how to change age in pvz hero

Hey @YellowSlimey I don't believe that it is possible to change the date of birth. The best thing you can do is speak with one of our phone or chat support advisers who will be able to advise you further as to if anything can be done. 

You can contact our live support at help.ea.com.  

To request a callback or speak with a chat adviser:
