When should I stop harvesting my asparagus?

Question:

When should I stop harvesting my asparagus?

Answer:

Stop harvesting well established asparagus plantings in early June in southern Iowa and mid-June in northern areas of the state.  If harvested over a longer period, the asparagus plants may be weakened and less productive the following year.
