Started this from a random seed found on a street about 5 years ago. Today is the first transplantation, if it survives, it’s brothers and sisters will follow! Not sure it’s optimal time for spruce transplantation, but the previous planter was 4 times smaller (soil footprint could be seen in center, with intact moss layer).
Oh, these plants are outdoor bonsai, these trees are perfectly accustomed to this climate (thick snow, -30C, some sunless days, etc) and totally do not tolerate indoor tropics.
I tried transplanting some local trees in the fall, as textbooks say, and they perished pathetically. The best time must be some other time. I suppose the best time should be early spring when roots did not wake up enough, but then I might need to break ice. Then now is fast growth slowdown moment, I suppose it must be the next best bet. I’m doing one at a time now!
