We buy our 'real' tree at thanksgiving time,it's a tradition for us,it's when family comes to the gathering and my brother and nieces can 'assist' in the picking of it.
White pine has long needles and tends to shed them,a bit too much for a carpeted room,and the limbs are a little too weak to hold lights and ornaments.
We prefer Douglas fir,it has short needles,strong branches,good even coloration,and lasts without dropping too many needles on the floor.
A large base is suggested,one with a large enough bowl to hold about a quart of water,a tree base up to 9 inches(although you'll not get a tree with a nine inch base,it adjusts to hold any size firmly.)
Make sure the people you buy a tree from shakes the tree,mechanically,It will remove any loose debris and unwanted pests which might be in a tree while waiting for you to find it..
Have a great Christmas,
