|We planted two Monrovia Dwarf Alberta Spruces early this past fall. Over the past few months of winter, I've noticed that the needles are turning brown. Specifically, the needles toward the tops of the trees and facing SOUTH are the brownest, the rest have a brown tint to them. I checked the inside toward the trunk and they definitely seem much greener (with the exception of a couple spots of bright brown- almost orangish in color). The branches themselves seem nice and flexible, but needles are falling off of them. Is it normal for them to 'shed' a bit, or no? These are planted at the front of the house, on either side of the front door. The house faces EAST. They really don't get much protection from any of the elements. (I'm not sure if that makes a difference to you with wind, sun, etc.) I have to admit, I'm not super concerned since there is a one year warranty on them, but I do want to find out what may be happening with these, as we'd like to replace them with the same thing, if need be.
