Hi, I'm in Canada, Quebec and we have pretty cold and snowy winter here. I have these 1 year old red spruce seedlings and one tamarac seedling that I struggled to grow. They have been outdoor on a shelf all summer long and now nights beging to be cold. Is it okay to get them inside the house on my small green house until next May or June ? Thank you !
Yes, or an unheated garage. Only water about once a month - wet, cold soil is detrimental in winter.
Will the hedge survive and will it regrow green shoots?
This can be pruned, frugally, but a hard cutback is not possible. Unfortunately, you can only do light to moderate pruning.

I have a weeping, white spruce that’s about six or seven years old and about eight foot tall now. Over the years it has been slowly losing needles after they go brown and it’s going bald in areas. This was a reputable nursery where I purchased it and I took care to plant it myself in well drained soil. I mulch around the base every year and keep it watered here in South Jersey. Does this have a fungus or anything you may be aware of?
This appears to be Cytospora Canker disease. This disease is best managed rather than treated. Removal of infected material, or removing the tree, completely.
