How to Germinate Lavender Seeds

By Robin Coe ; Updated September 21, 2017

Lavender seeds are much easier to care for than they are to germinate from seed. The plants are typically grown from cuttings; however, with the proper care you can start your plants from seed. Once you germinate your lavender and begin growing them in your garden, there are many things you can do with the flowers you harvest. Lavender is common in aromatherapy, can be used for cooking and is great in potpourri mixes to freshen your home.

Add 1 tablespoon of potting soil to each of your plastic bags. Mix in enough water to barely moisten the soil. Add 2 lavender seeds to each bag, seal, and place in the refrigerator for 6 weeks. Do this about 16 weeks before the last frost. Bring your seeds to room temperature when you are ready to plant them.

Begin planting your seeds about 10 weeks before the last frost by filling your starter tray with potting soil. Press the contents of each bag ΒΌ inch deep into the soil of separate sections of the tray.

Water your lavender seeds immediately, and make sure your starter tray has good drainage. Cover your starter tray with the lid to increase humidity and promote germination.

Place a grow light about 6 inches from your starter tray. Keep your grow light on for about 16 hours a day.

Water your lavender seeds with just enough water to dampen the soil with out making the soil soggy. Your lavender seeds should germinate within 50 to 60 days. However, it can sometimes take longer.

Select an area in your yard that gets plenty of drainage and full sun. The best location for lavender to grow is in an area facing South. Loosen the soil by digging about 8 inches into the ground. Break up an clods with your shovel, and remove all the weeds.

Use a pH tester to test the pH of your soil. It should be between 6.5 and 7.5. Add compost to the soil if the pH level needs to be balanced.

Thin your lavender plants when they are a couple inches tall so that there is only one seedling in each section of your starter tray. Dig a hole big enough for each plant's root ball in your garden area. Space the holes about 3 feet apart.

Transplant your lavender after the last frost by putting the root ball into the soil and pressing the dirt around the crown of your plants. Add mulch around your lavender plants, but keep the mulch at least 3 inches from the stem. Water immediately. Repeat watering twice a week.
