From twinkling lights to illuminated walkways, decorating trees during the holidays is a beloved tradition—but it’s also a practice that, when done improperly, can harm the very trees you’re trying to highlight.

Before you string a single strand, here’s what certified arborists recommend when it comes to holiday lights and tree safety.

DO: Use Tree-Friendly Lighting Techniques

• Choose LED Lights: These produce less heat than traditional bulbs, reducing the risk of damaging bark or drying out limbs.

• Use Soft, Flexible Straps or Clips: Avoid wires, zip ties, or anything that tightens over time and restricts growth. Instead, opt for soft, reusable light-hanging clips or padded wraps.

• Keep Lights Off Young Trees: Newly planted or thin-barked trees are more sensitive. Wait a few seasons before adding weight or lights to these specimens.

• Test Before You Hang: Make sure all strands are in working order before installation to avoid re-wrapping and over-handling the tree.

DON’T: Use Nails, Staples, or Wire

• Avoid Penetrating the Bark: Nails and staples damage the bark and can allow pests or diseases to enter, weakening the tree’s natural defenses.

• Don’t Wrap Too Tightly: Tightly wrapped lights can restrict branch growth and cause scarring. Leave enough slack to accommodate natural movement in wind and growth.

• Don’t Leave Lights Up All Year: Leaving decor up long-term increases the risk of bark damage and can lead to moisture build-up, rot, or tangling with new growth.

Decorate Responsibly, Especially on Large or Valuable Trees

If you’re decorating mature trees or large focal points on your property, consider a quick inspection by an arborist to ensure the tree can safely bear the extra weight or contact. This is especially important if you’re planning to climb or use ladders around the tree.

Bonus Tips for Tree-Safe Holiday Displays

• Add uplighting or ground-based spotlights instead of wrapping branches for a dramatic and tree-friendly alternative.

• Use battery-powered lights on trees that are far from outlets to reduce cord clutter and trip hazards.

• Avoid decor that hangs or swings in strong winds, which can snap small branches.

Protect Your Trees This Holiday Season

Holiday lights should enhance your landscape—not damage it. With a few precautions, you can enjoy a beautiful, festive yard without compromising your trees’ long-term health.

If you spot signs of limb stress, decay, or previous damage while decorating, contact Executive Tree Care for an expert assessment or pruning before continuing your display.
