  Feeding perennials in containers really depends on the individual plant's requirements.  It will differ according to the time of year as well as the type and depth of compost used and how often it is replaced or refreshed.  Some perennials prefer rich, water retentive growing conditions, some prefer impoverished, free draining soil and others will prefer a regime between these two extremes.  Some perennials would prefer not to be in containers at all!
  
  You can check up on a plant's preferred growing conditions by looking at the details on a reputable supplier's website or by referring to the RHS plant database:

  What plants are you growing?
  
  As a general rule I would always err towards under-feeding. If you are providing a top dressing of manure in the spring... in truth that's probably going to be enough for many perennials. Some perennials won't appreciate a mulch of manure, but these tend to be more tolerant of low fertility anyway.
  
  If add additional feed during the summer I would be sparing; better to under-do it than over-do it. So, maybe half the recommended dilution.
  
  Plants that like humus rich soil - if you are potting them in suitable humus rich soil they should be happy.  
  
  BTW every few years it would be a good idea to lift your perennials and split/repot them, with some fresh compost, to avoid the pots becoming root bound.
