The best time to propagate a lavender is spring or summer. However, you should cut the lavender cuttings no later than the end of July, as they need at least six weeks to take root. On the other hand, cuttings should be placed only in the spring, as they can be separated from the mother plant no earlier than three months.
Propagate lavender with cuttings
Lavender is quite easy to propagate via cuttings. In many cases, it’s better to take cuttings from an old, woody lavender bush and then either cut the mother plant back properly – “rejuvenate” as the gardener says – or take it out altogether. For the cuttings propagation itself, proceed as follows:
- Select young, not-yet-woody shoots with at least two leaf attachments.
- These should be between 10 and 15 centimeters long.
- Already woody cuttings are also suitable, but need longer to root.
- Cut with a clean and sharp knife, not scissors.
- The cut surface should be slanted so that the shoot can absorb water more easily.
- Dip the cut surface in a rooting hormone (powder).
- Plant the cuttings individually in small pots with nutrient-poor soil (growing soil).
- Water them thoroughly.
- Finally, water only, – when the substrate has already dried.
- Place the pot warm and so- nnig – but not yet in full sun.
- After about six to eight weeks you can transplant the seedling.
Propagate lavender via cuttings
Instead of cutting the cuttings, you can also grow them as so-called cuttings. For this purpose, the cuttings do not need to be cut off, but can remain on the mother plant until they themselves have developed roots.
- Select a flexible, young branch.
- This should be as close to the ground as possible.
- Dig a hole about 10 to 15 inches deep a short distance away.
- Bury the branch center there, with the leaves and flowers peeking out on the other side.
- Weigh the branch down with a rock or similar so that it does not slip out.
- Water the buried branch regularly.
- After about three to four months, the sapling should have developed its own roots and can be separated from the mother plant.
Tips & Tricks
Sometimes you will find the advice to divide large lavender bushes for the purpose of propagation. However, this is hardly possible with lavender, after all, they are not perennials, but shrubs that become woody with age.
