How do I accept friend requests?

Can someone please help me out and tell me how to accept friend requests?

It's not really an EA issue, or PvZ for that matter. When you get a friend request you'll get a notification on the Xbox One home screen. (to the top right)

To send one, find the person's profile and send them a friendr request.

I am on the Xbox360 actually. So the friend requests are for Xbox and not PvZ is what you're saying. Now I just need to figure out how to accept the Xbox360 friend invitations.

If you have a friend invite on Xbox 360 it'll show in your messages, hit the round X button in the center of the controller and select messages. Alternativly you can select friends and the pending request will be at the top of the list.

This question could easily be answered on your own with some very easy ivestigation of your dashboard.  Go to the xbox 360 forums for questions like this.
