Lavender (Lavandula) is a highly aromatic perennial herb that is native to regions in the Mediterranean. It has a broad range of uses which makes lavender a highly coveted herb. It can be used in cooking when creating jams or stews, in aromatherapy, and other household and cosmetic uses. Lavender can grow to reach between 12 and 24 inches in height and is hardy in the USDA zones 5 to 9. Planting lavender from seed is best accomplished about six to eight weeks before the last spring frost date in your growing region.
Preparing Lavender Seeds
Place the lavender seeds inside of a zipper top plastic bag.
Measure out approximately 2/3 to 1 cup of seed-starting potting mix. Pour water into the mix until the mix is well moistened.
Place the mix inside the plastic bag. Place the bag in a refrigerator for three weeks. The temperature should be set to remain between 35 and 40 degrees F. Check on the bag every three to four days to keep the mix moist; spritz with water as needed.
Remove the bag from the refrigerator after the three weeks has passed and plant the lavender seeds.
Planting Lavender Seeds
Scoop in a good quality sterilized seed-starting mix into 3- or 4-inch wide peat pots, or planting packs, until each pot or cell is full.
Press the mix down firmly in the peat pots or planting packs using your fingers or the back of a spoon.
Place the planting packs or peat pots into a watering tray or similar container that can hold about 1 inch of water.
Plant three lavender seeds per peat pot. If you are using planting packs, plant two seeds in each cell. Space each seed approximately 1/2-inch apart. Gently push the seeds into the mix to ensure good soil-to-seed contact.
Sprinkle no more than 1/8 inch of seed-raising mix over each of the lavender seeds. Mist the surface of the soil in the peat pots until the mix is visibly moistened. If using planting packs, pour water into the watering tray and let the packs absorb the water until the mix is moistened.
Transfer the tray into a warm and brightly lit location in your home that won't subject the tray to any direct sunlight. A good location is near a south- or west-facing window. The temperature should be kept at approximately 70 degrees F.
Pour water into the tray when needed to keep the mix in the packs moist. Avoid letting the mix become soggy which can cause the lavender seeds to rot. If using peat pots, mist the surface of the soil when needed. Expect the lavender seeds to begin germinating in two to three weeks.
Thin out the seedlings in each of the planting receptacles so there is one lavender seedling per cell or peat pot. To do this, chose which seedling appears to be the hardiest. Cut the other seedlings off at the soil line. The soil should be kept just barely moist, never sodden.
Transplant the lavender seedlings when each is about 3 inches tall.
