It always amazes me why people give a crap what other people do. That said, I always leave my tree up at least until January 6 (12th night), but then it comes down when all the needles completely fall off or when I feel able to add another task to my day, whichever comes first. I try to do it by January 15, the last day it will be collected for mulch by the local water department, but sometimes I miss that so chop it up and put it with yard waste for collection. I don’t decorate much other than the tree so no outdoor decor for the neighbors to judge me about 😏
