why do my christmas tree lights keep blowing fuses

I'm afraid I don't have an answer for that. But I do have a few suggestions. First, try to make sure that your tree's electrical wires are not tangled or knotted up. This could cause a short circuit and blow a fuse. Also, make sure that the lights you are using are compatible with the outlets in your home. Finally, check to see if there are any other electrical appliances or devices plugged into the same outlet as your Christmas tree. This could be causing an overload of electricity and blowing the fuse.
