Thanks everyone for your support about my case for taking down just one more tree in our yard! Update: I managed to convince my husband that we SHOULD take it down... someday, but not now. He insists for safety reasons that we should have it done professionally. How annoyingly practical and responsible of him! Anyway, I think if I prepare myself over the next year (and save up some gardening budget) I might be able to stomache spending over $600 next year to take it down, then deal with the wood and stump myself. I KNOW I would love the results and the garden would be happier for it!
I was hoping someone out there would say they would take it down for me in exchange for $600 worth of garden coaching... but no such luck!
I also agree with Ms. S's comment about scale, but with 4 other towering spruce in the front yard, my house will still look out of scale! They do insulate the house from wind a lot more than smaller trees would though, so they're not all bad.
As for Paula's warning about my kids coming home with more spruce trees when they're each in Grade 1, I think if I trade them for a perennial that flowers in their favourite colour I will be safe!
