I don't know how or when this happened but I have a magic beanstalk growing in my backyard. I didn't notice this all summer, but all of a sudden this giant beanstalk has grown out of my plant. It's huge! It's up to my roof now. Is this normal? Do I cut it? Will a giant come down it at some point? This never grew like this last year, so why did it happen this year? I know we have a Jack, but I don't think he sold a cow for any magic beans that I know of.
