How to Start Lavender From Seed
Lavender can be started from seed, but germination is often slow and irregular, especially with English lavender types. Starting indoors gives you better control of moisture and temperature.
Start indoors or direct sow?
Start lavender indoors and transplant after frost. Direct sowing is generally less dependable because germination is slow and seedlings need careful protection from weeds and wet soil.
When to start Lavender seeds
Start indoors 10 to 12 weeks before the average last spring frost, allowing extra time if seed packets recommend cold stratification. Transplant after the last frost, once the soil is warming and conditions are not persistently wet.
How to sow the seeds
Sow seeds very shallowly, pressing them onto sterile, well-drained seed-starting mix or covering them with about 1/16 inch of mix. Use cell trays or small pots with drainage, and follow the packet if it calls for a brief moist chilling period before sowing.
Germination
Germination often takes 14 to 28 days and can take longer. Keep soil around 65 to 70 F and barely moist, since saturated mix can cause seed and seedling losses.
Seedling care
Provide bright grow-light coverage after emergence, good airflow, and sparing water as the surface begins to dry. Thin crowded cells and remove any cover promptly after germination to help prevent damping off.
Transplanting & hardening off
Harden seedlings off for 7 to 10 days, then transplant after frost into full sun and exceptionally well-drained soil. Avoid disturbing roots, plant at the same depth, and do not mulch closely against the crown.
Tips
Check the seed packet for variety-specific chilling guidance, because requirements vary. Start extra seeds, then select the most vigorous seedlings for the garden.
