Is there some web page that gives detailed information about which of
perennials and shrubs need to be cut back in fall and how to do it?


I'm not aware of any shrubs that need to be cut back. Sometimes people
prune shrubs to promote flowering, but it isn't a necessity. Of course
pruning some shrubs like azaleas in the fall will remove all the flower
buds. Pruning shrubs late in the fall can often stimulate grow that doesn't
have time to harden-off before winter hits. I

Not all but many shrubs decline in a very few years if never pruned, while
others stop producing flowers hence fruit & seeds therefore stop
reproducing if never pruned. Round here, in nature, it would be deer,
elk, bears, insects, & even the wind that do the pruning. In our gardens
we have to take over that natural chore. And Jenny's original question
about finding a central list of detailed information about which & when is
a good question, though I'm not sure a central source of information
exists & the care of each shrub or perennial in one's garden may well have
to be researched one at a time until the gardener slowly gains a general
knowledge of the care of sundry plant groups.
