You can grow lavender from an existing plant by taking cuttings from healthy stems and rooting them in soil or water.
This is one of the easiest and most rewarding ways to multiply your lavender without buying new plants every season.
If you’ve ever wondered how to grow lavender from an existing plant, the good news is that it’s totally doable even if you’re a beginner.
Whether you want to fill your garden with more of that lovely purple bloom or share cuttings with friends, propagating lavender from an existing plant is a skill worth learning.
In this post, we’ll walk through exactly how to grow lavender from an existing plant, the best time to take cuttings, and the simple steps to get them rooting successfully.
Why You Can Grow Lavender From an Existing Plant
You can absolutely grow lavender from an existing plant, and here’s why it works so well:
1. Lavender Roots Easily From Cuttings
The main reason you can grow lavender from an existing plant is that lavender is a fantastic candidate for stem cuttings.
Unlike some plants that are stubborn about rooting, lavender produces new roots fairly reliably when you take a cutting the right way.
This means you can snip a stem from a plant you already have and turn it into a whole new lavender bush.
2. You Get an Exact Clone of the Parent Plant
When you grow lavender from an existing plant through cuttings, you’re essentially making a clone.
The new plant will have the same fragrance, flower color, and growth habits as the parent plant you took the cutting from.
That’s a big deal if you have a lavender variety you absolutely love and want more of.
Growing lavender from seed can give you unpredictable results, but growing lavender from an existing plant keeps things consistent.
3. It Saves You Money and Time
Buying new lavender plants every year adds up quickly.
When you learn how to grow lavender from an existing plant, you can expand your garden for free.
Plus, cuttings from an established plant tend to grow faster than seedlings because they start with more maturity.
4. You Can Do It Almost Any Time of Year
While there are ideal seasons for taking lavender cuttings, you can grow lavender from an existing plant indoors during cooler months too.
As long as you provide warmth and light, your cuttings have a solid chance of rooting.
How to Grow Lavender From an Existing Plant Step by Step
Now let’s get into the actual process of how to grow lavender from an existing plant so you can get it right the first time.
1. Choose the Right Time to Take Cuttings
The best time to grow lavender from an existing plant is in early spring or early fall.
During these periods, the plant is actively growing but not stressed by extreme heat or cold.
Avoid taking cuttings during the peak of summer or the dead of winter.
2. Pick a Healthy Stem
Look for a stem that’s green, flexible, and free of flowers or buds.
Softwood cuttings from the current year’s growth root the fastest when you grow lavender from an existing plant.
Use clean, sharp scissors or pruning shears to cut just below a leaf node.
3. Strip the Lower Leaves
Remove the leaves from the bottom two to three inches of the cutting.
This exposed section is where roots will form when you grow lavender from an existing plant.
Leaving leaves buried in soil can cause rot, so keep that area clean.
4. Dip the Cutting in Rooting Hormone
While lavender can root without it, dipping the cut end in rooting hormone boosts your success rate.
It’s a small step that makes a big difference when you grow lavender from an existing plant.
5. Plant in Well-Draining Soil
Lavender hates soggy roots, so use a mix of potting soil and perlite or sand.
Stick the cutting about two inches deep into the soil.
Water lightly and keep the soil barely moist, not wet.
6. Provide Warmth and Indirect Light
Place your cuttings in a warm spot with bright, indirect light.
A windowsill or a shaded greenhouse works great.
If you grow lavender from an existing plant indoors, avoid direct afternoon sun which can dry out the cuttings.
7. Be Patient and Wait for Roots
It usually takes three to six weeks for roots to develop.
You’ll know roots have formed when you see new growth or feel resistance when you gently tug the cutting.
Common Mistakes to Avoid When Growing Lavender From an Existing Plant
Even though it’s simple, a few missteps can ruin your chances when you grow lavender from an existing plant.
1. Overwatering
The number one killer of lavender cuttings is too much water.
Keep the soil slightly moist but never soaked.
2. Taking Cuttings From Flowering Stems
Flowering stems put energy into blooms, not roots.
Always choose non-flowering stems when you grow lavender from an existing plant.
3. Using Dirty Tools
Clean your scissors with rubbing alcohol before cutting.
Dirty tools introduce bacteria that can rot your cuttings before they root.
4. Skipping the Hardening Off Process
Once roots form, gradually introduce your new plant to outdoor conditions.
This step is easy to forget when you grow lavender from an existing plant, but it prevents shock.
So, How Do You Grow Lavender From an Existing Plant?
You grow lavender from an existing plant by taking healthy stem cuttings and rooting them in well-draining soil with warmth and indirect light.
It’s a straightforward process that saves money and gives you exact copies of your favorite lavender.
Just remember to take cuttings at the right time, avoid overwatering, and be patient while roots develop.
Once you master how to grow lavender from an existing plant, you’ll never need to buy lavender again.
