Given the plight of the bee, I'm wondering if I create an empty hive and just let nature take its course, am I inviting trouble or creating opportunity?

I've got a hedge of hydrangeas that are covered with bees while in bloom. Was thinking that maybe if I construct a small hive in my backyard, I could do some good.

I'm not looking for anything other than to promote bees, no honey production for use. Just to help.

Is this a viable idea?

Thanks!
