Lavender multiplies primarily through seed propagation, layering, or stem cuttings. However, stem cuttings and layering are the most recommended methods to ensure the new plants are true to type and not hybrids resulting from cross-pollination.
Here's a breakdown of each method:
-
Seed Propagation:
- Lavender can be grown from seed, but this method can be less predictable.
- Seeds may require stratification (a period of cold) to germinate.
- The resulting plants may not be identical to the parent plant if cross-pollination has occurred.
-
Layering:
- Layering involves bending a low-growing stem to the ground and covering a portion of it with soil.
- The buried section will develop roots while still attached to the parent plant.
- Once roots have formed, the new plant can be severed and transplanted.
- This method is relatively easy and produces a clone of the parent plant.
-
Stem Cuttings:
- Stem cuttings involve taking a cutting from a healthy lavender plant and rooting it in a suitable medium.
- Cuttings can be taken from softwood (new growth) or hardwood (mature growth).
- The cuttings are typically treated with a rooting hormone to encourage root development.
- This method is widely used and provides genetically identical plants.
In summary, while lavender can be multiplied by seed, layering, or stem cuttings, the latter two methods are preferred for maintaining the specific characteristics of the parent plant and avoiding potential hybrid variations.
