* Asparagus is a perennial and does not produce vegetables in the first year. Start seeds indoors 12-14 weeks before the average last frost date. Plant seedlings outside when soil can be worked in spring, usually 2-4 weeks before the average last frost date. Most people plant crowns or seedlings instead of growing from seed.
