Answer
Dear Kelly:

Asparagus usually has a life of approximately 15 years.  Thinning asparagus in the first or second year after planting is appropriate.  However, thinning at mid-life stage is not advised.  Transplanting the existing plants should be done in late summer or early fall.  Listed below are  websites that should provide you with useful reference information about this delightful delicacy:
