Choosing the Right Lavender Seeds

When growing lavender from seed, it’s important to consider all the variables to choose a variety. Consider your daily sunlight hours, your maximum and minimum yearly temperatures (hardiness zone), and your soil conditions.

Selecting Your Variety: There are several varieties of lavender. For beginners, Lavandula angustifolia (English lavender), known for its sweet fragrance, is a great choice. This variety is tolerant of most climates and soil conditions, being hardy down to zone 5. Along with other lavender varieties, English lavender is very drought tolerant and can survive hot summers.
Buying from Reputable Sources: To ensure quality and germination rates, check out SeedsNow. SeedsNow is an online seed company that focuses on quality over anything else. They carry only organic, non-GMO seeds that are tested for quality and guaranteed to grow in your garden.

Choose a lavender variety that will grow well in your climate and that can tolerate your growing conditions. But above all, choose a variety that you like!

Preparation Is Key: Start Indoors

Lavender is a long-season crop and can be relatively slow to grow, especially from seed. That being said, it’s important to start your seeds indoors to give them a head start on the growing season.

Timing: Start your seeds indoors about 8-10 weeks before the last frost date. This gives them the right amount of time to get established before the harsh outdoor conditions.
Soil Prep: Use a well-draining, light soil mix to aid germination. It’s important to use a well-draining soil mix, such as this seed starting mix from Espoma Organic, as it prevents the seeds from rotting in the soil.
A Personal Touch: I had more success when I added a thin layer of sand to the top of the soil, mimicking lavender’s natural gritty habitat. Lavender is native to the Mediterranean region, meaning they prefer very loose, sandy, and less-than-ideal soil.

Sowing Your Seeds for Optimal Growth

The Right Depth: Lavender seeds should be sown on the surface, as they need light to germinate. Gently scatter a few on the surface of your filled seedling cells.
Cold Stratification: Lavender seeds require a cold period in order to germinate, mimicking their natural cycle. This can be achieved by placing the seedling cells (soil, seeds, and all) into the fridge for 2-3 weeks. After this period, move the cells to a warm area to continue growth.
Keep Them Moist: Use a spray bottle to keep the soil moist but not soggy, avoiding burying the seeds beneath the soil.
Patience Pays Off: It can take 2-4 weeks for lavender seeds to germinate. Keeping them in a warm, bright spot after stratification accelerates growth. Please be patient!

The Transition: Moving Lavender Outdoors

As your lavender seedlings get ready to move into their forever home outdoors, it’s important to make the transition smooth. The conditions indoors are nothing in comparison to the conditions outside in your garden.

Acclimatization: Gradually introduce your lavender plants to outdoor conditions to prevent shock. Do this over a period of 1 week, increasing the number of hours outside by 2 each day. (Ex: first day seedlings out for 2 h, second day seedlings out for 4 h, third day 6, and so on until you reach 1 week). Linda from Garden Betty.com shares her tips for hardening off seedlings here.
Location, Location, Location: Choose a spot with full sun and good drainage. Lavender thrives in dry, sandy environments. I would say that the more sun you give lavender, the better they grow. If you can get away with 10-12 hours of sunlight per day, do it!
Containers: Lavender plants thrive in containers because of their excellent drainage. Containers and grow bags dry out quicker than raised beds, allowing your lavender to grow beautifully. Additionally, you can move the containers with the sun every day to allow for better exposure.
Spacing for Success: Plant seedlings about 18 inches apart to allow for air circulation and growth. This will give them enough space to grow to their full size.

Ongoing Care for Thriving Lavender

Watering Wisdom: Lavender does not like wet feet. Water only when the soil is dry to the touch. To learn more, check out our post on watering tips and techniques.
The Fertilizing Debate: Generally, lavender requires little to no fertilizer. If your soil is very poor, opt for a small amount of slow-release, phosphorus-rich organic fertilizer. I also add a thin layer of compost every spring to my lavender to facilitate healthy growth.
Pruning Practices: Pruning early and annually encourages robust growth. Trim back in spring to shape the plant and promote new growth.
