Gardeners desiring an old-fashioned favorite in a flowerbed should consider adding the beautiful and traditional lavender to the assortment of plants growing in a yard. When winter loses its hold and spring seems imminent, it is time to plant lavender seeds indoors in preparation for outdoor planting. By giving seeds a head start indoors, the lavender plants will have a much better chance of flowering the first season.
Fill the seed flat 3/4 full with potting soil and make the potting soil level.
Plant lavender seeds 1 inch apart in rows in the seed flat. Cover the seeds with 1/8-inch of soil. Spray the tops of the soil with the spray bottle to moisten the soil.
Place the seed flat in a location that stays approximately 70 degrees F. Spray the soil evenly with water every morning.
Watch for seedlings to emerge within approximately one month. Place the seed flat underneath a grow light when the seedlings emerge.
Fill the pots 3/4 full of potting soil and add a granular fertilizer to the soil following package recommendations for this pot size. Move the seedlings to the individual pots when the seedlings have at least two sets of true leaves by carefully scooping the fork underneath the root balls of the seedlings and transferring them to the pots. Water the transplanted seedlings generously.
Trim off the top 1/2 inch to 1 inch of the seedling to encourage it to grow out more than up.
Harden off the seedlings to the outdoors when they are at least 3 inches high and all threat of frost is over. Place the seedlings outside in a shaded and sheltered area for several hours each day for three days. Move the seedlings to a location receiving partial sun and leave them outside for a longer period. Finally, leave them outside in pots overnight.
Plant the seedlings outside in a sunny garden area with well-draining soil. Space the seedlings between 1 and 2 feet apart.
