Trees to not need preservatives added to their water. Check the tree at least daily for dryness. Gently grasp a branch of the tree in your hand and pull your hand toward you allowing the branch needles to slip through your grasp. Take care not to pull the tree over. If needles readily come off in your hand, the tree is too dry and must be removed immediately.
