What To Know
- Water the seeds gently using a spray bottle or a watering can with a fine nozzle.
- Dig a hole twice the width of the root ball and plant the seedlings at the same depth they were in the seed tray.
- Cut the flower stems just below the flower heads and dry them in a cool, dark place.
Lavender, with its fragrant blooms and calming properties, has captivated gardeners for centuries. While purchasing lavender plants is an option, propagating them from seed offers a rewarding and cost-effective alternative. This comprehensive guide will walk you through the steps of how to propagate lavender from seed, ensuring success in your lavender-growing endeavors.
Selecting Seeds
The first step in propagating lavender from seed is selecting high-quality seeds. Look for reputable seed suppliers and choose varieties that are suitable for your climate and growing conditions. Some popular lavender varieties include:
- English Lavender (Lavandula angustifolia): Hardy and thrives in well-drained soil.
- French Lavender (Lavandula dentata): More compact with broader leaves and pink-purple flowers.
- Spike Lavender (Lavandula latifolia): Larger with taller flower spikes and a stronger fragrance.
Preparing the Growing Medium
Lavender prefers well-draining soil with a pH of 6.5 to 7.0. To create an optimal growing medium, mix 1 part potting soil with 1 part perlite or coarse sand. Ensure the pots or seed trays have drainage holes to prevent waterlogging.
Sowing Seeds
Sow the lavender seeds thinly on the surface of the prepared growing medium. Gently press them into the soil but do not cover them. Lavender seeds need light to germinate.
Providing Light and Temperature
Place the pots or seed trays in a warm, sunny location. Lavender seeds germinate best at temperatures between 65°F and 75°F (18°C to 24°C). If necessary, use a grow light to supplement natural sunlight.
Watering
Keep the growing medium moist but not soggy. Water the seeds gently using a spray bottle or a watering can with a fine nozzle. Avoid overwatering, as this can lead to damping off, a fungal disease that can kill seedlings.
Germination
Germination typically takes 10 to 21 days. Once the seedlings emerge, provide them with plenty of sunlight and continue to water them regularly.
Transplanting
When the seedlings have developed their first set of true leaves, they are ready to be transplanted into individual pots or into the garden. Dig a hole twice the width of the root ball and plant the seedlings at the same depth they were in the seed tray. Water them well after transplanting.
Growing and Care
Lavender plants require well-drained soil, full sun, and occasional watering. Deadhead spent flowers to encourage new growth and prevent seed formation. Fertilize the plants lightly in the spring with a balanced fertilizer.
Harvesting
Lavender flowers can be harvested when they are in full bloom. Cut the flower stems just below the flower heads and dry them in a cool, dark place. Dried lavender can be used for sachets, potpourri, or culinary purposes.
Troubleshooting
Problem: Seedlings are leggy and weak.
Solution: Provide more sunlight or artificial light.
Problem: Seedlings are damping off.
Solution: Reduce watering and improve drainage.
Problem: Lavender plants are not flowering.
Solution: Ensure the plants are receiving enough sunlight and are not overwatered.
