I've always suspected that we had raspberry bushes in our backyard. Jim's always hacked the brambly mess down to the ground in the spring, so I've never been sure. This year Jim was a little slow and as a result we have a very large raspberry patch that is brimming with berries!
Since they obviously can grow with little or no attention, the only flaw is that raspberries can be very invasive and spread where ever they please. I'm told this can be limited by planting them in large bottomless containers. You dig a hole large enough to accomodate the bottomless container and then plant the raspberry bush in this. Once the dirt is filled in, all you would see is about an inch of the container peeking above the soil. I'm hoping to try this soon.
I freeze fresh picked raspberries, strawberries and blueberries as is, with no fancy preparation. I imagine, I'll do the same with the currants and gooseberries when the time comes.
Speaking of currants, despite all the transplanting, they have some berries and the berries are beginning to ripen! I didn't expect that to happen. I think its a testament to the wonders of vermicomposting!
