Fresh-market asparagus prices demonstrate a very pronounced
seasonal pattern. They are highest at the beginning of the
season (January-March) and at the end of the season (August-
September) when shipment volume is smallest. During the high-
price periods, southern California (the Imperial Valley) is the
principal shipper. Fresh-market prices are generally lowest in
mid-season (April-May) when shipment volume is greatest and
harvest is peaking in central California, Washington, Michigan,
and other states.
