Can an Ayers Pear tree received as a gift be exchanged for a Cleveland Select at any store?

I would think as long as you have a valid receipt, it shouldn't be a problem. I would call customer service to get a better answer.

Most likely if you have receipt or explain to customer service it was a gift purchased at Lowe's

Yes

I think you should call customers service ,however I think they will if some proof that it came from their store.

Yes. Even if you don't have a receipt as long as it came from Lowes

I don't know

I believe that Lowe's accepts anything they sell back to be returned or exchanged. Plants might have a certain time frame but I'm not exactly sure. The best thing to do is call the one you are trying to take it to and ask.
