Growing lavender is rewarding, and knowing when to transplant your seedlings is crucial for their success. Lavender thrives in well-drained soil and full sun, so it's important to consider the climate in your area. Generally, lavender seeds should be started indoors 6-8 weeks before the last frost date. Once seedlings are established and have 3-4 true leaves, it's time to harden them off. Gradually expose your plants to outdoor conditions over a week or two before transplanting them into your garden. The ideal time to transplant lavender seedlings to the garden is in the spring after the danger of frost has passed, allowing the plants to establish before the heat of summer. Ensure that you plant lavender in a location with good air circulation to prevent mold and mildew, which are detrimental to lavender health. Consider using organic mulch to help retain moisture and regulate soil temperature, but be careful not to cover the base of the plants which can lead to rot. Remember, lavender prefers a drier environment, so avoid over-watering. Incorporating these tips will help your lavender thrive and produce beautiful blooms in your garden!
