Container Raspberries

I got this raspberry shrub about a year ago and planted it in my container garden. Actually, the so called container is made of 4 concrete blocks filled with 100 liters of soil. I´ve used this raised bed before to grow my cukes . Now, it´s taken over by the respberry schrub and it´s growing so tremendously that I have to use this raised bed alone for the main plant and its newbies... but the result is bigger  and sweet berries...
