How to keep a cut Christmas tree fresh (and safe)

Quick answer

Short version: make a fresh cut of about half an inch off the base if the tree has been out of water for more than a few hours, put it in water right away, use a stand that holds about a quart of water per inch of trunk width, never let the water drop below the base, and keep the tree at least three feet from heat sources.

1. Make a fresh cut

When a tree is cut, sap seals the base over time and makes it harder for the tree to take up water. The National Christmas Tree Association recommends removing about a half inch disk from the base before putting the tree in its stand, if it has been out of water for a while. Cut straight across, not at an angle or into a V. You do not need to drill holes in the trunk.

If you cut the tree yourself at a farm and drive straight home, it may still be fine. When in doubt, recut.

2. Use a stand that holds enough water

A common rule of thumb from the NCTA is a stand that holds about one quart of water for every inch of trunk diameter. A tree with a 4 inch trunk wants a stand that holds about a gallon. Many small decorative stands hold much less. Do not shave the bark off the sides of the trunk to make it fit; the outer layers are what take up water.

3. Check the water every day

A fresh tree can drink a lot in the first few days. Check morning and evening at first.
Never let the water drop below the base of the trunk. If it does, the base can seal again.
Plain tap water is fine. The NCTA says additives such as sugar, aspirin or commercial mixes are not needed.
A watering can with a long spout, or a funnel and tube, makes topping up easier without moving presents.

4. Pick the right spot

The National Fire Protection Association advises keeping the tree at least three feet from any heat source, such as fireplaces, radiators, space heaters, heat vents, candles and lights. Heat dries a tree out faster, and a dry tree is a fire risk. Make sure the tree does not block an exit.

5. Lights and safety

Use lights made for indoor use and listed by a recognized testing lab. Throw out sets with worn or broken cords or loose bulb connections.
Follow the maker's limit on how many light strands to connect.
Turn off tree lights when you go to bed or leave home.
Keep a working smoke alarm near the room.

6. Know when it is time

A well watered fir or pine can look good for several weeks, but every tree eventually dries out. Signs it is time to take it down: lots of needles falling when you brush past, needles that snap instead of bend, and a tree that stops drinking. NFPA advises getting rid of the tree after the holidays or as soon as it is dry, and not leaving it in the house or garage.

7. Recycle it

Many cities and counties collect trees after the holidays for mulch or compost, usually with ornaments, lights, tinsel and stands removed. Some ask you to bag the tree to get it out of the house without dropping needles; a tree disposal bag helps there. Check your local public works or waste site for dates and rules.

Quick answers

How long will a real tree last? It depends on the species, how fresh it was and how well you water it. Many people keep a well watered tree up for about four to five weeks; take it down sooner if it gets dry.
Does a warm room matter? Yes. Lower room temperatures slow drying, so keep it away from heat and sunny windows where you can.
My tree is not drinking. Why? The base may have sealed. Take it out, recut the base and put it straight back in water.
