Douglas fir Repotting Experiment

[0soyoung]

there is another kind of fir, it sends needles only out horizontally from the branch. balsam fir was what I was referring too. anyone think this data holds true for a balsam?

Might it be Grand fir = Abies grandis?

Might it be Grand fir = Abies grandis?

Collected it in northern Michigan. its not a very impressive specimen, however, it is old, and small. I'm pretty sure its a balsam fur. collected it late summer last year for testing purposes and it appears to have survived the move south. I plan to find some better ones up there this year.

Oops! I wasn't paying attention - collected in Michigan. Abies grandis would answer your description, but it isn't a Michigan native.

Regarding the relevance or applicability of this data to other related conifers. I think it applies in general terms of growth patterns and that it can be repotted circa Aug/Sep.

I also performed the same experiment design with lodgepole pines with similar outcomes (barring a huge problem with the initial spring potting). However, climate details may also have significant effects. August/September is rainy in most of the western U.S., so humidity stress is low, but this might not be the case in some locations.
