How to keep a real Christmas tree alive
Updated By Jeremy Monaghan, Elf in ChiefTo keep a real Christmas tree alive, there are four rules and no more:
- Cut about a centimetre off the trunk before it goes in the stand.
- Stand it in water within the hour, and keep the cut end under water from then on.
- Top the stand up daily. A fresh tree can drink 3 to 4 litres in its first 24 hours.
- Keep it out of direct sun and away from heaters and air-conditioning vents.
Do those four and your tree will see out four weeks comfortably, and often longer. The rest of this guide is what to do when the tree stops drinking, why it browns, and what not to put in the water.
Cut the trunk, then get it into water fast
Sap is the problem. Once a tree is cut, sap seals the base within hours and the tree stops drinking, which is why a tree can sit in a full stand and still dry out.
Take about a centimetre off the bottom with a straight, level cut, and get it into water quickly. If the base has dried out again before you stand it up, take another slice off. Every tree we deliver gets a fresh cut on the day, so if it goes straight into a filled stand you can skip this entirely.
Keep the stand full
The first two days matter most. A fresh tree can take 3 to 4 litres in the first 24 hours, so check it twice on day one.
- Stand capacity: at least 2 to 3 litres. The TreeMate we deliver holds 9 litres, which buys you some slack.
- The rule that matters: the cut end must stay under water. Expose it even briefly and it starts to seal again.
- If the water stops dropping: the base has sealed. Lift the tree out, take another centimetre off, and put it straight back.
A tree that has stopped drinking is very hard to rescue once it is decorated, which is the real reason to get this right in the first week.
Keep it away from heat
An Australian December is the real enemy here. The usual suspects, in order of how much damage they do:
- Direct sun through a window. Worse than anything else in the room. Keep the blinds down on hot days.
- Heaters and fireplaces. Obvious, and still the second most common mistake.
- Air conditioning. The one people miss. A vent blowing across the tree, cold or hot, dries the needles just as effectively.
On a run of hot days, keep the stand filled to the brim and expect to top it up more than once.
How long can a tree go without water?
Hours, not days. A cut tree left dry begins to seal and dry out within about four to six hours, and once the base has sealed it will not drink properly again without a fresh cut. That is why the gap between delivery and standing it in water matters more than anything you do in week three.
Why a tree goes brown
Browning is almost always thirst, heat or age, in that order.
- Not enough water: the tree browns from the inside out.
- Sun or a heat source: it browns on the side facing it.
- Cut weeks ago: it was already on the way there when it arrived.
Brown tips on arrival are a different thing. That is sun damage in transit, and water will not bring it back.
Why needles drop, honestly
Most of the needles you sweep up were knocked off carrying the tree in. Give it a gentle shake outside before it comes through the door, or wrap it in an old sheet for the trip down the hallway, and you will save yourself most of the vacuuming.
After that, needle drop is a hydration story. Heat stress is the usual trigger: a tree brought into a warm room and parked near a heat source loses moisture faster than it can replace it, and drops needles prematurely as a result. Water and position fix nearly all of it.
What to put in the water
Plain tap water. Not sugar, not aspirin, not lemonade, not a commercial preservative. None of them outperform clean water in a stand that is topped up daily, and some are worth avoiding altogether if you have a dog that drinks from the stand. Our guide to real Christmas trees, dogs and cats covers that.
How long it will last
We recommend planning on four weeks, and a well-watered tree in a good spot often goes longer. That covers the season comfortably if the tree goes up at the start of December. If yours is not lasting, it is nearly always one of three things: the base sealed before it reached water, the stand ran dry, or it is sitting in the sun.
If your tree is genuinely not what you expected, get in touch. Our Satisfaction Guarantee covers a replacement or a refund, and we would rather hear about it in week one than in January. When the season is over, book a collection and we will take it back to the farm to be mulched.
FAQs
How often should I water a real Christmas tree?
Check it daily, and twice a day for the first couple of days. The water must never drop below the cut end of the trunk. A fresh tree can drink 3 to 4 litres in its first 24 hours.
Do real Christmas trees need water?
Yes. Once a tree is cut it has no roots, so the stand is its only water supply. Without it the needles dry, brown and drop, usually within a week.
How long does a real Christmas tree last without water?
Only a few hours before the cut end starts to seal, and about four to six hours before it begins drying out in earnest. After that it needs a fresh cut before it will drink again.
Why is my Christmas tree going brown?
Not enough water, too much heat, or a tree that was cut a long time before you bought it. Check the stand first, then look at where the tree is sitting.
What should I put in the Christmas tree water?
Plain water. Sugar, aspirin and shop-bought preservatives make no useful difference, and clean water does the job.
How do I stop my tree dropping needles?
Shake it outside before bringing it in, keep the stand full, and keep it away from heaters, vents and direct sun. Most needle drop is either transport or thirst.
How long does a real Christmas tree last?
We recommend planning on four weeks, and with daily water and a spot away from heat a tree often goes longer.
Can I use LED lights on a real tree?
Yes, and they are the better choice because they run cool. Check the leads before they go on and switch them off overnight.
