Debi,

In general, only commercial growers who want to maximize increase dig
every year.

Most of us prefer the effect of two- or three-year clumps, 
and sometimes situations make us go to four.

Dig when overcrowding gets to be a problem (reduced bloom 
is one symptom), or to make room for something new.

Otherwise, no need to.

That said, there are a few cultivars that are such 
vigorous growers that every year works best for them 
(and which cultivars are like this varies from 
region to region, garden to garden).
