Grow Lavender from Seed

If you want to grow lavender from seed it takes patience.

Like some herbal flowers, lavender can take a while to germinate and grow before you can plant it into the garden. This can be a deterrent for a home gardener, the seeds themselves can take a couple of weeks to germinate, and then growth can be slow.

How to Grow Lavender from Seed

• Choose a lavender variety and seeds from a great seed company.
• You can pre-germinate seeds or just plant them in seed starting soil.
• Set up some indoor grow lights.
• Lavender seeds are small, just barely cover with soil. If you plant too deeply they might not germinate.
• Because lavender takes a long time to grow, save space with 72 cell trays for the first few weeks
• Water until soil is moist and don’t over water. Over watering leads to many seedling problems.
• Once lavender plants are about 1 month old transplant the seedlings into larger pots.
• Lavender plants need to be at least 8 weeks old before transplanting. You can grow them much larger than that though. Many people even grow lavender in pots indoors.
• Plant after the risk of spring frost. Make sure you harden off your lavender seedlings first, they need to get used to being outdoors before shocking them.
• If there’s a lot of rain forecasted, considering covering your lavender seedlings with a portable mini greenhouse.
• Lavender can grow in low to medium quality soil but it needs to have lots of drainage.

Lavender are perennial plants that are hardy to zone 5 outdoors.

If you live in a colder growing zone, you might have to grow lavender in a container and bring indoors or in a cool basement during the winter.

How Long Does Lavender Take to Grow from Seed?

• Lavender can take a long time to germinate.
• Plants need to be at least 6-8 weeks before transplanting, but honestly, 12+ weeks is better.

Transplanting Lavender Seeds

• Transplanting lavender requires care. Once your seedlings are in the ground, it will take a couple of seasons before they’re as large as the plants you could have purchased.

My personal experience from lavender seedlings

I grew English Dwarf Munstead lavender from seed two seasons in a row. The first year I failed, the second I successfully grew and planted lavender seedlings outdoors. All summer I watched the seedlings grow surprisingly slowly. This is common with woody perennial herbs, they grow slowly the first couple of seasons then the 3rd year they are lovely and large. After spending 3 months and a summer with not much growth I bought 2 lavender plants from a local garden center just so I could witness lavender flowers. At some point I’d love to plant a lavender hedge, and I’m still undecided if I’ll spend the money on plants or just buy large lavender plants. I might do the latter, as we have elk around here and the little plants will get trampled.

I might try growing lavender from cuttings too next time!
