Yes, I think I'm okay. We have a fake tree, so no live branches for them to be released from.This is copied and pasted from a website from the UK called Somerset Live (dot CO dot UK)
Is it unlucky to keep your Christmas decorations up?
Epiphany is traditionally the end of Christmas and so you should have taken your Christmas decorations down by then.
The story goes that tree-spirits live in the greenery, such as holly and ivy, used to decorate homes.
Over Christmas, this greenery provides shelter for the spirits during winter. Once Christmas is over, however, they need to be released.
If they are not released in time, the greenery and vegetation might not return, threatening agricultural failure and famine.
Since your tree is not the old fashioned live type, this may not apply to you
