I've grown several of these from seed. The seedlings are in the second year, and there has been some attrition, but I think I still have about 30 healthy young plants.
I have a Blue Spruce but I don't think it's a Colorado Blue. All the lower branches and dead so I cut them off. Is there anything I can do for this tree? TIA
Here is a response from Ken: "There are many horticultural varieties of blue spruce, some have needles that are a deeper blue shade than others.
The problem with your tree (dying lower branches) is likely caused Spruce aphids, which can cause severe damage to blue spruce trees. If untreated, the aphids will progressively kill the branches on your tree, possibly leading to mortality. Most of the damage is done during the winter. If you shake the branches of your tree over a piece of newspaper and observe many aphids have fallen from the branch, you could consider having the tree sprayed by a professional arborist to apply an environmentally friendly horticultural oil that will kill the aphids. (The treatment may need to be repeated periodically in years when the aphid population is high).
Cutting off the dead branches doesn’t affect the aphids, but it does help the aesthetic appearance of the tree.

they are adapted to dry cold climates but they are also often planted in warmer and wetter places due to their iconic bluish colour
Educational. Thank you.

안녕하세요. 한국에서는 은청가문비라고 해요. 가문비 나무의 색감의 매력에 빠져서 이베이로 씨앗을 구매를 했습니다. 나무에 관해서 모르지만 나무가 주는 행복감을 점차 많이 느끼고 있습니다. 선생님의 유튜브 영상이 저에게 많은 도움이 되였습니다 감사합니다.

Good luck with your spruce tree!"
@@SimplyScienceNRCan Thank you so much Ken. I will check for aphids and if I don't find any, I guess it's the fungus?
It's hard to hear the host over the shitty music.
