Asparagus was depicted in Egypt nearly 3000 years ago. It was a common vegetable early in European history.It is a perennial crop that can live as long as 20 years once it becomes established. Plant your seeds inside and put plants out after the last frost in your area. Start the seeds about 14 weeks before the last frost and allow up to 3 weeks for the germination process. Harvest begins in year 3. Mulch them well in the fall, and allow them to grow without harvesting during the first 2 growing seasons. They can be grown in zones 2 – 11, but they prefer temperate climates. Space 2 – 3 feet apart.
