Why would you want more lavender? Well, why wouldn’t you! It has the most delightful scent that is beloved in aromatherapy. It is known for its relaxing and calming properties, helping to ease stress and insomnia.
Beyond aromatherapy, it also has a delicate floral taste that I adore in cooking. Believe it or not, some people propagate lavender just for culinary purposes.

Expert Tips for Propagating Lavender
- Only take cuttings from healthy softwood stems. Softwood stems are new growth that is lighter in colour and more flexible than older hardwood stems.
- Take cuttings with no flowers or buds on them, typically during mid-summer when the plant is actively growing.
- Immediately place the cutting in a moist paper towel or water until you can plant it.
- Remove the bottom two inches of leaves, then place either in soil 2 inches deep or in water. Lavender will grow easily in water, but the transplant rate is lower than those grown in soil.
- Keep the cutting moist and place it somewhere warm and out of direct sunlight.
How to Propagate Lavender from Cuttings
If you want lavender, you can easily get a whole garden full of the herb from a single plant. The best way to propagate lavender is by taking stem cuttings. The first step to getting a successful lavender cutting is by making the right selection.
To get the best yield possible, you want only to select cuttings from a healthy part of the plant, free of pests and diseases. I like to choose side shoots from areas with lots of foliage so they won’t be missed.
On the lavender plant, you will see softwood and hardwood. You want to trim softwood only. It is lighter in colour and more flexible than hardwood. This is the newer growth, and it will root easier.
Take Your Cutting
Grab a sharp knife, disinfect it with soapy water, and then with rubbing alcohol. Cut a softwood stem with no flowers or buds on it. The cutting should be 3-4 inches long.
Once you have your cutting, immediately wrap it in a moist paper towel or place it in a bucket or cup of water. Keep your lavender cutting cool until you are ready to plant it. Ideally, you should plant this cutting within 24 hours after taking it.
Plant Your Lavender Cutting
When you’re ready to plant your cutting in soil, remove all the leaves from the bottom two inches of the stem. You will also want to scrape the skin off the stem on one side of the bottom two inches.
You can place your cutting directly in the soil or dip it in a rooting hormone like willow water first. However, lavender does root quite easily, so don’t worry if you don’t have any rooting hormone on hand.
Poke your finger, a chopstick, or a pencil in the soil two inches deep. Place your stem in and pack the surrounding soil so the plant is standing straight up.
Lavender Cutting Care
To make a mini-greenhouse for your lavender cutting, carefully place a zip-top bag over the cutting. Place your cutting in a warm area that is out of direct sunlight. Keep the cutting moist, but release condensation from the bag every few days so the leaves don’t get soggy.
Once there is new growth, remove the bag and reduce humidity. Let the soil dry completely between watering. You can also begin to fertilize the cutting at this stage to encourage quicker growth.
Once there are full, new leaves, your lavender is ready for transplant. Take it to its new permanent home!
Frequently Asked Questions About Propagating Lavender
In my lavender propagation instructions, you probably noticed I mentioned placing the cutting directly in the soil. However, this is not the only way to root a lavender cutting.
Lavender will actually take easier to water propagation. BUT, the success rate for transplanting the cutting will be much lower. So, if you want to try propagating lavender with water, keep this in mind!
Once your lavender cutting has significant roots, about an inch long, you can put your cuttings in soil.
The best time of year to propagate lavender is during its active growth season and when the plant is not currently flowering. If you take your cutting too late in the summer or fall, it may not root as the plant could be dormant.
Snip your cuttings in the morning when the air is nice and cool. This way, your lavender plants aren’t under any further stress from heat.
Lavender cuttings should be taken during the active growth season between flowerings. This typically falls between July and August.
Patience is hard when it comes to propagating lavender! Luckily, lavender roots quite easily. You can expect to wait two to four weeks for softwood cuttings to take root.
Older hardwood cuttings will take much longer. I usually avoid snipping or pruning hardwood on a lavender plant unless it gets very unruly.
Place your lavender cutting outside of direct sunlight, as the cuttings are delicate and could burn with too much sun. Absolutely ensure it’s protected from the afternoon sun. However, you want it to stay warm, so south-facing windows are great options.
