What is happening to my cedar?

Postby Foghorn Leghorn » Jul 31, 2014 4:35 pm

Hi all,

A couple of weeks ago, my wife and I noticed that the top half of one of our cedars out front was drying up. I've tried giving it a fair bit of water but it doesn't seem to have helped at all, and now it appears even worse. The other two cedars we have are fine (one is in one of the below photos), but this one might have received more damage from the December ice storm in Toronto than the others. But if that was the case, why would it have taken so long to show symptoms? Shouldn't the symptoms have already shown in the spring? I've included links to a couple of photographs to illustrate what I'm trying to explain:

Or is this something else that someone might recognize?

You are right, this damage should have been evident earlier.....looks like your cedar is dying back....
One cause may be from a flatheaded cedar borer......the only way to tell, is to inspect the trunk at the area where browning starts.....
In any event, the cedar will not recover and should be removed.....

Thanks for the reply, Ian. Do you think it's worth cutting the top half off at the dead point, and hoping for it to eventually grow back again? Or do you think the whole thing should be removed at this point?

Cedars will not regenerate new growth from old growth (unlike Yews that will)....so it will never regain its previous shape, so I would remove it and replace it with another plant......
I would recommend you research buying a conical Yew instead of a cedar.....since they will grow new growth from old wood, you can keep the plant the size you want by pruning it....whereas a cedar, you can only trim the outher active growth and over time the cedar will become larger

Thanks very much for the tips, Ian. I will look into conical Yews as a replacement!
