Frequently Asked Questions
Do I need to cold-stratify lavender seeds before planting?
It helps a lot. Lavender seeds have a natural dormancy, and you can break it by sprinkling the seeds on a moist paper towel, sealing it in a zip-top bag, and keeping it in the refrigerator for about four weeks before sowing. You can also let nature do the work by sowing outdoors in late fall, so the seed experiences winter before it sprouts in spring.
Will lavender survive winter where I live?
English lavender is one of the hardier types. Munstead is cold hardy in zones 5 through 9, and drainage matters as much as temperature, since lavender often struggles in cold, wet soil. Plant it in full sun, in gritty or raised soil that doesn't hold water, and cut back spent flower stems in late fall for the best chance of overwintering.
When should I harvest lavender flowers?
For fragrance and cooking, cut flower clusters or strip the flowers just as the buds begin to show color. For fresh bouquets that last, harvest in the morning when spikes are partially to fully open. Bundle the stems and hang them upside down in a dry, airy spot to dry for sachets, wreaths, or arrangements.
