If you’ve ever wondered about how to grow lavender from cuttings in water, the good news is that it’s totally doable with just a few simple steps.
 
In this post, we’ll walk through exactly how to grow lavender from cuttings in water, what you need to know about rooting them successfully, and how to transition your new plants into soil.
 
Let’s dive in.
 

How to Grow Lavender from Cuttings in Water

Growing lavender from cuttings in water starts with choosing the right stems and preparing them properly.
 
Here’s a breakdown of the key steps to get it right.
 

1. Choose the Right Cuttings

To grow lavender from cuttings in water, you need healthy, non-flowering stems.
 
Look for softwood cuttings that are green and flexible, not woody and hard.
 
The best time to take cuttings is in the morning when the plant is well-hydrated.
 
Use sharp, clean scissors or pruners to snip a 4 to 6-inch stem just below a leaf node.
 

2. Prepare the Cuttings for Water

Once you have your cuttings, strip the leaves from the bottom two-thirds of each stem.
 
You want to expose a few inches of bare stem so it can take up water efficiently.
 
If there are any flower buds, pinch them off because they divert energy away from root production.
 
This step is crucial when learning how to grow lavender from cuttings in water because it directs the plant’s focus to rooting.
 

3. Place Cuttings in Water

Fill a clean glass or jar with fresh, room-temperature water.
 
Place your prepared cuttings into the water, making sure the stripped nodes are submerged.
 
Keep the leaves above the waterline to prevent rot.
 
You can put several cuttings in one jar, but don’t overcrowd them.
 

4. Provide the Right Conditions

Place the jar in a warm spot with bright, indirect light.
 
Direct sunlight can overheat the water and encourage algae growth.
 
Change the water every few days to keep it fresh and oxygenated.
 
This simple habit is one of the most overlooked tips for how to grow lavender from cuttings in water.
 

5. Wait for Roots to Develop

Roots typically start appearing within two to four weeks.
 
You’ll see small white nubs forming along the submerged stem.
 
Be patient—some cuttings take longer depending on the variety and conditions.
 
Once the roots are about an inch long, your cuttings are ready for the next stage.
 

Tips for Successfully Rooting Lavender Cuttings in Water

Getting lavender cuttings to root in water isn’t complicated, but a few smart habits make a big difference.
 
Here’s what to keep in mind.
 

1. Use a Rooting Hormone (Optional)

While lavender will root in water without any help, dipping the cut end in rooting hormone can speed things up.
 
It’s not necessary, but it can improve your success rate, especially with stubborn varieties.
 

2. Avoid Direct Sunlight

Bright, indirect light is ideal.
 
Too much direct sun can wilt the cuttings or cause the water to heat up too quickly.
 
A windowsill that gets gentle morning light works beautifully.
 

3. Keep the Water Clean

Cloudy or slimy water is a sign that bacteria are building up.
 
Change the water every two to three days to prevent rot and keep the stems healthy.
 

4. Be Patient with Woody Stems

Softwood cuttings root fastest, but if you’re working with semi-woody stems, expect a longer wait.
 
They can still grow lavender from cuttings in water, but they may take four to six weeks.
 

5. Pot Them Up at the Right Time

Once roots are one to two inches long, it’s time to transfer your cuttings to soil.
 
Use a well-draining potting mix and a small pot with drainage holes.
 
Water gently and keep the soil slightly moist as the roots adjust.
 

Common Mistakes When Growing Lavender Cuttings in Water

Even though growing lavender from cuttings in water is simple, a few missteps can trip you up.
 
Watch out for these common issues.
 

1. Letting Leaves Sit in Water

Leaves that stay submerged will rot quickly and foul the water.
 
Always strip the lower leaves before placing cuttings in the jar.
 

2. Skipping Water Changes

Stagnant water loses oxygen and breeds bacteria.
 
Fresh water every few days keeps everything healthy and speeds up rooting.
 

3. Using the Wrong Cuttings

Hard, woody stems are much slower to root than soft, green ones.
 
For the best results when you grow lavender from cuttings in water, stick with softwood cuttings.
 

4. Moving Them to Soil Too Soon

If roots are still tiny, they won’t survive the transition.
 
Wait until they’re at least an inch long before potting up.
 

5. Overwatering After Potting

Lavender hates soggy soil.
 
Once your rooted cuttings are in pots, let the soil dry out slightly between waterings.
 

So, Can You Grow Lavender from Cuttings in Water?

You can absolutely grow lavender from cuttings in water, and it’s a rewarding project that saves you money and gives you new plants to enjoy.
 
Just remember to take softwood cuttings, keep the water fresh, and be patient while roots develop.
 
Once they’re rooted, pot them up in well-draining soil and watch them thrive.
 
Now you know exactly how to grow lavender from cuttings in water, so grab your snips and give it a try.
