Ash told us that "hanging lights, whether that be on your Christmas tree or in your garden, can be a little tricky if you haven’t done it before!"
To master hanging outdoor lights on trees, do it from the trunk up — this is the most widely used technique when it comes to decorating trees, according to Ash. This will also make taking them down much easier. Ideally, you want no more than three separate light strings per tree, especially if you're using an extension cord to plug them into.
If you are attempting an intricate wraparound design, make sure you have a sturdy outdoor ladder, like this highly-rated telescoping ladder from Amazon — or two ladders if you are decorating the smaller branches of a taller tree. Decorating a taller tree is a two-person job, always — you will want to have someone holding the other end of the lights as you wind (or vice versa).
If you're not confident doing this yourself, it's best to hire professional light installers to decorate your outdoor trees.
