Growing lavender from a tiny seed or small cutting into a robust, aromatic shrub is a rewarding experience. This initial growth phase, nurturing “lavender baby plants,” establishes the foundation for a healthy mature plant.
How to Start Lavender Baby Plants
Starting lavender can be achieved through either seeds or cuttings. When propagating from seed, lavender seeds often benefit from cold stratification, a process that mimics winter conditions and encourages germination. This involves placing seeds in a damp medium, like sand or a paper towel, and refrigerating them for three to four weeks before sowing.
Once stratified, sow the tiny seeds shallowly, about 1/8 inch deep, in a sterile, well-draining seed-starting mix. Optimal germination occurs around 70°F (21°C) and requires light. For propagation via cuttings, select healthy, non-flowering stems, 4-6 inches long, from a mature plant. Remove the lower leaves and consider dipping the cut end in rooting hormone. Plant these prepared cuttings into a well-draining rooting medium, such as a mix of perlite and potting soil.
Nurturing Young Lavender Plants
Once lavender seeds have germinated or cuttings have rooted, provide the right environment for their continued development. Young lavender plants require abundant light, ideally 12-16 hours daily, achievable with grow lights or a bright, south-facing window. Consistent light prevents legginess. Maintain consistent moisture, ensuring the soil is moist but never waterlogged, as young lavender is susceptible to root rot. Allow the top inch of soil to dry slightly between waterings.
Ensure good air circulation around seedlings to prevent fungal issues; a gentle fan can help indoors. Young lavender plants generally do not require significant fertilization. If needed, use a very dilute, balanced liquid fertilizer.
Transplanting and Establishing Lavender
Seedlings are ready for transplanting when they have developed several sets of true leaves or roots emerge from their pots, typically 4-6 weeks after germination. Harden off plants by gradually exposing them to outdoor conditions—sunlight, wind, and fluctuating temperatures—for one to two weeks to reduce transplant shock.
Choosing the right garden location is important for lavender. Lavender thrives in full sun, requiring at least six hours of direct sunlight daily. Prepare a well-draining planting site, ideally with a sandy or gravelly loam texture and a slightly alkaline to neutral pH (6.5-7.5). If soil is heavy clay, amend it with grit, sand, or small stones to improve drainage, or use raised beds.
Plant lavender at the same depth it was in its nursery pot, ensuring the crown is not buried, and space plants adequately to promote air circulation. Water thoroughly after planting to settle the soil around the roots.
First-Year Care and Common Issues
During its first year, a lavender plant focuses on establishing a strong root system. Newly transplanted lavender needs regular watering to help roots settle. Once established, lavender is drought-tolerant and prefers deep, infrequent watering. Allow the soil to dry out between waterings to prevent root rot. Yellowing leaves often indicate overwatering or poor drainage.
Light pruning in the first year encourages bushy growth and root development. Pinching off developing flower buds helps the plant build a robust structure. Lavender is a light feeder, and excessive fertilization can lead to leggy growth and reduced flowering. Common pests like aphids and whiteflies can occasionally affect young lavender. Insecticidal soap or neem oil can manage these pests.
