normally if you use a whole phrase in a poem and it isn't obvious who it's from or about, then credit that part in a footer.
if the poem's an obvious homage then i wouldn't call it plagiarism and see no need to credit anything. william carlos homages are obvious ones where everyone has done one. a parody doesn't need to be credited. if you write a poem about a poet and use a line of theirs in the poem, i wouldn't call it plagiarism. usually plagiarism is something the writer doesn't want you to know about.
an example would be me writing a poem and starting it
Romeo, Romeo, wherefore art thou
then going on to say
romeo, romeo, wherefore art thou
there is no Romeo, only some lothario ....blah blah blah
the 1st line isn't plagiarism because it something every poet has read before and knows about, i suppose it should be credited but i doubt someone would hang you for it.
