I have a green spruce in my front yard that we got for our 2nd Christmas in this house, the 1978 season. So, 31 years later, it's thriving, and huge! Be sure you allow enough room for the tree to grow, when you select your planting spot. Our first Christmas tree here, 1977, was a Douglas Fir that we also planted in the front yard, made the mistake of not allowing enough space, and had to take it out several years later. It was sad to lose it.
It's best not to leave the tree in the house for very long, I've heard 2 weeks is about max. Be sure to keep it well away from fireplace or heaters or heater vents. Keep the root ball well watered. Enjoy!
