Lavender is a hugely popular aromatic herb that is used in baking, beauty products and for its medicinal properties. The plant is commonly seen in gardens around the world and is a simple plant to propagate from cuttings.

If you are growing lavender in your garden and want to propagate more plants, then there are several options. While lavender can be grown from seed, it is recommended to propagate existing lavender from cuttings and these can be either softwood or hardwood cuttings.

The differences between the cuttings include both their timing and how long the cuttings take to root. Seen as both offer quicker and more guaranteed solutions than from harvesting seed from your plants, cuttings should be top of your list if you want to propagate lavender.

How to propagate lavender

William Alexander, Lavender Grower at Castle Farm, claims that, while lavender is a ‘semi-woody’ aromatic herb that can be propagated from cuttings or from seed, cuttings do represent the best way of propagating lavender as it ensures that ‘pure varieties’ of lavender emerge that replicate the parent plant.

Lisa Fontanarosa, co-owner of Jo's Farms, a lavender flower farm in New Mexico, adds that lavender cuttings should be taken from mature plants and then rooted in either water or soil – but she favors soil. 

She adds: ‘The best time to propagate lavender is during mid-late summer during their active growing season and when it's hot and humid outside. We prefer to do this at the end of the harvest which is typically mid to end of July. 

‘If you take the cuttings too late in the summer, or in the fall when the plant is starting to go dormant for the winter, they may not root.’

There are two times to take lavender cuttings, either softwood cuttings in spring or summer as outlined by Lisa, or from hardwood cuttings that are taken from the woody portion of the plant later in the year.

How to take softwood lavender cuttings

Softwood cuttings are taken from the new, soft, green growth that appears on lavender bushes in the spring and early summer. The advantage to softwood cuttings is that they root quickly. You must work quickly when taking softwood cuttings and get them into the soil fast, so have the soil prepared to cut the risk of the cuttings drying out before propagating them. Use a clean and sharp pair of pruning shears for taking cuttings to ensure a clean cut and reduce the risk of disease. 

Lisa Fontanarosa advises that you ‘cut from the base of the stem’ when taking softwood cuttings of lavender and each stem you remove for the cutting should be several inches long, have three-to-five leaf nodes, and with some fresh growth at the top.

  • Your cuttings should be three to four inches long and his year’s growth
  • Shoots should not be flowering, and free from pests and disease
  • Remove these away from the main stem with a thin strip of bark still attached
  • Remove the lower leaves so you have three inches of bare stem
  • Dip the end in rooting hormone and place in pots of compost. One example is the Gardentech Rooting Hormone Powder available at Amazon
  • Water well and cover with a clear bag or plastic lid. You can get pots with humidity domes that are perfect for propagation, such as the MIXC Plant Nursery Pots available at Amazon
  • Place the pot in a warm and shady spot, out of direct sunlight
  • Remove the cover after about a month and, once rooted, cuttings are ready to be potted up or you can plant the lavender out in the yard

How to take hardwood lavender cuttings

Hardwood cuttings are taken during the fall and winter months and William Alexander claims these are ‘more hardy and reliable, however they do take longer to root’. He says: ‘We recommend taking hardwood cuttings in late fall after flowering is complete, and the plant is dormant.’

For hardwood cuttings you want to choose a healthy side shoot and cut below a bump in the older brown wood. Lavender hardwood cuttings will be longer than ones taken for softwood cuttings, and want to be four to six inches in length. These cuttings can be taken at the same time as regular lavender pruning that occurs in fall.

Like with softwood cuttings, strip the lower leaves to leave a bare patch of stem and dip it in rooting powder before inserting into compost. The pot should be put in a well ventilated and shady area, watered sparingly, and then potted up individually when well-rooted. Remember that hardwood cuttings can take four to six weeks to start rooting.

How to propagate lavender in water

It is possible to propagate herbs, including lavender, in water.  The advantage of propagating lavender in water is that the cuttings will start rooting quicker than in soil. However, their survival rates overall may be lower as they do not always respond well when it comes time to transplant the lavender.

Both softwood and hardwood cuttings can be propagated in water, however roots will develop quicker on softwood cuttings. 

To grow lavender indoors in water, fill a glass with around two to three inches of water. Take your lavender cuttings and strip the bottom few inches of the stem of leaves. You do not want any leaves below the water line, or touching the water. Put the stem into the water and place them somewhere light, like on a windowsill, but not in full sun.

The roots should start to form quickly, within two weeks for softwood cuttings but more than double that for hardwood. Keep the water topped up and change the water if it becomes discolored. 

Once the cuttings have developed a good root system, it is time to plant the new young lavender. You can either pot it up to grow on, or plant it straight out in the backyard.

Propagating lavender is a fairly simple task and the best way to grow more aromatic herbs for your herb garden at home. Whether you want to take softwood or hardwood cuttings is up to you, both are viable ways of getting new plants. The other option is to get a packet of lavender seeds, such as from Burpee, but it is a slower way and it will be much longer till you can harvest lavender from those plants.
