amending soil

I have a sister that just moved into an old house that has  potentially good
flower beds. The beds are full of perennials and daylilies. The problem is
that the soil needs amended a good 3-4". How can she do this short of
pulling everything out and replanting? By just putting it on top it would
bury the plants too deep. Thanks for the help.
