Seed Treatment
Soaking: Soak seeds in lukewarm water for 12 hours to soften the seed coat and improve germination.
Cold Stratification: After soaking, place seeds on a moist paper towel inside a plastic bag and refrigerate for 6 weeks (42 days).
Note: If seedlings begin to sprout in the fridge, remove and plant them immediately.
Germination Time
Optimal: 14–21 days
Sub-optimal: Up to 40 days
Temperature
Seeds germinate best at 18–21°C (65–70°F). Use a heat mat if necessary.
Light Requirements
Lavender seeds need light to germinate. Sow on the surface and press gently—do not cover with soil.
Planting Depth & Spacing
Surface sow only. After germination, transplant with 30 cm (12") spacing between plants.
Post-Germination Care
– Keep in a bright, well-ventilated area.
– Water lightly and let the surface dry between waterings.
– Transplant outdoors after frost risk is over and seedlings are 5–8 cm (2–3") tall.
Growing Tips
– Use well-draining, sandy soil in full sun.
– Avoid overwatering—lavender prefers drier conditions.
– Trim lightly after flowering to maintain shape and promote bushiness.
Bloom Time
Flowers appear in late spring to early summer, usually in the second year.
Lifespan
Perennial in zones 5–9—returns year after year with care.
