Caring for an Outdoor Artificial Tree in Rain and Snow

Why rain and snow matter for an artificial tree

An outdoor artificial tree is a plastic and metal structure, so it will not rot or wilt like a real tree. The main concerns are water getting into the light system, snow weighing down branches, and wind tipping the tree over.

Manufacturers that sell trees with outdoor-rated lights test them against moisture and temperature changes. The ENERGY STAR program notes that decorative light strings labeled for outdoor use are subjected to weathering tests. That means the sockets and wiring are sealed more tightly than indoor strands.

Even so, the tree itself is only as weatherproof as its weakest connection. The spot where a branch meets the main pole, or where a light plug joins the next section, can let water in if it is not protected. Learn more about outdoor-rated artificial Christmas trees.

How rain and snow affect the tree

Rain can pool around the base and in the joints of the tree stand. If the stand is made of uncoated metal, that moisture can lead to rust over several seasons. The needles, however, are usually PVC or PE, which do not absorb water.

Snow is a different story. A few inches of light snow is fine, but heavy wet snow can add several pounds to the top of the tree. That can bend the branches, strain the hinge points, and shift the center of gravity. A tree that is not anchored can fall over.

Rapid temperature changes, like a freeze after rain, can make plastic parts brittle. If you live in an area that cycles between rain and freezing, inspect the tree more often. For wind protection, see securing an outdoor tree from wind.

Inspect lights and connections every year

The U.S. Fire Administration recommends inspecting holiday lights each year and throwing away any strand with frayed or pinched wires. That rule applies to outdoor trees even if the lights are built into the tree.

Check the connectors between sections. Look for cracked gaskets, bent pins, or any sign of water intrusion. Use a flashlight to see inside the sockets if you can.

Before you plug the tree into power, make sure the outlet is a GFCI. This device cuts power if it detects a short, which is essential for a damp outdoor setup. See GFCI outlets for Christmas trees for more.

What to look for in an outdoor light set:

- Outdoor rating on the packaging or spec sheet

- Sealed connectors with rubber or silicone gaskets

- A UL or ETL safety mark on the light string

- ENERGY STAR certification for energy savings and durability

Prepare the tree for a storm

Before a storm, take down any loose ornaments that could become projectiles. Move potted plants or furniture away from the tree's base.

Secure the tree to a fixed object. If it is on a porch, use a wall anchor or a heavy stand weight. For a yard, drive a stake into the ground and attach a guy wire to the trunk. The taller the tree, the more it needs a low center of gravity.

Unplug the tree and all connected lights before the storm arrives. This prevents a short circuit if water gets into the wiring.

If you have a tree skirt or a cover, remove it so rain can drain away from the base. For tips on anchoring, see anchoring a tree to a wall and how to keep a tree from tipping over.

After the storm: dry and check

Once the storm passes, inspect the tree from the base to the top. Shake or brush off snow before it freezes into ice. Use a soft bristle broom and work from the bottom up, lifting the branches gently.

Wipe down the light connectors and the tree trunk with a dry cloth. If any connector shows water droplets, let it air dry for at least an hour before you reconnect power.

Check the branches for cracks or bent hinges. If a branch is loose, re-seat it in its slot. If a light section is dark, test the connection and replace the fuse if needed.

If the tree sat in water, check the base for standing puddles. Tilt it slightly to drain, or remove the base cover if your model has one. Learn more about drying a wet tree before storage.

Choose a tree that can handle the weather

When you shop for an outdoor artificial tree, look for a label that says 'outdoor use' or 'weatherproof'. That means the branch materials and the light systems have been tested against moisture and UV exposure.

Pre-lit trees save you from having to string lights, but you must confirm that the light connectors are sealed. If the tree is unlit, you can pair it with ENERGY STAR certified outdoor light strings that have a three-year warranty and are built to last.

For a large porch or yard, a tall pre-lit tree with a sturdy metal stand is a solid choice. For a small balcony, a shorter tree that you can store indoors after the season might be easier to protect. See the best pre-lit Christmas trees and best unlit Christmas trees guides.

What to pick for your use

Questions

Can I leave an artificial tree outside all winter?

Yes, if it is specifically rated for outdoor use and you take steps to secure it against wind and snow. Disconnect the lights during storms and dry the tree after heavy rain.

How do I get snow off my artificial tree?

Use a soft broom or a gloved hand to gently lift the snow from the branches, working from the bottom up. Avoid pulling on the tips, which can bend or break.

Is it safe to run an outdoor tree's lights in the rain?

No, unplug the tree when it is not being viewed, and make sure the outlet is GFCI-protected. If rain is expected, turn the tree off before the storm hits.

Will rain ruin the lights on a pre-lit tree?

Only if the connections are not sealed. Look for an outdoor rating and check that the connector gaskets are intact. Wipe and dry them after any exposure.

What should I do if a branch breaks after a snow storm?

If the branch is still attached, try to reset it in its hinge. If it is cracked or detached, you may need to replace that section, or contact the manufacturer if the tree is under warranty.
