How to Keep a Christmas Tree Fresh (and Not on Fire)

A real Christmas tree is pure magic. The smell, the slightly lopsided branches, the family argument about which side faces the room. It's also a cut plant that started dying the day it left the farm, and your job is to slow that down until New Year's.

The good news: keeping a tree fresh comes down to three things. A fresh cut, a stand that never runs dry, and a spot away from heat. Get those right and your tree stays green, holds its needles and stays safe. Here's the whole game plan, from the tree lot to the curb.

Measure Before You Buy

Measure your ceiling before you leave the house. Then subtract the height of your stand and your tree topper. That's the tallest tree you can buy. A tree that's a foot shorter than the ceiling looks just right.

Measure the width of the spot, too, and your front door if you're dreaming big. Trees look smaller outdoors. Every year, somebody brings home a 9-foot tree for an 8-foot ceiling and ends up sawing off the top in the driveway.

How to Pick a Fresh Tree

•      Bend a needle. A fresh fir needle bends. A dry one snaps.

•      Run your hand along a branch. A few needles should come off, not a handful.

•      Lift the tree and drop the trunk on the ground. Some brown needles falling from the inside are normal, since trees shed old needles. A shower of green needles means it's dry.

•      Check the color. You want deep green, not dull or gray-green.

•      Ask when it was cut. A lot that gets weekly deliveries beats one that got its whole season's trees the day after Thanksgiving. Cut-your-own farms win, hands down.

•      the day after Thanksgiving. Cut-your-own farms win, hands down.

Which kind lasts longest? Fraser fir and noble fir hold their needles best. Douglas fir and balsam fir smell wonderful and last well with steady water. Spruce drops needles fast indoors.

Pick a fresh tree with a flat side over a perfect tree that's already dry. The flat side goes against the wall. Walls are famously nonjudgmental.

Getting It Home

Have the lot wrap the tree in netting. Tie it to a roof rack (or the roof, over an old blanket) with the trunk toward the front of the car, using real rope or ratchet straps, not the lot's flimsy twine.

Run the rope through the car doors only if they'll still close all the way. Drive like you've got a tree on the roof, because you do.

Make a Fresh Cut

When a tree is cut, sap seals the end of the trunk within a few hours, and a sealed trunk can't drink. So before the tree goes in the stand:

•      Saw 1 to 2 inches off the bottom of the trunk, straight across.

•      Don't cut it at an angle, in a V or into a point, and don't drill holes in it. A flat cut drinks best and sits steady in the stand.

•      Get it into water right away, within a couple of hours.

If the lot made the fresh cut and you get the tree into water the same day, you're set. If it's been sitting in the garage overnight, cut again.

Get a Stand That Holds Enough Water

This is the most important purchase of the season. A stand needs to hold at least 1 quart of water for every inch of trunk diameter. A 4-inch trunk needs a stand that holds at least a gallon. Bigger is better.

The stand should also grip the trunk without whittling it down, hold the tree straight, and be easy to refill. The KRINNER Tree Genielocks the trunk in place with a foot pedal and holds a big reservoir of water. No more lying under the tree turning screws while somebody yells "left, LEFT."

Water: The Whole Secret

A fresh tree drinks about a quart of water per inch of trunk diameter every day, and it's thirstiest the first week. A tree with a 4-inch trunk can go through a gallon a day.

•      Check the water twice a day for the first week, then every day after that.

•      Never let the water drop below the bottom of the trunk. If it runs dry even for a few hours, the trunk can seal over again, and then it stops drinking no matter how much you add later.

•      Use a long watering funnel so you're not crawling under the branches with a pitcher. A Christmas tree watering funnel runs a tube down to the stand and makes daily watering a 30-second job.

•      Use plain tap water. That's it.

What not to put in the water: sugar, corn syrup, aspirin, soda, bleach, commercial "tree food" or vodka. Tree growers and university researchers agree: plain water works best, and some additives make the tree dry out faster. Your Christmas tree does not need a cocktail. It needs a drink.

Where to Put It

•      At least 3 feet from heat. That means the fireplace, radiators, heat vents, space heaters and candles. That's the National Fire Protection Association's rule.

•      Out of direct sun. A sunny window dries out a tree fast.

•      Clear of doorways, hallways and stairs. The tree should never block a way out of the house.

•      Somewhere cool. Turn the thermostat down a couple of degrees. The tree lasts longer and so does your heating budget.

Set It Up Safely

•      Let it settle. Cut the netting and give the branches a few hours, or overnight, to drop into place before you decorate. Then turn the best side toward the room.

•      Test the stability. Give it a gentle push. If it wobbles, fix it now, not when it's covered in Grandma's glass ornaments.

•      Anchor it if you have cats, toddlers or a big tail-wagging dog. Screw a small hook into the wall or window frame and tie the trunk to it with clear fishing line. Nobody will see it, and the tree stays upright.

•      Leave a way in under the tree skirt. A skirt that covers the stand is fine, as long as you can still reach the water every day. Tuck it loosely or use one with a back opening.

Light It Safely

According to the NFPA, 41% of home Christmas tree fires involve electrical or lighting equipment. These are the easy fixes:

•      Check every strand before it goes on the tree. Toss any with frayed wires, cracked sockets or loose bulbs.

•      Buy lights with a UL, ETL or CSA label from a recognized testing lab, and use indoor lights indoors.

•      Go LED. LEDs run much cooler than old incandescent lights and use a fraction of the electricity.

•      Follow the package limit on how many strands to connect end to end. It's on the box. Read it.

•      Turn the lights off when you go to bed or leave the house. A timer or smart plug does it for you.

•      Never put real candles on or near the tree. Not even for a minute, not even for the photo. Use flameless candles.

Kids and Pets

•      Cover the stand. Tree water collects sap, bacteria and whatever was sprayed on the tree at the farm. Don't let the dog or cat drink it. A tree skirt or stand cover keeps noses out.

•      Put breakable, small, sharp and sentimental ornaments up high. Unbreakable ornaments and soft ones go on the bottom branches where small hands and wagging tails can reach.

•      Skip tinsel if you have a cat. Swallowed tinsel can cause an intestinal blockage, which means emergency surgery.

•      Tuck cords out of reach and away from chewers.

Your Daily 60-Second Tree Check

Every morning, with your coffee:

1.     Check the water. Fill it to the top.

2.     Bend a needle or two. Still bending? Good.

3.     Look at the floor. A few needles are normal. A carpet of them isn't.

4.     Give the tree a gentle nudge to check it's still stable.

5.     Make sure the lights are off if nobody's in the room.

Going away for the holidays? Turn the lights off and unplug them. Fill the stand to the top. If you'll be gone more than a day or two, ask a neighbor to water it. The tree doesn't know you'll be back Sunday. If it's already dry, take it down before you leave.

Can You Revive a Dry Christmas Tree?

If the stand ran dry for a few hours and the needles still bend, refill it right away and watch to see if the water level drops. If the tree is drinking again, you're fine. If it's not drinking, take it out of the stand, saw another inch off the trunk, and put it back in water.

If the needles snap, the branches are brittle, or needles fall when you brush past it, the tree is done. A dry tree burns fast and hot. Take it down.

When to Take the Tree Down

A well-watered fresh tree usually stays fresh for about four weeks. Take it down when:

•      The needles snap instead of bend,

•      It's dropping needles every time someone walks by, or

•      It's stopped drinking water.

Whichever comes first. Christmas Day is not a deadline you have to wait for. Neither is New Year's. A dry tree goes, even if it's December 20. And February does not need your Christmas tree.

According to the NFPA, a third of home Christmas tree fires happen in January, so don't let it linger. Don't store the tree in the garage or prop it against the house, either. Take it to the curb or recycling center.

How to Get the Tree Out Without Covering the House in Needles

1.     Take off every ornament, light, hook and strand of tinsel.

2.     Drain the stand with a turkey baster or a wet/dry vacuum, so you're not sloshing water across the floor.

3.     Slip a big plastic tree bag (or a mattress bag) over the tree from the top down, then tip it over.

4.     Carry it out trunk first. The branches fold back instead of catching on the door frame.

5.     Get the vacuum. You'll be finding needles in July anyway.

What to Do With the Tree After Christmas

Most cities and towns pick up trees curbside for a few weeks after the holidays, or have a drop-off spot where they're chipped into mulch. Check your city's website for dates. Take off everything first, including the stand, the lights and every bit of tinsel. Tinsel ruins the mulch.

Other good uses: cut the branches to cover tender plants in the garden through the winter, or prop the tree up outside as a bird shelter.

Never burn your Christmas tree in the fireplace. Dry evergreens burn too fast and too hot, throw sparks, and leave creosote in the chimney.

Frequently Asked Questions

How often should you water a Christmas tree?

Every day, and twice a day the first week. A fresh tree drinks about a quart of water for every inch of trunk diameter each day. Never let the water drop below the bottom of the trunk.

Should you put anything in Christmas tree water?

No. Plain tap water works best. Sugar, aspirin, soda, bleach and commercial additives don't help, and some make the tree dry out faster.

Do you have to cut the bottom of a Christmas tree?

Yes, unless the lot made the cut and you got it into water the same day. Saw 1 to 2 inches off, straight across, right before it goes in the stand.

How long does a real Christmas tree last?

About four weeks with a fresh cut and steady water. Fraser and noble firs often last longer. A tree that dries out goes sooner, whatever the date.

How far should a Christmas tree be from the fireplace?

At least 3 feet from the fireplace, and from radiators, heat vents, space heaters and candles too. That's the NFPA's recommendation.

What do you do with a Christmas tree after Christmas?

Take off every decoration and use your city's curbside pickup or drop-off recycling program, where trees are turned into mulch. Don't burn it in the fireplace, and don't leave it in the garage or against the house.

The Five Rules of Christmas Tree Care

1.     Buy fresh. Bend a needle before you buy.

2.     Cut fresh. 1 to 2 inches off the bottom, straight across, right before it goes in the stand.

3.     Water every day. Never let the stand run dry.

4.     Keep it 3 feet from heat and away from real candles.

5.     Take it down when it's dry. Whatever the calendar says.

Do that and your tree will still smell like a forest on Christmas morning, and it'll be safe all season.
