Lavender can be propagated through several methods, including seeds, cuttings, and layering. Here are the steps for each propagation method:
- Propagation from Seeds:
- Collect mature lavender seeds from dried flower heads or purchase high-quality seeds from a reputable source.
- Start seeds indoors about 6-10 weeks before the last frost date or sow them directly in the garden after the danger of frost has passed.
- Prepare a seed-starting tray or small pots with a well-draining seed starting mix.
- Sow the lavender seeds on the surface of the soil and lightly press them down. Do not cover them with soil, as lavender seeds require light for germination.
- Mist the soil with water to keep it consistently moist but not waterlogged.
- Place the tray or pots in a warm location with indirect sunlight.
- Germination can take 2-4 weeks. Once the seedlings develop a few sets of true leaves, they can be transplanted into larger containers or moved to the garden.
- Propagation from Cuttings:
- Take lavender cuttings in the spring or early summer when the plants are actively growing.
- Select healthy, non-flowering stems and cut 4-6 inches (10-15 cm) long cuttings just below a leaf node.
- Remove the leaves from the lower portion of the cutting, leaving a few leaves at the top.
- Dip the cut end of the stem in a rooting hormone to promote root development (optional).
- Plant the cuttings in a well-draining potting mix or a mixture of perlite and vermiculite.
- Place the pot or tray in a warm, bright location with indirect sunlight.
- Mist the cuttings regularly to keep the soil moist but not saturated.
- After a few weeks, the cuttings should develop roots. Once the roots are well-established, they can be transplanted into individual pots or directly into the garden.
- Propagation by Layering:
- Choose a low-growing, flexible lavender branch that can be bent to the ground without breaking.
- Prepare the area where the branch will touch the ground by removing any grass or weeds and loosening the soil.
- Make a shallow cut or scrape on the underside of the branch where it will come into contact with the soil.
- Secure the cut portion of the branch into the soil using a U-shaped garden staple or a small rock.
- Cover the branch with soil, leaving the tip exposed above the ground.
- Water the layered branch regularly to keep the soil moist.
- After a few weeks or months, the layered branch should develop roots. Once the roots are established, the branch can be cut from the parent plant and transplanted.
Regardless of the propagation method you choose, it’s essential to provide the newly propagated lavender plants with appropriate care, including proper watering, sunlight, and protection from extreme temperatures until they become established.
