Hey, everyone! So I just made an account because it seems like a lot of people here are very knowledgeable of dawn redwoods. Anyway, I planted an "Amber Glow" one this spring and shortly after we had a mild frost. So it has had a stressful year. Overall though, it has been pulling through. But I've noticed browning leaves here and there that have these fruiting bodies on them which I'm pretty sure is some type of fungus. Has anyone encountered this with theirs and how did you treat them? There aren't many of them, so I've been removing them and spraying with copper fungicide for now. Thanks in advance for any help!

Can't say i've ever noticed that on any of mine. Only ever grew the straight species though, so mine were probably a little heartier. Where are you from?
I'm from southern Indiana. I actually transplanted it twice within a month when I got it because I am fairly new to trees and I read that when they have bound up root balls from being container grown they need to be broken up. So I dug it up to do that. Then there was a frost. Very rough first year. So I imagine it was pretty suceptible. Hopefully next year it won't have the issue if I take care of it.

twice in a season doesn't make anything happy. Hopefully it will resolve itself. I can't ever remember hearing about a DR dying, fungal or otherwise. They look like crud when they get too dry but that's about all I've seen. Super great tree to get into growing with though. I find their growth rate is rivaled only by our native elms, at least here in eastern PA
Yeah, despite the stress it still grew a foot already. I'm just disappointed there is such little information on the tree out there. None of my local arborists are familiar with it either. Although one did tell me that if it is a type of needle blight like I think it is, that once the tree is established it shouldn't be much of a problem. I hope that is the case. I'm gonna spray with copper fungicide again as a precaution in the spring though.
So I looked around for literally hours last night and I am 90% certain it is dothistroma leaf blight. I couldn't find any documented cases of it on dawn redwood, but it is a fungus that is not species specific that infects a very large range of conifers, from blue spruce to east coast redwoods. The majority of hosts are not severely impacted health-wise. They are only capable of infecting needles at a certain stage of development too. Copper fungicide is effective prevention. Since the dawn redwood is deciduous, I imagine it will be even easier to control than most other species.
I just figured I'd post this update in case it helps someone else in the future.
