 
The best part is you can take cuttings from a healthy lavender plant you already own and turn those clippings into brand-new lavender plants.
 
In this post, we’ll walk through exactly how to grow lavender from an existing plant step by step, so you can enjoy more of that gorgeous fragrance and color.
 
Let’s dive in.
 

Why You Can Grow Lavender From an Existing Plant

Growing lavender from an existing plant works because lavender naturally propagates through cuttings.
 
Here’s why this method is so reliable:
 

1. Lavender Roots Easily From Cuttings

Lavender is a semi-woody perennial that responds well to propagation from stem cuttings.
 
When you take a cutting from an existing lavender plant, you’re essentially cloning that plant.
 
This means your new lavender will have the exact same scent, color, and growth habits as the parent plant.
 
That’s a huge advantage over growing lavender from seed, which can be unpredictable.
 

2. It Saves You Money

If you already have a lavender plant you love, why buy more?
 
Learning how to grow lavender from an existing plant means you can multiply your plants for free.
 
You can fill garden beds, create borders, or share lavender with friends.
 
All it takes is a sharp pair of scissors and a little know-how.
 

3. You Preserve Your Favorite Variety

When you grow lavender from an existing plant, you keep the exact genetics of that plant.
 
If your lavender has a particularly strong fragrance or a beautiful bloom color, cuttings let you replicate it.
 
This is especially valuable with named lavender varieties like ‘Hidcote’ or ‘Munstead’.
 
Growing lavender from existing plant cuttings ensures you get more of what you already love.
 

How to Grow Lavender From an Existing Plant: Step by Step

Now let’s get into the actual process of growing lavender from an existing plant.
 
Follow these steps for the best results:
 

1. Choose the Right Time to Take Cuttings

The best time to grow lavender from an existing plant is in late spring or early summer.
 
This is when the plant is actively growing and softwood cuttings root most easily.
 
Early morning is ideal because the plant is well-hydrated.
 
Avoid taking cuttings when lavender is in full bloom, as the plant’s energy is focused on flowers.
 

2. Select Healthy Stems

Look for stems that are green and flexible but not too soft.
 
A good cutting stem should be about 4 to 6 inches long.
 
Make sure the stem has no flowers or buds.
 
Choose stems from the current season’s growth for the best rooting success when growing lavender from an existing plant.
 

3. Cut Just Below a Leaf Node

Using clean, sharp scissors or pruners, cut just below a leaf node.
 
The leaf node is where roots are most likely to form.
 
Strip the lower leaves from the bottom two inches of the cutting.
 
This bare section is where you’ll plant the cutting into the rooting medium.
 

4. Dip the Cutting in Rooting Hormone

While lavender can root without hormone, dipping the cut end in rooting hormone speeds things up.
 
It also increases your chances of success when growing lavender from an existing plant.
 
You can use a powdered or gel rooting hormone available at garden centers.
 
If you prefer organic methods, raw honey works as a natural rooting aid.
 

5. Plant the Cutting in Well-Draining Soil

Lavender hates soggy roots, so drainage is crucial.
 
Use a mix of potting soil, perlite, and coarse sand.
 
Plant the cutting about two inches deep into the soil.
 
Firm the soil gently around the stem to hold it upright.
 

6. Create a Humid Environment

To grow lavender from an existing plant successfully, you need to keep humidity high while roots form.
 
Cover the pot with a clear plastic bag or place it in a propagator.
 
Make sure the plastic doesn’t touch the leaves.
 
Open the bag for a few minutes every day to prevent mold.
 

7. Provide Indirect Light and Warmth

Place your cuttings in a bright spot away from direct sunlight.
 
Too much sun can dry them out before roots develop.
 
A windowsill with filtered light or a shaded greenhouse works perfectly.
 
Keep temperatures around 65 to 75°F for optimal rooting.
 

8. Wait for Roots to Develop

Roots typically form within three to six weeks when growing lavender from an existing plant.
 
You’ll know roots have formed when you see new growth or feel resistance when you gently tug the cutting.
 
Once roots are established, remove the plastic cover.
 
Let the young plant acclimate for a few days before transplanting.
 

Common Mistakes to Avoid When Growing Lavender From an Existing Plant

Even though growing lavender from an existing plant is straightforward, a few mistakes can trip you up.
 
Here’s what to watch out for:
 

1. Overwatering

Lavender is drought-tolerant and hates wet feet.
 
Water cuttings sparingly, only when the soil feels dry.
 
Too much moisture leads to rot and kills your cuttings fast.
 

2. Using Woody Stems

Old, woody stems root poorly.
 
Always choose soft, green growth for the best results.
 
If the stem snaps easily, it’s too woody.
 

3. Skipping Drainage

Poor drainage is a death sentence for lavender cuttings.
 
Always use a pot with drainage holes and a gritty soil mix.
 
Never let cuttings sit in standing water.
 

So, How Do You Grow Lavender From an Existing Plant?

You can grow lavender from an existing plant by taking softwood cuttings in late spring or early summer, stripping the lower leaves, dipping the cut end in rooting hormone, and planting it in well-draining soil.
 
With warmth, indirect light, and a little humidity, your cuttings will root within a few weeks.
 
Growing lavender from an existing plant is rewarding, free, and surprisingly easy once you know the steps.
 
So grab those scissors, take a few cuttings, and watch your lavender garden multiply.
