How do you know when a poem is finished?
I don’t think a poem is ever really finished. I’ve revisited poems from ten or twelve years ago and amended them or rewritten them completely. Even poems that have been previously, published, I changed when putting together my last book, the x of y (Eyewear Publishing, 2018). You’re always growing and changing as a person, learning new things, gaining perspectives, fighting with new regrets. So your relationship with a poem is constantly evolving too. Any poem could feasibly change or continue from where they stand now. A poem only becomes definite by default once the poet dies.
