Asparagus has been in cultivation more than 2,500 years, and in the United States since the 1870's. It was also prized as an aphrodisiac. A. Asparagus is planted in the ground three years before it can be harvested for the full season.
Farmers only harvest for a short period of time the first few years to allow for further growth.
The mature plant is harvested all season which typically stretches up to 90 days. A. Asparagus will grow 7 inches in a day when temperatures reach 90 degrees. Some say you can lie on the ground and watch asparagus grow. The asparagus beds are cut every day, and the length of harvest is generally 70 to 80 days. This is a matter of personal preference.
