skgerd: Welcome to All Things Plants!
I agree with drdawg ... wait until spring for the first feeding, after the last chance of frost in your area. Shrubs will be starting their new season of growth at that time and I'm sure they will appreciate a bit of well balanced fertilizer!
If you find time to check it out, we have a specific forum here on ATP for trees and shrubs:
http://garden.org/forums/view/... where folks chat about all types of trees and shrubs that grow in their gardens.
Again,
Lin
