Hello, all. I have what I believe is a Siberian Fir (Abies Sibirica). Someone please correct me if this is wrong. Should be possible to identify from the photos. Flat needles, green on top and two palish bands on the bottoms. Branches tend to droop, and the bark is pale grey and almost white sometimes. Overall color is kind of an olive yellowish green.
The tree was collected this past March or April. Don’t recall at the moment. Still cold. It had a good amount of field soil removed, but still has a significant amount around the roots, and was surrounded by pumice in a wooden box. The tree grew fantastically all spring and summer, but all of the sudden it’s turning brown at the growth tips, and also brown at the tips of all of the mature needles. It’s not looking good. It has been very hot here in Maryland (zone 7b) recently, and the tree has been in full sun for most of the day. I water regularly, but it’s possible I water too much. I have read (only since I noticed this issue) that Siberian Fir is very shade tolerant, and grows in moist conditions. Perhaps it’s been sunburned? That’s what it looks like to me. Can anyone advise on how I should treat it? Move to shade, I imagine. Should I prune the dead/dying tips? You’ll also see a strange yellowish area on top of the soil. I suspect a dog may have urinated on it at some point, but likely not more than once or twice. I have since moved it, and it’s been a while.
Please advise if possible. The colors in the last two pictures are more representative of the true color at the moment, since I moved it for those photos.
