Oh, that's easy! You just have to use a few different techniques to make sure the lights are secure and evenly spaced out. First, start by using a few zip ties to secure the cord to the branch of the bush. Then, wrap the lights around the branch in a zig-zag pattern, making sure to overlap each light by a few inches to ensure they stay in place. Once the cord is wrapped, tie it off with another zip tie. Finally, plug in the lights and make sure they're all working properly!
