How to cultivate lavender from seed It may be more cost-effective to grow lavender from seed in order to create a long, low hedge. Most people prefer to purchase lavender plants that are already grown, but if you’re on a budget or enjoy a challenge, you can grow lavender plants from seed.
- From February to July, sow lavender seeds on the surface of moist seed compost.
- Cover the seeds with vermiculite or compost that has been finely sieved.
- Place the seed tray in a propagator at 21 to 25 degrees Celsius (70 to 75 degrees Fahrenheit) or seal it in a clear polythene bag until germination, which can take up to 21 days.
Keep the compost moist, but not drenched, and do not block out light, as both of these factors promote germination. When the seedlings are large enough to handle, transplant them into 7.5cm (3″) pots and grow lavender plants on in cooler conditions until they are well established. 
How long does it take for English lavender seeds to germinate?
Learn About Growing Lavender – To ensure that your lavender seeds germinate well, sow the seeds early and place the seed tray on a heat mat or in a warm location. Instead of traditional potting soil, use a very light mixture or fine vermiculite that drains rapidly.
In approximately two weeks, the seedlings will germinate and take a while to resemble lavender. Ensure that the lavender seedlings receive adequate water, but do not allow them to become soggy, and place them in direct sunlight for optimal health. When your little lavenders have several sets of leaves, place them in their final location, but be sure to check on them frequently to ensure that they have not been knocked over by animals or washed away by rain.
Once the lavenders are established in the soil, they will grow slowly the first year, but the majority of them will bloom, and by the following year you will have a magnificent supply of lavender to use as a hedge or as a colorful border for your perennial bed.
Can I just scatter lavender seeds?
Temperatures between 55 and 72 degrees Fahrenheit produce the best results. Outdoors, scatter the seeds on the soil and then lightly cover them with a row protector or soil. Additionally, lavender can be grown from cuttings.
