how to keep christmas tree alive

I'm not sure if you're asking how to keep a real Christmas tree alive, or how to keep the idea of a Christmas tree alive. If you're asking about the real tree, there are several things you can do to keep it healthy and thriving. First, make sure to water it regularly and keep it away from heat sources. You can also try giving it a little bit of fertilizer or plant food every now and then. As for keeping the idea of Christmas alive, I would say that the best way to do this is by embracing the spirit of the holiday and sharing it with others.
