Make a fresh cut on the base of the trunk to remove its natural seal that forms if it’s not placed in water shortly after being cut. The amount to cut off can vary depending on how soon you can place the cut tree into fresh water. The fresh-cut surface should appear creamy-white, not yellow or brown.
Place the tree in a stand which will hold at least one gallon of water or check the water level more than once a day. An average tree may consume between two pints and a gallon of water per day. If the water level drops below the butt, a new seal will form which prevents the tree from taking up more water. Water consumption is related to butt diameter and not to height.
If the tree is not going into the house soon after purchase, it should be stored on a cool porch or patio away from wind and sun.
Use the smallest lights possible to prevent any build-up of heat.
Place the tree away from heat sources such as vents, fireplaces, radiators or sunny windows.
Do not store Christmas trees in swimming pools to avoid the potential of chlorine-bleaching.
