Asparagus harvest is in full swing - enjoy it while you can!  

 

Asparagus is a perennial vegetable crop that has a relatively short harvest season each spring.  The edible part is the immature shoot as it emerges from the crown of the plant below the soil surface and its best to harvest these “spears” early and frequently for best quality.  The taller spears pictured here are already past their prime – though they can still be eaten they may prove to be tough and fibrous. 

About the middle of June or so, it will be time to stop harvesting for the year and allow the spears to fully develop their foliage.  Quit harvesting when the majority of the spears are spindly (less than 3/8 inch in diameter). The spears will become feathery, fern-like plants that will rebuild carbohydrate reserves for the following year.
