Lavender Plant FAQ’s

Should I Deadhead Lavender?

Lavender should be deadheaded to promote further growth of new flowers. Lavender responds well to deadheading and doing so assists in maintaining the plant.

To deadhead lavender, simply wait until new growth appears, then cut the dead stems down to just above the green leaves. Cutting down to leafless wood will deter the plant from re-blooming. This can be done every year after the plant reaches maturity in its first year of growth.

“Timely pruning helps lavender stay compact and well-kept, and it optimizes flower production. Prune it once in the spring when the new growth appears—prune off dead stems down to the first set of green leaves. Lavender can also be pruned after it flowers to help keep it compact and it will possibly bloom a second time—prune off one-third to one-half of the plant. When pruning, do not cut down to the leafless wood, as it will not regrow.”

Is Lavender an Annual or Perennial?

Lavender is a bushy perennial but in some climates, is grown as an annual. In hot and dry regions lavender can stay green, vibrant, and flowering throughout most of the year.

Varieties of English lavender are the most cold hardy growing as far north as zone 3. Spanish and French variants of lavender are not cold hardy enough to survive as perennials in Colorado.

Commercially lavender is a promising annual grown as a cash crop. Specifically, lavender is grown annually and used as a primary cash crop in New Mexico, Texas, and Washington State.

How Fast Does Lavender Grow?

Lavender tends to grow rather slowly and it takes 2-3 years depending on growing region and variety being grown for the plants to reach full size.

After sowing seeds directly into the ground, lavender takes approximately one to three months to germinate according to Cornell University.

If seeds are stratified, stored in temperatures of around 35 degrees for 3-4 weeks, then germination can happen faster, in about two weeks.

How Long Does Lavender Bloom For?

Lavender blooms in the summer months, usually from mid-June to July. Depending on the species of lavender and the season in which it is planted, blooming will typically last 4-8 weeks.

It Is suggested that lavender be planted near an open window, with the breeze bringing in the smell, allowing gardeners to enjoy the delightful aroma the herb offers while indoors.

Does Lavender Multiply?

Woody plants—which lavender is considered to be—propagate naturally with careful assistance. When longer branches grow closely to the soil’s surface, the roots then touch down and begin the growth of new, smaller plants. This method is called layering.

Once the already existing plants have rooted into the soil, new plants will begin to form. The new plants can be carefully transferred into individual pots or replanted into different soil to promote further growth multiplying of new lavender plants.

You can expedite and increase the efficiency of this process by taking cuttings and rooting them as clones.

How To Grow Lavender From Cuttings

Due to the slowness of lavender seed germination, many lavender plants are propagated from cuttings harvested in the summer. These cuttings are usually taken from side shoots of the best producing plants.

To begin new plants, take the fresh cuttings and sow them into the soil. Sterile soil like fresh potting soil is best for this process but it will likely be no problem in garden soil.

Place the cuttings three to four inches apart. When the seedlings grow large enough, transplant them 18 to 24 inches apart in dry soil, well after the last frost.

Cuttings from stems can be taken off the plant at any point during the peak season. The leaf should be cut just above where it meets the stem. Cuttings require bright light, but not necessarily direct sun, and soil should be kept moist.

Another option for reproducing lavender is layering, which can be done by placing lavender’s branches into the soil to stimulate new root growth.

How Much Sun Does Lavender Need?

Lavender is a plant that requires full sun and will not flower if set in partial shade. Lavender demands at least 6 hours of full sun and optimally 8-10 hours and to be planted in well draining soil. If the plant fails to receive either of these, it will result in a stressed and less than optimal plant.

However, it should be noted that these hours do not need to be continuous, and can happen at varying points throughout the day. To encourage the absorption of sunlight, lavender can be planted in light-colored mulch, such as straw or white rock, to reflect the sunlight up towards the lavender.

Additionally, full sun for lavender plants is important because it directly increases the growth of the flower and the fragrant aroma of the herb.
