How to Install Fairy Lights in a Tree

Hanging fairy lights in a tree can create a beautiful and magical ambiance. Here’s a step-by-step guide on how to do it well and how to do it safely:


Choose the right fairy lights: Select fairy lights that are designed for outdoor use and are suitable for trees. Make sure they are waterproof or weather-resistant to withstand the elements. The Commercial Fairy Lights we sell here at Mr Festoon Lights are all designed for this exact purpose. They are a little more expensive than ones you might find in Bunnings but that is because they are simply much better quality. We only use UV resistant rubber cabling with higher output LEDs and top of the range Meanwell Drivers.


Plan the layout: Decide where you want to wrap the fairy lights and plan the pattern or design you want to create. Consider the height, branches, and shape of the tree to determine the best arrangement. Consider branch thickness and accessibility to the branches as well as how dense you want to wrap the tree with lighting.


Measure the length: Measure the distance between the power source and the tree to ensure the lights will reach. It’s important to have access to an outdoor electrical outlet or use an extension cord specifically designed for outdoor use. When running the power out to the tree it is best to do this at low voltage for safety reasons so the driver should be close to the power source and the cable running out to the tree should be low voltage. Fortunately we have made this task easy by providing extension cable to just click and connect to our system.

Test the lights: Before hanging them, plug in the fairy lights to make sure they are working properly and you are happy with colour temperature etc. to save time changing after they are installed. Replace any faulty or broken strands.

Gather the necessary equipment: You will need the following items:


Ladder: Use a sturdy ladder tall enough to reach the branches where you want to hang the lights. Always have help to hold the ladder or if the branches are quite high it is best to call for qualified help with the installation.

Cable ties or hooks or velcro: While wrapping the branches will help to secure the lights for the most part themselves there may be circumstances where you need to secure them with another bit of hardware. These will be used to secure the lights to the branches. For the most part we advise to use garden velcro as this will not cut into the tree branch as it grows.

Secure the lights to the branches:


Start at the bottom of the tree and work your way up. Climb the ladder safely and have someone hold the ladder for added stability.

Attach the fairy lights to the branches by wrapping firmly but not too firmly to allow for growth of the tree over time. Wrap the velcro or tape around the lights and the branch near the end of the runs, pulling them tight to secure the lights in place. 

Be gentle while handling the lights to avoid damaging them or the branches and always account for tree growth over time and movement of the branches in the wind.

Distribute the lights evenly: Space the lights out evenly along the branches to create a balanced and aesthetically pleasing display. You can follow the natural shape of the tree or create your desired pattern. We usually recommend a spacing of around 10-15cm between each wrap to give a good level of density of fairy lights.

To help navigate the branches we also recommend using our fairy light directional splitters. The can help to split the lights off into several directions to follow the branches of the tree.

Test the lights again: Once all the lights are in place and the cords are secured, plug them in to ensure they are functioning properly. Make any adjustments as needed.


Safety precautions:


Ensure the lights and electrical connections are designed for outdoor use.

Only use an outdoor electrical outlet or a waterproof extension cord. Make sure that the transformer is also rated for outdoor use just like Mr Festoon Lights ones always are.

Do not overload the electrical circuit.

Be cautious of nearby power lines and avoid contact with them.

Keep the lights away from flammable materials and ensure they are not touching dry branches or leaves.

Remember, safety should be your top priority when working with electricity and ladders. If you’re unsure about any step, it’s always a good idea to consult a professional or seek assistance.
