Asparagus Ag facts
An asparagus spear can grow up to 10 inches in a 24-hour period
Asparagus is a member of the Lily family
An asparagus spear grows from a crown planted 12 inches deep in the soil.
Each crown will produce spears for about 6 to 7 weeks during the season.
At the season end, the spears grow into ferns with red berries that nourish the soil with nutrients and food for a healthy crop the next season.
A healthy, well managed and cared for crop can produce asparagus for 15 years.
An asparagus planting is typically not harvested for the first 3 years.
The larger the diameter of the crop, the better the quality.
The temperature determine how long to wait between picking asparagus - In cooler temperature there may be 4 to 5 days between pickings and only 1 to 2 days during the warmer days of the season.
