Hello,

I just purchased a new home in southern BC and we have a large hedge of cedars lining the back yard. The Cedars are maybe 12 ft tall. The yard slopes from right to left and we've noticed the cedars at the lower edge are dying. After taking a better look I've noticed the neighbour behind us has placed Irish Spring soap bars in stockings every 6 feet to deter deer from eating the hedge. Would this soap be leaching out and flowing to the lower trees and causing them to die? Any help would be appreciated. Thanks

I doubt the soap is at fault, but I don't know what is. Someone here will be along with useful suggestions.

Any suggestions besides regular watering? Certain fertilizers that work well with cedars?

Welcome! Do you know what kind of cedar these are? The ones that are all brown are not likely to revive, or are they green on the other side? I agree with porkpal it isn't likely anything to do with the soap. I would not consider fertilizer at this point, fertilizing plants with problems is not usually a good idea, the first thing is to figure out what's going wrong - since you've only just moved there it may be difficult without a history. Could any herbicide have been applied?

Question- Are you sure they are actually cedars? I tried blowing up the photos, and those don't really look like what we call cedars here in Washington just across the border from you. What we call cedars here are cousins of the true cedars, they are actually Thuja plicata (Western Redcedar). If not sure, pick some green and brown branches, hopefully with cones or something, and take them to your local nursery, they can likely help you out in ID, and maybe even on post-mortum. For example, they might know of a blight that affected lots of these, or colder than usual weather, or flooding in the area.
I think you might ask the neighbors if they know anything about it, they might know what happened (lots of Roundup, for example, or brush killer on Blackberries before the sale, to tidy up the place).
