“Harvest is typically a six to seven week season. Harvest is typically in full swing around the middle of May and through June.  Michigan moved up in the ranks as the 2^nd largest producer of asparagus in the nation, producing just less than 21 million pounds.  It’s nutritious, flavorful and one of Michigan’s first signs of spring. Michigan asparagus is the state’s first green vegetable harvested each year. A typical Michigan asparagus harvest begins in mid-April, but in wake of a long, cold winter and cooler spring, it can be pushed back.”
