I live in zone 5b. There are two decorative evergreen trees/shrubs, one on
each side of the porch facing south. I never have fertilized since moving
into this house. They just aren't looking that good, some of the needles
are browning and I didn't see much new growth last spring.

They are shaped like christmas trees and are about ten feet tall. They do
not have sharp needles, more like light green finger type foliage. I wish I
knew what it was but I don't.

What do you suggest I do this spring to get them back in shape?
