BUT THE TREE MIGHT GROW THROUGH MY HOUSE!

Relax, the simple answer is, no. The tree wont grow through your apartment/house. A fully mature blue spruce grown in the wild can be as staggering as 75 feet tall. But one that is planted in the garden or a park usually only grows up to 50 feet tall. Plus, a tree doesn't grow that tall overnight. It takes years or even decades for a tree to be able to fully mature, so there is no risk of it destroying or damaging your property!
