The most eco-friendly choice is a live tree with roots, and we have many sizes and varieties in stock. Enjoy a live tree indoors for no more than a week so that it will stay dormant. Leave the tree in the container, dig a hole, and bury the container for the rest of winter. Water occasionally, and transplant to its permanent place in spring. (Evergreens are slow to root and grow, so we advise waiting until spring to transplant.)
In the end, Christmas isn't about the tree. It's about the people around it, so choose what makes you happy and enjoy the season!
