Raspberries

I've got a raspberryPatch It's been there for about three years nowI 've got an area there where they never came out this  year Would it be okay to put some new canes there this year thanks

Me, is this the same area that you were posting pictures of raspberry leaves last year as you thought there was something wrong with them? If so best to avoid that area, also why are you replacing them after 3 years, a raspberry area usually lasts much longer than that?
